Alumni Testimonials

This experience has been incredible. I have been studying and practicing herbalism for 15 years and this program stands out among so many I’ve done. I am so impressed and grateful. I’ve been able to heal some things I’ve dealt with for years through what I’ve learned here. Your whole team is just awesome. This program has definitely not been easy! And I love that – the challenge is where growth takes place. Wow has it flown by. I’m soaking up these last few months of class. Thank you so much.

Audrey Barron | Class of 2024

David Winston’s program on-line offers a dynamic learning experience that explores many facets of herbal education.  In his classes David uses current medical diagnostics, evidence based research and his unique herbal experiences to build a cohesive learning program. This cross-disciplinary approach is truly a transforming experience. I truly appreciated the opportunity to sign on for the archival review and listen and watch the videos of his current classes, participate in the grad forum and receive updated information in the comfort of my home.

Sharon Niscak | Class of 2010

I LOVED David Winston’s class.  He has brains!  And clinical acumen.  I learned more from him about how to practice real medicine than I did in any continuing education class since medical school.

Rima Kittley, MD, FAAFB, ABIHM, RH(AHG) | Class of 2008

I am a veterinarian with a 100% alternative modality practice, I had been searching for a ‘higher’ level herbal course that was compatible with a busy veterinarians working schedule. I had taken introductory herbal classes, and all that we have available for veterinarians, but I needed more. David’s Materia Medica is taught at a deeper level than any of our currently available veterinarian courses. He has taught us how to develop elegant herbal prescriptions.

Cynthia Lankenau, DVM RH(AHG) | Class of 2020

I entered David’s class as a physician who knew a lot about herbs, but my goal was to learn to think like an herbalist.  David has taught me to do this!  His teaching is an amazing amalgam of scientific rigor with common sense, as well as an obvious deep love of and respect for plants.  The course is challenging and wonderful and worth every minute of those long evenings.

Wendy Warner, MD, ABIHM, IFMCP | Class of 2016

I came to the Winston 2 year herbal training program after being in clinical herbal practice for over 15 years. The education I have received in this time has far surpassed my expectations, being the most compressive herbal medicine learning experience I have had to date. I am so grateful for the time I have spent learning with David, he is a true Elder in our community and I am honoured to have had him for a teacher.

Colleen Emery, RHT (CHAofBC) | Class of 2020
Working in the herbal supplement world, this course was a great foundation for me to help improve our formulations and make sure that we are doing the best possible job creating products that are effective and true to the herbal tradition. Not previously a clinician, this course has given me the confidence to start working with clients and I feel much more connected with the greater herbal community having learned from David. I really appreciated having such a diverse array of earnest students as my classmates. From Ayurvedic practitioners, acupuncturists and TCM practitioners, to MDs, massage therapists, to veterinarians I learned a lot from my classmates in addition to the mountain of learning we received from David. Thanks so much for a well organized and thorough program!
Tim Yarborough | Class of 2020

If you are serious about an herbal education and want to invest your time in learning from a genius herbalist, this is the place to be.  David Winston introduces the student to an herb’s historical use, but also shares the importance of staying abreast of the most up-to-date scientific findings regarding that herb.  He is an inspiring, kind teacher who has elevated me into becoming a much better, more confident herbalist.   My only regret is that this two-year program is ending.  Thank you, David Winston!

Donna Brower | Class of 2020

This is not a “soft course” for dabblers. Bring your best, for David Winston will always bring his. Undoubtably one of the most gifted herbalists of our time, or any time, I think David’s greatest gift may be as a teacher. I am constantly in awe of his, and his team’s, dedication, professionalism, and wealth of knowledge.  I was an online student, in what may have been one of the more challenging years, a.k.a. 2020 and the COVID-19 epidemic. But every week through personal and  technological challenges, David persevered, and laying his years of research and experience out to eager listeners. He was challenging, provoking, and demandingly encouraging.  I feel that I am going into the world of herbal medicine with possibly the very best foundation that exists. This course is possibly the most important and rewarding academic experience I have ever had.

