Overview
Tea tree oil is used for acne, infestation of the eyelashes with a type of mite (ocular demodicosis), toenail fungus (onychomycosis), and athlete's foot (Tinea pedis). It is also used for dandruff, lice, bad breath, and other conditions, but there is no good scientific evidence to support its other uses.
How does it work ?
Uses & Effectiveness ?
Possibly Effective for
- Acne. Applying a 5% tea tree oil gel appears to be as effective as 5% benzoyl peroxide (Oxy-5, Benzac AC, and others) for treating acne. Tea tree oil might work more slowly than benzoyl peroxide, but seems to be less irritating to facial skin. When applied twice daily for 45 days, tea tree oil reduces several acne symptoms, including acne severity. But tea tree oil might be less effective than another product prepared by fermenting a type of cypress with the probiotic Lactobacillus.
- Infestation of the eyelashes with a type of mite (ocular demodicosis). A number of early studies show that tea tree oil might cure this common eyelid infection and reduce the associated symptoms, including eyeinflammation and vision loss.
- Toenail fungus (onychomycosis). Applying 100% tea tree oil solution to the skin twice daily for 6 months can cure fungal toenail infection in about 18% of people who try it. It can also improve nail appearance and symptoms in about 56% of patients after 3 months and 60% of patients after 6 months of treatment. It seems to be comparable to twice daily application of clotrimazole 1% solution (Fungoid, Lotrimin, Lotrimin AF). Lower concentrations of tea tree oil do not seem to be as effective. For example, there is some evidence that a 5% tea tree oil cream applied three times daily for 2 months has no benefit.
- Athlete's foot (Tinea pedis). Topical application of a 10% tea tree oil cream works about as well as tolnaftate 1% cream (Genaspor, Tinactin, Ting, and others) for relieving symptoms of athlete's foot, including scaling, inflammation, itching, and burning. However, the 10% tea tree oil cream doesn't seem to cure the infection. However, applying a stronger tea tree oil solution (25% or 50%) appears to both relieve symptoms and clear up the infection in about half of people who try it for 4 weeks. However, 25% or 50% tea tree oil doesn't appear to be as effective for curing the infection as medications such as clotrimazole or terbinafine.
Insufficient Evidence for
- Overgrowth of bacteria in the vagina. Early research suggests that tea tree oil may benefit people with bacterial vaginosis.
- Dandruff. Early research suggests that applying a 5% tea tree oil shampoo three minutes daily for four weeks reduces scalp lesions, scalp itchiness, and greasiness in people with dandruff.
- Tooth plaque. Results from research examining the effects of tea tree oil on dental plaque are inconsistent. Some early research shows that brushing the teeth with a 2.5% tea tree oil gel twice daily for 8 weeks reduces gum bleeding but not plaque in people who have gingivitis caused by plaque. Also, using a mouthwash containing tea tree oil after a professional teeth cleaning does not seem to reduce plaque formation. However, rinsing with a specific product (Tebodont) containing tea tree oil and a chemical called xylitol seems to reduce plaque. Also, rinsing with another product that contains tea tree oil, clove, and holy basil seems to reduce plaque.
- Dry eye. Scrubbing the eyelid with a shampoo containing tea tree oil may reduce eye sensitivity and pain in people with dry eye after cataract surgery. These people are also using eye drops to reduce pain and swelling in the eyes.
- A mild form of gum disease (gingivitis). Results from research examining the effects of tea tree oil on gingivitis are inconsistent. Some early research shows that brushing the teeth with a 2.5% tea tree oil gel twice daily for eight weeks reduces gum bleeding but does not improve overall gum health in people who have gingivitis caused by plaque. However, rinsing with a specific product (Tebodont) containing tea tree oil and a chemical called xylitol seems to reduce gum inflammation. Also, rinsing with another product that contains tea tree oil, clove, and holy basil seems to reduce gum inflammation.
- Bad breath. Early research shows that adding tea tree oil to an essential oil mixture containing peppermint and lemon oils can reduce bad breath when used as part of a 3-minute oral cleaning.
