Bezoars were important objects in cabinets of curiosity and natural history collections, mainly for their use in early modern pharmacy and the study of animal health.The Merck Manual of Diagnosis and Therapy notes that consumption of unripened persimmons has been identified as the main cause of epidemics of intestinal bezoars, and that up to 90 percent of bezoars that occur from excessive consumption require surgery for removal.A 2013 review of three databases identified 24 publications presenting 46 patients treated with Coca-Cola for phytobezoars. The cola was administered in doses of 500 ml (18 imp fl oz; 17 US fl oz) to up to 3,000 ml (110 imp fl oz; 100 US fl oz) over 24 hours, orally or by gastric lavage. A total of 91.3% of patients had complete resolution after treatment with Coca-Cola: 50% after a single treatment, with others requiring the cola plus endoscopic removal. Doctors resorted to surgical removal in four cases. See also

A cook in the Kings court was sentenced to death, and chose to be poisoned. Paré administered the bezoar stone to the cook, but it had no effect, and the cook died in agony seven hours after taking the poison, proving that contrary to popular belief, the bezoar could not cure all poisons.Modern examinations of the properties of bezoars by Gustaf Arrhenius and Andrew A. Benson of the Scripps Institution of Oceanography show that when bezoars are immersed in an arsenic-laced solution, they can remove the poison. The toxic compounds in arsenic are arsenate and arsenite; each is acted upon differently by the bezoars: arsenate is removed by being exchanged for phosphate in brushite found in the stones, while arsenite is bound to sulfur compounds in the protein of degraded hair, which is a key component in bezoars.A famous case in the common law of England (Chandelor v Lopus, 79 Eng Rep. 3, Cro. Jac. 4, Eng. Ct. Exch. 1603) announced the rule of caveat emptor ("let the buyer beware") if the goods they purchased are not in fact genuine and effective. The case concerned a purchaser who sued for the return of the purchase price of an allegedly fraudulent bezoar.
