Yu Zhu玉竹
Polygonati Odorati Rhizoma · Solomon's Seal Rhizome · Fragrant Solomon's Seal
Overview
A moistening yin tonic that, unusually, does not weigh the digestion down. Sweet and slightly cold, it nourishes Lung and Stomach yin and generates fluids, and it is light enough to be given alongside exterior-releasing herbs when someone with yin deficiency catches a cold. Steamed or dry-fried it becomes warmer and less cloying, favouring the Stomach-nourishing side.
