A kratom tincture is a liquid extract in which kratom alkaloids are dissolved in a solvent such as alcohol, typically sold in a dropper bottle. It is a concentrated liquid format rather than a leaf product.
Like other extracts, a tincture is far stronger by volume than plain leaf, so its label and Certificate of Analysis are the references for alkaloid content. See the Extracts hub and Extract.
