If you have PCOS, you have almost certainly landed on two names in your research: spearmint tea and spironolactone. Both are positioned as androgen-lowering options, both have real evidence behind them, and both come up constantly in conversations about managing excess testosterone, facial hair, acne, and irregular cycles. But the question of spearmint tea vs spironolactone for PCOS is not as simple as natural versus pharmaceutical. The right choice depends on your symptom severity, your health history, and how much change you actually need. Before diving in, if you want the full hormonal picture of PCOS, start with The Complete Guide to PCOS, which covers every driver from insulin resistance to adrenal androgens.

What Are Androgens and Why Do They Matter in PCOS?

Androgens are a group of hormones, including testosterone and DHEA-S, that are present in all women but are produced in excess in up to 80% of PCOS cases. Elevated androgens drive the most visible PCOS symptoms: acne along the jaw and chin, unwanted facial and body hair (hirsutism), scalp hair thinning, and disrupted ovulation.

In a healthy cycle, the ovaries produce small amounts of testosterone that contribute to libido, muscle tone, and energy. In PCOS, the signalling between the pituitary gland and the ovaries goes off-balance. LH surges too frequently, stimulating the ovaries to produce far more testosterone than needed. At the same time, insulin resistance (present in around 70% of people with PCOS) further drives androgen production by amplifying LH signalling and reducing sex hormone binding globulin (SHBG), which normally mops up free testosterone.

Lowering androgens is therefore central to managing PCOS. Both spearmint tea and spironolactone target this pathway, but they do so through very different mechanisms.

For more on how androgens interact with your cycle, see our deep-dive on Androgens and Your Cycle: The Hidden Driver.

How Does Spearmint Tea Lower Androgens?

Spearmint tea lowers androgens primarily by reducing free testosterone levels and increasing luteinising hormone (LH) sensitivity. Its active compounds appear to inhibit 5-alpha reductase, the enzyme that converts testosterone into its more potent form, dihydrotestosterone (DHT), making it a genuinely evidence-backed natural androgen-lowering option for PCOS.

The key clinical trial, published in Phytotherapy Research, found that women with PCOS who drank two cups of spearmint tea daily for 30 days showed a statistically significant reduction in free testosterone and a modest rise in LH and FSH compared with a chamomile tea control group. A longer five-week randomised controlled trial by Grant (2010) replicated the free testosterone reduction and noted improvements in self-reported hirsutism scores.

"The anti-androgenic properties of spearmint are modest but measurable. For women with mild-to-moderate hyperandrogenism, it is a reasonable adjunct, though it should not replace medical treatment in severe cases."

Dr. Jerilynn Prior, MD, FRCPC, Professor of Endocrinology, University of British Columbia

Spearmint also contains rosmarinic acid and flavonoids that have anti-inflammatory properties. Since PCOS is increasingly understood as a low-grade inflammatory condition, this secondary benefit matters. You can explore the inflammation angle further in our article on Inflammatory PCOS: What It Is and How to Treat It.

Critically, spearmint tea does not block androgen receptors. It reduces the amount of circulating androgens rather than preventing them from binding to target tissues, which is an important distinction when comparing it with spironolactone.

How Does Spironolactone Work for PCOS Androgens?

Spironolactone is a prescription aldosterone antagonist that was originally developed as a diuretic. At doses of 50 to 200mg daily, it blocks androgen receptors directly, preventing testosterone and DHT from binding to tissues in the skin and hair follicles. This makes it significantly more potent than spearmint tea at reducing the visible effects of excess androgens like hirsutism and acne.

Unlike spearmint tea, spironolactone does not substantially reduce total testosterone production. Instead, it competes with androgens at the receptor level, which is why it works even when androgen levels are only mildly elevated. This receptor-blocking action means results for skin and hair can be more pronounced and faster than diet or herbal interventions.

Spironolactone also has a mild anti-androgenic effect via inhibition of the same 5-alpha reductase enzyme that spearmint targets, giving it a dual mechanism. Because it is a diuretic, it can cause increased urination, low blood pressure on standing, and electrolyte shifts, particularly elevated potassium. It is contraindicated in pregnancy, so reliable contraception is required for anyone of reproductive age who is sexually active.

"Spironolactone remains one of our most effective tools for PCOS-related hirsutism and acne. The side effect profile is manageable for most patients, but it is not appropriate for everyone, and I always discuss lifestyle and nutritional strategies alongside it."

Dr. Ricardo Azziz, MD, MPH, MBA, Distinguished Professor, Augusta University, leading PCOS researcher

Spearmint Tea vs Spironolactone for PCOS: How Do the Results Compare?

Head-to-head, spironolactone produces faster, more significant reductions in PCOS androgen symptoms like hirsutism and acne than spearmint tea. Spearmint tea offers a gentler, side-effect-free reduction in free testosterone that suits women with mild symptoms or those seeking a natural alternative to spironolactone to complement other lifestyle interventions.

Here is how the two approaches stack up across key measures:

One area where spearmint may genuinely shine is in combination strategies. Many women use spearmint tea alongside inositol, anti-inflammatory eating, and blood sugar support to create a multi-pronged approach that does not require a prescription. If you are already exploring that route, our guide on Inositol vs Metformin for PCOS covers another key piece of the puzzle.

Who Is Spearmint Tea Best Suited For?

Spearmint tea is most appropriate for women with mild hyperandrogenism, those who prefer a natural alternative to spironolactone, women who are trying to conceive (for whom spironolactone is contraindicated), or those using it as a complementary strategy alongside other evidence-based PCOS interventions.

Good candidates for spearmint as a primary PCOS androgen-lowering strategy include:

It is worth noting that spearmint tea should not be used in large quantities during pregnancy, and standard advice is to limit it to one to two cups per day in all contexts. Very high doses have shown anti-androgenic effects in animal studies that could theoretically be problematic.

Who Is Spironolactone Best Suited For?

Spironolactone is best suited for women with moderate-to-severe PCOS androgen symptoms, particularly significant hirsutism, cystic hormonal acne, or scalp hair loss, where a stronger, faster-acting androgen-blocking approach is clinically warranted and where contraception is in place.

Strong candidates for spironolactone include:

Can You Use Both Spearmint Tea and Spironolactone Together?

Combining spearmint tea with spironolactone is generally considered safe, though there is no clinical trial data specifically studying the combination. Both reduce androgen activity through different mechanisms, so theoretically they could complement each other, but always inform your prescribing clinician about herbal supplements you are taking.

Some women transitioning off spironolactone choose to introduce spearmint tea, inositol, and dietary changes as a longer-term maintenance strategy once symptoms are well controlled. This step-down approach is worth discussing with your doctor rather than stopping spironolactone abruptly, as androgens can rebound when the medication is withdrawn.