Rachelan Griffin | Class of 2020

It is hard to imagine myself being where I am today if I had not enrolled in David Winston’s program. This class starts you at square one, and slowly builds your panoply of herbal knowledge – assuring you will acquire the confidence and knowledge to better both yourself and one’s community. What I liked most about this program is David’s straightforward and effortless way of teaching. David truly demystifies herbal medicine, as he has spent 50+ years studying, 40+ years practicing and bringing esoteric knowledge to those wishing to study with him. Words cannot grasp the gratitude I have for both David, his faculty and what this program has done for me.

Robert Sena | Class of 2020

I am a recent graduate of David Winston’s herbal program.  I have learned so much from this herbal program and plan to continue on to David’s graduate program.  David is a fantastic teacher and herbalist and I am grateful for the plant medicine knowledge gained in his program.   I look forward to serving my community with herbal medicine and couldn’t be more pleased with the level of knowledge passed along from being a part of the program and community!  I encourage anyone pursuing a career in herbal medicine to join this program!


Linda Thompson | Class of 2020

I attended six national conferences on herbalism and heard many brilliant and inspiring speakers before selecting the Center for Herbal Studies with David Winston. I couldnʻt have chosen a better program. This program is for anyone interested in diving deep into the study of plants and their uses for health (mostly human uses and some animal uses). Initially I was not happy to find that 90 percent of the plants covered in the program are foreign to where I live in the Pacific. Fortunately, it has been my experience that studying those 250+ foreign plants prepared me to experience and investigate the plants that are growing in my local area through a more sophisticated lens.  Iʻve been able to expand my herbal formulary considerably.  The course stands on scientific evidence and some indigenous wisdom in a way that Iʻve developed broader skills in evaluating published material / statements about herbal medicines. In addition to studying plants the program also provides training in medicine making, TCM and botany. Every part of the training is useful in real life.

Kaimalani Boyd | Class of 2020

As a veterinarian, David’s class has given me invaluable insight in the blending and weaving of Chinese with Western herbs.  It has raised my herbal prescribing to a higher level. The triune system is brilliant, not only as a treatment but as a teaching tool.  I strongly recommend this class to any serious herbalist.

Cynthia Lankenau, DVM | Class of 2020

This is the first time in my life than in the end of the study I feel confident and capable of doing what I tried to learn. I really feel there was an aim that is absolutely accomplished. I don’t know where life will take me from here but I feel grateful for all these moments I felt there were answers to questions I had since I started with herbs, more than ten years ago. I feel grateful for all these “aha moments” that made my heart beat faster and my brain work in new paths. I already feel I will miss you all that were so close to me for two whole years , although in the other end of the world…

Eleni Christoforatou | Class of 2020

I have enjoyed David Winston‘s two-year Clinical Herbalism program so much. I consider myself a novice herbalist and although I have known many of these plants, I never really understood them as well as I do now. David weaves history and science and mystery and magic all together to create a body of work that is beyond compare.And in this crazy world when it’s hard to separate truth from hyperbole, one thing I really appreciate is that I know that if David says something is true I can “take it to the bank”. I really admire and appreciate his commitment to this subject and to his students. In addition to David’s amazing classroom teaching, the written information that we received  is a tremendous resource that I will use forever more. Additionally, the other lecturers that are involved with this class are tremendously  talented as well and I enjoyed their input very much. I really can’t imagine not doing this course; it has been well worth the investment

Jamie Moran, DVM | Class of 2020

I enrolled in David’s program because my self-study of herbalism had reached a plateau. I wanted to get to the next level, and over the two years, my knowledge was raised by several levels. The program is comprehensive, covering Western, Chinese, Ayurvedic, Middle Eastern and traditional medicine. This broad approach gives me the confidence to consider herbal protocols in every day life. I have learned so much, and I appreciate the opportunity to study with David. I highly recommend the 2-year program.

Dea Zufelt | Class of 2020

I came into David’s program as an eager beginner thinking that I knew something about herbalism. Two years later I realize that there is a much deeper complexity to herbal medicine that I ever imagined. I feel very fortunate to have had David and his ensemble provide me with such a comprehensive foundation that weaves together the extraordinary diversity of fibers, textures, and colors of the herbal world into this one delightfully unique program. It has been a privilege opening my eyes to these perspectives. I have learned and gained beyond my expectations and feel fully confident recommending this program no matter where you are along your herbal journey.

