Five tenths of Panax Notoginseng, three tenths of Salvia Miltiorrhiza and two tenths of Ligusticum Chuanxiong are all drugs for promoting blood circulation and removing blood stasis, but their main function is Panax Notoginseng. Ligusticum Chuanxiong is a good medicine for treating headache, but it should be used with caution if it is prone to cerebral hemorrhage. In particular, it should be noted that Salvia miltiorrhiza (for oral administration) should be clear and clean, and the decoction pieces of this medicine pharmacy have many impurities and low quality. For reference.
