Sheep Sorrel

Sheep sorrel is the dried aerial part of Rumex acetosella, a low-growing perennial of the dock family (Polygonaceae) found across temperate regions of North America and Europe. Nustras supplies it as cut and sifted herb, fine powder and extract powder for the herbal tea and supplement trade. The leaf is naturally rich in oxalic acid, which gives it a tart taste, together with flavonoids and tannins.

Sheep sorrel is formulated into herbal tea blends and loose-leaf infusions, single-herb and combination capsules and tablets, liquid tinctures and glycerites, and the traditional multi-herb formulas in which it is a well-known component.

The material is a green to greyish-green cut herb or powder with a herbaceous odour and sour taste. Identity is confirmed by macroscopic and microscopic examination and thin-layer chromatography, and the extract is standardised to specification. Heavy-metal, pesticide-residue and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies sheep sorrel 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. Sheep sorrel is an accepted herbal ingredient in major supplement markets; buyers confirm the permitted plant part, preparation and claim for their application.
