7. The Law Of Selective Elimination

All injurious substances which gain admittance by any means into the living organism are counteracted, neutralized, and expelled by such means and through such channels as will produce the least amount of harm to living structure.

Examples of this law are illustrated by the apparent actions of drugs which are introduced into the body and, depending on the composition of the drug, seem to affect certain parts of the body in a particular way. Actually, as we have discussed earlier, the body is acting on the drug according to its chemical character, using the point of least resistance for counteractive and eliminative measures, depending on what part or parts of the body can do so with the least ill effects.
