Radical treatment is not easy, only step by step. First, when eczema on the skin is itchy and painful, the most direct way is to apply ointment to remove dampness, which is available in various pharmacies, but only temporarily. Cured, it will also cause hair loss. Second, it is often eaten with porridge that removes moisture, such as red bean and barley porridge. Third, soak your feet with wormwood leaves or ginger every day until you feel a little sweaty. Ask a doctor to prescribe some Chinese medicine for removing dampness and boiling ice. After a long time, water will be reduced and eczema will be improved. But once these methods stop, the humidity will rise again, and the most important thing is to persist.