Stephanie Collins | Class of 2020

The David Winston herbal school has opened to me a world very little known of to many people, I endeavor  to pass the knowledge  and help to many others.

Nokuthula Mutumhe | Class of 2018

If you want to learn clinical herbalism – this program is the way to go. David Winston is a legend in the field, with 30+ years hands-on clinical experience in herbal medicine and a wealth of knowledge of many of the great old traditional medicine schools. His approach is balanced between science and tradition – including both and bridging them in an experience- and evidence-driven way. I feel that David is opening his students’ minds and hearts through his inspiring teaching, including a good ounce of “life-counseling” on the side. His knowledge is a true treasure, shared freely for a more than reasonable fee. It will help you manage your and your family’s health better, help the people around you, it is an add-on for any job in healthcare and/or wellness – or can become a stand-alone professional orientation. Herbs are powerful tools for caring for those various weak spots our bodies all have, so they will not come to haunt us as we age. Learn and be amazed.

Betina Thorball | Class of 2018

For me the two year program was an awesome experience!  It opened my eyes to so many things.  I am thankful for the experience and knowledge I gained. Now I am better able to help myself with my own health and other people or clients in the future.  Thanks so much Mr. Winston and Mrs. Frost!

Teresa Arndt | Class of 2018

David Winston is a living national treasure in herbal medicine, and his knowledge of herbs from each of the major herbal traditions is unexcelled. He combines a practitioner’s experience with an understanding of how to get the optimal benefit from several hundred worldwide herbs. Most importantly he has come up with a way of bridging the different energetic systems of Chinese Medicine, Ayurveda, traditional and European herbal traditions so that herbs from each can be intelligently combined in a single formula. I know of no other herbal program that deals with this extensive a worldwide materia medica in such depth.

Karen Vaughan, MSTOM, RH (AHG) | Class of 2008

We have two communities, onsite and online, which join together every week in the classroom but I never feel like I’m “learning at a distance”. On the contrary, thanks to the live chat, I  feel as though I’m right there in class. Everything has been done so well and so carefully by the school that, even though this is the first time the class has been offered online, I think it’s been very successful. I feel really  privileged to have been part of this class.

Lesley Raeside | Class of 2008

My three years studying with David Winston have, truly, catapulted my ability to assess and provide remediation to the patients I serve.  As a naturopathic physician, my capacity for success is solely dependent upon the knowledge I’ve gained and the application of that knowledge.  David’s classes have elevated my talents to a level that would not have been possible without his tutelage.  Although I’ve attained a formidable educational background in natural health from many different institutions, David’s program is at the forefront of clinical relevance and application to me and my patients.  In my opinion, it is the best program available in botanical medicine.

Glenn B. Gero, N.D., R.N.C., M.H., C.E.S., C.L.C | Class of 2004

This online/live course has been fantastic. It has allowed me to keep up with my very busy practice and allowed me to sharpen my skills without having to travel. It has been a blessing to me and to all of my patients as well. David has a wealth of knowledge, is a great teacher and the handouts are excellent resource materials. I am thrilled to have had this opportunity.

Dr. Cindee Gardner | Class of 2008

From David Winston I learned an impeccable integrity of practice, demanding standards of looking at the whole person, and intimate knowledge of a 300-plant materia medica. Our class, whether on-site or online, has been a community, puzzling together over our triune formulas and case histories. This is an international web of students–from a dozen countries–present in the classroom over our two or three years together. In class, we learned the heart and landscape of David’s unique experience with herbs from Eastern, Native American, Chinese, Ayurvedic, and Middle Eastern herbal traditions. David stands out as a synthesizer and innovator of healing traditions and disciplines, a master teacher in herbal practice, an historian of the Eclectic and Physiomedicalist movements that shaped American herbal practice. As a founding member of the American Herbalist Guild, he helped lay the foundation, standards of practice, and educational mission that supports the growth of herbal practice in the United States.

