FOCUS ON YOUR CLASSICAL TEXTS – Part III

Literature of Ayurveda – Laghutrayi (Subordinate trio)

The  compendia  after  the  period  of  Vagbhata reflect  further  developments  in contemporary  fields  of  science  and  incorporation  of  more  drugs  in  therapeutics. Madhava nidana, Chikitsa sara, Bhaishajya-ratnavali, Bhavaprakasha, Sharangadhara Samhita, Rasaratna samuccaya, and Yoga ratnakara are few examples of the compliation of literature of the ancient and a relatively recent period.  Also, there are 12 nighantus (Pharmacopoeias), which are a source of nomenclature and properties of different drugs.

The following three compendia are collectively known as laghutrayi (Subordinate / Smaller trio)

  1. Madhava Nidana
  2. Shrangadhara Samhita
  3. Bhavaprakasha
  1. Madhava Nidana

Madhavacharya (12th century) wrote Madhava Nidana which contains 69 chapters exclusively on the diagnosis of the diseases (Nidana).
