Introduction

When eczema presents with skin erythema, papules, and exudation, and the patient simultaneously exhibits symptoms such as thick, greasy tongue coating, sticky bowel movements, and heavy limbs, it may be related to excessive internal dampness. Accumulation of dampness in the skin can easily trigger inflammatory responses, leading to eczema flare-ups or worsening. In such cases, resolving dampness through regulation may help alleviate symptoms.

Generally, some cases of eczema are associated with excessive internal dampness, manifesting as skin oozing, itching, and a sensation of heaviness in the body. However, most eczema cases are triggered by factors such as allergies or impaired skin barrier function, and are not directly related to internal dampness. If in doubt, it is advisable to consult a healthcare professional promptly. Detailed analysis is as follows:

When eczema presents with skin redness, papules, and oozing, and the patient simultaneously exhibits symptoms such as thick, greasy tongue coating, sticky bowel movements, and heavy limbs, it may be related to excessive internal dampness. Accumulated dampness in the skin can easily trigger inflammatory reactions, leading to the onset or worsening of eczema. In such cases, treatment aimed at eliminating dampness may help alleviate symptoms.

If eczema is caused by identifiable allergens—such as pollen, dust mites, or specific foods—or results from dry skin, frequent scratching causing skin barrier damage, or prolonged exposure to dry or humid, hot environments, it is not related to internal dampness. The primary triggers in these cases are external irritants or intrinsic skin issues, requiring targeted avoidance of triggers and skin barrier repair.

Determining the cause of eczema requires a comprehensive evaluation of symptoms and professional medical assessment. Daily care should include maintaining clean and well-moisturized skin and avoiding known irritants. If eczema persists, recurs, or spreads, prompt medical consultation is recommended to identify the underlying cause and receive appropriate treatment.
