Can you apply Extend Spell to it? If you can, that'll give you a 2nd level spell that heals 22-30 damage and a 4th level spell that heals 60-100... Does the 1st level vigor spell meet the criteria for being placed in a wand? If it does, it blows wands of CLW out of the water in the healing-between-fights department. 550 points of healing vs. an average of 275.
