Dr Jack Parsons, MD (Santa Barbara, Calif) on 09/24/2008:

All you need to take is 2 tablespoons twice a day, to afford the rapid results.

Here is the formula:

1 white onion, cut into quarters
1 entire head of garlic peeled
4 habaneros destemmed, but with seeds and veins intact
4" horseradish root, peeled and chopped
4" ginger root, peeled and chopped
1 quart of [organic apple cider] vinegar.

Place all ingredients and puree, then bottle into a quart jar, cap and store at room temp. Shake the bottle, and take 2 tablespoons when symptoms manifest. Or.. take 1 tablespoon every day, to prevent the flu and colds from ever taking hold. My patients who have done this, haven't contracted a flu or cold in years.
