Fringe Tree

Fringe tree, Chionanthus virginicus, is a small deciduous tree of the olive family (Oleaceae) native to the eastern United States; its bark and root bark are traditional botanical raw materials containing lignans and saponins. Nustras supplies fringe tree bark as dried cut bark, milled powder and standardised extract powder for the botanical supplement and herbal product trades.

It is formulated into herbal capsules and tablets, botanical blends, tinctures and liquid botanical preparations, and herbal teas, by supplement manufacturers and contract formulators.

The dried bark is a grey-brown to reddish-brown fibrous material with a bitter taste; the powder is light brown and the extract a brown powder. Identity is confirmed by macroscopic and microscopic examination or by HPTLC against a reference, with marker content standardised to specification. Heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies fringe tree bark 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. Fringe tree is a traditional North American botanical accepted in major supplement markets under market-specific conditions; buyers confirm the permitted plant part, level and claim for their application.
