Cold sores are often caused by the type 1 herpes simplex virus and appear as pinkish, fluid-filled blisters usually found around the edges of the mouth. Most cold sores develop when another virus, such as the common cold, enters the body. The immune system is lower during sickness, allowing the cold sores to form. When choosing herbal treatment for cold sores, it is often best to combine several remedies. The patient must also consider the side effects of each herbal treatment, and may need to experiment to see which combination of treatments works best.
Many cold sore infections begin as a mild tingling around the edges, or along the corners, of the mouth. It is often best to begin treatment as soon as this tingling begins, especially for those using lemon balm or St. John’s Wort. Research has shown that herbal treatment for cold sores is often most effective when applied at the first signs of infection. Both herbs may be taken internally and applied topically. Lemon balm should typically be used fresh because its oils are the most potent when it smells lemony and strong.
St. John’s Wort may be taken as an herbal supplement capsule, or mixed into a paste with aloe vera gel and applied directly to the affected area. Fresh lemon balm may be brewed into tea or applied as a paste, like the St. John’s Wort. These herbs may also be combined. Both of these treatments may work best for those with sensitive skin or irritable digestive systems because they’re relatively gentle. They may also help boost the immune system, reducing the chance of cold sores appearing in the future.
A slightly stronger remedy may be necessary for cold sores that have already formed. Licorice root, peppermint oil, and echinacea are all relatively strong, antiviral herbs that may help shrink and alleviate manifested cold sores. All of these herbs may be applied topically or taken internally, but they may have unpleasant side effects. Patients should consider these side effects before deciding how to take any herbal treatment for cold sores.
Licorice root oil or strong licorice root tea may be applied to cold sores several times a day with a cotton ball. The tea may also be ingested, but could cause diarrhea if taken in large quantities. Most licorice root teas have a laxative affect, so topical application may be the best option for those with digestive problems. The same may hold true for peppermint oil and echinacea. They are both strong astringents when applied topically, but could cause an upset stomach if ingested regularly. These three treatments should be used individually, not together. Ideally, they should also be administered under the advice of a health care professional or a professional herbalist.
