Product Introduction

Wild Yam Root Extract is sourced from Dioscoreaspecies rhizomes, standardized for diosgenin content. Our wild yam extract portfolio serves two markets: high-diosgenin grades (16%/20%) for semi-synthetic steroid precursors, and 6% standardized extracts for nutraceutical formulations. Non-standardized wild yam powder is offered for whole-herb applications.
