Learn the Energy of Herbs and Illness in the Professional Herbalist Course

The Way of Herbs by Michael TierraThe Way of Chinese Herbs by Michael TierraThe Way of Ayurvedic Herbs by Michael Tierra

While Western herbal training tends to emphasize the allopathic use of herbs (“this herb is good for that”) along with their pharmacology and biochemistry, our Planetary Herbal approach teaches the energetic identification and application of herbs. 

Energetic herbalism recognizes the heating or cooling, strengthening or eliminating, rising or descending, taste, properties and so on of herbs and disease.

This system does not diagnose and prescribe but identifies patterns of illness based on specific energies and then chooses herbs and treatment strategies for those patterns.

The Planetary Herbalism energetic teachings of the East West Herb Courses are based on the oldest, living, extant herbal medicine systems of Traditional Chinese Medicine (TCM) and Traditional Ayurvedic Medicine (TAM), each of which have over 5000 years of experience and practice.

These energetic systems are only tools, yet they have proved to be the most effective, efficient, and alternative approaches to allopathic herbalism, medical diagnosis and treatment.

Learning Planetary Herbalism provides you with a rational treatment choice methodology. The East West Herb Courses also teach energetic diet and food therapy along with tools to tailor your own health-supportive diet along with preparations, remedies and other healing tools, techniques and therapies.

In fact, many students regain their own health, and/or help their family members and friends regain their health, just by studying and applying our course teachings.
