Picrorhiza Kurroa

Picrorhiza kurroa, known as kutki, is a small perennial herb of the Himalayan region whose root and rhizome are the parts used in commerce. Nustras supplies it as a dried root powder and as a root extract, for use as a botanical ingredient in Ayurvedic and herbal formulations. The root contains iridoid glycosides, principally picroside I and picroside II.

Picrorhiza root powder and extract are formulated into herbal supplements in capsule, tablet and powder form, into Ayurvedic and multi-botanical blends, and into liquid herbal preparations.

The root powder is a greyish-brown powder; the extract is a brown powder standardised to total picroside content to specification. Identity is confirmed by thin-layer chromatography against a picrorhiza reference, picroside content is determined by HPLC, and loss on drying, ash, heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies Picrorhiza kurroa root powder and extract in bulk commercial quantities, in food-grade bags and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Picrorhiza is an accepted herbal ingredient in several supplement markets; buyers confirm the permitted species, plant part and claim for their application.
