Panchagavya

(“five [products of the] cow”) A mixture
of cow’s milk, curds, clarified butter
(ghee), urine, and dung. Since each of
these products comes from the sacred
cow, it is considered a ritually purifying
substance. Panchagavya is drunk for
purification during rituals of expiation
(prayashchitta), and it can also be used
in other rituals used to purify people,
objects, and places.
