Can motherwort be taken during menstruation?

Irregular menstruation can be treated with Leonurus japonicus (Yi Mu Cao), a traditional Chinese herbal medicine known for its properties of promoting blood circulation, regulating menstruation, inducing diuresis and reducing edema, and clearing heat and detoxifying. Patients with irregular menstruation may take it more frequently.

Can Yi Mu Cao be taken during menstruation?

Yes, Yi Mu Cao can be taken during menstruation—particularly starting on the first day of menses and continuing until menstruation ends. Yi Mu Cao enhances uterine contractions; when effective, it promotes stronger, more coordinated uterine contractions, thereby facilitating smoother menstrual flow. Consequently, Yi Mu Cao is especially suitable for patients experiencing heavy menstrual bleeding (menorrhagia), prolonged menstrual periods (menometrorrhagia), or dysmenorrhea. Menorrhagia is defined as menstrual blood loss exceeding three standard sanitary pads per day, while prolonged menstruation refers to a period lasting longer than one week. For women suffering from dysmenorrhea, adding Yi Mu Cao may help alleviate pain, reduce menstrual flow, and promote a smoother, more comfortable menstrual process.

During menstruation, avoid spicy, raw, and cold foods. Some women experience reduced appetite during their period and may turn to pungent or stimulating foods to enhance taste perception. Others may continue consuming chili-containing dishes or cold foods such as ice cream during their menstrual cycle. These foods can stimulate the uterus in various ways, potentially leading to increased menstrual flow, prolonged periods, impaired menstrual discharge, and worsening dysmenorrhea.
