Herpes simplex virus (HSV) infections are very common worldwide. HSV-1 (usually known as a cold sore) is transmitted through kissing or sharing drinking utensils, and HSV-2 (usually known as genital herpes) through sexual contact. You may be infected and not show symptoms for a long time. Often symptoms are triggered by exposure to the sun, fever, menstruation, emotional stress, a weakened immune system, or an illness.
There is not cure for herpes, and once you have it, it is likely to recur; however, some people may have one outbreak and then never have another one. In between herpes outbreaks, the virus lies dormant (as if it is hibernating or sleeping) in nerve cells.
While exposure to HSV-1 is extremely common – as many as 90% of American adults have been exposed to the virus – and there is no stigma to having a cold sore, HSV-2 or genital herpes can cause embarrassment. Although there is no cure for genital herpes, an infected person can take steps to preventing spreading the disease and can continue to have a sex life.
While most herpes infections do not cause serious complications, infections in infants and in people with weakened immune systems or herpes infections that affect the eyes can be life-threatening.
Herpes cannot be cured, so the goals of treatment are to reduce the number of outbreaks and to lessen symptoms when you do have an outbreak.
Cold sores usually go away by themselves in no more than 1 to 2 weeks. Using medications may shorten the outbreak and decrease discomfort.
Antiviral medications for genital herpes can reduce outbreaks and help speed recovery when an outbreak does occur. They can also lessen the chances of spreading the virus.
Coping with the emotional and social aspects of having genital herpes is part of treatment. Relaxation techniques and support groups can help.
Lifestyle
For cold sores, applying either heat or cold to blisters may help relieve pain. Try ice or warm compresses.
For genital herpes, wear cotton underwear and avoid tight fitting clothes as they can restrict air circulation and slow the healing of lesions.
Be sure to tell your partner or potential partner that you have herpes.
Medications
Antiviral medicines — may help shorten the duration of a herpes outbreak and suppress recurring outbreaks. For genital herpes, there are two types of therapy: episodic and suppressive. With episodic therapy, you take medication at the first sign of an outbreak and for several days to shorten the duration or prevent a full outbreak. With suppressive therapy, you may take medication daily to keep outbreaks from occurring. Antiviral medications include:
- Acyclovir (Zovirax)
- Famciclovir (Famvir)
- Valacyclovir (Valtrex)
Topical medications (for oral herpes) — include the antiviral cream Penciclovir (Denavir) and an over-the-counter cream, docosanol (Abreva).
Nutrition and Dietary Supplements
Because supplements may have side effects or interact with medications, they should be taken only under the supervision of a knowledgeable healthcare provider.
- Lysine (1 to 3 g per day) — Although not all studies agree, several studies suggest that lysine may help reduce the number of recurring outbreaks of cold sores and possibly genital herpes. Most of the studies have involved people with cold sores or with both cold sores and genital herpes. A few studies also suggest that lysine may help shorten the duration of an outbreak. The evidence is somewhat stronger for cold sores: the research to date is not entirely conclusive, lysine supplements have been used to help treat or prevent mouth and genital lesions caused by herpes. Taking lysine supplements or increasing lysine in your diet (from foods like fish, chicken, eggs, and potatoes) may speed recovery time and reduce the chance of recurrent breakouts of the herpes infection. If you have high cholesterol, heart disease, or high triglycerides (type of fatty material in the blood, generally measured when you have your cholesterol checked), it is best, at this point, not to use lysine because animal studies suggest that this supplement may raise cholesterol and triglyceride levels.
- Propolis — A resin made by bees, propolis is loaded with flavonoids (antioxidants that help fight infection and boost immune function). Test tube studies show it can stop HSV-1 and HSV-2 from reproducing. One small study of people with genital herpes compared an ointment made from propolis to Zovirax ointment. People using propolis saw the lesions heal faster than those using topical Zovirax. More studies are needed to say for sure whether propolis works.
- Zinc — In test tubes, zinc is effective against HSV-1 and HSV-2. In one small study in people, those who applied zinc oxide cream to cold sores saw them heal faster than those who applied a placebo cream.

Herbs
The use of herbs is a time-honored approach to strengthening the body and treating disease. Herbs, however, can trigger side effects and can interact with other herbs, supplements, or medications. For these reasons, herbs should be taken with care, under the supervision of a healthcare practitioner.
- Lemon balm (Melissa officinalis) — Several studies suggest that topical ointments containing lemon balm may help heal cold sores. In one study, for example, those who applied lemon balm cream to their lip sores saw a reduction in redness and swelling after two days.
- Aloe (Aloe vera) — Preliminary evidence suggests that aloe gel used topically may improve the symptoms of genital herpes in men. In two studies, men who used the aloe vera cream (0.5% aloe) saw lesions heal faster than those who used a placebo cream. It isn't know whether aloe vera would also help heal cold sores.
