Usually translated as “Lesser Yin,” this is the fifth of the Six Channels. This stage is characterized by systemic weakness and dysfunction. A person’s constitution determines whether they develop Shao Yin cold or Shao Yin heat syndrome. Shao Yin cold manifests as fatigue and apathy, diarrhea, poor digestion, cold limbs, profuse clear urine, and palpitations. Shao Yin heat manifests as restlessness, insomnia, mania, dark and concentrated urine, and a dry throat. The last stage is Jue Yin.
