@burcidi-- I'm guessing that some of them will work because as far as I know, shingles and herpes are in the same category of viruses. But it's still better to seek treatments specifically for shingles blisters.
Some home remedies might help though, such as treating with salt or essential oils with antiviral properties like eucalyptus oil and tea tree oil. But make sure to dilute these oils before you use them.
I've also heard that applying vitamin E oil or apple cider vinegar on the blisters quickens healing. I haven't tried them personally though.
One easy treatment I can vouch for is multi-vitamins. A strong immune system is very important for beating viral infections.
