Alternative treatments for idiopathic urticaria, also known as hives, include acupuncture, vitamin supplements and relaxation techniques, reports Mayo Clinic. Doctors and patients can also attempt to isolate and eliminate triggers such as certain types of food and physical conditions that bring on hives. Home remedies that ease the symptomatic itching include wearing loose clothing, avoiding harsh cleansers, and cooling the irritated skin with lotions, bathing and moist cloths.
Because high dosages of at least 2,000 mg a day of vitamin C are necessary to change the histamine levels that bring on hives, people should check with their doctors before attempting this remedy, cautions HowStuffWorks. Other supplements that may help relieve symptoms of hives include fish oil, quercetin, and vitamins B12 and D, suggests Mayo Clinic. Patients should also keep track of what they are eating or doing when outbreaks of hives occur in order to identify personal triggers such as food, alcohol, temperatures, physical activities or stress. Foods that often cause hives include chocolate, nuts, tomatoes, fish and eggs, reports WebMD.
Soaking in warm bath water suffused with baking soda or colloidal oatmeal helps relieve the itching that hives causes, according to HowStuffWork. Alternatively, hives sufferers can try a compress with cold milk or applying lavender, sandalwood or chamomile oils. The scent of the oil also helps alleviate hives-inducing stress. Applying an ice pack to the skin relieves swelling by shrinking blood vessels.
