This section of the book is from the "How and When to Be Your Own Doctor" book, by Dr. Isabelle A. Moser with Steve Solomon, published in 1997.
The acutely ill person experiences occasional attacks of distressing symptoms, usually after indiscretions in living or emotional upsets. They have a cold, or a flu, or sinusitis, or a first bout of pneumonia, or a spring allergy attack. The intense symptoms knock them flat and force them to bed for a few days or a week. If they are sick more often than that, they are moving toward the chronically ill category.
People who are acutely ill should stop eating to whatever extent that they are able until the symptoms are gone. During an acute illness, the appetites is probably pretty dull anyway, so why not give a brief fast on water or fruit juice a try.
Most acute conditions are short in duration, usually not lasting more than a week. Allergy attacks, some types of flu, and a first bout of pneumonia may well last for three weeks or a month. The general rule is to eat as little as possible until the symptoms have passed, self-administer colon cleansing, even if you have a horror of such things, and take vitamin supplements, including megadoses of Vitamin C, bioflavinoids, and zinc. (See the chapter on vitamins.) Those having a little experience with natural medicine make teas of echinacea, fenugreek seeds and red clover and quit eating. Eating as little as possible can mean only water and herb teas, only vegetable broth, only vegetable juice or non-sweet fruit juice, even only cleansing raw foods. If you eat more than this you have not relieved your system of enough digestive effort.
After your symptoms are gone it is very important to change your life-style and improve your diet so that you aren't so toxic and don't have to experience an acute illness several times a year when your body is forced to try an energetic detox.
