Haven't had gabaergics in a long time, so decided to give this one a try.
soaked ~10g of dried thyme overnight in about 0,7dl of olive oil and plugged it. It gave me some sedative effects, clearly distinquishable from placebo. I'd say it was equivalent to about 10-20mg of valium. It seemed to come up pretty slowly and last many hours. I suspect high amount of oil makes it absorb slowly in the rectum.
