Western Classification of the Materia Medica

The Traditional Western Materia Medica was classified in a very functional and logical way. The effects of Medicines like the effects within the body were termed ‘Faculties’ of which there are 4.

1. Primary Faculties: Temperature: Hot, Cold, Dry and Moist (see here)
2. Secondary Faculties: effects as a direct result of the Primary Faculties:
      Heat: opens, rarifies, attenuates, attracts
      Cold: thickens, congeals, stops, repels
      Dry: knits, hardens, dries, astringes
      Moist: softens, mollifies, moistens and lubricates
3. Tertiary Faculties: effects not related to the Primary Faculties and were sometimes caused ‘Hidden’ or ‘Occult’ Faculties. They are either found by experience or some special signature.
4. According to Part: Medicines were also classified according to Organ or Part.
