mechanism:
Active alkaloid is cytisine, a nicotinic acetylcholine receptor agonist. NOT a classical 5-HT2A psychedelic. (1) · Active oils are myristicin, elemicin, and safrole, phenethylamine precursors that may be aminated in vivo to MMDA, TMA, and MDA respectively (Shulgin's 'essential amphetamines' hypothesis). (1) · Active principle is thujone, a GABA-A antagonist (the opposite of most CNS depressants). Also present in cooking sage (''Salvia officinalis''), tansy, and ''Thuja'' cedars. (1) · Caffeine (1.5–2%) + theobromine + kolanin (a glycoside). (1) · Caffeine (highest of the ''Ilex'' genus) plus saponins that produce ritual vomiting at high doses. (1) · Caffeine (sometimes called 'mateine' historically, though chemically identical), theobromine, theophylline, plus polyphenols. (1) · Caffeine + theophylline + L-theanine. L-theanine (an amino acid unique to tea) modulates glutamate and produces an 'alpha-wave' calming overlay on caffeine's stimulation, hence tea's reputation as a 'cleaner' stimulant than coffee. (1) · Contains the β-carboline alkaloids harmine, harmaline, and tetrahydroharmine, reversible monoamine oxidase inhibitors (RIMAs) that allow oral DMT to reach the brain. (1) · Highest natural caffeine content of any plant (2–7% by dry weight, ~2–4× coffee). Caffeine is bound to tannins, producing a slower release than pure coffee caffeine. (1) · Primary alkaloid is cocaine, a tropane that blocks reuptake of dopamine and norepinephrine (and serotonin). At low oral doses from leaf chewing, the slow release favors NE-mediated alertness over DA-mediated euphoria. (1) · Primary alkaloid is theobromine (3,7-dimethylxanthine), with minor caffeine. Also contains phenethylamine, anandamide (an endogenous cannabinoid), tryptophan (serotonin precursor), and flavanols. The combined effect is mild stimulation + mood elevation. (1) · Tropane alkaloids: hyoscyamine (dominant; the racemic form is atropine), scopolamine. Competitive muscarinic antagonism. (1) · Tropane alkaloids: hyoscyamine, scopolamine, atropine, apoatropine. (1) · Tropane alkaloids: hyoscyamine, scopolamine, in higher seed concentrations than belladonna or datura. (1) · Tropane alkaloids: scopolamine (dominant), hyoscyamine, atropine. Competitive antagonism at muscarinic acetylcholine receptors. (1)
preparations:
Bark/woody stem decocted with a DMT-source plant (''Psychotria viridis'', ''Diplopterys cabrerana'') to make ayahuasca (1) · Bright red seeds, traditionally ingested or smoked. Highly toxic, narrow margin between active and lethal (1) · Dried leaves and twigs, infused in a gourd (''mate'') and drunk through a metal straw (''bombilla'') (1) · Dried leaves, infused. Six major processings: white, green, yellow, oolong, black, pu-erh (1) · Dried leaves; absinthe liqueur (120–160 proof, with hyssop, lemon balm, fennel, anise, sometimes Acorus calamus) (1) · Fermented and roasted seeds, ground. Mexican tradition: drunk with chili, cornmeal, achiote. European tradition: with sugar and milk (1) · Flowers or leaves infused or smoked. Highly variable potency; narrow toxic margin (1) · Fresh nuts chewed; also dried and powdered (1) · Ground dried seed (nutmeg) or fruit aril (mace); occasionally infused (1) · Leaves and seeds, traditionally smoked or infused. Possibly the original Pythia oracle plant (1) · Leaves chewed with a pinch of slaked lime (the lime converts cocaine HCl to freebase for buccal absorption); also drunk as tea (''mate de coca'') (1) · Leaves, berries, root. Historically: belladonna cigarettes ("Asthmador") OTC in US until the 1970s (1) · Roasted seeds ground to powder, mixed with water; commercial syrups and energy drinks (1) · Root, traditionally carved into ''mannikens'' or infused into wine (1) · Toasted leaves and twigs decocted to a near-black concentrate (1)
