Tea tree oil can be referred to by various names depending on locality and dialect. The names are mainly based on the Melaleuca alternifolia from which the oil is extracted. Some of the most common alternative names include;
Melaleuca alternifolia is a tree that grows in Australia's coastal areas of New South Wales and Queensland. It is from this tree that tea tree oil is derived. Steam distillation separates the oil from the leaves of this plant by capturing natural plant compounds. The oil is typically pale yellow with a camphor-like scent.
Essential oil has many health benefits due to its broad-spectrum action, which comprises both antimicrobial and anti-inflammatory properties. Whether for skin conditions, infections, or inflammatory diseases, it often falls as a natural remedy for tea tree oil. Here are some of the prominent health benefits of this essential oil:
Tea tree oil is one of the most used natural remedies for acne. As an antibacterial, it fights the bacteria causing acne and dries out the pores that cause the condition. This means it limits breakouts due to inflammation. It has the added advantage of drying whiteheads, blackheads, and other blemishes without causing irritation and dryness like synthetic treatments for acne are notorious for. Research has revealed that tea tree oil can be at par with benzoyl peroxide in treating acne.
It can be a common but brutal infection, and the oil's antifungal properties make it an effective treatment. Tea tree oil applied to the infected nail helps fight the growth of fungi, reduces discoloration of the nail, and improves its general appearance. In some cases, consistent application for several weeks is necessary before seeing healthy nail restoration with no side effects commonly associated with chemical treatments is possible. Regular use may prevent reoccurrence.
Dandruff, often caused by an oily scalp and yeast overgrowth, can be effectively managed using tea tree oil. The oil has antifungal properties that combat yeast on the scalp, reducing flakiness, itching, and irritation. Regular tea tree oil-infused shampoo can help balance scalp oils and maintain a healthy scalp environment, preventing dandruff from recurring.
Athlete's foot, or tinea pedis, is a fungus infection causing peeling, itchiness, and discomfort in the interspace between the fourth and fifth toes. Due to its extreme antifungal properties, one can use tea tree oil to alleviate the effects and prevent the spread of the disease. Applying the oil diluted to a suitable concentration to the infected areas will accelerate recovery and diminish itching and swelling.
Another application of tea tree oil is against various fungal infections, including ringworm and jock itch, apart from athlete's foot and nail infections. Most infections are caused by dermatophytes, fungi that thrive in warm, moist environments. Tea tree oil kills the fungi and prevents their spread to other body parts.
Although not consumed, the oil can be taken in gargle form (diluted) to help heal a sore throat caused by bacteria or fungi because of its anti-inflammatory and antimicrobial properties. It helps reduce inflammation in the throat and attack the infection. However, it should never be ingested since it will poison the system if swallowed.
There are other applications of tea tree oil, too, which are an herbal remedy for yeast infections within the vagina. While it targets antifungal activity, it reduces burning itchiness and discharge, for example. Most women would use tea tree oil suppositories; however, they should only do this under the guidance of a healthcare provider to avoid irritation or worsening of the condition.
Even though there is much praise for tea tree oil, one has to use it properly. The following are some precautions you should note.
