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.
