If you suspect that you're going to need in combat healing in a fight (remember, as written, drinking a potion costs your standard action and provokes of opportunity), you can always spontaneously turn one of your 4th level spell slots into Summon Nature's Ally, and get a unicorn. Those heal more than the equivalent heal spell, and come with circle of prot from evil, meaning it can keep the injured char a little safer.
Your allowed source books would be helpful.
There are some pretty neat tricks you can pull with your feats as a druid. Spell Focus: Conjuration & Augment Summoning are helpful for getting tougher summons. As a druid, you can summon really awesome grapplers.
Ashbound, from Eberron Campaign Setting, doubles the duration of all your SNA spells, and gives them +3 attack/+3 damage. I highly recommend it, if you plan on summoning and have access to it.
You can also try out Lesser Aasimar. Give up Outsider type, lose the level adjustment.
