Honey is a sweet fluid made by honeybees from the nectar of flowers. It is generally safe, but there have been reports of certain toxic types of honey made from plants from the Rhododendron genus and others.
Honey is easy for the body to absorb and use. It contains about 70-80 percent sugar. The rest is water, minerals, and some protein, acids, and other substances. Honey has been used for wounds, skin problems, and various diseases of the stomach and intestines.
The antibacterial effects of honey are well-known. Research has been done on the role of honey in long-term wound management, as well as the treatment of ulcers, burns, Fournier's gangrene (a life-threatening bacterial infection), and diabetes. However, more high-quality studies are needed to make firm conclusions on the use of honey.
These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.
There is a lack of evidence on the use of honey for the treatment of allergy symptoms of the eyes and nose. Results are conflicting, with some studies reporting a lack of benefit, while others suggest that honey may reduce redness, swelling, and pus discharge. More high-quality research is needed before a firm conclusion may be made.
Honey has been used to heal burns and prevent infection for thousands of years. It has been used as a wound cover in studies on treating burns and is found in many licensed medical products. There is evidence to support the benefit of honey in healing and sterilizing infected wounds. Promising results show that honey may reduce burn-healing time. However, many studies were conducted by the same researchers, who compared honey dressings to other treatments such as potato. More evidence is needed in this area.
Honey used together with chemotherapy may be a promising and inexpensive way to prevent low white blood cell count caused by chemotherapy. However, more studies are needed before a conclusion may be made.
Honey may be an inexpensive treatment for cough in children with upper respiratory tract infections (URIs). Although honey may have few side effects, there are conflicting reports. The use of honey may cause cavities, hyperactivity, sleep problems, bacterial infection, or effects on the heart. High-quality research is needed before a conclusion may be made.
Honey has been proposed as a potential sugar substitute. Studies report that honey may lower blood sugar levels, although conflicting results have been found. Further high-quality studies are needed before a conclusion may be made.
Honey applied to the skin may be a cost-effective treatment for diabetic foot ulcers, due to its antibacterial and tissue-healing properties. However, further high-quality research is needed before a conclusion may be made.
Research suggests that honey may lack significant effect on exercise performance. Further research is needed before a conclusion may be made.
Honey has been studied for the treatment of Fournier's gangrene. However, it is often used with antibiotics, and the effects of honey alone are unclear. More research in this area is needed to reach a firm conclusion.
Honey has been studied in children with the stomach flu, with limited benefit reported. Evidence is limited and more research is needed before a conclusion may be made.
Early evidence suggests that honey may help treat plaque and gum disease. More studies are needed to support these findings.
Early studies report that a combination therapy containing honey may help reduce bleeding, pain and itching in people with hemorrhoids. However, more high-quality research is needed before a conclusion may be made.
Early research has found that honey may be effective in treating herpes of the mouth (cold sores and fever blisters), but not herpes of the genitals. More research is needed in this area to draw a conclusion.
Early study suggests that honey may benefit people who have high blood pressure. However, more studies are necessary to confirm these findings.
Evidence is lacking to support the use of honey for high cholesterol. More studies are needed before a conclusion may be made.
Evidence is mixed on the use of honey to treat catheter-related infections. More high-quality studies are needed before a conclusion may be made.
Early research has found promising results with a honey-containing combination treatment for infertility. However, further research is needed before a conclusion may be made.
Early research suggests that honey barrier cream may help treat itching and increase comfort. However, more studies are needed before a conclusion may be made.
Studies have found little to no benefit of honey dressings on leg ulcers. More research is needed to determine the effects of honey on the treatment of ulcers.
Early evidence has found positive effects of honey in terms of increasing weight and the passage of food through the stomach. However, more research is needed before a conclusion may be made.
Early research found that tualang honey may help some aspects of memory in women undergoing menopause. Further research is needed before a conclusion may be made.
Honey treatment appears to be promising for preventing mouth sores caused by radiation treatment in people with cancer. However, results are conflicting. Better quality studies are needed before a firm conclusion may be made.
Early studies found a lack of strong evidence to support the use of honey for parasite infections. Higher quality research is needed before a conclusion may be made.
Early research found a lack of benefit of honey for the treatment of pneumonia. Further studies are needed before a conclusion may be made.
Early research showed a lack of effect of honey in people with fungal-induced sinus infections. Further study is needed before a firm conclusion may be made.
Currently, there is a lack of evidence on the use of honey for the treatment of split-thickness skin graft. Although early research suggests a shorter healing time, more studies are needed to make a firm conclusion.
There is limited evidence to support the use of honey in the treatment of dandruff. More research is needed before a conclusion may be made.
Honey used together with antibiotics and acetaminophen may help improve healing after surgery. However, more research is needed to confirm these promising early results.
Honey has been studied for various types of ulcers, including breast ulcers. Honey may reduce pain, odor, and wound size. However, more studies are needed before a firm conclusion may be made.
Honey has been commonly used for wound management and the promotion of healing. It has also been used to treat antibiotic-resistant bacteria. Much research has been done on various types of honey, including medical grade honey, on different types of wounds. These types of wounds include long-term ulcers, wounds after surgery, and burns. More high-quality research is needed.

