SWEAT BATHs help the body to rid itself of toxins that cause illness. "Sit in a tub of water as hot as you can tolerate. Add a couple of tablespoons of ginger powder, a handful or rosemary or mint leaves, or other aromatic herbs. (It is best to put these herbs in a mesh bag to keep from having to clean out your tub after the bath.) An alternative is to add a quarter teaspoon of lavender oil, tea tree oil, or some other pure essential oil. Drink plenty of water or a fragrant herbal tea before sitting in the bath.

VITAMIN C: At the onset of a cold, take 1000mg of Vitamin C and repeat this dose every hour until symptoms cease.
