I am having some trouble determining if a healing belt from the Magic Item Compendium (p.110) can be used to heal oneself as well as others or if it is only able to be used to heal others.
Based on the fact that it seems to indicate it works as a spell with a range of "touch" I am thinking it cannot be used to heal oneself.
The item description reads as follows:
Activation: — and standard (command)
This broad leather belt is studded with three moonstones. While wearing a healing belt, you gain a +2 competence bonus on Heal checks. This is a continuous effect and requires no activation. In addition, the belt has 3 charges, which are renewed each day at dawn. Spending 1 or more charges allows you to channel positive energy and heal damage with a touch. (You can also use this ability to harm undead, dealing them an equivalent amount of damage instead.)
