Cannabis sativa from antiquity to the Middle Ages


I wrote this as a bit of a giggle for my local SCA newsletter. I am not advocating for the use of Cannabis sativa for psychotropic purposes, but I do believe that we should be using the fibre in place of wood. It also makes pretty good shirts.

What is the difference between hemp and cannabis?

They are, in fact, the same plant. The difference is that one was bred for industrial fibre production, and the other was bred for the production of THC (tetrahydrocannabinol), the chemical which gets you ‘high’. The original, wild Cannabis sativa plant was something in between the two in form, function, and use.[1]


Origins-

Archaeological evidence is sparse, but Cannabis sativa (from the Greek word kannabis) may have originally come from Central Asia (the area between the Caspian Sea and Mongolia), or South Asia (the area between the Himalayan mountains and the Indian Ocean).

The etymology seems to follow that an earlier, late-Paleolithic or early Neolithic word denoting the seed and fibre uses of the plant originated in the Indo-Iranian root word of *kan or *ken, and a later word denoting the narcotic uses of the plant spread from the areas of Iran or Northern India.[2] Associated words from various cultures- Armenian- kanep, Bulgarian- konop, Old English- hænep, Old Norse- hampr. The word kannabis was a Greek transliteration of the Thracian name for hemp.[3]

The Egyptians and Assyrians knew about cannabis, but it was not known about in Greece until the 5th century BCE, when Herodotus describes seeing a vapour bath during a burial ritual where the Scythians he was visiting burned cannabis seeds in a tent which functioned like a sweat lodge. He related that the Scythians ‘shouted for joy’. He also described hemp fibres as being almost indistinguishable from flax. He had never seen this plant before.[4] By the 4th century BCE cannabis seeds were being eaten recreationally at Symposiums, as lampooned by the comic poet Ephippus.[5]

Cannabis surfaces medicinally in the Greek physician Dioscorides’ herbal De Materia Medica, written somewhere between 50-70 CE, and the Roman works of Galen in the 2nd century CE. The leaves were used as poultices for wounds on horses, skin sores, and nosebleeds, and the seeds were used against tapeworms, or steeped in wine or water and heated for blockages and pain in the ears. But if eaten in quantity they supposedly dried up semen, so were sometimes prescribed for teenage boys who were having too-frequent nocturnal emissions. Galen disapproved of this, however, and said that they should only be used to thin the humours. Cannabis seeds were seen to be warming, drying, harmed the head, thinned the humours, and prevented flatulence.[6]
