for what i know, healing is only one of the possible usage of the luminous element, which the use of the element is not restricted to only this aspect. For example, toward the end of web version SAO, some used luminous element to form a defend shield.

Edit: seem like it is the way how the original page write as...

but i think the 光素 name there is just a descriptive name given in japanese about what the element is,thus i think it might not be that necessary..
