A parasitic caterpillar fungus that grows in the Himalayas has many names, according to Scientific American -- yarsagumba, yarchagumba, yartsa gunba, yatsa gunbu. But we are only going to remember one name: Himalayan Viagra.
This fungus, which leeches off of Tibetan ghost moth larvae, is said to get the fellas going when boiled and consumed in tea or soup. Oh, it also cures cancer and fights fatigue. Miracle drug! (Scientific American -- always with the science! -- notes, "These medical claims have not been borne out scientifically.")
As a result of its awesome properties of making everything sexy and cancer-free and sexy, this stuff is almost worth its weight in gold. (The price per gram puts its worth between silver and gold, Agence France Presse says.) And there's a global market for it worth between $5 billion and $11 billion.
