A plant genus of the family MYRTACEAE. M. alternifolia foliage is a source of TEA TREE OIL. The common name of tea tree also refers to LEPTOSPERMUM or KUNZEA. M. vindifolia is a source of niaouli oil. M. cajuputi and M. leucadendra are sources of cajuput oil.
Essential oil extracted from Melaleuca alternifolia (tea tree). It is used as a topical antimicrobial due to the presence of terpineol.
A plant genus of the family SIMAROUBACEAE. Members produce quassinoids.
Oils which evaporate readily. The volatile oils occur in aromatic plants, to which they give odor and other characteristics. Most volatile oils consist of a mixture of two or more TERPENES or of a mixture of an eleoptene (the more volatile constituent of a volatile oil) with a stearopten (the more solid constituent). The synonym essential oils refers to the essence of a plant, as its perfume or scent, and not to its indispensability.
Compounds with a core of 10 carbons generally formed via the mevalonate pathway from the combination of 3,3-dimethylallyl pyrophosphate and isopentenyl pyrophosphate. They are cyclized and oxidized in a variety of ways. Due to the low molecular weight many of them exist in the form of essential oils (OILS, VOLATILE).
A class of compounds composed of repeating 5-carbon units of HEMITERPENES.

In vitro activity of Melaleuca alternifolia (tea tree) oil against dermatophytes and other filamentous fungi. (1/16)

The in vitro activity of Melaleuca alternifolia (tea tree) oil against dermatophytes (n = 106) and filamentous fungi (n = 78) was determined. Tea tree oil MICs for all fungi ranged from 0.004% to 0.25% and minimum fungicidal concentrations (MFCs) ranged from <0.03% to 8.0%. Time-kill experiments with 1-4 x MFC demonstrated that three of the four test organisms were still detected after 8 h of treatment, but not after 24 h. Comparison of the susceptibility to tea tree oil of germinated and non-germinated Aspergillus niger conidia showed germinated conidia to be more susceptible than non-germinated conidia. These data demonstrate that tea tree oil has both inhibitory and fungicidal activity.  (+info)

Terpinen-4-ol, the main component of Melaleuca alternifolia (tea tree) oil inhibits the in vitro growth of human melanoma cells. (2/16)

The search for innovative therapeutic approaches based on the use of new substances is gaining more interest in clinical oncology. In this in vitro study the potential anti-tumoral activity of tea tree oil, distilled from Melaleuca alternifolia, was analyzed against human melanoma M14 WT cells and their drug-resistant counterparts, M14 adriamicin-resistant cells. Both sensitive and resistant cells were grown in the presence of tea tree oil at concentrations ranging from 0.005 to 0.03%. Both the complex oil (tea tree oil) and its main active component terpinen-4-ol were able to induce caspase-dependent apoptosis of melanoma cells and this effect was more evident in the resistant variant cell population. Freeze-fracturing and scanning electron microscopy analyses suggested that the effect of the crude oil and of the terpinen-4-ol was mediated by their interaction with plasma membrane and subsequent reorganization of membrane lipids. In conclusion, tea tree oil and terpinen-4-ol are able to impair the growth of human M14 melanoma cells and appear to be more effective on their resistant variants, which express high levels of P-glycoprotein in the plasma membrane, overcoming resistance to caspase-dependent apoptosis exerted by P-glycoprotein-positive tumor cells.  (+info)

Effect of Australian tea tree oil on Gyrodactylus spp. infection of the three-spined stickleback Gasterosteus aculeatus. (3/16)

Gyrodactylus spp. infections of commercially farmed fishes are responsible for significant economic losses. Existing treatments have proved uneconomic, stressful to the fishes, and ecologically damaging. Essential oils are naturally occurring compounds that exhibit a wide range of anti-microbial and anti-fungal activities. This study explored the possibility of using Australian tea tree (Melaleuca alternifolia) oil (TTO) to treat Gyrodactylus spp. infection on the three-spined stickleback Gasterosteus aculeatus. In the presence of 0.01 % Tween 80 as an emulsifier, TTO treatments at concentrations between 3 and 30 ppmv (parts per million by volume) lowered the prevalence and significantly reduced the parasite burden of sticklebacks naturally infected with Gyrodactylus spp. In addition, Tween 80 alone exhibited parasiticidal activity against Gyrodactylus spp. These findings show the potential of TTO in combination with Tween 80 as an effective treatment of Gyrodactylus spp. infection of fishes.  (+info)

Melaleuca alternifolia (Tea Tree) oil: a review of antimicrobial and other medicinal properties. (4/16)

Complementary and alternative medicines such as tea tree (melaleuca) oil have become increasingly popular in recent decades. This essential oil has been used for almost 100 years in Australia but is now available worldwide both as neat oil and as an active component in an array of products. The primary uses of tea tree oil have historically capitalized on the antiseptic and anti-inflammatory actions of the oil. This review summarizes recent developments in our understanding of the antimicrobial and anti-inflammatory activities of the oil and its components, as well as clinical efficacy. Specific mechanisms of antimicrobial and anti-inflammatory action are reviewed, and the toxicity of the oil is briefly discussed.  (+info)

In vivo activity of terpinen-4-ol, the main bioactive component of Melaleuca alternifolia Cheel (tea tree) oil against azole-susceptible and -resistant human pathogenic Candida species. (5/16)

