According to wikipedia (must be correct then):
Cow urine therapy is capable of curing several curable and allegedly incurable diseases and cow-based products have multi-purpose benefits.
India’s leading Hindu cultural group has developed Gau Jal or Cow Water at its research centre in the Indian holy city of Haridwar on the River Ganges, and hopes it will be marketed as a ‘healthy’ alternative to Coke and Pepsi.
I cant really see it catching on in the west. Although im currently sipping on a bottle of orange VitaminWater and wondering if it could taste much worse?!?
