Congmun root boiled in water has the effect of dispersing blood stasis, facilitating urination, dispelling wind-dampness and eliminating swelling and poison, and is often used in wind-heat colds, coughs and wind-dampness paralysis. However, it should be noted that the effect of a single traditional Chinese medicine is weak, so it can be used together with other medicines under the guidance of traditional Chinese medicine to achieve the best therapeutic effect. Congmunia root is an expectorant of wind-dampness, with pungent and bitter flavor, flat in nature, and belongs to the liver, spleen and kidney meridians. It has the efficacy of dispelling wind-dampness, promoting blood circulation and circulation of menstruation, detoxifying and dispersing toxins and nodules, and is used in treating wind-heat colds, coughs, rheumatism and paralysis, lumbar and knee pain, gonorrhea, dropsy, jaundice, and so on. Pregnant women should not use aralia root in water. If necessary, please use under the guidance of a professional Chinese medicine practitioner.
