* [[Sage]] : when applied as a cream containing sage and rhubarb. Applying a cream containing sage and rhubarb (Rheum officinale and Rheum palmatum) to cold sores may be about as effective as acyclovir (Zovirax) cream. Acyclovir cream heals the cold sores in about 6 days; it takes the sage and rhubarb cream about 7 days to heal them. Sage and rhubarb together work faster than sage alone.
