As has been made plain in previous chapters, ideal health is a utopian dream; for the most perfect state of health which it is possible to attain carries a given amount of toxins in the blood and tissues.
Disassimilation means the breaking-down of cells; the result is the accumulation of debris, or waste, which is toxic, and it must be removed from the body as soon as possible. The blood contains a quantity of waste. The organism is adjusted to a reasonable amount of this poison--it is necessary, for it stimulates to action. But when elimination is checked and an oversupply is retained, then excessive stimulation becomes disease-producing. All parts of the body contain poisons. When nutrition is best, there is a balanced state of unorganized and organized ferments. Agreeing with what I have often said, health is only an approximate state. The body at best--under normal conditions--is a laboratory for building tissue, and necessarily becomes the receptacle of the waste and by-products, which are poisonous. An over-supply of toxins is liable to occur at any time from almost any indiscretion.
An extract of the tissues of the body will kill, if it should find entrance into the blood. When elimination is slow, the tissues carry more toxins. Exercise is necessary to force elimination.
It requires about one-fifth as much of liver as it does of muscle to furnish an amount of poison necessary to kill. Then it must be injected into the veins, or it cannot do harm.
Toxicity depends mostly on the nitrogenous matters.
