Guava leaves are commonly utilized locally to treat various issues, including menstrual cramps, lack of ovulation, and fertility problems. Many people using guava leaf extract seem to achieve their desired results. However, the question remains: how reliable and safe is the use of guava leaves for menstrual issues?

Studies comparing guava leaf and ibuprofen for period pain found guava leaves to be more effective in reducing menstrual pain. They also help improve blood flow and prevent clot formation during menstruation. Guava leaf tea is believed to reduce uterine contractions, which are responsible for painful periods.

Guava leaves also help prevent clot formation during menstruation. The tea, containing ferulic acid, gallic acid, quercetin, and active polyphenols, has been shown to have an anticoagulant effect against methylglyoxal- induced loss of antithrombin III activity.

Regular consumption of guava leaf for menstrual regulation can lead to more regular ovulation. Ovulation is the most fertile period of the month, characterized by discharge resembling the white part of an egg, which is stretchy and does not break.

People who misuse herbs by consuming an overdose should avoid guava leaves. Guava leaves are high in steroids, and excessive and frequent use can lead to steroid accumulation in the body, potentially disrupting the menstrual cycle for those allergic to steroid compounds. Overconsumption can cause periods to stop or become scanty instead of regulating them.
