Clinically, there is no such thing as the first formula for expelling phlegm and removing dampness in the past thousand years, and therefore there is no such thing as whether it is effective or not. There are many traditional Chinese medicine formulas for dispelling phlegm and removing dampness, such as Ling Gui Zhu Gan Tang, which is composed of Poria, Gui Zhi, Atractylodes Macrocephalae and other medicines, and can be used for treating chest tightness, shortness of breath, and palpitations (accelerated heartbeat, often accompanied by heartburn) caused by phlegm (a pathological product of impaired metabolism of water and fluid). Wu Ling San is composed of Poria, Poria, Ze Xie and other drugs, and can be used for the treatment of water-dampness internal stoppage (water-dampness stays in the body) caused by urinary incontinence (urine is not smooth), edema and other conditions; Er Chen Tang is composed of half-summer, Chen Pi and other drugs, and can be used for the treatment of coughing and coughing up phlegm caused by dampness and phlegm, vomiting and other conditions. However, there is no such thing as the so-called first formula for expelling phlegm and resolving dampness, so it is impossible to say whether it is effective or not. It is recommended that patients with phlegm and dampness should go to the hospital in time when symptoms occur, and choose the appropriate medication for treatment under the guidance of the doctor.
