Wild yam (Dioscorea villosa)
Persistently misrepresented as a 'natural progesterone source', wild yam diosgenin is not converted to progesterone in the body. Honest framing matters here.
Why
Wild yam (Dioscorea villosa) is one of the most-misrepresented herbs in the supplement industry. The popular claim, that wild yam provides natural progesterone, is biochemically false. Diosgenin from wild yam is the laboratory starting material for industrial synthesis of progesterone, but humans do not have the enzymes to convert diosgenin to progesterone in vivo. The Komesaroff 2001 RCT confirmed no effect on menopausal symptoms. Inclusion here is for honest reference and myth-correction.
How it works
Diosgenin is a plant steroid saponin used industrially as a starting material for steroid drug synthesis (via multi-step chemical processes). In vivo, humans do not convert diosgenin to progesterone, DHEA, or any other steroid hormone. Some traditional use for muscle cramps and mild antispasmodic effect is documented.
Expected onset · Not applicable, the proposed mechanism is not biochemically valid
How to take
Dosage
If used traditionally: dried root 1–3 g as decoction. As a hormone substitute: there is no biologically valid dosage, the conversion does not occur.
Timing
Not relevant for the misrepresented hormone-substitute use
On the label
Wild yam does not produce progesterone in the human body. For perimenopausal hormonal support, see physician-supervised options or evidence-anchored botanicals like black cohosh and vitex.
Ideal for
Educational reference, addressing the persistent 'natural progesterone' myth. Not recommended as a hormone-substitute.
Safety
Evidence
Komesaroff 2001 Climacteric placebo-controlled RCT (n=23): wild yam extract had no effect on menopausal symptoms, lipid profile, or sex hormone levels. The popular 'natural progesterone' claim is biochemically invalid, humans do not synthesise progesterone from diosgenin.
The marketed indication (natural progesterone source) is biochemically invalid, human enzymatic machinery does not convert diosgenin to progesterone in vivo. This is the rare entry where honest framing means active myth-correction.
