Nan huaijin navel patch is very convenient to use, and can be used at night and day, but it is generally recommended to put it on the navel before going to bed at night and take it off the next morning. However, no matter how good the curative effect of nan huaijin navel patch is, it will not have obvious effect in a short time, and it needs to be persisted for a period of time.
Although nan huaijin navel patch is an external medicine, because it has no direct effect on human body and almost no side effects, it is not suitable for everyone. If it is used by unsuitable people, it will not only improve the symptoms, but will increase the burden on the body. Moreover, it must be used in strict accordance with the dosage during the use process, and it cannot be overdosed, so as not to cause harm to the skin.
At the same time, nan huaijin navel patch can't be used for all diseases. This kind of navel patch is mild, mainly to dispel cold, but its side effects are less than oral medicine, but it is not so magical, and it will be effective if it is not attached.
