Alder Bark

Alder bark is the dried bark of the alder tree, principally Alnus glutinosa, the European alder, and Alnus rubra, the red alder, supplied by Nustras as a cut-and-sifted botanical and as a powder for herbal and traditional-medicine formulations. It has a long history of use in European and Indigenous herbal traditions for its astringent, anti-inflammatory and antiseptic character.

It is used in herbal teas and decoctions, in tinctures and extracts, and as a botanical raw material in traditional topical and oral formulations. The bark is rich in tannins and related polyphenols, which account for its astringent profile.

The material is supplied from Alnus glutinosa or Alnus rubra, with the species specified to order, using the bark as the plant part, in cut-and-sifted or powder form, as a reddish-brown material. Identity is confirmed by organoleptic examination and TLC, and heavy-metal, pesticide and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies alder bark in bulk commercial quantities, in food-grade bags, cartons or fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Alder bark is used as a traditional herbal ingredient; buyers confirm the accepted botanical name, plant part and any claim against the applicable NNHPD resources and dietary-ingredient status for their market.
