Melissa is also called bee balm.
And dosage-not fussy or sensitive, I don't weigh it, I just grab enough to fill a liter jug, add hot water and honey, infuse, and drink like tea or coffee.
Its mild, yet highly effective, but suitable for ingestion as a beverage, also, as opposed to a drug. I drink it by the liter, with no ill effects (although I do have seizures, and take chlormethiazole, which is a potent, barbiturate/neurosteroid site agonist at GABAaRs, so I have a crosstolerance to GABA-TA inhibitors im sure) but balm is about as non-hazardous as you can get.)
Actually, i really reccomend chlormethiazole. Its a hell of an antiseizure med. GABA agonist, as stated IIRC either barb binding site or neurosteroid site agonist, not a teratogen. Potent, does have a very steep dose response curve though, unlike benzos, an overdose can easily prove lethal. And DO NOT FUCKING DRINK ALCOHOL ON THIS STUFF, it has a specific potentiating effect. Enough, despise my tolerance to GABAergics, to make a single shot of spirit render me unconscious.
