Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Vinegar, particularly apple cider vinegar, is often recommended in folk and traditional remedies for the treatment of cold sores (herpes labialis). The basis for this traditional use stems from vinegar’s natural acidity and its known antibacterial and possibly antiviral properties in vitro. Historically, people have applied vinegar topically to cold sores with the belief that its acidic environment may inhibit the growth of pathogens or hasten the drying and healing of the sore.

However, there is very limited scientific evidence supporting the use of vinegar for cold sores. Most available data on vinegar’s antimicrobial effects pertain to bacteria rather than viruses like herpes simplex virus (HSV-1), which is responsible for cold sores. There are no well-designed clinical trials or laboratory studies specifically evaluating the efficacy or safety of vinegar for cold sores in humans. Furthermore, topical application of vinegar can cause skin irritation, burning, or even chemical burns, especially on broken or sensitive skin.

In summary, while vinegar’s use for cold sores is rooted in traditional practices, this application is not substantiated by scientific research, and potential risks may outweigh any unproven benefits.
