In traditional Chinese medicine, this formula is used to tonify qi, strengthen the body's exterior defenses, and support resistance against external pathogens. It is applied in cases of qi deficiency where the body's defensive qi is weakened and unable to protect the surface, leading to increased susceptibility to wind pathogens, recurrent colds, spontaneous sweating, shortness of breath, fatigue, and a weak voice, often accompanied by nasal sensitivity and discomfort triggered by exposure to wind and cold. Commonly used to improve what TCM describes as lung and spleen qi deficiency with impaired defensive function, making the body more vulnerable to external invasion and presenting symptoms such as frequent colds, excessive sweating, and nasal hypersensitivity. Suitable for those with general weakness, a tendency to catch colds easily, excessive sweating, shortness of breath, and chronic fatigue as part of daily health support. It is also commonly used for preventive care during cold and flu seasons or as support during recovery from respiratory illnesses.
