Kudzu

Kudzu (Pueraria lobata, syn. Pueraria montana var. lobata) is a perennial climbing vine of the legume family native to East Asia, whose root (Radix Puerariae) is a traditional botanical raw material. Nustras supplies it as a dried root powder and as extract powder for the supplement and natural-products sector. The root is a source of isoflavones, chiefly puerarin, daidzin, daidzein and genistin, and of starch.

It is formulated into botanical and isoflavone supplements in capsule, tablet and powder form, traditional-formula herbal blends, herbal teas and functional beverages, food products as kudzu starch (kuzu), and cosmetic formulations.

The material is an off-white to light brown powder. Isoflavone (puerarin) content or extract ratio, particle size, loss on drying and ash are standardised to specification; identity is confirmed by botanical identification and HPLC fingerprint (puerarin reference standard), and heavy-metal, pesticide-residue and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies kudzu 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. Kudzu root is an accepted botanical ingredient in major food and supplement markets; buyers confirm the permitted plant part, level and claim for their application.
