According to Chinese medicine practitioners, sweaty feet may be a normal physiological condition, or it may be caused by yin deficiency and internal heat, which can be improved by dietary adjustments such as a light diet and medication such as Liufei Di Huang Pill. 1. Dietary adjustments: Yin deficiency and internal heat mainly refers to deficiency of yin fluid, which manifests itself as heat in the hands and feet, night sweating (sweating abnormally after going to sleep, but the sweating stops after waking up), heartburn and dryness and heat, etc. A light diet should be maintained, avoiding spicy, cold and greasy foods. 2. Medications: Patients with foot sweating caused by yin deficiency and internal heat can be treated with medications that nourish yin and tonify the kidneys, such as Liuwei Di Huang Pill, which is composed of Poria cocos, Mudan Pi, and Radix Rehmanniae Praeparata, and can be used to treat foot sweating caused by insufficient yin in the kidneys. If you need to use medication, it is recommended to use medication under the guidance of a doctor, not blindly self-medication to avoid adverse effects.