Joan OBrien | Class of 2016

This is an exceptional, well-structured course on the systematic use of herbs to improve health. Although I am a former chemistry-teacher and current engineer, I had been studying herbal medicine independently for nearly 15 years before taking this course. My goal was to gain some additional background in order to teach about the medicinal uses of herbs. The two-year course has sparked my interest to the point where I am now interested in seeing clients. I have long regarded herbs as far more than alternative medicine; they should be a significant part of mainstream medicine. This course goes a long way toward making that happen. The use of standard medical terminology, scientific evidence, and a comprehensive, systematic approach makes this course a rigorous, solid foundation upon which to build your skills. Most importantly, however, David’s rational, evidence-based approach and extensive experience keep the course exciting while equipping the students with the skills necessary to properly evaluate research and think about herbal medicine critically and objectively.

Andrew Snyder | Class of 2014

David’s herbal studies program is a wealth of information. Becoming a certified herbalist is an invaluable addition to my nutrition practice.

Leslie Weinman | Class of 2016

This is a highly professional school which helps to develop knowledgeable, responsible, and effective clinical herbalists.

Lorraine M. Harwelik | Class of 2012

The grad program has been an amazing addition to the two-year program. It sharpened the focus and pulled so many things together on specific topics. I feel like this really deepened my understanding and gave me the foundation for a lot more practical application. I’m truly grateful to David and everyone else who made this program happen! It’s been a remarkable experience.

Timothy Whittemore | Class of 2010

David’s herbal studies class is THE most valuable educational experience I have had in my lifetime. The knowledge I have gained from this class has inspired me to continue to pursue my goal of vibrant good health into the wiser years, and to be a source of information to help others who come to me for advice to do the same.  I will be a student of herbal studies and related topics for the rest of my life. Thank you, David, for this gift of knowledge of the gifts and medicines from the earth.

Elizabeth Stevens | Class of 2010

I’ve always been a student, but David gave me an important foundation for learning. His approach to plant medicine using an energetic system of formulation is invaluable. My life wouldn’t be the same in my practice, the woods and fields or business without my teachers. Thanks to David and the Plants.

David Harder, RH (AHG) | Class of 1998

In the course of my studies in botanical medicine over the last 8 years, I have been exposed to a number of exceptional teachers and practitioners. None more exceptional than David whose vast knowledge and passionate dedication to herbal medicine has inspired those us lucky enough to have studied with him.  He is a treasured resource.

Bob Turchyn | Class of 2010

I started the herbalist training program at David Winston’s Center for Herbal Studies in 2008 with only a very basic understanding of natural healing and herbalism. I can honestly say that I was astounded at the education I received not only on 400+ plants, their therapeutic uses and botanical make-up, but through David’s incredible knowledge of diseases and their treatments. His clinical expertise blended with his ability to bridge the gap between western medicine and traditional systems provides an invaluable, real-world approach to treating clients who are often working with practitioners from both areas. The field of herbalism is vast but David’s program pulls it together in a way that gave me confidence to start my own practice soon after graduating. To anyone who wants an intense, comprehensive study of herbalism, I recommend these program without hesitation.

Wendy Whiting | Class of 2010

The measure of a school and a teacher is how well they prepare you for your profession. David Winston, in Japan, would be a “national treasure”. His broad base of multi-cultural herbal knowledge, and especially the traditional medicine, is unique. He is simply encyclopedic in his ability to access his years of learning and answer any question. His teaching method is infectious curiosity, well-organized units that build on each other, and that culminates in an excellent preparation for clinical practice: how to do effective case histories, how to put together effective and balanced herbal formulas, how to use nutrition / supplementation / mind & physical therapist and lifestyle changes to pull together an excellent Protocol for your client.

Serious, and jam-packed as each class is, you leave each class inspired and excited. And, David has an excellent sense of humor. I am constantly reminded of how David Winston is held up for special respect in the world of herbalists whenever I go to important herbal conferences. He is in constant demand as a regular guest lecturer at herb and naturopathic schools of higher learning here in the States and around the world.

I am a graduate of David’s school and graduate clinical course, and have my professional designation from the American Herbalists Guild. I have been in practice since 1996, and at age 70, in 2012, I am moving to Key West and closing my practice. David’s excellent school enabled me to help a lot of people along the way.

