Huangdi Neijing · Suwen (黃帝內經素問) (primary_canonical)
Suwen ch. 23 (Xuanming wuqi) discusses the five qi and five flavors in relation to the zang; ch. 5 supplies the wider five-phase correspondence frame. This is the canonical basis for the flavor-to-organ affinities represented here.

The materia-medica reference explains how taste and channel-entry language is used in modern clinical classification; the five-flavor organ set remains a classical correspondence, not an anatomical taste map.
