Yes, spearmint tea is a powerful, science-backed ally for reducing the facial hair growth that often comes with PCOS. A significant clinical study involving 150 participants confirmed that drinking this herbal tea twice daily leads to a measurable drop in the hormones that trigger unwanted hair, specifically lowering testosterone levels by 15% and DHEA by 18%.1
Will this hair ever stop growing on my chin?
Hirsutism in PCOS is driven by hyperandrogenism — elevated androgen levels that signal hair follicles to produce thick, dark hair on the face, neck, and chest. The American Society for Reproductive Medicine classifies dietary and lifestyle interventions as first-line management for PCOS, alongside pharmacological options.
How does a simple tea actually change my hormones?
Spearmint acts as a potent “anti-androgen.” It works behind the scenes to dampen the production of the specific hormones that tell hair follicles to overproduce.
In a landmark 12-week study, researchers monitored “serum androgen profiles”—which you can think of as hormone snapshots—to prove the tea was doing the heavy lifting.1 The results highlighted a “triple threat” reduction in the three markers most responsible for PCOS hair growth:
- Testosterone: 15% reduction
- DHEA: 18% reduction
- Androstenedione: 14% reduction
By lowering this trio, the tea helps move your system back into a state of hormonal harmony, addressing the root cause of the hair growth rather than just the surface symptoms.
But how much do I have to drink to see a real difference?
- Dose: 2 cups per day (approximately 250 ml per cup, standard herbal teabag or loose leaf)
- Consistency: Drink it daily.
- Timeline: While one study showed hormone levels beginning to shift in just 30 days2, another study suggests that a full 12 weeks of consistency is required for the deep “hormonal remodeling” that leads to a significant change in actual hair growth patterns.1
Are there any side effects I should know about?
A meta-analysis of herbal tea consumption in PCOS found no significant adverse reactions versus placebo.3 Spearmint tea is well-tolerated by the majority of users.
Mild side effects reported in a related herbal tea study:
- Mild bloating or nausea — typically transient, resolving within the first 1–2 weeks
- Increased urination — attributable to additional fluid intake (500 ml/day), not a pharmacological effect
Interaction note: spearmint tea is not a replacement for prescribed PCOS medications. If you are on Metformin, combined oral contraceptives, or anti-androgens (spironolactone, cyproterone acetate), inform your prescriber before adding any herbal supplement to your routine.
Should I be drinking green tea instead?
Both teas have clinical evidence in PCOS, but they act on different pathways. They are not interchangeable — and for women with both hirsutism and metabolic symptoms, they are additive:
| Spearmint Tea: Best For… | Green Tea: Best For… |
| Reducing facial hair growth | Support for weight loss (WMD -2.86kg) |
| Lowering free testosterone levels | Managing Fasting Blood Glucose (FBG) |
| Balancing DHEA and Androstenedione | Improving Fasting Insulin (FINS) |
For hirsutism specifically, spearmint is the evidence-supported choice. Green tea provides no meaningful anti-androgenic effect.
What if I’m already taking meds like Metformin?
Think of spearmint tea as a “complementary approach”—it’s a helpful teammate for your existing treatment plan, not a replacement.
In fact, meta-analysis data shows that tea consumption can help with the metabolic side of PCOS that Metformin also targets, such as supporting weight loss (showing an average reduction of 2.71kg).3 This synergy can be very beneficial for your overall progress. As always, keep your doctor in the loop about any new herbs you add to your daily routine.
The Grocery Swap List
Beyond your tea ritual, we can further support clear skin and balanced levels by addressing environmental triggers like fried foods and refined carbohydrates.
| Swap This (Hormone Spikers) | For This (Hormone Helpers) |
| Sugary drinks and sodas | Spearmint tea (2 cups/day to lower androgens) |
| White bread, pastries, and pasta | Cinnamon (to improve insulin action) |
| Processed meats (sausages, hot dogs) | Flaxseed (30g/day to reduce testosterone) |
| Fried foods and sweetened yogurt | Green tea (to boost metabolic health) |
Implementation Checklist
- Start the protocol: 2 cups of spearmint tea daily — set a consistent time (e.g. morning and evening) to build the habit
- Set a 12-week review date: photograph or track hair growth pattern at baseline and at week 12 to assess follicle response
- Remove the top insulin driver: replace one sugary drink per day with spearmint tea — this addresses both androgen and insulin pathways simultaneously
- Add flaxseed if tolerated: 30 g/day; lignans in flaxseed reduce free testosterone by binding sex hormone-binding globulin
- Inform your prescriber: if you are on PCOS medication, flag the addition of spearmint tea at your next appointment
- Consider green tea addition: if metabolic symptoms (weight gain, elevated fasting glucose) are also present, green tea addresses the metabolic axis spearmint does not
