Synopsis

Excerpt from Introduction to the Analysis of Drugs and Medicines: An Elementary Handbook for the Beginner

For most practical purposes, however, this difficulty is less of a drawback than might be expected because, for example, in the case of a vegetable drug, by know ing the amounts of several active constituents, we may from a knowledge of its normal composition calculate very closely the amount of crude material originally employed, e.g., having found a mixture to contain per cent of subcarbonate of bismuth and to yield by appropriate treatment, traces of oil of cinnamon (recognized by its odor), gum, resin, meconic acid, and per cent of crystallized morphine, and a small amount of alcohol, it is fair to suppose that the original was a mixture containing the bismuth salt mixed with tincture of Opium and cinnamon water.
