Yunnan Baiyao is useful in the treatment of sciatica. These drugs are good for treating sciatica caused by fresh trauma or old trauma, as they mainly help to activate blood circulation and eliminate blood stasis and reduce swelling and pain. In clinical practice, the patient must be fully diagnosed and treated to confirm the existence of the appropriate indications before using these drugs. For example, the doctor will look, smell, ask questions and cut the patient, and ask about the medical history and clinical symptoms, through this series of ways to determine the existence of local qi stagnation and blood stasis, and only then use this drug treatment. The effect of using such drugs may not be very good, so it is recommended that if you want to use Chinese medicine after the onset of the disease, you must ask a qualified Chinese medicine practitioner to identify and treat the disease before using it, and do not buy it on your own.
