Export of Cultivated Picrorhiza kurrooa is Profitable but Requires Rigour

Picrorhiza kurrooa Royle ex Benth and P. scrophulariiflora Pennel are the two species of Picrorhiza growing in the Indian Himalayan Region. P. kurrooa is confined to the western Himalaya while P. scrophulariiflora occurs in the eastern Himalayan region and parts of Tibet. Recently, P. tungnathii Pusalkar has been described as a separate species from its related species P. kurrooa.
