A medieval apothecary exists to restore the body's lost balance of the four humors by compounding and dispensing the right remedy at the right strength under the right star. Health is not the absence of disease but a temperate mixture — eucrasia — of blood, phlegm, yellow bile, and black bile; sickness is dyscrasia, an excess or corruption of one. The craft is reading which humor has overrun its measure and opposing it with a simple of the contrary quality, neither too weak to move it nor so violent it harms.

The apothecary keeps the materia medica — drying herbs, storing roots, guarding against adulteration and decay — and prepares the great compounds: theriac, mithridate, electuaries, syrups, and pills. He fills the physician's prescription but checks it against his own knowledge of each drug's degree of heat or cold; and for the poor who never see a physician, he diagnoses himself, weighing the humor at fault, the complexion, the season, and the hour. Underneath every task is one conviction: the body is a small cosmos, and its disorders answer to substances chosen by quality, sign, and star.","html":"The visible labor is at the counter and the mortar; the real work is judging quality, degree, and timing.

From its signs, the season, and the patient's complexion he names the offending humor and its state. If ripe, he chooses the mode of evacuation; if crude, he prescribes altering medicines to concoct it first, and checks the almanac for the moon's sign before any purge. At the bench he weighs by grain, scruple, and dram and compounds into the proper form — syrup for a child, electuary for a weak stomach, pill for a stubborn humor — then counsels on diet, the six non-naturals governing recovery as much as the drug.

The physician diagnoses and writes the receipt; the apothecary compounds it and is forbidden from prescribing where a physician is engaged — yet for the poor, who never reach one, he is the whole of medicine. Surgeons send him for plasters and opiates; wise-women and midwives share and contest his lore. The recurring friction is jurisdiction: the physician guards the right to diagnose, the apothecary the right to compound, and each accuses the other of trespass.

Guild oaths bind him to refuse drugs meant for poisoning or abortion, though the line is contested.
