Explore the diverse genus of Eucalyptus plants, which includes over 700 species native to Australia and other regions. Learn about their evergreen nature, leaf shedding, and unique crown shape, as well as their medicinal and economic significance. Find out more here!
Eucalyptus is the collective name for plants of the genus Eucalyptus in the Myrtle family, which probably originated in the late Cretaceous period. Of the more than 700 known species of eucalyptus, most are native to the Australian mainland, with a smaller number growing in the neighboring islands of New Guinea, Indonesia, and the Philippines. It was introduced to the world in the 19th century, and by 2012, it was cultivated in 96 countries or regions. Evergreen plants, a year with periodic old leaf shedding phenomenon, most varieties are tall trees, a few are small trees, shrubby few. The crown shape has spire shape, multi branches and hanging branches and so on. Leaves simple, entire, leathery, sometimes covered with a thin waxy coating. Leaves can be divided into juvenile, intermediate, and mature leaves, with most species having opposite, smaller, heart-shaped, or broadly lanceolate leaves.
They are of medicinal and economic value.

Main value

Economy

China has successfully developed the manufacturing technology of high performance eucalyptus recombination wood, eucalyptus veneer laminated wood, bamboo eucalyptus composite material, thick core eucalyptus solid wood composite board and aldehyde-free eucalyptus plywood, etc. The comprehensive utilization rate of eucalyptus can be increased to more than 90%. Eucalyptus not only brings value to industry, but also brings economic benefits to other industries.

Paper and pulp

Eucalyptus papermaking has been going on since the early 20th century. The average length of eucalyptus fibers is 0.75 to 1.30 mm. Its color, density and extract ratio are suitable for pulping. There are also many large paper mills that use eucalyptus to make kraft paper and printer paper. The cellulose in eucalyptus wood can be made into dissolved wood pulp and then processed into rayon with considerable success.

Oil refining

Eucalyptus varieties are blue, straight rod, Smith, large leaf, small leaf, red leaf, etc. Among them, blue eucalyptus and straight eucalyptus are the main varieties used to extract eucalyptus oil. Eucalyptus oil contains ebulliol, which is colorless or light yellow liquid. It has pungent and cool fragrance. It is mainly used in toothpaste,mouthwash, food and medicine, etc. Eucalyptus globulus and Eucalyptus verticale have excellent species, and the best quality is to extract eucalyptus oil from its branches and leaves.

 

Gold content

Australian scientists have used X-rays to find trace amounts of gold in the leaves of eucalyptus trees, in what is believed to be the first time humans have found naturally occurring gold in a living organism.The scientists found that eucalyptus and acacia trees in western and southern Australia have deep and extensive root systems. During periods of drought, their roots dig deep into the ground in search of water, some reaching gold veins and sucking up tiny bits of gold. The roots then dilute the gold and transmit it to the tree's venation system, where large amounts of gold accumulate at the tips of the leaves and can form larger crystals.

The scientists further point out that gold is toxic to plants, so it is transported to the ends of plants, such as leaves, where damaging biochemical reactions are reduced.

What's more, the amount of gold in the leaves is so small that the leaves of 500 eucalyptus trees growing in the gold mining region might contain enough gold to make a wedding ring, so the discovery won't be a fortune for gold seekers, the researchers said. However, the scientists noted that the discovery could help explore for gold in a more environmentally friendly and inexpensive way.

Eat

The roots of eucalyptus trees can be eaten or taken for water. There are also places that use eucalyptus for fuel. There are many eucalyptus leaves that can be used as fodder.

Medicine

Eucalyptus oil can be produced by water distillation with fresh leaves of eucalyptus (oil yield 0.5-1.8%). Eucalyptus mainly contains eucalyptus oil (65-75%). Terpene, isoamyl oil, carvidone, humenthone, piperone and other components. It can also be used as medicinal raw materials for oral cavity, rhinitis, expectorant, cooling oil, wind drive ointment and so on.
