History
In times past, the hunter-gatherer community kept knowledge about the medicinal properties of various plants, molds, fungi, yeasts, bacteria, minerals and animals. This drug knowledge would include vast amounts of information like what time of the year to look for specimens, where to look, and what part of the plant to use or how to grind a mineral.
As cultures developed in specialization, a person would take on the combined role of physician, pharmacist and priest or minister. These specialized people would be in charge of the community’s physical, mental, emotional and spiritual health.
In English these are often called "medicine men" or shaman. The word shaman comes from Manchu, and is "the only commonly used English word that is a loan from this language". The shaman would use various items from nature to produce a mixture that would be burned, applied, manipulated or ingested in some fashion to help relieve the symptoms the ailing patient.
Eventually, the use of crude drugs reach a zenith in the early 1900s and eventually gave way to the use of purified active ingredients from the natural source. Currently the use and exploration of crude drugs has again gained prominence in the medical community. The realization that many completely unknown substances are yet to be discovered from crude drugs has created a new interest in pharmacognosy and has led to many medical breakthroughs.
In 1907, the Pure Food and Drug Act was implemented and standardization of crude drugs took place. Often the USP would specify what percentage of active ingredient was needed to claim a crude drug met USP standards.
An example of standardization would be as follows (from the United States Pharmacopeia):
Opium is the air-dried milky exudate obtained by incising the unripe capsules of Papaver somniferum Linne or its variety album De Candolle (Fam. Papaveraceae). Opium in its normal air-dried condition yields not less than 9.5 percent of anhydrous morphine.

Famous quotes containing the word history:
“Literary works cannot be taken over like factories, or literary forms of expression like industrial methods. Realist writing, of which history offers many widely varying examples, is likewise conditioned by the question of how, when and for what class it is made use of.”
—Bertolt Brecht (1898–1956)
“He wrote in prison, not a History of the World, like Raleigh, but an American book which I think will live longer than that. I do not know of such words, uttered under such circumstances, and so copiously withal, in Roman or English or any history.”
—Henry David Thoreau (1817–1862)
“All history attests that man has subjected woman to his will, used her as a means to promote his selfish gratification, to minister to his sensual pleasures, to be instrumental in promoting his comfort; but never has he desired to elevate her to that rank she was created to fill. He has done all he could to debase and enslave her mind; and now he looks triumphantly on the ruin he has wrought, and say, the being he has thus deeply injured is his inferior.”
—Sarah M. Grimke (1792–1873)
