Tea Extracts & Supplements
Certain teas are sometimes discussed as “natural DHT blockers” because some of their plant compounds show anti-androgen activity in limited studies or laboratory models. Examples commonly cited include spearmint tea, which has small human trials showing reductions in free and/or total testosterone in women (often in PCOS or hirsutism contexts), and peppermint/spearmint teas, which lowered testosterone in animal studies (with spearmint appearing stronger). Green tea contains catechins such as EGCG that can inhibit 5-alpha-reductase in cell-free or in-vitro experiments, though whether this meaningfully lowers DHT in humans at typical intake levels remains uncertain. Black tea theaflavins have been reported to suppress androgen-related signaling (including androgen receptor and 5-alpha-reductase activity) in prostate cell research. Licorice root tea is one of the more clearly anti-androgenic herbal teas in humans, with clinical studies showing reduced serum testosterone, likely via effects on steroidogenic enzymes.
An important caveat is that much of this evidence is small-scale, population-specific (often female/PCOS), or based on animal or in-vitro models, and any “DHT-blocking” effect from tea is generally considered mild and inconsistentcompared with medications. For other teas (e.g., white tea, rooibos), evidence for androgen or DHT effects is more limited or indirect, and claims should be framed cautiously.

How to Interpret This Page
This page summarizes anecdotal reports and community observations, not medical evidence. “Risk” here refers to how frequently severe or prolonged symptom worsening is reported, not to proven causation or population-wide probability. Individual responses vary widely, and absence of issues in some users does not rule out significant reactions in others.
Risk Signal Based on User Reports
Reports of Mostly Transient Flares (for PFS/PSSD/PAS):
Among individuals who already have PFS/PSSD/PAS, certain teas—particularly those with clearer anti-androgen signals (such as licorice root and spearmint)—are occasionally mentioned in community reports as preceding symptom flares. These are more commonly described as temporary worsening that improves after stopping rather than permanent baseline changes. Reactions appear to vary by tea type, concentration (tea vs extract), frequency, and individual sensitivity.
For individuals without these conditions, these teas are widely consumed and generally well tolerated. Given the uncertainty and variability described in anecdotes, some people with PFS/PSSD/PAS choose to limit intake of more strongly anti-androgenic teas, avoid concentrated extracts, or test cautiously (one variable at a time), especially during stabilization.
Evidence basis: Small human studies, animal and in-vitro research; anecdotal reports (online forums, self-reports); no controlled studies examining PFS/PSSD/PAS-specific outcomes for tea consumption.
