Yu Ping Feng Oral Liquid is mainly for the treatment of spontaneous sweating caused by the deficiency of the guard and the lack of consolidation of the guard’s surface leading to the outflow of fluids, and the symptoms of Qi deficiency are usually more obvious. If the symptoms appear within a short period of time, the symptoms can be improved after about 2 weeks of taking it. However, if the symptoms are more than half a year or more than one year, it needs to be taken for a long time to achieve the effect of health care. Among them, Astragalus, Atractylodes, and Bifeng, we can catch them back from the herbal store and then decoct them ourselves. The power of herbal soup is much stronger than the oral liquid bought in the market, so for some patients who have been sick for a long time, they can be decocted and taken, which will be more effective. Taking oral liquid alone is only a treatment for some deficiency evidence of a shorter period of time and may not always be very effective.
