Holarrhena antidysenterica contains conessine, a selective H3 antagonist. H3 antagonists are hypothesised to have stimulant, waking, and nootropic properties.
I got ~100 caps x 450mg. Not sure how much I should take for the effects. I ordered the bottle over a year ago and tried taking a few capsules. There was a mild stimulant effect but I dropped the idea as I was not satisfied. Now the expiration date is nearing so I want to give it a second try before throwing it away.
Any ideas what dosage should induce nootropic effects?
