Essential Oils
Numerous essential oils, which are concentrated oils made of plant chemicals, have been shown in studies to have inhibitory effects on the herpes simplex virus, which is responsible for cold sores. Despite the paucity of research, a 2015 study discovered that several essential oils might hinder or stop the herpes virus from replicating, hence assisting in the healing and prevention of cold sores.
Most of the study on essential oils and HSV-1 is sadly outdated. For example, a lab study from 2003 demonstrates that peppermint oil efficiently combes the HSV-1 and herpes simplex virus type 2, while a study from 2001 indicated that tea tree oil exhibits some antiviral activities that may help fight off the herpes simplex virus (HSV-2).
According to a 2007 study, the essential oils of ginger, thyme, hyssop, and sandalwood could successfully treat drug-resistant strains of the virus. Notably, the data may be anecdotal, and these studies have limitations. Both investigations used monkey herpes cells rather than human ones.
In a test tube or culture dish, they were also carried out in vitro. The degree of these oils’ antiviral activity in humans requires more study.
