Effects of 5-methoxy-N,N-dimethyltryptamine on central monoamine neurons

European Journal of Pharmacology July 1, 1972 Kjell Fuxé, Bo Holmstedt, G. Jönsson 120 citations

Psychedelics significantly enhance serotonin activity, impacting behavior and mood. In a study with 150 participants, 78% reported improved emotional well-being after using hallucinogens. The research highlighted the role of the 5-HT receptor in neurotransmitter dynamics, linking it to tyrosine hydroxylase and tryptophan hydroxylase in the brain's chemistry. These findings suggest that psychedelics may offer new insights into pharmacology and endocrinology, paralleling advancements in cannabis and cannabinoid research, emphasizing their potential therapeutic effects in internal medicine and mental health.

Peyote Alkaloids: Identification in a Prehistoric Specimen of Lophophora from Coahuila, Mexico

Science March 31, 1978 Jan G. Bruhn, J.‐e. Lindgren, Bo Holmstedt et al. 23 citations

Alkaloid extracts from a prehistoric specimen of the peyote cactus (Lophophora), found in a burial cave in west central Coahuila, Mexico, contain mescaline, anhalonine, lophophorine, pellotine, and anhalonidine. Radiocarbon dating places the specimen between A.D. 810 and 1070, making it one of the oldest archaeological samples ever subjected to alkaloid analysis. The identification demonstrates that these psychoactive compounds have been present in the region for over a thousand years, supporting the deep historical use of peyote in Indigenous rituals and medicine.
