'Indian Viagra': Caterpillar-Killing Fungus Kira Jari Harvested For Sex And Sports

One man's invasive fungus is another man's sexy time medicine.

A rare fungus that kills caterpillars and then grows in their bodies is being used in some countries as a cash crop, a performance enhancing drug -- and even an aphrodisiac, according to BBC.

Know in north India as "kira jari" -- or Indian Viagra, to some -- the fungus has gained popularity not only for its effects, but because it brings in the dough. Just one dead caterpillar bearing the stuff can yield up to $3, or an entire day's pay for a manual laborer.

The fungus mummifies its victim that then grows out of its head, the Daily Bhaskar reported. It's rare because it can only be found at high altitudes in the Indian Himalayas after the snow melts in May or June.

Indians have used Kira jari as a physical stimulant in sports, while many in China use it as a physical stimulant between the sheets.

But before you go out in search of these love bugs, remember that they're legal to possess in India, but illegal to sell.

If you're confused about the kira jari, watch the video below. The phenomenon was given the Taiwanese video treatment, so it'll be even more confusing, but you'll have a laugh.
