If I say it 1000 times I have not said it enough. Kratom is not an opiaoid, it is an Analgesic Indole, although one extremely minor constituent IS opioid, 7-Hydroxy-mitrgynine. Sadly, it is only ever less than half of one percent in total alkaloidal content.
As for the geographical labels like "Indonesian," "Bali," Thai," etc...it is ALL nonsense. Even on the same tree a leaf will have highly varying akaloidal content so attaching a name to it is not making any kind of difference, even if it were soemhow accurate and I am here to say it is not. ALL Kratom is being grown in one of two places on Earth, unless you are in the region yourself and picking it.
