There is insufficient evidence to support the use of tea tree oil in humans as a treatment for methicillin-resistant Staphylococcus aureus, or MRSA. Some laboratory research implies potential antibacterial activity but not enough to warrant its use. Tea tree oil has been used as a topical antiseptic for burns, insect bites, cuts, abrasions and boils. Until concrete evidence proves its effectiveness against Staphylococcus aureus beyond the laboratory, tea tree oil remains controversial in its value against it.
Tea Tree History
Originally named by Captain Cook in the eighteenth century, the tea tree leaves were used to make a tea that had the aroma of nutmeg. Over a century later, A.R. Penfold, an Australian chemist, determined that tea tree leaves had antiseptic characteristics and thus used the resin to treat wounds. During WWII, the government of Australia determined that tea tree oil was a vital product for treating wounds, and for this reason, manufacturers producing it were excused from service in the military.
Staphylococcus aureus
Staphylococcus aureus bacteria is commonly found in the nose and on the skin of otherwise healthy people. MRSA is a category of Staphylococcus aureus that has resistance to antibiotics, such as methicillin, penicillin and amoxicillin, as a result of excessive use of antibiotics and the ability of the bacteria to raise its defense system against antibiotics. MRSA is frequently associated with recurrent and acute skin and soft tissue infections, which can become life-threatening despite treatment.
Tea Tree Oil Uses
Tea tree oil has been used topically to treat superficial bacterial infections, fungal infections and parasites such as acne, lice, scabies and ringworm. Other uses include vaginal infections, cold sores, toothache, sore throat and ear infections but more proof is required to validate its effectiveness as a treatment. Tea tree oil is not classified as a medication and has not been subjected to rigorous screening by the U.S. Food and Drug Administration. Consult your physician before using tea tree oil.
Side Effects
Tea tree oil can cause severe skin reactions when applied topically and oral consumption can cause confusion, rash, difficulty walking and coma. Mixtures of tea tree oil and lavender oil might alter normal hormone levels in prepubescent boys. The mixture might have estrogen-like and testosterone blocking activity. Its side effects with girls have not been identified.
