1. Product Description & Key ParametersLeonurus Japonicus Extract (Yimucao Extract) is a natural botanical extract derived from the dried aerial parts of Leonurus japonicus Houtt., an annual or biennial herb belonging to the Lamiaceae family, commonly known as "Yimucao" in traditional Chinese medicine. It has a long history of application in traditional Chinese medicine for its effects of activating blood circulation and regulating menstruation, tonifying the uterus and relieving dysmenorrhea, clearing heat and detoxifying, and reducing swelling and promoting diuresis. The extract is produced through advanced water-ethanol mixed solvent extraction (ratio 60:40 v/v), purification, concentration and spray-drying processes, which effectively retain the plant's bioactive components. The final product is a yellowish-green to greenish-brown fine powder with a characteristic natural herbal odor, good flowability and no visible impurities, consistent with the typical appearance of Leonurus japonicus extract.Core Parameters:
