Centella asiatica does not usually cure lumbar protrusion (herniated lumbar disc). Xianhe Cao is the dried above-ground part of the genus Longbudao in the family Rosaceae. It has the effects of astringency and hemostasis (treating bleeding disorders with drugs that have astringent effects), stopping malaria, stopping dysentery, detoxifying, and tonifying the deficiency. It is used for hemoptysis, vomiting blood, bleeding (excessive menstrual flow or dripping), malaria, dysentery, carbuncle sores and poisons, vaginal itching, and labor injuries. From the efficacy and action of Xianhe Cao, there is no treatment for lumbar disc herniation. If you need to treat a herniated disc, you should consult a hospital in time to standardize the treatment under the guidance of a doctor. If you need to use Xianhecao, it is recommended to use it under the guidance of a professional Chinese medicine practitioner, and individuals should not use it blindly, so as not to cause adverse consequences.
