Echinacea for shingles- get a 1 or 2 oz extract tincture and take the whole thing throughout 1 day, you can't overdose on it. This worked for me and three others, I noticed changes before the day was over, and by the next day, all that had to happen was to heal the damage done by the shingles.
I had a nasty case several years back and if it even starts to appear I take an herbal supplement with echinacea that knocks it out of the park before it becomes a nuisance :)
