Trimethoxyamphetamine Trimethoxyamphetamine TMAs, also known as trimethoxyamphetamines, are a family of isomeric psychedelic hallucinogenic drugs. There exist six different TMAs that differ only in the position of the three methoxy groups: TMA, TMA-2, TMA-3, TMA-4, TMA-5, and TMA-6. The TMAs are analogs of the phenethylamine cactus alkaloid mescaline. The TMAs are substituted amphetamines, however, their action does not resemble that of the unsubstituted compound "amphetamine", which is a stimulant and not a psychedelic. It is reported that some TMA's elicit a range of emotions ranging from sadness to empathy and euphoria. TMA was first synthesized by Hey, in 1947. Synthesis data
Hallucinogenic plants in Chinese herbals Hallucinogenic plants in Chinese herbals For over two millennia, texts in Chinese herbology and traditional Chinese medicine have recorded medicinal plants that are also hallucinogens and psychedelics. Some are familiar psychoactive plants in Western herbal medicine (e.g., "làngdàng" 莨菪 ""Hyoscyamus niger", black henbane"), but several Chinese plants have not been noted as hallucinogens in modern works (e.g., "yúnshí" 雲實 ""Caesalpinia decapetala", cat's claw" flowers). Chinese herbals are an important resource for the history of botany, for instance, Zhang Hua's c. 290 "Bowuzhi" is the earliest record of the psilocybin mushroom "xiàojùn" 笑菌 (lit. "laughing mushroom", ""Gymnopilus junonius", laughing gym"). There
