Hives, also known as urticaria, are raised, red or white welts or bumps on the skin that are often itchy. They can appear anywhere on the body and vary in size. Hives occur when the body releases histamine, usually in response to an allergen or irritant, but they can also be caused by stress, infections, medications, or other triggers. There are two main types: Acute hives: These last for less than six weeks and are typically triggered by allergic reactions or infections. Chronic hives: These last for more than six weeks and often have no clear cause. Treatment: Homeopathy provides safe and permanent cure as it acts on root cause of the problem and not only symptoms.
