Bai He Bing 百合病, named after Bai He 百合, lily bulbs, the main herb, used to treat it in the 3rd chapter of the Essentials from the Golden Cabinet by Zhang Zhong-Jing. Bai He also means 100 Meetings which relates to the saying "All the hundred branches (i.e. the channels and collaterals) originate in the Heart and meet in the Lung". It arises when Heat has damaged the Blood, Yin or Nutritive levels of the Heart and Lung causing the patient to:
"desire food yet does not want to eat, wants to lie down but is unable to lie down, wants to walk but is unable to walk... They may feel cold but have no chills, or they feel hot but have no fever... The various medicines are ineffective and when they take medicine there is intense vomiting and diarrhoea. They are as if possessed."In modern practice it generally refers to emotional disorders accompanied by fatigue, restlessness and hypersensitivity. "They are as if possessed" implies that they are not and so this disorder is different from various Gui syndromes, but they seem to be controlled by their external factors because they react to everything. Being in a constant state of reaction, they appear to have little volition of their own.
