Can you eat tea tree oil?

Yes, you can eat tea tree oil. For acne and other superficial skin problems, tea tree oil is typically harmless when used topically. Tea tree oil is harmful if ingested, therefore avoid using it orally.

Steaming Australian tea tree leaves yields an essential oil known as melaleuca oil, often known as tea tree oil. Tea tree oil, when used topically, is thought to be antibacterial. Acne, athlete’s foot, lice, nail fungus, and insect bites may all be treated with tea tree oil.

There are various over-the-counter skincare products that include tea tree oil, such as soaps and lotions. Tea tree oil, on the other hand, should not be ingested. If ingested, it may result in major health complications.

Typical applications: 

Tea tree oil has been used for a variety of purposes, both conventional and speculative, according to the NLM. All of these applications haven’t been studied for safety or efficacy, according to NLM. Tea tree oil has traditionally been used to treat a wide range of skin ailments, including burns, cuts, canker sores, corns, eczema, insect bites, rosacea, scabies, and more. 

Colds, coughs, bronchial congestion, and irritation of the nose and throat are among the respiratory ailments that have been reported. Melanoma, body odor, and infections of the bone and prostate are all cited as traditional applications.

Study after study shows that tea tree oil has some anti-fungal and anti-microbial properties when it comes to individual cells. Tea tree oil has been shown to be beneficial and safe in a small number of human investigations, however, these results have not been replicated. Tea tree oil’s ability to strengthen the immune system has yet to be shown by scientific research.

Here are a few studies looking at how they affect skin conditions:

  • Tea tree oil and clotrimazole were evaluated in 1994 research for the treatment of fingernail fungus. They both had a similar impact.
  • It was discovered in 1990 research that tea tree oil and benzoyl peroxide both worked, although tea tree oil took longer to take effect and had fewer negative effects.
  • Tolnaftate was shown to be more effective than tea tree oil in healing the fungus infection in 1992 research, however tea tree oil improved the patient’s symptoms as much as tolnaftate.

Side Effects

Tea tree oil’s side effects include skin irritation, particularly at higher quantities. It has also been linked to skin problems, including hives. So far, there has been one case of breast augmentation among boys under the age of 18 who used lavender and tea tree oils in their personal care products. 

If this were a frequent effect, it would have been noticed long ago; the authors published the information so that doctors may use essential oils in the treatment of boys with breast growth.).


Tea tree oil is considered to be toxic if ingested, therefore it’s best not to use it unless absolutely necessary. Mistakenly delivered to him by his mother, the infant ended up in the hospital (from which he recovered). 

For whatever reason, tea tree oil should not be swallowed. Traditional applications of tea tree oil include mouthwash, foul breath therapy, and toothache and oral ulcer treatment.

Tea tree oil and pets

Anecdotal evidence suggests that high doses of tea tree oil applied to the skin of cats and dogs may cause toxicity and death. Muscle tremors, weakness, trouble walking, low body temperature, and excessive salivation have all been reported as possible side effects. It’s just as important to obey label directions for dogs as it is for human beings.

Non-medicinal uses

Tea tree oil may be found in a variety of home items, including cleaning products, as well as in toothpaste. As a “natural” and “green” product, it is marketed as such. Although “natural” does not always equal “non-toxic,” tea tree oil is unpleasant to certain individuals and is dangerous if ingested in large amounts. 

Studies are also required to assess whether or not tea tree oil is safe for the environment. In order to keep these goods out of the hands of youngsters, they should be kept in their original containers, away from medications or food.
