Pharmacopoeia

Quite a lot of my students - whether of chemistry, alchemy, natural philosophy, or unnatural philosophy - have expressed an interest in medical and pharmaceutical knowledge. Well, one of the modern bearers of the great caduceus is Merck & Co., Inc., a "global research-driven pharmaceutical products company" best known for its excellent manuals, an interesting history, and some rather unusual drug-related events.

The link above leads to one of its great public-service endeavours - free manuals for the masses, available online. Enjoy.