- Hemorrhoids. Some early research suggests that applying a gel containing tea tree oil, hyaluronic acid, and methyl-sulfonyl-methane reduces symptoms of hemorrhoids, including pain, inflammation and itching, in children.
- Cold sores (herpes labialis). Research so far suggests that applying 6% tea tree oil gel five times daily does not improve cold sores.
- Male-pattern hair growth in women (hirsutism). Early research suggests that using a spray containing lavender oil and tea tree oil twice daily for 3 months slightly reduces hair growth in some areas in women with hirsutism.
- Lice. Early research suggests that tea tree oil might repel lice. Also, applying a combination of lavender and tea tree oil kills lice eggs and reduces the number of live lice. It is unclear if the effects are caused by the tea tree oil alone or the combination of lavender and tea tree oil.
- A difficult to treat infection caused by a bacteria that is resistant to many antibiotics (MRSA). Evidence about the effects of tea tree oil on MRSA infection is unclear. When compared to standard MRSA treatment alone, adding tea tree oil does not seem to improve overall MRSA clearance or prevent infection. Also, using a tea tree oil solution when cleaning wounds does not seem to improve MRSA clearance. However, an early study suggests that using a 4% tea tree oil nasal ointment plus a 5% tea tree oil body wash along with other standard treatments might have a small benefit. Tea tree oil does not seem to prevent MRSA infection.
- Allergic skin reactions to nickel. Early research suggests that undiluted tea tree oil may reduce the area and redness skin reactions in people who are allergic to contact with nickel. Also some early evidence suggests that applying diluted tea tree oil to the skin before nickel exposure reduces skin reactions in people allergic to nickel.
- Thrush. Because people with AIDS have a weak immune system, they sometimes come down with "opportunistic" infections such as thrush. There is some evidence that tea tree oil might be beneficial in patients with HIV/AIDS whose thrush does not respond to usual antifungal medications such as fluconazole. Swishing and expelling tea tree oil solution for 2-4 weeks seems to improve symptoms. There is also early evidence that using tea tree oil as part of an essential oil mixture might improve oral comfort in cancer patients. However, adding 1 mL of tea tree oil to a standard conditioner treatment does not reduce infections and inflammation in people with dentures.
- A sexually transmitted infection caused by Trichomonas vaginalis (trichomoniasis). Early research suggests that tea tree oil may be beneficial for people with a type of vaginal infection called trichomoniasis.
- Vaginal yeast infections. Early research suggests that tea tree oil may be beneficial for people with a type of vaginal infection called vaginal candidiasis.
- Water warts. Early research shows that applying a combination of tea tree oil and iodine to the skin of children for 30 days helps clear up skin bumps caused by a poxvirus better than just tea tree oil or iodine alone.
- A skin condition that causes redness on the face (rosacea).
- Congestion.
- Cough.
- Ear infection (otitis media).
- Preventing infections in cuts, abrasions, burns, insect bites and stings, and boils.
- Ringworm (Tinea corporis).
- Itchy skin infection caused by mites (scabies).
- Sore throat.
- Other conditions.
Side Effects
When applied to the skin: Tea tree oil is POSSIBLY SAFE for most people when put on the skin. It may cause skin irritation and swelling. In people with acne, it can sometimes cause skin dryness, itching, stinging, burning, and redness.
Special Precautions and Warnings
Children: Tea tree oil is LIKELY UNSAFE when taken by mouth. Do not give tea tree oil by mouth. As a general rule never give undiluted essential oils by mouth due to the possibility of serious side effects. Tree tea oil by mouth has caused serious side effects, including confusion, inability to walk, unsteadiness, rash, and coma.
Tea tree oil is POSSIBLY SAFE when applied to the skin. It may cause skin irritation and swelling. In people with acne, it can sometimes cause skin dryness, itching, stinging, burning, and redness. However, applying products to the skin that contain tea tree oil along with lavender oil might not be safe for young boys who have not yet reached puberty. These products might have hormone effects that could disrupt the normal hormones in a boy's body. In some cases, this has resulted in boys developing abnormal breast growth called gynecomastia. The safety of these products when used by young girls is not known.
