• Indications: This product is available in the British Pharmacopoeia (2017) and the European Pharmacopoeia (9.0th ed.). Monomeric compounds are currently used clinically. In clinical practice, hypericin is the main active ingredient of proprietary Chinese medicines, such as Acanthopanax capsules, of which Acanthopanax stem and leaf extract are the raw materials for the preparation. Xin’an capsules, prepared with hawthorn leaf extract, are rich in flavonoids, in which hyperoside, a kind of flavonoid, is one of the main components. Qi yue lipid-lowering tablets are prepared from the effective parts of Chinese medicinal herbs such as hawthorn (Nucleation) and Astragalus membranaceus. Flavonoid is one of the main active ingredients in hawthorn, in which hyperoside content is higher. Xinxuening tablets, containing ursolic acid, vitexin rhamnoside, hyperoside, citric acid, and others, is a preparation made from hawthorn and pueraria and other traditional Chinese medicines, in which hawthorn enhances the actions of the medicine. Clinical indications of Xinxuening tablets are coronary heart disease, angina pectoris, chest tightness, palpitations, high blood pressure, arrhythmia, hyperlipidemia, and mental depression.
