In brief: Few

Most over the counter remedies are simply palliative.
The acute phase lasts 10-14 days. Prescription meds such as Famvir (famciclovir) or Acyclovir given topically and orally can decrease the length of time of the acute flair up.

In brief: No good home remedy

Over-the-counter abreva plus Hydrocortisone 1% cream may help.
Some other o-t-c lip balms (may have menthol) help a little with the symptoms. Cold sores on the lips or near the lips, are usually caused by herpes virus. They start as a raised reddish area, then form a cluster of tiny blisters, which break open soon, leaving a sore (ulcer) to heal up over a week. Younger babies should see a doctor.
