Loquat pit is not edible. If you swallow loquat seeds, cyanosides will be hydrolyzed by saliva when chewing, releasing highly toxic hydrocyanic acid. Under the action of enzymes, hydrocyanic acid can be decomposed and released, leading to hydrocyanic acid poisoning. Hydrocyanic acid is absorbed in tissues and cells and combined with iron-containing respiratory enzymes, resulting in hypoxia, which in turn damages the functions of respiratory and vascular movement centers, and even leads to respiratory paralysis and death in severe cases. In an emergency, it's best to go to the hospital and be rescued by a doctor.
Finally, I still want to remind you that loquat seeds are not edible. After eating loquat, it must be preserved to prevent children from eating it by mistake.
