Trigeminal neuralgia belongs to the category of headache and facial pain in Chinese medicine. Paeonia lactiflora and licorice soup does not generally treat trigeminal neuralgia, but it has the effect of slowing down and relieving pain (relieving the symptoms of pain that is more urgent), which can alleviate the symptoms of pain to some extent. 1. In modern clinical research, Paeonia lactiflora and Glycyrrhiza glabra soup is now used for gastrocnemius muscle spasm (commonly known as calf cramp) caused by blood deficiency and fluid injury, stomach spasm, gastroduodenal ulcer, cervical spondylosis and other acute diseases of contracture of the meridians and veins caused by yin deficiency and blood loss. 2. The causes of trigeminal neuralgia are primary and secondary. The common cause of primary trigeminal neuralgia is related to the compression of trigeminal nerve by blood vessels. The secondary cause is caused by the compression of trigeminal nerve by meningioma and multiple sclerosis. Therefore, the first step in the treatment of trigeminal neuralgia is to distinguish whether it is primary or secondary, and take appropriate treatment measures according to the cause of the disease. After the occurrence of trigeminal neuralgia, you should consult a doctor in time and choose medication under the guidance of the doctor, not self-medication.
