Learn MoreI started this program as a beginner with little understanding of the human body and its processes. I also had a very basic grasp of medicinal herbs. I am finishing this course with a deep understanding of how herbs can support the body’s systems and I feel confident working with people in this manner. The course offers a wide range of knowledge and skills with highly skilled and trained teachers. It offers plenty of opportunity for practice and feedback. If you’re thinking about taking this course – do it! It is empowering and enlightening and you will not regret it!
