Synopsis

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

Himalayan salt is used to support or treat cold sores primarily based on traditional and anecdotal practices, not robust scientific evidence. Historically, salt in general has been used in folk remedies for its presumed ability to "dry out" sores and create an environment less favorable for microbial growth. Some people apply salt directly to cold sores, believing it speeds up healing or reduces pain. However, there is no direct scientific validation, particularly for Himalayan salt, which is chemically similar to regular table salt except for trace minerals.

Scientific research on salt’s effect on Herpes simplex virus (the cause of cold sores) is lacking. While salt’s dehydrating and antiseptic properties might marginally reduce secondary infection risk due to its hyperosmotic effect, there are no clinical trials or studies demonstrating efficacy or safety for salt—Himalayan or otherwise—in the treatment of cold sores. Medical guidelines do not recommend salt as a treatment. In fact, applying salt directly to an open sore could increase irritation and pain. Thus, the use of Himalayan salt for cold sores remains a traditional remedy with minimal supporting evidence, meriting a low evidence rating.
