Leonurus japonicus Granules are a traditional Chinese patent medicine, with Leonurus japonicus (Motherwort) as its primary active ingredient. Traditional Chinese herbal medicines are commonly used clinically for treating gynecological disorders, promoting blood circulation, and regulating menstruation.

Are Leonurus japonicus Granules Effective for Hypomenorrhea?
Taking Leonurus japonicus Granules during menstruation—particularly when menstrual bleeding is scanty—can be beneficial. First, Leonurus japonicus exerts pronounced effects in promoting blood circulation, resolving blood stasis, alleviating pain, and regulating menstruation. It effectively improves menstrual irregularities—including delayed cycles, hypomenorrhea, and prolonged spotting. However, for patients experiencing hypomenorrhea, it is advisable to undergo clinical evaluation first to identify the underlying cause before initiating targeted pharmacotherapy—this ensures optimal therapeutic outcomes. During this period, patients should prioritize keeping warm, especially avoiding abdominal exposure to cold, and consume iron- and blood-nourishing foods, which may further help improve menstrual flow.
