A baking soda bath, oatmeal bath, milk compress, asafoetida powder, and herbal tea are good homemade remedies for hives, according to HowStuffWorks. Consuming plenty of vitamin C and bathing with a solution of basil tea may also aid in counteracting hives outbreak.
Taking 2,000 milligrams of vitamin C per day may help lower histamine levels, which trigger outbreaks of hives; however, excessive consumption of the vitamin may give rise to diarrhea and kidney stones, states HowStuffWorks. Adding 2 cups oatmeal or 1 cup baking soda to a warm bath and soaking in it may aid in alleviating itching. Mixing 1/4 teaspoon asafoetida powder, which produces a garlic-like smell, with 4 tablespoons castor oil, and applying the concoction to the affected area may help alleviate hives.
Mixing a quart a jar of boiling water with 1 ounce dried basil, letting the solution cool, and then bathing with it is a remedy the Chinese used to counteract hives, according to HowStuffWorks. To use a cold compress, wrap ice in a towel, and use it to compress the affected area for about five minutes, four times a day. Ice constricts blood vessels and aids in reducing swelling. Soaking a cloth in cold milk and putting it over the affected area may help calm the hives as well.
