In brief: Forget it

No home remedies work for this.
None of the creams are worth the money. Prescription pills are very effective but only if taken at the prodrome. Best is valacyclovir 2 grams at once when the first tingling warns of an impending attack. May still help if taken at first appearance of the sore. After the first 12-24 hours it does not matter what you do. Protect from sun (uv) and control of fever redu.
