Traditional uses
left, Snow lotus fruits selling in Chiang Rai, Thailand ''Costi amari radix'' or costus root was an important item of Roman trade with India, and is believed to have been the dried root of '' Saussurea lappa''. Several varieties of snow lotus are used in traditional Tibetan medicine. ''Saussurea lappa'' is used a component of the traditional Tibetan medicine Padma 28. Research conducted on the Himalayan medicinal plants by C.P. Kala reveals that the practitioners of Tibetan medicine living in the Pin Valley of Himachal Pradesh use its root for curing dysentery and ulcer. ''

As the slow-growing wild plant is endangered by collections, a substitute grown in tissue culture has been suggested, which is mostly equivalent. Generally the analgesic and antiinflammatory effects of the plant are much inferior to those of indometacin.
