The Bezoar is an immunity accessory that grants the player immunity to the Poisoned debuff. It has a 1/100 (1%) / 1/50 (2%) chance to drop from Hornets, Moss Hornets, and Toxic Sludges.

It is one of the ingredients required to make the Medicated Bandage, which is a crafting material required to make the Ankh Charm, an accessory further required to make the Ankh Shield.

It is most easily acquired before Hardmode, when the Underground Jungle is still relatively safe.
The Poisoned status effect can be exceptionally deadly early on in higher difficulties, especially Master Mode where it sometimes lasts over 40 seconds. The Bezoar takes up a valuable accessory slot that the player may not have to spare, though. Instead, you can simply keep the Bezoar in your inventory, and briefly put it on to cleanse yourself of the status effect before returning it to your inventory, allowing you to remove the poison without having to wear it all the time.

It is one of the (Desktop, Console and Mobile versions) six / (Old-gen console and 3DS versions) four components of the Ankh Shield that can be obtained in pre-Hardmode, the others being the Obsidian Skull, Cobalt Shield, Nazar, (Desktop, Console and Mobile versions) Adhesive Bandage, and (Desktop, Console and Mobile versions) Megaphone.
A bezoar is a lump of mass trapped in the digestive system, historically believed to have antibiotic and poison-curing effects.
Despite Venom also being poison, the Bezoar does not prevent the Venom debuff.
- In the Desktop version, Console version, and Mobile version, Venom is renamed to Acid Venom, implying that it damages by corrosion or degradation instead of disruption of the system.
