ColdSore-FX is a new topical product promoted for cold sores. Is it worth considering?
ColdSore-FX is an ointment containing propolis 3%. Propolis is a resin from poplar and conifer buds that bees use to maintain their hives.
Propolis has been shown to have antiviral effects against herpes simplex type 2 and can improve symptoms of genital herpes.
At least, in the test tube, it also has activity against the virus that causes cold sores, herpes simplex type 1.
However, according to the experts at the Natural Medicines Comprehensive Database, a group providing unbiased, evidence-based information on complementary, alternative, and integrative therapies, “So far there is no reliable clinical evidence that it improves healing of cold sores.”
Until there’s evidence that in actual patients this product is both safe and effective, I won’t be recommending it.
