Sanlangcao and Xiangshuizi are two different kinds of traditional Chinese medicines, which are different in medicinal parts, efficacy and main treatment. Sanlengcao is the stem and leaves of Salvia divinorum, which has the functions of promoting the flow of qi, dispelling wind and relieving itching (relieving itching by dispelling the wind that invades the surface of the muscle), and relieving phlegm, and can be used for the treatment of chest congestion and itching of the skin. It can be used to treat irregular menstruation, menstrual pain and amenorrhea caused by liver depression and qi stagnation, pain in the chest and ribs, and distension and pain in the epigastrium (abdomen). Although Sanlangzhao and Xiangshuizi come from the same plant, but the medicinal parts are different, its efficacy, the main treatment is also different. The medication should be taken under the guidance of a medical professional, and should not be used on its own to avoid adverse effects. If you feel unwell, please seek medical advice.
