A spruce is a tree of the genus Picea , a genus of about 35 species of coniferous evergreen trees in the family Pinaceae, found in the northern temperate and boreal (taiga) regions of the Earth. Picea is the sole genus in the subfamily Piceoideae. Spruces are large trees, from about 20–60 m (about 60–200 ft) tall when mature, and have whorled branches and conical form. They can be distinguished from other members of the pine family by their needles (leaves), which are four-sided and attached singly ...

Tea tree is a very well-known essential oil, which is usually used because of its strong antifungal properties. Tea Tree (or Melaleuca Alternifolia) is also one of the most widely studied, documented and clinically proven therapeutic essential oils available for use today. Tea tree is one of the oils that have been used in folk medicine for millennia and is one of the strongest antiseptics. The oil is obtained from leaves and branches by steam distillation and is used as complementary therapy in surgery, with various types of burns and dental problems, bronchial congestion, infected wounds and much more.

Origin and essence of the tea tree (Melaleuca Alternifolia)

Origin-and-essence-of-the-tea-tree-(Melaleuca-Alternifolia)_0_0

Melaleuca alternifolia, commonly known as "tea tree", is a type of tree or tall shrub of the Myrtovi family - Myrtaceae. Endemic species for Australia (characteristic ofa certain geographical location), Melaleuca Alternifolia is found in southeastern Queensland and the north coast and adjacent ridges of New South Wales, where it grows along streams and in swampy plains and is often the dominant species, where it can be detected. [ref.1]

Melaleuca alternifolia has been used as a tool of traditional medicine by Aborigines. These Indigenous Australians crush the tea tree leaves to extract the oil, which is then inhaled to treat cough and cold or applied directly to the skin.

In fact, the plant did not get the name "tea tree" until 1770, when the name was given by British explorer Captain James Cook and his crew. Although Cook's crew first used the tea leaves, he later mixed them with spruce leaves like beer. The medicinal properties of the plant remained a secret to Australian Aborigines until the early 1920s, when the chemist from Sydney, Australia, Dr Arthur Penfold, examined its antiseptic properties. A short time later, Penfold published "Australian Tea Trees of Economic Value."

Today, tea tree oil is widely available as 100% undiluted or "clean" oil. Diluted forms are also available, ranging from 5-50% in products intended for the skin. It is more interesting to tell you about what oil can be useful for and how it is used, so we continue with the answers to these questions.

Composition-and-useful-properties-of-the-tea-tree

Composition and useful properties of the tea tree

Composition

Composition_1_0

Tea tree oil consists of terpene hydrocarbons, mainly monoterpenes, sesquiterpenes and related alcohols. Terpenes are volatile, aromatic hydrocarbons and can be considered polymers of isoprene, which has a formula C5H8. The more significant are terpinen-4-ol, γ-terpinene, 1,8-eneol, α-terpinene, α-terpineol, p-cimen and α-pinene. With biological activity, the antimicrobial activity of tea tree oil is mainly attributed to terpine-4-ol.

It is known that a wide variety of essential oils have antimicrobial properties, and in many cases this activity is due to the presence of active monoterpene ingredients. This also applies to the tea tree - Melaleuca Alternifolia has proven antimicrobial and anti-inflammatory effect thanks to its components, as well as proven clinical efficacy [ref.1]

Antimicrobial-action_1_1

The in vitro antifungal activity of Melaleuca alternifolia essential oil was evaluated against 26 strains of different types of dermatophytes, 54 yeasts, including 32 strains of Candida albicans and other Candida sp., as well as 22 different strains of Malassezia furfur. [ref.2] Tea tree oil inhibits breathing in cell suspensions of E. coli, providing evidence of lethal action associated with damage to the cytoplasmic membrane. [ref.8]

Antimicrobial-action_1_2

Similar to the results found for bacteria, tea tree oil alters the permeability of C. albicans cells, as well as the opportunistic Candida glabrata, which has high resistance to certain antifungal drugs and can cause infections affecting the urinary tract, genitals, mouth or blood flow (in some risk groups with impaired immunity, this is especially dangerous). [ref. 3, 4]

Antimicrobial-action_1_3

From the more recent discoveries about the tea tree, the most promising new function of the oil is counteracting the methicillin-resistant Staphylococcus aureus (MRSA). [ref.5]

Anti-inflammatory-action

Anti-inflammatory action

Anti-inflammatory-action_1_0

Tea tree oil can help reduce inflammation, which is due to the high concentration of terpine-4-ol, a compound with anti-inflammatory properties. In animal tests, terpine-4-ol was found to suppress inflammatory activity in cases of infection in the mouth. In humans, locally applied tea tree oil reduces edema more effectively in inflammation of the skin caused by histamine than paraffin oil.

Anti-inflammatory-action_1_1

In vitro studies over the past decade have shown that tea tree oil affects a number of immune responses, both in vitro and in vivo. For example, water-soluble components of oil can inhibit lipopolysaccharides-induced production of inflammatory mediators tumor necrosis factor alpha (TNF-α), interleukin-1β (IL-1β) and IL-10 from monocytes of human peripheral blood by approximately 50% and that of prostaglandin E2 by about 30%.

Anti-inflammatory-action_1_2

Another interesting field of research shows that terpine-4-ol modulates vasodilation and plasma extravasation associated with histamine-induced inflammation in humans. In other words, the active ingredient of the oil can help alleviate the symptoms of histamine intolerance.

Anti-inflammatory-action_1_3

The potential anti-inflammatory effects of Melaleuca alternifolia essential oil on human peripheral blood leukocytes also examined the fungicidal and bactericidal action of Melaleuca alternifolia essential oil. Data show that Melaleuca alternifolia can effectively protect the body by reducing the proliferation of inflammatory cells without affecting their ability to secrete anti-inflammatory cytokines. [ref.9].
