The Five Corpse Disorders are five separate patterns believed to be caused by the dead. It is different from the Three Corpse Possession Disorder which was a single condition caused by three innate parasitic entities. The common theme seems to be that they were fatal and after death, the corpse of the victim would return to infect their relatives. Modern interpretations consider these disorders to refer to diseases such as tuberculosis that were infectious to those living in close contact with the patient but have gradual onset so that symptoms would often only appear after the initial patient's death and lead to the consumption and eventual death of the family members.
Lu and Wilcox's (2014) commentary to Wang Zhizhong's Nourishing Life with Acupuncture and Moxibustion describe them as:
Herbal treatments often included highly toxic ingredients such as Eight Toxins Red Pills, reported by Zhen Liyan, which contained arsenic, mercury, aconite, false hellebore, croton seed and centipede. However, he also recalls Ren Dong Teng being effective for Transmitted Corpse Consumption (傳屍癆 Chuan Shi Liao), another name for this type of condition.
