Panchgavya and cow products: A trail for the holy grail.

For millennia, cow has been central to Indian economy, life and culture. There are innumerable references-Vedic and subsequent to the sacred significance of cow. The benefits of cow have been described at length in relation to agriculture, environment, health, economy and spiritual progress. However, the socio-political issues surrounding cow as a sacred animal have raised acrimonious debates. In Ayurveda also, there is a long tradition of using cow products for positive health, pharmaceutical processes and in therapeutics. There have been quite a few studies on the activity, efficacy, safety and acceptability of Panchagavya and other cow products. Paradoxically, many cow products available in the market for human consumption require improved standardization and proper regulation. Integration of cowpathy (Govaidyak) in traditional Indian systems of medicine has been natural, based on their common dravyagunavigyan. But if its integration with conventional medicine is contemplated, we will need better understanding of the ingredients of cow products, their pharmacokinetics, pharmacodynamics and therapeutic ratio. A rational beginning can be made by data collection of experiential and anecdotal responses. A meticulous analysis of database of panchgavya and other cow products should look for temporal relationships, biological plausibility and translational potential before embarking on state-of-the-art experimental and clinical studies for selected indications.
