Rating (out of 5): 2

Maca (Lepidium meyenii) has a long history of use in traditional medicine, particularly in the Andean regions of Peru, where it has been consumed for its reputed effects on energy, fertility, and hormonal balance. Its use for supporting or alleviating symptoms of premenstrual syndrome (PMS) is primarily rooted in this tradition. Women in these regions have historically used maca as a food and natural remedy to help manage menstrual irregularities, fatigue, and mood swings associated with hormonal fluctuations. Traditional beliefs suggest that maca's adaptogenic properties may help support the endocrine system and overall hormonal health, which could theoretically ease PMS symptoms such as irritability, bloating, and cramps.

Scientific evidence to support maca's effectiveness for PMS is limited, with only a small number of preliminary human studies and animal research available. Some studies have shown that maca may have a balancing effect on sex hormones and may improve mood and symptoms like anxiety or depression, which are sometimes associated with PMS. However, these studies often have small sample sizes, lack placebo controls, or focus on menopausal rather than premenstrual symptoms. Thus, while traditional use is strong, high-quality clinical evidence remains insufficient, and more rigorous research is needed to confirm maca's benefits for PMS. Overall, its use for PMS is justified mainly by tradition rather than science.
