Commentary states: When willpower is weak and the heart-mind is empty, with the spirit losing its residence, one may be offended by evil qi, causing sudden severe pain in the heart and abdomen, stupor and confusion resembling death, with no awareness. This is called Zhong E (Sudden Attack by Evil), also known as Zu Wu (Sudden Offense). It occurs because yin and yang are blocked, the qi mechanism is reversed, communication between upper and lower parts is obstructed, and yang qi is scattered, leading to loss of consciousness. If qi returns, life is preserved; if not, death ensues. If prolonged and unhealed, it transforms into Zhu disease (a type of infectious or lingering illness).

For treating Sudden Attack by Evil Qi, Guest Offense, Five Corpses entering the abdomen, Ghost Stabbing and Ghost Pushing, as well as Gu Poison Attack, hematemesis, hematochezia, sudden heart and abdominal pain, abdominal fullness with cold-heat toxic diseases, use the Beiji San (Emergency Rescue Powder) formula:

Take the nine ingredients above. Process the Croton Seed separately into a paste. Grind the remaining ingredients into fine powder. Mix the Croton paste with the powder thoroughly. Store in a porcelain vessel, seal tightly to prevent leakage of qi. For emergencies, administer orally with water, approximately "yi zi" (a small measure), increasing up to half a "zhan bi". Reduce dosage for elderly and children. If the pathology is in the head, nasal bleeding may occur; if above the diaphragm, vomiting may occur; if below the diaphragm, diarrhea may occur; if in the limbs, sweating may occur leading to recovery.
