Galen, physician to Marcus Aurelius, codifier of the humoral system and canonizer of theriac, dominated medicine from the 2nd century to the 17th, his preparations, plant- and animal-based compound remedies, becoming the pharmacy's definition of medicine itself. Paracelsus attacked the entire edifice in the 16th century, burning the canonical texts at Basel and substituting mineral and chemical remedies, laudanum, mercury, antimony, and the pharmacopeias spent three centuries listing both: galenicals, the vegetable preparations, against chemicals, the mineral isolates. The word survives in pharmacognosy and in the pharmacopeial categories of several countries, the oldest documented schism in the drug trade.
The galenical never died, it waited: the whole modern supplement, herbal, and wellness economy is the galenical dispensary restored, turmeric beside ashwagandha beside the spagyric tinctures, marketed precisely against the chemical side, natural as the banner Paracelsus's enemies never thought to raise. The irony the archive notes: Paracelsus, the chemical revolutionary, is now quoted by the natural side, his dose-makes-the-poison line deployed against the synthetics he invented, the two dispensaries swapping slogans while the customer pays at both counters.
The claim: galenical-versus-chemical is not a medical dispute but a licensing frame, the same plants legal as tea and criminal as extract, the same molecules medicine in one dispensary and contraband in another, the five-hundred-year turf war functioning as the price-control mechanism for both sides, the garden and the retort each selling the other's demon. Verdict: the archive's Drug and Narcotic files have the statutory evidence. Galen compounded treacle for an emperor; Paracelsus dosed miners with mercury; both were right about the dose and wrong about the system, and the shelf you shop today is their argument, still running, priced per capsule. The pharmacopoeia wing's closing note: the plants never took sides. The labels did.
If the split between natural and chemical medicine is a five-hundred-year-old personnel dispute, whose side is the regulation on?