- Rhubarb cream (Rheum palmatum) — In one Swiss study, a cream made from sage (Salvia officinalis) and rhubarb was as effective as Zovirax in healing cold sores. Sage by itself was not beneficial. More research is needed.
- Eleutherococcus or Siberian ginseng (Eleutherococcus senticosus/Acanthopanax senticosus) —Although not all studies agree, one 6-month study of 93 people with genital herpes found that Siberian ginseng reduced the frequency, severity, and duration of outbreaks. This herb should not be taken if you have high blood pressure, obstructive sleep apnea (repeated, prolonged periods when breathing stops while sleeping), narcolepsy (frequent day time sleeping), are pregnant or breastfeeding.
- Peppermint oil (Mentha x piperita ) — In test tubes, peppermint oil has stopped a number of viruses from reproducing, including herpes. However, it isn't known whether peppermint oil would have any effect on the herpes virus in humans.

Homeopathy
Although few studies have examined the effectiveness of specific homeopathic therapies, professional homeopaths may consider the remedies described below for the treatment of herpes based on their knowledge and experience. One study of 53 people with genital herpes did show that the majority had improvement in their symptoms and were less likely to have recurrent outbreaks when treated with homeopathy. Participants in this study were followed for up to 4 years.
Before prescribing a remedy, homeopaths take into account a person's constitutional type. A constitutional type is defined as a person's physical, emotional, and psychological makeup. An experienced homeopath assesses all of these factors when determining the most appropriate remedy for each individual.
For cold sores:
- Natrum muriaticum — for eruptions at the corners of the mouth that occur during periods of emotional stress and tend to worsen in the daytime
- Rhus toxicodendron — for eruptions consisting of many small blisters that itch intensely at night
- Mercurius — for children who drool and may have a fever
- Sepia — for outbreaks that do not improve with other homeopathic remedies; this remedy is most appropriate for individuals who tend to have a lack of energy and don't tolerate cold weather
For genital lesions:
- Graphites — for large, itchy lesions in individuals who are overweight
- Natrum muriaticum — for eruptions that occur during periods of emotional stress and symptoms that tend to worsen in the daytime
- Petroleum — for lesions that spread to anus and thighs; symptoms tend to worsen in winter and improve in summer
- Sepia — for outbreaks that do not improve with other homeopathic remedies; this remedy is most appropriate for individuals who tend to have a lack of energy and don't tolerate cold weather
Mind/Body Medicine
- Support groups — Having genital herpes can impact your social and emotional life. In fact, if you have herpes, it is quite common to feel depressed, angry, and even guilty. Worrying about possible rejection by someone with whom you are hoping to become intimate is also typical. Joining a support group where members share experiences and problems can help relieve the stresses associated with having genital herpes. If you are in a committed relationship, seeing a couples' therapist with your partner may also be helpful.
- Relaxation techniques — Using relaxation techniques, such as yoga, guided imagery, and meditation, on a daily basis may help you feel better overall and cope with stresses related to having herpes.
- Self-hypnosis — Self-hypnosis using guided imagery may also help relieve stress. In one 6-week training program, participants with frequently recurring genital herpes were able to reduce outbreaks by nearly 50% and improve their mood, including reducing feelings of depression and anxiety.
- Other — Individual therapy with a psychiatrist, psychologist, or social worker; and techniques such as biofeedback can help reduce emotional symptoms associated with herpes.
Pregnancy
Herpes viruses can be transmitted to a newborn during vaginal delivery, especially if the mother has active lesions in the vagina at the time of delivery. Herpes infections in newborns can be life-threatening or cause disability. Delivery by cesarean section (C-section) will be recommended to avoid infecting the baby.
Special Populations
Newborns – herpes infections contracted during delivery from the mother can lead to meningitis, herpes infection in the blood, chronic skin infection, and may even be fatal.
You are more likely to have severe, frequent outbreaks and to experience complications from herpes if your immune system is suppressed from:
- HIV or AIDS
- Chemotherapy for cancer
- Long-term use of high doses of corticosteroids
- Medications that intentionally suppress the immune system
Warnings and Precautions
If you are diagnosed with genital herpes, you should be tested for other sexually transmitted diseases such as chlamydia and gonorrhea.
Prognosis and Complications
Herpes is a chronic, recurrent infection. The initial symptoms usually appear within 1 to 3 weeks of exposure to the virus and last 7 to 10 days (for cold sores) or 7 to 14 days (for genital lesions). Usually the number of outbreaks is greatest in the first year and higher for HSV-2 genital lesions than HSV-1 cold sores. Each year after that, the number of outbreaks usually goes down and they become less severe. But you can never completely get rid of the virus.
Complications of herpes include:
- Herpetic keratitis – herpes infection of the eye leading to scaring within the cornea and possible blindness
- Persistent herpes infection, without lesion-free periods
- Herpes infection in the esophagus
- Herpes infection of the liver which can lead to cirrhosis (liver failure)
- Encephalitis and/or meningitis (serious brain infections)
- Lung infection
- Eczema herpetiform – widespread herpes across the skin
