Spells (3e)

Heal enables the character to channel positive energy into a creature to wipe away disease and injury. It completely cures all diseases, blindness, deafness, hit point damage, and all temporary ability damage. It neutralizes poisons in the subject’s system. so that no additional damage or effects are suffered. It offsets a feeblemind spell. It cures those mental disorders caused by spells or injury to the brain. Only a single application of the spell is needed to simultaneously achieve all these effects.

Heal does not remove negative levels, restore permanently drained levels, or restore permanently drained ability scores.

If used against an undead creature, heal acts like harm.