Constance Miller | Class of 1997

My experience with David Winston’s online clinical herbalism course was fantastic! David is thorough, professional and honest about his knowledge and experience with the herbal world. The Materia Medica was extensive and very comprehensive. His ability to compile massive amounts of clinical and historic information on the uses, contraindications, dosages along with climate and anecdotes on the 100’s of herbs in the materia medica is a continued wonder to me. I honor his dedication to the preservation and expansion of Herbalism and over the 3 years of study with him have grown to trust his opinion which was always clearly stated if it was either his opinion and/or based on some experience or clinical trials. His clarity and dedication is to be commended. I highly recommend this course.

Beth Power | Class of 2009

David Winston’s program has exceeded my expectations as a student. The online program makes me feel as if I’m actually in class, with access to a chat room, the ability to ask questions, and good tech support. David’s wealth of knowledge and willingness to share his experience provides a solid foundation for anyone who has an interest in herbal medicine. The materia medica of more than 300 herbs is extremely thorough and an invaluable reference. David not only gives us an understanding of the herbs themselves, but of physiology, how the energetics of the body and herbs work, and reviews of pertinent clinical studies throughout the program. And above all, David has taught us that good herbalists treat people, not diseases.

Sue Bara | Class of 2012

David’s 2-year Herbal Studies was the ABSOLUTE best class ever.  It is so much more than studying the herbs.  His knowledge and effective communication of the plants and their uses is amazing.  He is truly brilliant and I am proud to say that I studied with him.

Brenda Sahlin, DC | Class of 2010

My 3 years at DWCHS have given me the knowledge and confidence to begin teaching others how to make positive changes in their health. The courses are a perfect blend of extensive worldwide materia medica, formulation, Q&A, live case studies, and much more. I am truly grateful for this unique and in-depth learning experience.

Karla Parker | Class of 2010

The wealth of knowledge presented by David through the Center for Herbal Studies is truly amazing. It has expanded my pharmacy practice by adding insight into the traditional roots of medicine as well as nutritional and lab work analysis. I am able to answer questions and offer advice with a new confidence.

Anita Schweizer, RPh | Class of 2010

David has taught me and expanded my knowledge with this class.  I have not only learned about what the herbs do but also how to put it together in a formula which I have not learned with my other teachers.  Without taking his class I would not be practicing herbal medicine with pets and people today.  I am glad I have found his school to be able to learn from someone with his expertise and knowledge.

Jeanette Costa | Class of 2010

I have been so fortunate to have been in David Winston’s class. I am constantly amazed at the amount of knowledge David has on any number of given subjects. He has been so helpful in so many different situations and to have him as a resource is priceless. And I must say, when he tells a story, I get chills.

Lataya Howard | Class of 2010

Every week for two years, I had a date with my teacher, David Winston, the herbs & myself of course I was also Blessed to be with other students who were journeying down the same road- who have become like family to me).  This class provided me with what I needed to know to use my herbs in a more knowledgeable way. I learned the science behind the herbs, materia medica, how to prepare my herbs appropriately; I learned how to create a comprehensive herbal formula to support my client’s health using the concepts of energetics of the herbs as well as the tastes of the herbs. I learned how to do this safely & confidently! I loved the fact that we had two projects to as well as part of our requirements for obtaining our diplomas; it helped me to marry my two loves of Midwifery & Herbs. When I have a question, I still review that project with a smile on my face & gratitude for having done these projects. I have a strong foundation to speak from-this developed as a result of sitting in class every Tuesday and absorbing knowledge- not found in a book, for David is always researching and sharing his newly found knowledge with his students.

Trish DeTura, RN, Midwife, Cert RA Maya Abdominal Therapist | Class of 2006

David Winston’s approach to teaching about herbs is solid and grounded.  You will reference it throughout your herbal journey.Whether you take the class to help your family and friends or choose to practice clinically or integrate it into your health and wellness practice or business it will lay a strong foundation for you. The herbal community that is available through this connection is also wonderful. I am so glad that I had the opportunity to graduate from his two year program and to continue learning from him.

