Primary Actions

Stabilizes the exterior and stops spontaneous sweating - Ru Dao Gen is a classic convalescent herb for weak surface Qi with daytime sweating, post-illness fatigue, and easy fluid loss.
Checks night sweating and clears deficiency heat - it is used when Yin deficiency or prolonged illness causes evening heat, steaming bones sensation, or sleep-related sweating.
Benefits the Stomach and generates fluids - traditional use extends to dry mouth, irritability after fever, and poor recovery when fluids are depleted but stronger tonics would be too cloying.

Ru Dao Gen with Fu Xiao Mai and Mu Li - a classic pairing style for spontaneous sweating and night sweats from deficiency.
Ru Dao Gen with Di Gu Pi and Bie Jia - used when deficiency heat and low-grade fever accompany chronic sweating.
Ru Dao Gen in convalescent sweet decoctions - a mild restorative approach when post-illness thirst, poor recovery, and depleted fluids are more prominent than full excess heat.

Me & Qi describes Nuo Dao Gen as sweet and neutral, entering the Liver, Lung, and Kidney to stop spontaneous and night sweating while tonifying the Stomach and generating body fluids.
Traditional use is strongest in deficiency sweating and recovery states, not in exuberant excess heat or damp obstruction.
SOURCE NOTE: the original import carried the nonstandard pinyin Ru Dao Gen, but the Chinese name 糯稻根 and current references support Nuo Dao Gen or Nuo Dao Gen Xu.
