Sanskrit Verse
अनुपानं हितं स्निग्धं मारुते, पित्ते मधुरशिशिरं, कफे रूक्षोष्णम्।
— (Sushruta Samhita, Sutrasthana 46/465)
Explanation
Anupana is a ‘vehicle’ or medium that is taken along with or after a medicine or food. Its purpose is to enhance the absorption, effectiveness (Yogavahi), and delivery of the main substance to the target tissue. Common anupanas include warm water, honey, ghee, and milk.
Clinical Importance
The choice of Anupana is crucial for the efficacy of a formulation. For example, taking a Vata-pacifying herb with warm water or ghee enhances its action, while taking a Kapha-pacifying herb with honey increases its scraping (Lekhana) quality.
