Zoe,
I do eat food with arginine but very limited intake. Cashew is one big culprit
for me as well as almond. i can take pistachio but an ounce in a day only.
If you google foods with arginine you will find a list of foods containing it.
I haven't had an outbreak of my cold sore since i treated it with
micro-electricity gadget and combination of 50-50 CS and Swedish Bitters and to
it I then added an eye dropperful of DMSO then i added an eye dropper of
tincture (using DMSO) of black walnut hull. Once i feel the itch i put that
mix and it disappears. See if this can help you also. Just buy the smallest
Swedish Bitters from Swanson as that is from Germany. Don't even think of
drinking the mix - swedish bitters has senna and that raises blood pressure.
