The leaves mentioned here are peppermint leaves. These leaves are commonly used in beverage preparation. A study by community nutritionist Dr. Emma Derbyshire (a member of the Tea Advisory Panel – TAP) found that peppermint tea helps balance female hormones. The peppermint tea used in the study was made from Mentha spicata leaves. This type of peppermint has a mildly sweet flavor and provides a refreshing sensation when consumed.
Peppermint tea contains compounds such as menthol, rosmarinic acid, and flavonoids (including luteolin). These compounds offer benefits such as protecting the body from harmful agents, reducing inflammation, and providing antibacterial effects.
Additionally, peppermint is known for its unique aroma and flavor. The compounds found in peppermint have been shown to improve health, aid digestion, reduce nausea, and alleviate stress.

Furthermore, peppermint tea has been found to have anti-androgen effects. This means that it can reduce the levels of androgens, male hormones such as testosterone, in the body. For women, elevated androgen levels can lead to issues such as excessive facial hair growth. This condition is commonly associated with polycystic ovary syndrome.
Several studies have explored the potential of using peppermint leaves to help lower testosterone levels in women, thereby reducing the growth of unwanted facial hair.
In Dr. Derbyshire’s study, women with polycystic ovary syndrome and those with idiopathic hirsutism (excessive hair growth) participated in a five-day experiment during the follicular or first half of their menstrual cycle. They consumed 250ml of peppermint tea, twice a day.
After the five-day period, the researchers found a significant decrease in testosterone levels among the participants. Lowered testosterone can reduce hair follicle stimulation and, consequently, decrease facial hair growth.
Dr. Derbyshire explained that peppermint can influence hormones, particularly testosterone, making this herb a popular choice for managing polycystic ovary syndrome, a condition often associated with hormonal imbalances in women.
Additionally, the menthol and flavonoid compounds found in peppermint are believed to have anti-androgen properties. Specifically, research indicates that menthol inhibits testosterone production. This is a crucial factor in maintaining hormonal balance in both men and women.
In the female body, reducing testosterone levels can promote a more balanced ratio of estrogen and progesterone. This balance is essential for regulating the menstrual cycle and overall health, particularly reproductive health.
Peppermint tea helps alleviate symptoms such as excessive facial hair growth, irregular periods, and acne in those with polycystic ovary syndrome. It also provides a soothing effect, contributing to improved mental well-being.
Dr. Derbyshire’s study further revealed that consuming 1-2 cups of peppermint tea daily can positively impact cardiovascular health, digestion, brain health, sleep quality, and joint pain.
