Advanced Comparative Materia Medica

with Paul Bergner, November 30 to December 1, 2019

Course Information

When the Materia Medica is studied in depth, with attention to the totality of humoral and energetic effects, clinical actions, clinical uses, and tissues affected, groups of herbs with similar actions and uses emerge as “affinity groups” of analogues. Herbs in each group may have small differentials between them, but for practical purposes they may often be combined for broader but still-focused physiological and humoral effects or substituted for each other in formula compounds. We will study in depth more than 70 herbs in 24 herbal affinity groups, emphasizing for each group constitutional indications, differentials between similar herbs, and ways to use that category therapeutically and in formulation. We will look at correlations between Western and Asian materia medica, some forgotten herbs that should be remembered, and traditional herbs which may be useful for emerging syndromes and conditions not typically seen in traditional literature.

Categories to be covered include the following:

  • Topical herbs with anti-inflammatory and wound healing effects
  • Topical antiseptics with immune strengthening effects
  • Topical antiseptics with strong mucous membrane effects
  • Drying mineral-rich herbs
  • Systemic demulcents
  • Bitter demulcents
  • Alterative immune-enhancers
  • Chamomile as a category of its own
  • The mints
  • The bitter mints
  • Antispasmodic herb differentials
  • The three cohoshes compared
  • Anti-inflammatory herbs hot in the third degree
  • Carminative relaxants for the system
  • Expectorant differentials
  • Tonic astringents to hepatic portal system
  • Herbs which can relax liver tension
  • Alterative differentials
  • Stimulating adaptogens
  • Immune enhancing adaptogens
  • Restorative adaptogens
  • Adaptogens for the dry patient
  • Warming herbs for the reproductive system
