Backhousia myrtifolia

[7] B. myrtifolia is a canopy species of plant (occupying high light environments) that form coppiced thick trunks, and tend to grow in warmer, temperate rainforest conditions.

[7] These plants tend to bloom between late spring and early summer, producing ivory white starfish-shaped flowers with 5 individual sepals and capsule like fruiting bodies.

[8] Lastly, oil glands are visible as fine white dots throughout the leaf's structure and are responsible for the release of four major organic compounds: methyl eugenol, (E)-methyl isoeugenol, elemicin and (E)-isoelemicin which collectively produce the plant's distinct cinnamon-like aroma.

[1] Maximum growth is achieved in the presence of oxygen-rich air (minimal carbon or nitric oxide pollutants) as well as nutrient-abundant soil, rich in micro-organism and mineral diversity.

[11] In addition to this B.myrtifolia tolerates drought, periods of inundation and repeated root disturbance, meaning that they are capable of flourishing in areas that experience constant temperature, and weather fluctuations.

[5] In these urban settings Backhousia myrtifolia has an average life expectancy of 60 years, requiring very little maintenance, presuming it receives consistently high sunlight levels.

[citation needed] The methyl eugenol and elemicin components of B. myrtifolia's natural oils are very potent anti-septic agents, capable of inhibiting the growth of over 100 species of bacteria cumulatively.

[citation needed] Consequently, the Aqueous and methanolic leaf extracts of B. Myrtifolia were found to inhibit the growth of both Proteus mirabilis and Escherichia coli bacteria.

[20] In addition to this, the oils produced by the B. myrtifolia plants are non-toxic (as determined by an Artemia franciscana nauplii bioassay) further supporting their use as either an internal or topical treatment for bacterial/fungal infections.

[citation needed] In this same vein of thought, the anti-septic properties of Backhousia myrtifolia's oils also make it suitable for use as an insect repellent against common disease-carrying arthropods such as mosquitoes, flies and beetles.

[22] In countries such as Indonesia and Papua New Guinea, where the rates of mosquito spread malaria and West Nile virus are high, B. myrtifolia based repellents would be especially useful.

To match the slowly increasing demand for the plant in various countries including Asia and Western Europe, Australians in southern NSW began to develop farms dedicated to its production.
