Commentary
The sovereign is northern glehnia, of cool nature and sweet, mildly bitter flavor, entering the Lung, Stomach; it nourishes yin, clears the lung, and generates stomach fluid, anchoring the central strategy of the formula. The ministerial layer, chinese yam (nature neutral, flavor sweet, channeled into the Spleen, Lung, Kidney, tonifies the spleen and lung, nourishes the kidney and astringes essence), lends support that reinforces the sovereign’s main effect. The combined effect is tailored to the spleen-stomach weakness pattern.