Side Effects and Warnings
Honey is likely safe when taken by mouth in food amounts, or when recommended doses are used. Honey is possibly safe when applied to the skin.
Honey may cause abnormal or absent heart rhythms, blurred vision, changes in taste, changes in white blood cell count, chest pain, diarrhea, double vision, drowsiness, faintness, fatigue, feeling of burning or tingling on the skin, fever, heart attack, honey intoxication (sweating or weakness when honey produced from Rhododendron plants is used), hyperactivity, impaired consciousness, increased saliva, lung problems, mild paralysis, musculoskeletal problems, minor scarring, nausea, nervousness, pain, seizures, sleep problems, sweating, tooth decay, upset stomach, urinary tract infections, vomiting, weight loss, and wound dryness or infection.
Honey may affect blood sugar levels. Caution is advised in people with diabetes or low blood sugar, and in those taking drugs, herbs, or supplements that affect blood sugar. Blood sugar levels may need to be monitored by a qualified healthcare professional, including a pharmacist, and medication adjustments may be necessary.
Honey may increase the risk of bleeding. Caution is advised in people with bleeding disorders or taking drugs that may increase the risk of bleeding. Dosing adjustments may be necessary.
Honey may cause low blood pressure. Caution is advised in people taking drugs or herbs and supplements that lower blood pressure.
Honey may interfere with the way the body processes certain drugs using the liver's "cytochrome P450" enzyme system.
Use cautiously when the origin of the honey is unknown, due to possible toxicity.
Use cautiously in people who have heart conditions, nervous system disorders, and stomach or intestine conditions.
Use cautiously in people who are taking antibiotics, heart medications, nervous system agents, stomach or intestine medications, and weight loss agents.
Avoid in children under 12 months of age.
Avoid in people with known allergy or sensitivity to celery, pollen, or other bee-related allergies, and when honey made from plants in the Rhododendron genus is used, due to toxicity.
Note: Honey that is contaminated with the bacteria Clostridium botulinum may cause poisoning in infants and young children. However, this is not a danger for older children and adults.
Pregnancy and Breastfeeding
There is a lack of scientific evidence on the use of honey during pregnancy or breastfeeding. Honey may contain contaminants that may be harmful to pregnant or breastfeeding women, or to unborn babies.
Honey may increase the risk of bleeding when taken with drugs that increase the risk of bleeding. Some examples include aspirin, anticoagulants ("blood thinners") such as warfarin (Coumadin®) or heparin, anti-platelet drugs such as clopidogrel (Plavix®), and non-steroidal anti-inflammatory drugs such as ibuprofen (Motrin®, Advil®) or naproxen (Naprosyn®, Aleve®).
Honey may lower blood sugar levels. Caution is advised when using medications that may also lower blood sugar. People taking drugs for diabetes by mouth or insulin should be monitored closely by a qualified healthcare professional, including a pharmacist. Medication adjustments may be necessary.
Honey may cause low blood pressure. Caution is advised in people taking drugs that lower blood pressure.
Honey may interfere with the way the body processes certain drugs using the liver's "cytochrome P450" enzyme system. As a result, the levels of these drugs may be altered in the blood, and may cause altered effects or potentially serious adverse reactions. People using any medications should check the package insert, and speak with a qualified healthcare professional, including a pharmacist, about possible interactions.
Honey may also interact with agents taken for the blood, agents taken for the heart, agents taken for the nervous system, agents taken for the skin, agents taken for the stomach or intestines, agents taken for the urinary tract, antibiotics, anticancer agents, antifungal agents, anti-inflammatory agents, anti-seizure agents, cholesterol-lowering agents, dental agents, ethanol, weight loss agents, and wound-healing agents.
Interactions with Herbs and Dietary Supplements
Honey may increase the risk of bleeding when taken with herbs and supplements that are believed to increase the risk of bleeding. Multiple cases of bleeding have been reported with the use of Ginkgo biloba, and fewer cases with garlic and saw palmetto. Numerous other agents may theoretically increase the risk of bleeding, although this has not been proven in most cases.
Honey may interfere with the way the body processes certain herbs or supplements using the liver's "cytochrome P450" enzyme system. As a result, the levels of other herbs or supplements may be altered in the blood. It may also alter the effects that other herbs or supplements possibly have on the P450 system.
Honey may lower blood sugar levels. Caution is advised when using herbs or supplements that may also lower blood sugar. Blood glucose levels may require monitoring, and doses may need adjustment.
Honey may cause low blood pressure. Caution is advised in people taking herbs or supplements that lower blood pressure.
Honey may also interact with antibacterials, anticancer herbs and supplements, antifungal herbs and supplements, anti-inflammatory herbs and supplements, antioxidants, anti-seizure herbs and supplements, cholesterol-lowering herbs and supplements, dental herbs and supplements, herbs and supplements taken for the blood, herbs and supplements taken for the heart, herbs and supplements taken for the nervous system, herbs and supplements taken for the skin, herbs and supplements taken for the stomach or intestines, herbs and supplements taken for the urinary tract, weight loss herbs and supplements, and wound-healing herbs and supplements.
