Arcania of Legend: Blood Magic covers temporary enchantments, particularly consumable enchantments such as potions. You could use those rules, perhaps in combination with the ones from Arms of Legend, to work something out for yourself.
However with the rules from Arcania of Legend: Blood Magic you can now create potions of Treat Wounds, Regenerate Limb and Restoration, or any of the other healing and restoration spells going from Legend and other sourcebooks.
