Gu (a type of venomous poison or parasitic disease) refers to a toxic substance deliberately created and accumulated by humans. It is typically made by collecting various insects and snakes, placing them in porcelain vessels, and allowing them to devour each other until only one survives. This remaining creature is called "Gu." It is used to harm others, usually entering the body through food and drink. Once infected, symptoms include chest oppression and abdominal pain; if it erodes the five Zang organs completely, death ensues. The condition varies in urgency: acute cases may lead to death within ten days, while chronic cases may drag on for months or years, with the pathogen wandering inside the abdomen. Patients often suffer from physical weakness and fatigue, heavy sensations in the joints, and upon onset, dryness and pain in the heart and abdomen. Even ingested food can transform into Gu toxin, gradually eroding the Zang and Fu organs until death. After death, the disease spreads as Zhu (infectious wasting disease), infecting others nearby, hence termed Gu Du (Gu Poison).
