Root of the High Himalayas

Saussurea costus is a striking high-altitude plant growing on the moist slopes of the Himalayas at 8,000-12,000 feet in Kashmir, Himachal Pradesh and Lahaul-Spiti. Its roots have a long history in traditional medicine and perfumery.

Because of over-collection, the species is protected under CITES, so it must be sourced under regulated, sustainable conditions.
