See, I don't deny there is some wisdom in traditional medicines. I know Asprin originally was willow bark when someone found the active ingredient in it --salicylic acid if my memory serves me right. Even Chinese found a new drug for malaria in their herbs from traditional Chinese medicine and they found a way to synthesise it. If something exists in Cow-urine, it should be found and synthesized! But then this entire thing looks more like a conclusion assumed than derived.
The chain of thought seems like :
Milk is nutritious -> Cow is precious -> Cow is divine -> Even Cow's urine is good for you. We will figure out it is good for what later.
Cow urine contains nitrogen, sulphur, phosphate, sodium, manganese, iron, silicon, chlorine, magnesium, maleic, citric, tartaric and calcium salts, vitamin A, B, C, D, E, minerals, lactose, enzymes, creatinine, hormones and gold acids. Ingredients of cow urine are similar with human body. Hence consumption of cow urine is useful to maintain the balance of these substances and cures incurable diseases6 . Medicinal Properties of Cow urine has been granted by US, as Patents (No. 6,896,907 and 6,410,059); bioenhancer, antibiotic, antifungal, and anticancer agent properties are particularly mentioned in those patents. Cow urine increases potency of “Taxol” (paclitaxel) against MCF-7, a human breast cancer cell line, in in vitro assays (US Patent No. 6,410,059).
