Foot dampness
AliasAthlete's foot
Traditional Chinese Medicine Definition
Dampness of the Feet, also known as beriberi, falls under the category of dermatological diseases in traditional Chinese medicine. According to the *Internal Medicine of Traditional Chinese Medicine*, dampness of the feet is caused by spleen deficiency with exuberant dampness, downward flow of damp-heat, or parasitic toxin infection. Its pathogenesis primarily involves damp-heat accumulating in the skin, or parasitic toxin invasion, leading to skin damage and symptoms such as blisters, erosion, and itching.
In TCM clinical practice, the core pathogenesis of dampness of the feet is spleen deficiency with exuberant dampness and downward flow of damp-heat. Common triggers include improper diet, prolonged residence in damp environments, and excessive sweating. Differentiation should focus on the following key points:
1. Cold, heat, deficiency, and excess: The downward flow of damp-heat pattern is dominated by damp-heat, presenting with blisters, exudation, and severe itching; the blood deficiency with wind-dryness pattern is dominated by blood deficiency, presenting with thickened skin, scaling, and dry fissures with pain; the parasitic toxin infection pattern is dominated by parasitic toxin, presenting with interdigital maceration and whitening, itching, and odor.
2. Key differentiation points: Observe the morphology, color, severity of itching, and presence of exudation of skin lesions, combined with tongue and pulse findings for comprehensive assessment.
General treatment direction note: In TCM clinical practice, the basic principles for treating dampness of the feet are clearing heat and draining dampness, killing parasites and relieving itching, and nourishing blood and moistening dryness. Based on the specific pattern, corresponding formulas may be selected for treatment. Traditional Chinese medicine holds that adjusting lifestyle habits, dietary regulation, and external therapies can help improve the condition.