Julie Miller | Class of 2002

I graduated from David’s course in 1998 and have been a professional member of the American Herbalists Guild since 2003, and to this day I am grateful that David’s course provided me exactly the foundation and guidance I needed for the serious pursuit of herbal knowledge.

Richard Mandelbaum, RH(AHG) | Class of 1998

As an Advanced Practice Nurse, it was an honor to study herbal therapeutics with David Winston. We are so blessed to have an international expert teaching here in New Jersey. What impressed me most about David was his ability to accurately and comprehensively discuss both the Western/traditional diseases and treatment options, as well as the Eastern/non-traditional approaches to health. David is one of the most knowledgable teachers I’ve had in 26 years of nursing.

Grace Reilly, RN, BSN, MSN, APN | Class of 2002

David’s course gave me the skills to really feel confident as an Herbalist. Outstanding instruction from a top-notch faculty!

Bryan Thomson-DiPalma | Class of 2010

I am very fortunate in having David as my teacher.  He not only instructed me about the way of plants but also about life.

Jean Murphy | Class of 2010

I really appreciate the depth and breadth of the materia medica in this course, as well as specific indications for herbs. It has really helped refine my practice and in situations has helped me to choose the more appropriate, and, therefore, effective herb.

Deborah Fritter | Class of 2012

I was thrilled when I was accepted into David Winston’s two year  Herbalist Training.  For most of my adult life I attempted to be have a healthy lifestyle and read related articles and books whenever possible.  However, I wanted a stronger foundation.  I wanted to be able to understand the whys and hows…not just the results.  The two year program gave me what I was seeking – knowledge of herbal therapeutics, knowledge and history of the variety of approaches to herbal medicine and the ability to intelligently research. I moved onto the Graduate Program because I wanted to understand the ways to use and combine the herbs to form treatments.

Although I did not take the courses to become a registered herbalist, I am now and will always be a student promoting the positive impacts of alternative(original!) medicine practices. Family and friends have received the benefit of my knowledge and training. I have found the avocation that I was seeking.  And, who knows, maybe one day, with continued training, I will hang out that shingle!

Sally Handlon | Class of 2008

About 10 years ago I met David at a trade show and wanted to take his 2 year class. Well, although it took me 10 years I am amazed at the amount of new information as well as the reinforced information that has come through David and his staff. If you want to really laern about herbs and herbal medicine take this class. it is the best organized and most comprehensive class I have taken period.

Theresa M. Girolami, M.Ac. L.Ac. | Class of 2012

David Winston’s Center for Herbal Studies is the highest quality education I have received.  I’ve been to college in the ivy league and this school is top notch with their knowledge of the latest research.  The staff is also efficient with their audio-visual materials and online interface; and last but not least David Winston integrates ancient, time-tested wisdom with the latest of scientific discovery.  Thanks for such a great experience!

Adam Berry | Class of 2012

It doesn’t get much better than David and his Center for Herbal Studies. If you want a deep understanding of botanical medicines and plants, and you want it from a comprehensively scientific as well as from an ethnobotanical and spiritual perspective, there is no other person that can give that to you in the same way that David can. If you want the best education and resources that herbal medicine has to offer, you have come to the right place.

Sandy Bushberg, Ph.D. | Class of 2002

David Winston is so much more than my most beloved herbal teacher: he shared his great love of Cherokee medicine that fueled my passion for integrating western medicine with traditional methods to truly heal the mind/body/spirit. I remember David sharing his many stories in our classes of how he was drawn into the fields, and with a particular patient in mind, he would be drawn to the proper herb, as the plant spoke to him. This powerful connection between us mortals and the plant kingdom has humbled me and empowered me to see that God placed everything on this glorious earth for us to love and heal each other. Thank you David, for being the catalyst to open my eyes.

Dr. Helene Leonetti | Class of 1999

My respect for herbal medicine has increased many folds after studying at this school.  David and other faculty members nicely combine the traditional and folk information with modern scientific research to give us a complete and practical view.  This course is already helping me a lot with my herbal supplements business.

