Wild Yam Extract
Snapshot
Wild Yam Extract is derived from the root of Dioscorea villosa, traditionally used to support hormonal balance, menopausal comfort, and digestive health through its saponin content.
What is Wild Yam Extract?
Wild Yam Extract is a concentrated preparation of the dried rhizome of Dioscorea villosa, rich in steroidal saponins—particularly diosgenin—which serve as precursors for endogenous hormone synthesis and exert anti-inflammatory effects.
Where It Comes From
Wild yam roots are harvested in late summer or autumn, cleaned, sliced, and extracted with ethanol or hydroalcoholic solvents; the concentrated tincture or powder is standardized to contain 10–20% diosgenin.
Key Nutrients & Compounds
Provides diosgenin and related glycosides (dioscin), along with polysaccharides and mucilage, which may influence steroidogenesis pathways and soothe gastrointestinal mucosa.
Health Benefits
Wild Yam Extract may support relief of menopausal symptoms (hot flashes, mood swings) by providing diosgenin precursors; promotes healthy digestive function by reducing inflammation; and supports joint comfort.
Recommended Dosage
Standardized extracts (10% diosgenin) are typically dosed at 300–600 mg daily, divided into two servings with meals; tinctures (1:5) at 2–4 mL, 1–3 times daily.
How to Use It
Take capsules or powder with water during meals; tinctures can be diluted in water or juice. Consistent use for at least 4–8 weeks is recommended to assess hormonal and digestive benefits.
Who Should Use It?
Adults seeking natural support for menopausal transition, hormonal balance, or mild gastrointestinal discomfort; those interested in phyto-support for joint health.
Possible Interactions or Cautions
May interact with hormone-modulating medications; avoid if pregnant or breastfeeding; discontinue if allergic reactions occur; consult a healthcare provider before use if on hormone therapy.
Final Thoughts
Wild Yam Extract offers a plant-based source of diosgenin for supporting hormonal and digestive health, though clinical evidence is limited and professional guidance is advised for hormone-related uses.
