Carpal tunnel release. Carpal tunnel release is surgery to treat carpal tunnel syndrome. Carpal tunnel syndrome is pain and weakness in the hand that is caused by pressure on the median nerve in the wrist. The median nerve and the tendons that flex (or curl) your fingers go through a passage called the carpal tunnel in your wrist. This tunnel is narrow, so any swelling can pinch the nerve and cause pain. A thick ligament (tissue) just under your skin (the carpal ligament) makes up the top of this tunnel.

The oils found in cinnamon bark are thought to reduce spasms, reduce gas (flatulence), and stimulate the appetite. Cinnamon might also increase blood flow. Cinnamon bark also contains a chemical that might work like insulin to lower blood sugar. However, these effects are thought to be fairly weak. There are also ingredients in cinnamon bark called tannins that might help wounds by acting as an astringent, and also prevent diarrhea.
