The efficacy of Acorus calamus

Calamus is a commonly used traditional Chinese medicinal herb, primarily employed for clearing heat, promoting urination, and relieving pain. It has the effect of clearing heat and detoxifying, effectively eliminating internal heat toxins and alleviating symptoms caused by excessive heat, such as thirst, bad breath, runny nose, headache, and sore throat. It also possesses diuretic properties that improve urine flow, remove toxins and bacteria from the urinary tract, and regulate urine pH, thereby helping to treat urinary tract infections. Additionally, calamus has analgesic effects, which can alleviate conditions such as dysmenorrhea, lower back pain, and lumbar disc herniation, providing effective pain relief.
