Galen from Pergamon (129-c.200 CE) was a Greek physician and scientist whose writings contain three references to cannabis. Ancient medicine was founded on the utilization of herbs, and physicians were often developed herbalists. Personal observations, popular superstitions, medical experience, and information from other sources were collected in ancient medical treatises, which concentrated on the description of plants and their uses.
In “De alimentorum facultatibus,” he describes cannabis in some detail and says some people eat it toasted along with other substances to increase the pleasure of drinking during the meal. But, he warns, cannabis has a “hot” characteristic such that, if it is ingested in too much quantity in a short time, it is “painful for the head.”
In another text, he says that the juice from cannabis can be used for ear pain but too much can cause male impotence. And in a third text, he repeats the earlier point: “in the same way the agnocastus’ seed and the cannabis’ seed are not only pharmacological, but painful for the head.”

Too much cannabis leads to seeing devils, Pen-ts'ao Ching (c. 50 CE)
The use of cannabis in medicine was a very early development. But according to a famous early book on Chinese herbal medicine, the Pen-ts'ao Ching (The Divine Farmer's Materia Medica), "ma-fen (fruits of hemp) . . . if taken in excess will produce hallucinations (literally seeing devils)." On the other hand, moderate use over a longer time has benefits. "If taken over a long term, it makes one communicate with spirits and lightens one's body."
The Pen-ts'ao Ching is attributed to the legendary Emperor Shen Nong, who is said to have taught the Chinese people how to farm. The book was actually compiled in the first century CE but was apparently based on early traditions passed down from pre-historic times.
Pedanius Dioscorides includes cannabis and opium in his list of medicines (c. 77 CE)
"De Materia Medica" (On Medical Matters), written by Pedanius Dioscorides, was the leading pharmacological text for 16 centuries. The five-volume work contains excellent descriptions of nearly 600 plants, including cannabis (for lessening inflammation, treating earache, and birth control). It also describes the medicinal value of animal products such as milk and honey and discusses chemical drugs such as calcium and arsenic. Dioscorides clearly refers to sleeping potions prepared from opium and mandragora as surgical anesthetics.
"De Materia Medica" is the prime historical source of information about the medicines used by the Greeks, Romans, and other cultures of antiquity and became the precursor to all modern pharmacopeias.
