Health benefits of Tea Tree

Plant Description

Tea Tree is an evergreen shrub or small narrow-leaved, hardwood tree that grows about 7 m (20 ft.) tall with a bushy crown. The plant is found growing in swamps by the coast, along streams, on swampy flats, in dense, impenetrable and thickets. The plant thrives best in- a fertile, well-drained moisture retentive lime-free soil in full sun. Prefers seasonally wet areas, standing water or well-drained uplands, can tolerate freezes once established. It does not grow well on shallow light sandy soils, heavy clay soils and acid sulfate soils. The plant has whitish, spongy, peeling, papery bark. The entire plant is glabrous.

Leaves

Leaves are arranged alternately, sometimes scattered or whorled. The leaves are smooth, soft, linear in shape, 10–35 mm (0.4–1 in) long and 1 mm (0.04 in) wide. The petiole is 1 mm long. They are also rich in oil with the glands prominent. Leaves smell of camphor when crushed.

Flowers

The inflorescences are many-flowered spikes, 3-5 cm long over a short period, mostly spring to early summer, with axes bearing short hairs. The white flowers are solitary and petals are 2-3 mm long. The flowers are scattered in an interrupted spike. The stamens are 30-60 in number and more than 12 mm long, united at their bases to form 5 distinct bundles. Flowering normally takes place during June.

Fruits

Fertile flowers are followed by the capsule that continues within the fruiting hypanthium. The fruits are spaced sparsely along the branches. The fruit is small, cylindric or squarish, woody capsules 2–3 mm (0.08–0.1 in) in diameter with many tiny seeds are scattered along the branches. A hole of 1.5-2.5 mm diameter is present which enables the release and dispersal of seeds by wind.

Tea tree, and in particular its essential oil, is one of the most important natural antiseptics. It is useful for stings, burns, wounds, and skin infections of all kinds; the herb merits a place in every medicine chest.

History

Maleleuca alternifolia is native to the eastern half of Australia, known as New South Wales and Queensland. Captain James Cook documented its first use in the 18th century, where he used the leaves to brew an accented tea. Thus, the name “Tea Tree” was created, but the Aboriginal people of Australia had alternative uses for the plant. Native inhabitants used the elasticity and softness of the bark to create sleeping mats and cradles. Additionally, they would use the bark to seal canoe holes, preserve food, and block rainfall. Perhaps the most critical use, which is still appropriate in today’s society, is the use of its oil. The Aboriginal people used the oil on the leaves to cure various skin and health disorders. 

Health benefit of Tea tree

Listed below are some of the popular health benefits of Tea tree

1. Heals Infections

Tea tree essential oil was first investigated in 1923 in Australia. Since the 1960s it has been intensively investigated, and its antiseptic properties are well established. Clinical trials, mainly in Australia, have shown that it is effective at treating a broad range of infectious conditions, particularly fungal and skin problems such as vaginal yeast infections, acne, and warts. It may also be taken internally to treat infections, particularly cystitis, mononucleosis, and post viral fatigue syndrome. It is an excellent remedy for a range of vaginal yeast infections.

2. Skin problems

Active ingredients like terpene hydrocarbons, monoterpenes and sesquiterpenes are found abundantly in tea tree and these compounds give Tea Tree its antibacterial, antiviral and antifungal activity. Tea tree oil or cream can be applied to skin infections such as athlete’s foot and ringworm, as well as to corns, warts, acne and boils, infected burns, scrapes, wounds, insect bites and stings, and other skin conditions.(+)

3. Oral Health

The herb is effective in mouthwashes, countering oral infection and gum disease, and it can also be used as a gargle for sore throats. (+)

4. Wound Healing

Due to its anti-bacterial, anti-microbial and antiseptic compounds, Tea Tree essential oil is an effective wound healer that prevents infection. (+)

Research has concluded that 8 out of 11 wounds treated with Tea Tree reduced in size and began to heal. Another research found that the essential oil was effective at treating antibiotic resistant bacteria, in particular, Staphylococcus aureus.(+)

5. Cure Acne

The anti-microbial and anti-inflammatory properties of Tea Tree make it a widespread essential oil for the treatment of acne, calming redness, swelling and inflammation. Tea Tree may also reduce the appearance of acne scars.

In a research conducted in 2017, the participants applied Tea Tree oil to their faces daily for 12 weeks. At the end of the study the researchers concluded that the use of the Tea Tree oil products considerably improved mild to moderate acne. In another research it was determined to be just as effective at treating acne as benzoyl peroxide, with less chance of severe negative side effects.

6. Skin Infections

Tea tree oil is quite effective for treating fungal infections such as athlete’s foot, candida and toenail fungus. The antimicrobial and antiseptic properties of the oil help to disinfect the affected foot area and prevent spreading of the fungus to other body parts. It also acts as an astringent that decreases the redness, scaly, cracked skin or skin peeling on the infected area, therefore speeding up the healing process.

7. Cold Sores (Herpes)

Tea Tree is quite effective against the herpes simplex virus which causes cold sores. Research concluded that, Tea Tree oil and Eucalyptus oil are capable to exert a direct antiviral effect on HSV (herpes simplex virus). Though the active anti-herpes components of Australian tea tree and eucalyptus oil are not yet known, their possible application as antiviral agents in recurrent herpes infection is promising.” (+)

8. Head Lice

Tea Tree is a potent insecticidal that has proven an effective natural treatment for head lice. Parasitology Research has discovered that a treatment of Tea Tree oil resulted in 100 percent mortality after just 30 minutes of exposure. Additionally, a higher concentration of the essential oil induced a failure of 50 percent of the eggs to hatch. (+)

To make your own natural head lice treatment just add a few drops of Tea Tree oil to your favorite carrier oil, wrap in a towel, leave overnight and wash in the morning. Do this for a few consecutive nights to guarantee the lice and eggs are thoroughly eliminated. (+)

9. Dandruff

Study found that a 5 percent solution of Tea Tree oil was more effective than a placebo at treating dandruff. There was also a reported 41 percent improvement in symptoms. Participants also reported an improvement of itchiness and greasiness after using the Tea Tree shampoo.
