Urticaria cannot be treated with vinegar. Urticaria, commonly known as rubella, is an edematous reaction caused by the dilation and increased permeability of small blood vessels in the skin mucosa, which usually subsides within 2-24 hours, but new rashes occur repeatedly and the disease lasts for several days to several months. The main treatment of urticaria is to get rid of the cause of urticaria as soon as possible and avoid the triggering factors, and at the same time you can use medications such as antihistamines, as well as glucocorticoid creams and immunosuppressants for treatment. For the treatment of urticaria, certain drugs that reduce vascular permeability, such as vitamin C and calcium, can be used in combination with antihistamines, and those caused by infectious factors can be treated with appropriate antibiotics.
