Natural remedies for curing hives from allergies include avoiding triggers such as foods, medications, insect bites and pollen; bathing with cold water; and applying cold compresses to the affected area, according to Mayo Clinic. Wearing soft, cotton clothing can also help in alleviating allergic hives.
Foods that induce hives include fish, eggs, milk, nuts and chocolate, notes HowStuffworks. Tomatoes and strawberries, which stimulate the production of histamine, may cause itching and hives outbreak. Food-related hives appear 30 minutes after eating. Aspirin and penicillin are medicines that may trigger allergic reactions.
To help reduce the symptoms of hives, a person can avoid exposure to excessive heat and certain food preservatives, food colorings, food flavorings and emulsifiers, states HowStuffWorks. However, heat-induced hives heal on their own once the body temperature returns to normal.
Wearing loose-fitting clothing, and dressing or placing bandages over the affected area helps in relieving scratching and irritation, explains Mayo Clinic. Taking cold water baths that contain uncooked oatmeal aid in reversing the problem, too. However, ice cold water may trigger cold-related hives, notes HowStuffWorks.
A patient can keep a diary of what he eats or does, which may help in figuring out the cause of hives, notes WebMD. Medical care may be necessary when hives accompany complications, such as chest pains, difficulty breathing, fainting and tightness in the throat. Other dangerous symptoms include swelling of lips, abdominal pain, diarrhea and dizziness.
