【Abstract】 Diaphoresis is the first of the eight methods of traditional Chinese medicine. It works by opening and relaxing the interstices of the skin, dispersing and promoting the flow of lung qi, so that pathogenic factors are resolved and expelled with sweat. This method is commonly used for exterior syndromes. However, diaphoresis has a wide range of clinical applications. In addition to treating exterior syndromes, it also yields good results in the treatment of internal injury miscellaneous diseases, phlegm-fluid retention, wind-dampness, edema and other diseases. In clinical practice, diabetic nephropathy of the yang deficiency with water retention type is often characterized by symptoms such as lower limb edema, shortness of breath, and chest tightness. For such patients, on the basis of conventional therapies like invigorating the spleen and kidney, removing dampness and excreting turbidity, physicians often add a small amount of diaphoretic herbs to achieve the effect of resolving water qi through sweat and reducing edema. The fundamental principle in clinical practice is always syndrome differentiation and treatment, distinguishing between urgency and slowness, and stopping treatment once the disease is alleviated. Diaphoresis should not be used blindly in clinical practice.更多还原
