What does decoct mean?
"Decoct" is a formal verb meaning to extract the essence, flavour, or active constituents of a substance by boiling it in water, typically over sustained heat. It is most at home in the vocabulary of herbalism and traditional medicine, where practitioners decoct tough materials such as roots, barks, and seeds — substances that require prolonged simmering to yield their properties, unlike delicate leaves suited to simple infusion. By extension, the word can describe concentrating any substance by boiling. Though rarely heard in casual conversation, it survives robustly through its noun form, "decoction," which names both the process and the resulting liquid extract. Derived from the Latin decoquere, "to boil down," it shares that root with the familiar words "cook" and "concoct." For readers of historical medical texts or enthusiasts of herbal remedies, "decoct" remains a precise, useful term marking a specific and ancient method of preparation.

Etymology of decoct
Decoct comes from the Latin decoquere, formed from de- (indicating removal or reduction) plus coquere, "to cook." It passed into English in the late sixteenth or early seventeenth century via learned and scientific usage, particularly in pharmacy and alchemy. Its closest relative is "concoct," from the same verb with a different prefix, while the root itself underlies "cook" and, through praecoquere, "precocious."
