The Lung and Metal phase are conventionally paired with white foods and pungent flavour in the five-phase correspondence system. The thoracic point is a target-organ projection for visual indexing and is not a claim that white foods directly treat lung tissue.

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.
