Forged keel: The keel is a fossil of the bones of ancient mammals such as elephants, rhinoceroses and three-toed horses. Take the brushed keel, burn it red in smokeless fire or crucible, take it out, let it cool, and crush it to get the calcined keel. Calcined keel has the functions of calming nerves, arresting sweating, solidifying essence, stopping bleeding, astringing intestines, promoting granulation and healing sores. It is used to treat epilepsy, palpitation, amnesia, insomnia and dreaminess, spontaneous sweating and night sweats, nocturnal emission, emesis and hematochezia, metrorrhagia and leukorrhagia, diarrhea and proctoptosis, and chronic ulcer.

Calcined Oyster: Oyster contains 80% ~ 95% of calcium carbonate and calcium phosphate. The China Pharmacopoeia 1995 edition stipulates that oyster should be "cleaned, and calcined by illumination to crisp". Calcined Oyster: It has a strong astringent and acid-removing effect, and can be used to treat stomachache and gastric acid.
