mechanism:
None (2) ·
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) ·
Caffeine is a non-selective adenosine A1/A2A receptor antagonist; also weak PDE inhibition. Beans contain theobromine (3,7-DMX) and theophylline (1,3-DMX) in smaller amounts. (1) ·
Extremely potent GABAA positive allosteric modulator (1) ·
GABAA positive allosteric modulator (15) ·
GABAA positive allosteric modulator (non-benzodiazepine) (3) ·
GABAA positive allosteric modulator; very long half-life (1) ·
GABAA potentiator (1) ·
GABAA potentiator and direct activator (2) ·
GABAB agonist; GHB receptor agonist (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) ·
Kappa agonist; mu antagonist (1) ·
Kappa agonist; mu partial agonist (1) ·
Kappa agonist; mu partial agonist/antagonist (1) ·
Melatonin receptor agonist (2) ·
Mu-opioid agonist; norepinephrine reuptake inhibitor (1) ·
Mu-opioid receptor agonist (4) ·
Mu-opioid receptor agonist; NMDA antagonist (1) ·
Mu-opioid receptor agonist; prodrug (metabolized to morphine) (1) ·
Mu-opioid receptor agonist; sodium channel blocker (1) ·
Mu/kappa/delta agonist; NMDA antagonist (1) ·
Partial mu-opioid agonist; kappa antagonist (1) ·
Phosphodiesterase inhibitor; calcium channel blocker (1) ·
Positive allosteric modulator of the GABA<sub>A</sub> receptor at the benzodiazepine binding site; increases frequency of Cl<sup>−</sup> channel opening, producing anxiolytic, sedative, hypnotic, anticonvulsant, and skeletal-muscle relaxant effects. (1) ·
Potent mu-opioid receptor agonist (3) ·
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) ·
Prodrug; converted to [[Morphine|morphine]] by [[Enzyme:CYP2D6|CYP2D6]] for analgesic action. (1) ·
Selective GABAA agonist (extrasynaptic delta subunit) (1)
uses:
None (46) ·
Mild to moderate pain; cough suppression (low-dose). (1) ·
No approved medical problem. Encountered as a designer/research benzodiazepine and, increasingly, as an adulterant in illicit opioid supplies. (1) ·

starting dose:
None (51) ·
Adult: 15–60 mg every 4 hours as needed. (1) ·
No medical dose. Active recreational doses reported in the 0.5–1.5 mg range (similar potency to alprazolam). (1) ·
One cup (~40–60 mg caffeine; about half of brewed coffee) (1) ·
One cup (~80–145 mg caffeine for brewed; 60–100 mg for instant) (1)
preparations:
None (46) ·
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) ·
Fermented and roasted seeds, ground. Mexican tradition: drunk with chili, cornmeal, achiote. European tradition: with sugar and milk (1) ·
Fresh nuts chewed; also dried and powdered (1) ·
Illicit tablets ("bars"), powders, blotter, occasionally solutions. No pharmaceutical product exists. (1) ·
Roasted beans, ground; brewed (drip, French press, espresso, cold brew, percolated) (1) ·
Roasted seeds ground to powder, mixed with water; commercial syrups and energy drinks (1) ·

Avoid. Benzodiazepines are associated with neonatal sedation, floppy-infant syndrome, and withdrawal; teratogenic signal weak but non-zero. Designer benzo with no safety data, assume worst-case. (1) ·
Avoid; risk of neonatal opioid withdrawal with chronic use; UM-mother breastfeeding contraindicated. (1) ·
Limit to <200 mg/d (~2 cups brewed) (1)
