You guys are weird, I fucking love the taste of kratom.
Seriously though if you want better effects, don't make teas or brews of any type. Just put a fat teaspoon of leaf or powdered leaf in the corner of your mouth and chew and suck the fuck out of it. Really that's how it should be taken, native people in Southeast Asia chew on the leaves.
There is a significant change in effects, I have made several teas, boils, whatever, but never achieved results as good as merely chewing and then swallowing obviously the powdered leaf. Also I find the tea much more nauseating than eating the leaf, I believe that when you brew it the plant might release some sort of tannin that gives you that gag reflex, chewing or eating the leaf doesn't.
Also if you can buy whole dried leaves, not powder, much much better as the alkaloids don't degrade.
Really it should be taken like Khat or Coca leaves, quid of plant material in the mouth and chew the day away.
