Overview

Liriope tuber takes its name from the shape of its root, which forms small beads resembling wheat grains — hence 'wheat-tuber winter herb' in the original Korean-Chinese name. The Donguibogam prizes it for moistening dryness and heat left behind by illness, especially when thirst and a dry mouth persist.

TranslationIts nature is slightly cold, its taste sweet, and it is non-toxic. It chiefly treats taxation-deficiency with lingering heat and dry-mouth thirst, and treats lung wasting with purulent expectoration.

Frequently asked questions

Where does the name 'wheat-tuber winter herb' come from?

The Donguibogam notes that its root forms a string of small beads shaped like wheat kernels, remaining green through winter — the source of both its Korean and Chinese names.

Why is it paired with ginseng and schisandra?

This combination, Saengmaek-san, is a classic summer formula for replenishing qi and fluids lost to heat and sweating — each herb tonifies a different aspect: qi, fluids, and astringing.
