Spearmint for Hormonal Health
More than a flavor. Spearmint is one of the most promising natural tools for managing excess androgens - and it's backed by real clinical evidence.

More Than a Flavor
Spearmint (Mentha spicata) is one of the world's most widely consumed herbs - found in everything from toothpaste to mojitos. But in the last two decades, clinical researchers have uncovered something far more significant than its refreshing taste.
Rich in rosmarinic acid, flavonoids, and essential oils (primarily carvone and limonene), spearmint has demonstrated anti-androgenic properties - the ability to reduce elevated androgen hormones like testosterone, DHEA, and androstenedione. For the millions of women dealing with PCOS and its symptoms, this is a game-changer.
Unlike pharmaceutical anti-androgens (which can have significant side effects), spearmint offers a gentler approach - working through natural mechanisms that the body can integrate over time.
The PCOS Connection
Polycystic Ovary Syndrome (PCOS) affects roughly 10% of women of reproductive age - making it one of the most common endocrine disorders worldwide. At its core, PCOS is often characterized by elevated androgens - hormones like testosterone that, in excess, drive many of the condition's most visible and distressing symptoms:
- •Hirsutism - unwanted facial and body hair growth
- •Hormonal acne - persistent breakouts along the jawline, chin, and cheeks
- •Hair thinning - androgenic alopecia affecting the crown and part line
- •Irregular cycles - anovulation driven by hormonal imbalance
Spearmint directly targets this androgen excess mechanism - which is why it's become one of the most talked-about natural approaches in the PCOS community.
What the Clinical Research Shows
Grant 2010 - The Landmark PCOS Trial
A 30-day randomized controlled trial with 42 women with PCOS found that spearmint tea consumed twice daily led to significant decreases in free and total testosterone levels. Participants also reported reduced self-assessed hirsutism.

This was the study that put spearmint on the map for hormonal health. A simple intervention - two cups of spearmint tea a day - produced statistically significant androgen reduction in just 30 days.
2024 - Larger-Scale Confirmation
A 12-week RCT with 150 participants (both PCOS and non-PCOS women) found that spearmint tea consumption reduced DHEA levels by 18% and androstenedione by 14%. Notably, the effects differed between PCOS and non-PCOS populations, suggesting spearmint may be most beneficial when androgen levels are already elevated.

This larger trial not only confirmed the anti-androgenic effect but added an important nuance: spearmint appears to specifically target excess androgens rather than suppressing healthy baseline levels. This selective action is exactly what makes it appealing as a daily wellness ingredient.
Earlier Findings & Animal Research
A 2007 study by Akdoğan demonstrated rapid reduction in free testosterone and increases in LH, FSH, and estradiol after just 5 days of spearmint tea. Animal research (Springer, 2020) showed that a spearmint + flaxseed combination improved endocrine profile and ovarian histomorphology - suggesting potential benefits at the tissue level, not just in blood markers.
Honest framing
The evidence is promising and growing, but long-term human trials beyond 12 weeks are still needed. Most studies use spearmint tea rather than standardized extracts, so precise dosing recommendations remain unclear. Spearmint is a supportive tool - not a replacement for medical management of PCOS or other hormonal conditions.
Beyond Hormones
Spearmint's benefits extend beyond androgen management. The herb is rich in antioxidants - rosmarinic acid is a particularly potent one - that help protect cells from oxidative stress. Its anti-inflammatory properties may support gut health and reduce systemic inflammation, which is often elevated in women with PCOS.
Traditional uses include digestive support (spearmint is cooling and soothing to the GI tract), nausea relief, headache management, and promoting a sense of calm. In Ayurveda, spearmint is considered Saumya (cooling) - counterbalancing the "heat" of stress, irritability, and PMS-related discomfort.
Why It's in Cycle Glow
Spearmint's anti-androgenic action complements shatavari's adaptogenic support and ginger's anti-inflammatory foundation. Together, the three botanicals in Cycle Glow address hormonal wellness from three complementary angles:
Shatavari
Stress adaptation
Spearmint
Androgen balance
Ginger
Inflammation reduction
No other grab-and-go beverage combines these three specific mechanisms. And because the research suggests spearmint works best with daily consistency, a sparkling drink you actually enjoy is a better vehicle for adherence than a capsule you forget in your cabinet.
Spearmint FAQ
How much spearmint do I need daily?
+
Clinical trials used spearmint tea twice daily (roughly equivalent to 2 cups or ~900mg of dried spearmint). Cycle Glow contains a formulated dose designed for daily consumption, balanced for both efficacy and taste. Consistency matters more than maximizing any single dose.
Is spearmint safe long-term?
+
Spearmint has centuries of safe use as a culinary herb and tea. Clinical trials up to 12 weeks reported no significant adverse effects. However, very long-term studies (years) in concentrated extract form haven't been conducted. As with any herbal ingredient, we recommend ongoing dialogue with your healthcare provider.
Does spearmint help with acne?
+
Hormonal acne is often driven by excess androgens. Since spearmint has been shown to reduce free testosterone and other androgens, it may help address one of the root causes of hormonal acne - from the inside out. Multiple clinical trials have noted improvements in self-reported skin outcomes, though spearmint alone isn't a substitute for a complete skincare approach.
Is spearmint in Cycle Glow the same as spearmint tea?
+
The active compounds are the same - rosmarinic acid, flavonoids, and volatile oils. Cycle Glow uses a formulated spearmint extract designed for consistent daily dosing, combined with shatavari and ginger for synergistic hormonal support. Think of it as spearmint tea's more intentional, more convenient cousin.
