Hello, Im looking for a way to make very potent Kratom tea without drinking the powder. The method I use right now is: I let about 5 grams simmer for about 30 min. (I mixed citric acid in the water), than I let it cool down and filter it through a coffee filter and drink it in about 30 min. The effects set in very fast but only last for about 1 - 2 hours and could be stronger. So are there some tricks to get more mitragynine out of the powder?
