What is quinide and what does it do to your body?

Answer 1

Quinide is the common name for the chemical 4-Caffeoyl-1,5-quinide. It's part of the chemical family known as Cinnamoylquinides.

Quinide forms at high temperatures from natural chlorogenic acids found in coffee beans. Once inside your body, it binds to and inhibits the μ-opioid receptor and can cause symptoms such as analgesia, sedation, hypotention, itching, nausia, euphoria, decreased respiration, constricted pupils, and constipation. However, at the concentrations found in coffee, the effects of the drug are rarely, if ever, noticed.
