Use of Weak Carbolic Acid Lotion

Itching caused due to non-medical conditions can to a great extent be treated using home remedies. Some that can be used to control or treat itching are as follows :

• Take a bath in one can of evaporated milk; you can add other combinations such as oatmeal, baking soda etc. The milk works well to soothe the itching.

• Apply Aloe Vera, cod liver oil, lemon juice, vitamin E oil, wheat germ oil, or witch hazel tea to the itchy area.

• Take burdock, chickweed, goldenseal, plantain, or yellow dock in capsule form.

• Cornstarch helps relieve itching. You can pour some into your bath water or dust it onto your body.

• Scrub the affected area lightly with a pumice stone. Then wash with soap, apply rubbing alcohol, and dab a thick layer of Vaseline over it. This will provide relief from itching.

• Take a bath with a little peppermint or yellow dock to relieve itching.

• Add 2 tablespoons of apple cider vinegar to your bath water to relieve itchy skin.

• Baking soda can be used in cool bath water to soothe other skin irritations and alleviate itching from prickly heat, bee stings, insect bites, and other minor skin ailments.

• Another trusted home remedy is to use a weak carbolic acid lotion or a solution of bicarbonate of soda (commonly known as baking soda) and applying it over the itchy part.
