Healing springs can restore hitpoints you have lost (e.g., if you have 14/50, it can give you up to the 50), but the only way to add to the hitpoints you already have (so, if you have 50 and want to raise it to 51) is to train for endurance, do faerie quests ( the Dark Faerie and Faerie Queen are the faeries who give more hitpoints), do kitchen quests, eat certain neggs, use the lab ray, or visit the Coltzan's Shrine (he too occasionally gives more hps).
Actually, the Healing Springs can restore more than your maximum HP, but you can only use them in the first round of a fight in the battledome. After that, they disappear and you're back to max HP only.