BACKGROUND: Recent investigations on the antifungal properties of essential oil of Melaleuca alternifolia Cheel (Tea Tree Oil, TTO) have been performed with reference to the treatment of vaginal candidiasis. However, there is a lack of in vivo data supporting in vitro results, especially regarding the antifungal properties of TTO constituents. Thus, the aim of our study was to investigate the in vitro and the in vivo anti-Candida activity of two critical bioactive constituents of TTO, terpinen-4-ol and 1,8-cineole. METHODS: Oophorectomized, pseudoestrus rats under estrogen treatment were used for experimental vaginal infection with azole (fluconazole, itraconazole) -susceptible or -resistant strains of C. albicans. All these strains were preliminarily tested for in vitro susceptibility to TTO, terpinen-4-ol and 1,8-cineole for their antifungal properties, using a modification of the CLSI (formerly NCCLS) reference M27-A2 broth micro-dilution method. RESULTS: In vitro minimal inhibitory concentrations (MIC90) values were 0.06% (volume/volume) for terpinen-4-ol and 4% (volume/volume) for 1,8-cineole, regardless of susceptibility or resistance of the strains to fluconazole and itraconazole. Fungicidal concentrations of terpinen-4-ol were equivalent to the candidastatic activity. In the rat vaginal infection model, terpinen-4-ol was as active as TTO in accelerating clearance from the vagina of all Candida strains examined. CONCLUSION: Our data suggest that terpinen-4-ol is a likely mediator of the in vitro and in vivo activity of TTO. This is the first in vivo demonstration that terpinen-4-ol could control C. albicans vaginal infections. The purified compound holds promise for the treatment of vaginal candidiasis, and particularly the azole-resistant forms.  (+info)

"Melaleuca" is a genus of plants, also known as tea trees, that are native to Australia. The term itself is not typically used in medical contexts, but some Melaleuca species do have medicinal properties. For example, the oil from Melaleuca alternifolia, commonly called tea tree oil, has been found to have antimicrobial and anti-inflammatory effects and is sometimes used topically for skin conditions such as acne, fungal infections, and insect bites. However, it's important to note that essential oils should be used with caution and under the guidance of a healthcare provider, as they can cause skin irritation or other adverse reactions in some people.

Tea tree oil, also known as melaleuca oil, is an essential oil derived from the leaves of the tea tree (Melaleuca alternifolia), which is native to Australia. It has been used traditionally by Aboriginal people for centuries for its medicinal properties. Tea tree oil is known for its antimicrobial, anti-inflammatory, and antiseptic qualities. It contains a number of compounds, including terpinen-4-ol, that have been shown to kill bacteria, viruses, fungi, and parasites.

Tea tree oil is often used topically and has been found to be effective in treating various skin conditions such as acne, fungal infections, insect bites, and minor wounds. However, it should not be ingested as it can cause adverse reactions when taken internally. It's important to dilute tea tree oil with a carrier oil before applying it to the skin, as it can cause irritation if used undiluted.

While tea tree oil has many potential benefits, it's essential to use it cautiously and under the guidance of a healthcare professional, as it may interact with certain medications or have adverse effects on people with specific health conditions.

I'm sorry for any confusion, but "Simarouba" is not a medical term that has a specific definition in the field of medicine. It is actually the name of a genus of trees that are native to the Americas. The bark and seeds of some species of Simarouba have been used in traditional medicine systems, such as in South America and India, for various purposes including as a treatment for diarrhea, fever, and skin conditions. However, there is limited scientific evidence to support these uses, and more research is needed before any definitive medical claims can be made about the therapeutic benefits of Simarouba.

Volatile oils, also known as essential oils, are a type of organic compound that are naturally produced in plants. They are called "volatile" because they evaporate quickly at room temperature due to their high vapor pressure. These oils are composed of complex mixtures of various compounds, including terpenes, terpenoids, aldehydes, ketones, esters, and alcohols. They are responsible for the characteristic aroma and flavor of many plants and are often used in perfumes, flavors, and aromatherapy. In a medical context, volatile oils may have therapeutic properties and be used in certain medications or treatments, but it's important to note that they can also cause adverse reactions if not used properly.

Monoterpenes are a class of terpenes that consist of two isoprene units and have the molecular formula C10H16. They are major components of many essential oils found in plants, giving them their characteristic fragrances and flavors. Monoterpenes can be further classified into various subgroups based on their structural features, such as acyclic (e.g., myrcene), monocyclic (e.g., limonene), and bicyclic (e.g., pinene) compounds. In the medical field, monoterpenes have been studied for their potential therapeutic properties, including anti-inflammatory, antimicrobial, and anticancer activities. However, more research is needed to fully understand their mechanisms of action and clinical applications.

Terpenes are a large and diverse class of organic compounds produced by a variety of plants, including cannabis. They are responsible for the distinctive aromas and flavors found in different strains of cannabis. Terpenes have been found to have various therapeutic benefits, such as anti-inflammatory, analgesic, and antimicrobial properties. Some terpenes may also enhance the psychoactive effects of THC, the main psychoactive compound in cannabis. It's important to note that more research is needed to fully understand the potential medical benefits and risks associated with terpenes.
