Is LSD also a plant medicine? Or is it synthetic?
You ask an interesting question that actually also touches on the issue of what we consider to be plant medicine.
LSD is indeed synthetic, but it is true that it is made from lysergic acid, which occurs naturally in ergot alkaloids. However, I must point out that the Claviceps purpurea fungus itself does not produce LSD. The fungus produces ergotamine, ergotoxin, and other ergot alkaloids, but not LSD.
The synthesis of LSD from lysergic acid actually requires further chemical transformations. Albert Hofmann created LSD in 1938 and only later discovered its psychoactive effect by accident. This did not happen because it occurs naturally somewhere, but because the chemical structure proved to act on serotonin receptors in that way.
As for the botanical component: many ancient cultures did indeed use ergot-contaminated grains in ritual ceremonies. Some historians believe that this was the basis for certain mysteries in ancient Greece. But this was unintentional ergot poisoning, not LSD.
There is therefore a difference between a plant medicine that is extracted directly from a plant and a synthetic drug inspired by natural alkaloids. Most psychedelic plant medicines utilize active substances present locally in the plant itself – psilocybin is found in mushrooms, DMT is found in plants, and mescaline is found in cacti.
LSD, on the other hand, is something that must be artificially created in a laboratory. One could say that it is plant-inspired, but not plant-derived. This makes it interesting from a scientific standpoint, but it places it outside the classical definition of plant medicine.
So LSD is semi-natural. However, nowadays it is likely produced entirely synthetically. It is nice to read that people in the past already used LSD-like substances as part of a divine ritual.
