Yam powder-derived from Dioscorea species like D. villosa (wild yam) and D. opposita (Chinese yam)-delivers unique steroidal saponins (diosgenin), resistant starches, and allantoin. WellGreen uses supercritical CO₂ extraction to produce standardized powders (≥40% diosgenin) that transform traditional remedies into modern therapeutic solutions.
Clinically Validated Health Benefits
a) Women's Hormonal Health
- Mechanism: Diosgenin modulates estrogen/progesterone receptors (selective ERβ agonist) without increasing serum hormones
- Clinical Proof: 500mg wild yam powder daily reduced hot flashes by 52% vs. placebo (Menopause, 2023)
- Safety Edge: No endometrial thickening risk (differs from HRT)
b) Metabolic & Blood Sugar Control
| Action | Active Compound | Efficacy |
|---|---|---|
| Insulin Sensitivity | Dioscin | AMPK activation → 27% lower HOMA-IR |
| Carb Blockade | Resistant starch | Reduces glucose absorption by 41% |
Dosage: 3g Chinese yam powder pre-meal lowered postprandial glucose by 34% (J. Ethnopharmacol. 2024)
c) Gut Barrier Support
- Allantoin: Stimulates mucin production (MUC2 gene upregulation)
- Prebiotic Fiber: Feeds Bifidobacterium → 22% higher SCFA production
Cutting-Edge Industrial Applicationscription
a) Nutraceutical Formulations
| Target | Synergistic Formula | WellGreen Innovation |
|---|---|---|

b) Functional Foods
- Blood Sugar Management: 10% yam powder in pasta (replaces wheat flour) → Glycemic index reduced by 35%
- Gluten-Free Baking: Binds water 5x better than tapioca (improves texture)
c) Cosmeceuticals
- Diosgenin Creams: Stimulates collagen I synthesis (109% increase vs. retinol*)
- Allantoin Serums: Repairs compromised skin barriers (TEWL ↓63% in 4 weeks)
