The story of Drynaria treating broken muscles and bones

According to legend, Emperor Mingzong of the Tang Dynasty was out hunting when a leopard suddenly jumped out, causing broken muscles and broken bones, and blood flowing out. I asked the imperial doctor to use internal medicine, but various methods of applying external medicine did not work, and the pain was not relieved. So he ordered Zhang Huangbang to summon talented people from all over the world to treat Xuanzong's back and waist pain.

At this time, a folk doctor came and offered him a piece of monkey ginger herbal medicine. On the one hand, decoct the soup and take it internally, and at the same time, crush it and apply it externally. Tang Xuanzong's illness was quickly cured. Emperor Longyan was overjoyed and asked, what is the name of this medicine? The doctor replied, it is called monkey ginger. The emperor said that the name was not pleasant and indecent. Let me give it a name, "Drynariae".

Among the materia medica of the past dynasties, Drynaria is the only medicine that can be named by the emperor himself. This may be the key reason why the name "Drynaria" has gradually become famous and has become an important medicine for treating bruises and injuries.

Sun Simiao, a famous doctor in the Tang Dynasty, said: "Take two or three liangs of medicated wine in winter and stop at the beginning of spring. If this method is used throughout your life, all diseases will not occur." Cases of ejaculation

Li Shizhen described a case of using Drynaria to treat chronic ejaculation in "Compendium of Materia Medica".

The son of the governor of Wei had been suffering from ejaculation for a long time. Many doctors were invited to diagnose and treat him, but they were ineffective. He was already on the verge of death, so he finally had to ask Li Shizhen for treatment. Li Shizhen grinded Drynariae into powder and put it into pig kidneys, simmered it and gave it to him, and his diarrhea immediately stopped after eating.

Li Shizhen analyzed that the kidneys govern defecation and defecation, and prolonged diarrhea will inevitably lead to kidney deficiency. Therefore, diseases of the spleen and stomach cannot be treated solely. Since many doctors had failed with their medications, Li Shizhen gave up on treating the spleen and stomach. Considering that chronic diarrhea was probably caused by kidney deficiency, she started by nourishing the kidneys and achieved good results.

Facts have proved that Li Shizhen’s analysis and judgment is very correct. Based on syndrome differentiation and treatment, the disease can be cured by medicine.

Today's Drynaria is mainly used clinically for two aspects:

1. Fractures and fractures: Drynaria has the effect of promoting fracture healing and treating osteoporosis.