Sandeep Agarwal | Class of 2012

I just can’t express how much I appreciate all the hard work that has been put into this course. David’s volume of knowledge and wisdom is amazing to me. The online classroom, chat room, level of assistance, quality of materials, etc, etc, are top notch. I consider myself fortunate to be part of the class.

Lori Perry | Class of 2012

I love being able to attend David Winston’s Herbal Therapy class remotely. No travel, the ability to watch the videos for clarification and interacting with classmates far and wide via the chat room are among my favorite aspects.  Of course, if there was no remote program, I would be unable to attend the class, so thanks for doing the online program.  One last thing. It is great having it live rather than recordings and self-paced,  as other long-distance learning programs are set up.  It gives me the structure and discipline to be there for class and the flexibility to miss and make up if need be!

Dr. Ritamarie Loscalzo | Class of 2008

When they write about the best of the American Herbalism movement in the 20th & 21st centuries, this program will be at the top.

Rene Hersey | Class of 2008

Being an on-line student has been a surprisingly wonderful experience.  As all my other herbal classes have been taken in person, I was concerned that something would be lost in transmission.  I was also sad that I wouldn’t have the opportunity to form the relationships with other students that have, in the past, added a special dimension to studying the green world.

I am happy to report that I was wrong on both counts!  We have a lively on-line community that truly tries to support one another.  I’ve gained both knowledge and wisdom from our online discussions and nothing is lost in the transmission.

Maia Toll | Class of 2008

I really like and appreciate the effort involved in making it possible for me to study and be part of an herbal community from my home.  There is not much available to herbalists in this part of the country so it is a valued opportunity to learn and participate. Oh, the miracles of the electronic age.

Kathy Hand | Class of 2008

The wealth and breadth of information you receive from David Winston’s herbal training program is truly amazing! I found it empowering, enlightening, and feel I was given the tools I need to start using herbs effectively in my practice. David has an amazing repertoire of information to share. His class was quite literally a life-changing class for me, for I would not be doing what I’m doing today if it weren’t for his class.

Jennifer O’Hagan | Class of 1997

I watched a video 2 years ago on herbs and David was one of the teachers being interviewed. At that time I was searching for an herbalist program. The moment I heard David speaking about herbs and healing I knew I had found my teacher. Over the past 2 years I have learned so much. David Winston’s program approaches healing from every aspect of life. The depth of knowledge and information provided in this program is amazing whether it is anatomy, Chinese, botany, traditional medicine or western herbal medicine, to name a few. Besides learning about herbs, I am walking away being smarter, wiser and I feel I have grown as a person.

Much can be learned in books, yet, the program has helped me understand healing and my body at a much deeper level. Certain things cannot be learned by reading books but only can be taught by going through the experience. Thank you David for being so passionate about herbs and all your 40+ years of knowledge and wisdom! Thank you Eileen for all your hard work! I cannot say enough about this program and would highly recommend it to anyone…

…and this is why I am doing another 2 years with David Winston.

Alexandra Smith | Class of 2016

David Winston’s Herbal Studies program has been an inexhaustible wellspring of herbal knowledge and personal enrichment. David’s commitment to preserving tradition, integrating new research, and instilling a deep sense of accountability into the practice of herbal medicine provides the framework and foundation for a well rounded program. I can wholeheartedly say this in-depth course provides fertile ground for any budding herbalist to cultivate deeper awareness and understanding of the ever evolving relationship between plants and people!

Lindsay Napolitano | Class of 2014

I am British and so I cannot become qualified as a herbalist with this course but it has given me so much that I cannot get from any UK course.

This is particularly in respect to materia medica: we have learned, in great detail, almost 300 herbs and David gives exactly what I wanted – both the energetics of the plants and the scientific research. There is a huge amount of information on how best to prepare each herb, herb-drug interactions, sourcing of raw materials, and even ecological information such as which herbs are endangered and how to grow each plant. We have learned about herbs used in Western, Chinese, Ayurvedic and traditional medicine.

It is easy to tell that this course has been running successfully for many years – the syllabus is clear and comprehensive and it works well as a distance course – even for those of us who watch in the midnight hours! It will take me many more years to begin to absorb the knowledge from these two years.

