Planetary Herbology, Dr. Michael Tierra's unique, global approach to botanical medicine, unites a solid study of herbs, scientific research, medicine-making and diagnostic systems from all over the world.

Planetary Herbology brings together the 3 great systems of herbal healing –
  1. Western Herbal Medicine (WHM)
  2. Traditional Chinese Medicine (TCM) and
  3. East Indian Traditional Ayurvedic Medicine (TAM)

While we use and teach these three modalities primarily, we do not use them exclusively.

Isn't one of these systems enough?

Today, where ethnic and cultural boundaries are increasingly blurred and the international marketplace is rapidly expanding, students of herbal medicine are exposed to a wide variety of herbs from all over the world. Each herbal tradition's own materia medica (catalogue of plants used for medicine) has a unique relevance and value that another tradition may lack.

A solid knowledge of the uses of exotic as well as backyard herbs endows the planetary herbologist with a powerful advantage over those who only use plants from a limited geographic region.

In addition to the East-West materia medica, Planetary Herbology teaches diagnostic methodology from the three systems.

But even if one were to memorize the properties of hundreds of worldwide herbs, the ability to use them safely and effectively would be severely limited unless one also employed an assessment (diagnosis) methodology appropriate to the use of herbs. For this methodology, the eastern traditions of Chinese and Ayurvedic medicine offer us elegant and sophisticated systems that correlate the energies and properties of plants to specific differential diagnostic signs and symptoms, thereby allowing the practitioner to select the healing plants best suited to each individual case. These diagnostic systems may be used with any collection of herbs from any locality.

Using these systems, along with long-lost traditions from western herbal medicine, the East West Herb Course offers a comprehensive and truly planetary education in both materia medica and assessment.

In the 21st century, ease of travel and communication brings the remotest corners of the earth into our homes and herbal pharmacies! With that in mind, the true planetary herbologist is trained to be able to select and prepare the best plants at hand to heal themselves and others, both at home and abroad.

Of the many herbal training programs I have seen, I consider the East West Herb Course to be one of the best introductions to the world of clinical herbal medicine currently available. It provides a detailed introduction to the broad world of Western and traditional Chinese and Ayurvedic herbalism, unlike most schools which only focus on one discipline. It is also one of the most innovative programs that combines distance learning with in-person study of multiple herbalists, and for those who desire it, a clinical mentorship program. I would recommend it to any serious herbal student who seeks a distance learning model.'
