Are there any herbs, nootropics or medications that are antagonists?

for original question:

Antihistamines are H1/H2 antangonists, used to potentiate opiates.

yohimbine is a Sertonin antagonist, some people seem to dig it.

Most derliants are M-Ach antagonists

yohimbine is an a-2 adrenoreceptor antagonist afaik.

And IMO it is the worst, most disgusting stuff ever to come out of a plant, anywhere.

since it is still sticking around and to re-emphasize how banal the thread is why don;t we simply point out caffeine is an antagonist, i think that is something you might have come across

 

[Ham-milton]

caffeine isn't an antagonist, it's a virus.

silly guy!

 

[LuxEtVeritas]

oooops

 

[MurphyClox]

Yeah! Hammilton is right. It stems from the family of Senselessviridae, the same to which Ketamine belongs, too.

Brings a new meaning to antisense DNA strands...

Yeah yeah, usual cavets for wiki...which lists it as both A-2 and various serotonin subtype antagonist.

and imho...its a crappy stim, but still not that horrible...