Elizabeth Lines | Class of 2014

David’s two year program is very comprehensive, striking a balance introducing TCM concepts with focus on western herbalism approaches for treating the client as a whole. The program handouts and especially information provided on the materia medica sheets are outstanding.

I really enjoyed the last few months of the course putting the knowledge to work formulating for case histories. This program helped me establish confidence to move into professional practice. I highly recommend this program for motivated students.

Marc Sawyer | Class of 2016

The two year course in Clinical Herbalism is truly a treasure trove of information. For anyone interested in herbalism take this course you will not be sorry. David Winston is encyclopedic with his knowledge. David is very demanding, for good reasons. He only wants the best. Wait until he teaches the Native American portion of the course, you will see another side of him. The course is very well rounded: botany, chemistry, traditional uses, and the extensive materia medica. You will be sitting in class with doctors, chemists, farmers, therapists, grandmothers, plant lovers, you name it! This course was simply awesome!!!

Tiffany Robbins | Class of 2014

Two years ago I considered myself an herb enthusiast equipped with Google as my then primary source of herbal knowledge. Two years later I am able to create herbal formulas tailored for a person’s areas of concern.

Melba Scott | Class of 2016

From David Winston I learned an impeccable integrity of practice, demanding standards of looking at the whole person, and intimate knowledge of a 300-plant materia medica. Our class, whether on-site or on-line, has been a community, puzzling together over our triune formulas and case histories. This is an international web of students–from a dozen countries–present in the classroom over our two or three years together.  In class we learned the heart and landscape of David’s lineage in traditional medicine, along with Western, Chinese, Ayurveda and Middle Eastern herbal traditions.  We worked with a unique, large-scale Additional American materia medica.

David stands out as a synthesizer and innovator of healing traditions and disciplines, a master teacher in herbal practice, an historian of the Eclectic and Physiomedicalist movements that shaped American herbal practice.  As a founding member of the American Herbalist Guild, he helped lay the foundation, standards of practice, and educational mission that supports the growth of herbal practice in the United States.

Remember–our class is product of a 40-year teaching career.  At our best, we students carry the integrity of David’s clinical practice, his love of the plants, solid pragmatism, humility, blazing curiosity and the willingness to communicate to the patient whatever inner and outer change is necessary to be whole.

Joan O’Brien | Class of 2016

David Winston’s course is fin-nominal!  I was worried it  would be too much and even though the material came at me quickly, I found I was able to adapt and improve my learning skills readily. However  it is great!  I’ll walk away with skills I acquired and copious amounts of information to review and use, to help others enrich their lives.  The staff wants you to succeed and will help you to understand the materials. It was so nice to be part of the 2014 2016 class.  I will look forward to helping others.  It is hard to believe the two year program is over, I have learned so much and look forward to my future.

Linda Miller | Class of 2016

David’s herbal studies program is a wealth of information. Becoming a certified herbalist is an invaluable addition to my nutrition practice

Leslie Weinman | Class of 2016

The measure of a school and a teacher is how well they prepare you for your profession. David Winston, in Japan, would be a “national treasure”. His broad base of multi-cultural herbal knowledge, and especially the traditional medicine, is unique. He is simply encyclopedic in his ability to access his years of learning and answer any question. His teaching method is infectious curiosity, well-organized units that build on each other, and that culminates in an excellent preparation for clinical practice: how to do effective case histories, how to put together effective and balanced herbal formulas, how to use nutrition / supplementation / mind & physical therapist and lifestyle changes to pull together an excellent Protocol for your client.

Serious, and jam-packed as each class is, you leave each class inspired and excited. And, David has an excellent sense of humor. I am constantly reminded of how David Winston is held up for special respect in the world of herbalists whenever I go to important herbal conferences. He is in constant demand as a regular guest lecturer at herb and naturopathic schools of higher learning here in the States and around the world.

I am a graduate of David’s school and graduate clinical course, and have my professional designation from the American Herbalists Guild. I have been in practice since 1996, and at age 70, in 2012, I am moving to Key West and closing my practice. David’s excellent school enabled me to help a lot of people along the way.
