Onions
Historically onions were used for allergies, worms, boils, diarrhea, frostbite, urinary incontinence, warts and more. In general, when you’re choosing onions in the store, the best ones will be firm, have a crackly outer skin, and have no scent or just a mild scent. Stronger scented onions are an indication that the onion is starting to spoil. Avoid onions with dark spots or mold.
