Ayurvedic medicine and turmeric
So, the question is why has turmeric been such an effective Ayurvedic medicine if there are issues with its bioavailability. The answer is two-fold.
- It is a common cooking ingredient in Traditional Indian cuisine so it has preventive effects.
- Ayurvedic doctors and practitioners often prescribe turmeric and other Ayurvedic herbs and spices with an anupana e.g. milk decoction, honey etc. This method of administration assists the main ingredient (turmeric) to improve its antigenicity to the tissues (dhatus) and thus help it reach the deeper tissues achieving results which are congruent to the commercial herbal turmeric supplement. Ayurvedic practitioners will also successfully utilise turmeric as part of various formulations for arthritis pain treatment and other ailments.
