The rings worn by Green Lanterns are incredibly powerful, granting a wide range of abilities to the wearer, including the ability to create green-colored objects known as constructs. The Green Lantern can then control the construct via telekinesis, guiding it to attack, defend, or remain stationary. However, one power that's not granted with the ring is self-healing.
The ring can conjure a green shield to protect the Green Lantern, but it can not heal injuries. In Hal Jordan's story arc, Abin Sur turned down an offer to obtain the ring because the right couldn't heal his injuries. Hal Jordan later broke his arm and couldn't use the ring to heal it. The best thing he could do was conjure a green cast to hold the broken bones in place while his body did the healing.
