Hives, also known as urticaria, are a type of skin rash that are the result of an allergic reaction to a substance, called an allergen, in the environment. Although the cause of hives is not always known, they are often a response to the body releasing histamines, which it does when you have an allergic reaction to food, medicine, or other allergens. Histamine is also sometimes the body's response to infections, stress, sunlight, and changes in temperature. Hives typically manifest as small, swollen, itchy, red areas on the skin that may occur singularly or in clusters. Left untreated, hives usually fade within a few hours, but new ones may appear in their place.  If you want to try to cure your hives at home, there are many different natural remedies to treat your hives.
