Three species of Lethariella are used by ethnic peoples of Yunnan Province (China) as a component of purported health-promoting tea: Lethariella cashmeriana, L.sernanderi, and L.sinensis. Species of Lethariella found in the Himalayas are also used as a component of Tibetan incense because of their fragrance, and are sold commercially in China.
