Can Leonurus japonicus (Yi Mu Cao) induce menstruation?
Menstrual irregularities caused by deficiency of qi and blood may be alleviated by taking Yi Mu Cao granules, which help regulate the nervous system. However, for menstrual delay attributable to other causes, using this herb solely to induce menstruation is not recommended. Other blood-activating medications—such as Xiao Yan Wan (Anti-inflammatory Pills) and Tian Xi Wan—may also promote menstruation. Given the close relationship between menstruation and female health, it is crucial to identify the underlying cause before initiating any treatment; blind use of medication to induce menstruation is inadvisable.

Numerous factors can cause menstrual delay in women. First, gynecological conditions—including pelvic inflammatory disease, premature ovarian failure, polycystic ovary syndrome (PCOS), and cervical hypertrophy—may impede the outflow of menstrual blood, resulting in delayed periods. Second, endocrine disorders are another major contributor: hormonal imbalances significantly disrupt ovarian hormone secretion, ultimately delaying menstruation. Third, excessive weight loss can also lead to menstrual delay. Since adequate nutrition is essential for maintaining regular menstruation, malnutrition resulting from extreme dieting may interfere with normal menstrual onset.

Additionally, other factors—such as general menstrual irregularity or adverse drug reactions—can also contribute to delayed menstruation. For postpartum women, however, consuming Yi Mu Cao in soups or congee may help resolve postpartum blood stasis. We hope this information proves helpful!
