Shangri-La abounds in various herbs, such as saffron and angelica. Saffron is said to have the ability to promote blood circulation in order to remove blood stasis and beautify the skin; angelica is held in high regard for its curative effect on irregular menstruation, chronic pelvic inflammatory disease, and dysfunctional uterine bleeding and blood deficiency. The unique climate of the Shangri-La plateau is very suitable of the growth of Chinese caterpillar fungus "Dongchong-Xiacao in Chinese£", a combination of fungus and dead caterpillar. It's a valuable medicine which is thought to improve human immunity. Moth larva is inflected by the fungus. The fungus absorbs its nutrition from the larva and grows out from the caterpillar's head.
