Because the sequelae of herpes zoster in western medicine are caused by the nerve invasion of herpes zoster virus on nerve endings, and western medicine has never had a specific drug to kill the virus, it generally uses drugs or physical methods, such as lasers, to anesthetize the damaged nerves, and of course some patients have pain conduction anesthesia. In a word, the purpose is to make patients no longer feel obvious pain, rather than pain does not exist. When the anesthetic effect slowly dissipates, what kind of neuralgia and how painful it was before can only be aggravated, and there is no hope of relief. In the long run, patients will gradually have a question in their hearts, "Can the sequelae of herpes zoster be cured?" .

In fact, whether the sequelae of herpes zoster can be completely cured depends on the choice of treatment methods for patients. It doesn't mean that the sequelae of herpes zoster can't be cured by ordinary painkillers or ordinary nerve tissue therapy in western medicine. Wuwei Qingxi mixture, which has a good effect on the treatment of herpes zoster sequelae.

The residual toxin of damp-heat is not exhausted, and the heat turns into toxin for a long time, and blood stasis blocks the collaterals, but the metabolic waste of zang-fu organs and tissues cannot be discharged through the collaterals, and the accumulation of toxins damages the collaterals and aggravates the damage of nerve cells, so the pain lasts. The low immunity of patients is also an important factor in the occurrence of herpes zoster sequelae. The patient of this disease is old and weak for many years, and the viscera function is low. He suffers from herpes zoster for a long time, which hurts yin and blood, showing that yang loses temperature and yin loses dampness. Yang deficiency, deficiency of yuan yang, and poor clearing of yang; Deficiency of yin and blood and tense veins will lead to "pain due to infidelity", which has the characteristics of persistent disease, refractory gingivitis and long course of disease.

Domestic herpes zoster experts believe that this is due to the lack of healthy qi, the invasion of evil spirits, qi stagnation and blood stasis, damp-heat stasis and collateral stasis. Traditional Chinese medicine will have more advantages than western medicine, but according to the pathology of deficiency of vital qi (low immunity), stagnation of qi and blood, and obstruction of meridians (poor microcirculation), eliminating evil spirits is the glory and dredging the body, nourishing yin and benefiting qi, promoting blood circulation and searching for toxins, and dredging collaterals. Combined with oral administration of Paidu Tongluo capsule and deep-seated elimination of pathogenic factors and strengthening the body resistance to gold, both internal and external treatment can make qi and blood flow smoothly, achieve the effects of combining dredging with glory, reaching the disease site, removing the disease and recovering, and achieve the effect of treating both the symptoms and root causes.
