Yu Ping Feng Oral Liquid, as a formula to benefit Qi and consolidate the surface, is usually taken for 1-2 weeks after excessive sweating from external sensations, as a retraining i.e. to prevent excessive sweating and injury to the body. If the patient is usually weak in lung qi and often sweats, Yu Ping Feng may be taken for a longer period of time, sometimes up to 2-3 months. If the body is not weak or if the sweating is too much with the medicine, the sweating may not stop and the cold is cured, but the sweating still does not stop, then the treatment is too much. The recovery treatment is not troublesome, as Yu Ping Feng has the function of benefiting the qi and fixing the surface, preventing the external evil from entering the interior, and transporting the qi of the middle jiao, which is generally effective in 1-2 weeks. However, if you are suffering from long-term lung qi deficiency, and you are prone to sweating or sweating non-stop when you are not paying attention, you may be suffering from yang qi deficiency triggering spontaneous sweating, you can also use Yu Ping Feng Oral Liquid for treatment, but because you have to adjust your constitution, the medication time is relatively long, usually taking 2-3 months.
