The healing device of the Goa'uld is a mechanism consisting of a large red crystal emitter which can be slid on one's hand. Like other Goa'uld hand devices, the healing device can only be used by people who have Naquadah in their blood such as Goa'uld, Tok'ra, and former hosts. Its operation appears to be similar to the Goa'uld ribbon device, as it seems to require strong desire or emotion from the user to activate. It is also possible to make the device light up but not work, as Nirrti did when she bluffed trying to heal Cronus with the device. The device is capable of healing Staff weapon wounds, several diseases and even near fatal injuries. It is however not as powerful as a Sarcophagus and can't revive the dead.
