Sanskrit Verse
योगवाहि परं मधु।
— (Charaka Samhita, Sutrasthana 27/243)
Explanation
Yogavahi is the catalytic or synergistic property of a substance. A Yogavahi substance, when combined with another herb, carries and enhances the properties of that herb without losing its own properties. Honey (Madhu) is considered the best Yogavahi. Ghee and mercury are other examples.
Clinical Importance
This property is extensively used in formulating medicines. Honey is used as an Anupana (vehicle) for Kapha-pacifying herbs because it helps scrape the channels while delivering the herb’s action more effectively.
