After the herpes zoster rash subsides, if the local skin still has pain and discomfort that lasts for more than 1 month, it is called postherpetic neuralgia. It is the pain left over from herpes zoster. It is a severe and intractable pain. A light touch can produce severe and unbearable pain. The patient's pain is often spontaneous lightning-like or tearing pain, which may occur during an attack. It makes patients sleep and eat uneasily, and most patients are often accompanied by obvious and persistent burning pain. It can be said to be a potential killer of the health of middle-aged and elderly people. Therefore, when it comes to treatment, we should also start with the cause of postherpetic neuralgia. Postherpetic neuralgia, one of the stubborn pains that is difficult to cure in modern medicine, is caused by the residual poison of damp and heat remaining in the body, which turns into heat and poisons over time, blood stasis blocks the collaterals, and the metabolic waste of the organs cannot be discharged through the collaterals. , the accumulation of toxins further damages the collaterals, so the pain is particularly long-lasting. According to the opinion of Dr. Zhao Jianjun, a well-known domestic herpes zoster expert, this disease is caused by internal deficiency of healthy qi, external invasion of evil toxins, qi stagnation and blood stasis, accumulation of dampness and heat, and blocked channels. Traditional Chinese medicine can be fully utilized to treat non-irritating and non-irritating treatments. The therapeutic advantage of side effects is based on the pathology of the disease: deficiency of righteousness, stasis of qi and blood, and blocked meridians. The treatment principle is to strengthen the body and eliminate evil. Using the methods of nourishing yin and replenishing qi, activating blood circulation to remove toxins, and unblocking collaterals to relieve pain, we can achieve the effect of treating both the symptoms and the root causes. Wuwei Qingzhu Mixture, which has been certified by the U.S. Food and Drug Administration (FDA), is the best choice to achieve this therapeutic effect. Of course, it is also an excellent answer to the question of "treatment". Wuwei Qingzhu Mixture can be applied internally and externally. Externally, blister-containing analgesic liquid, dampness-removing and muscle-promoting ointment and residual nerve repair analgesic ointment can be applied to the affected area to improve local blood circulation and promote the smooth flow of blocked nerves; also take Paidu Tongluo Capsules orally. And deep-level evil-removing and strengthening gold, it can treat the inside and outside at the same time, so that the qi and blood flow, the meridians are unobstructed, and the damaged nerves can be repaired and unblocked. This mixture was repeatedly verified and refined by Professor Zhao Jianjun on the basis of ancient traditional Chinese medicine prescriptions passed down from his ancestors, combined with modern medical methods. It has a very significant effect in treating postherpetic neuralgia, and has benefited nearly 10,000 people. Traditional Chinese medicine has a saying: Where there is a deficiency, there is a place for evil. The first benefit of Wuwei Qingzhu Mixture is to support the body's healthy energy. If the healthy energy is sufficient, cold and damp evil will not dare to invade. Taken together, the Wuwei Qingzhi Mixture can replenish qi and nourish yin, clear away heat, detoxify and dry dampness, activate blood circulation and remove blood stasis, unblock meridians, rejuvenate qi and blood, unblock meridians, and smooth qi and blood. In this way, it can expel damp-heat evil poisons from the body and repair the disease. The damaged nerves are unblocked and the pain is stopped, so postherpetic neuralgia can be cured.
