What to eat after erysipelas depends on the nature of the disease itself. Erysipelas is a skin disease caused by bacterial infection. Therefore, it is beneficial to eat more foods that clear heat and detoxify after contracting erysipelas, such as winter melon, pumpkin, bitter melon, leafy greens, and mung beans. Additionally, it is also good to consume more vegetables and fruits, such as watermelon and bananas, which are rich in vitamins.
