The efficacy and function of eucalyptus leaves were directly applied.

Eucalyptus leaves are a special food for koalas, which are often used to extract insect repellents and deodorants. Do eucalyptus leaves have any other uses or negative aspects?

I. the efficacy and function of eucalyptus leaves

Efficacy:

1. Body:

The greatest effect of eucalyptus essential oil in application is that it is effective against all kinds of inflammation and fever. For patients with high fever, eucalyptus essential oil can quickly lower body temperature.

Eucalyptus essential oil is one of the best fungicides, which not only has strong bactericidal power, but also can reduce the viscosity of mucus in the body, so it can be used in physiotherapy for pulmonary tuberculosis, bronchitis, diphtheria, etc., which can ease inflammation and make mucous membrane comfortable.

Eucalyptus essential oil has the effects of anti-spasm, relieving pain, relieving muscle soreness and rheumatism. It is often added to basic massage oil to relieve muscle stiffness and pain.

Eucalyptus leaves have disinfection effect.

Through experiments, Hiroshi Hamada, a professor at Okayama University in Japan, and Fuliang, a researcher, have found that the cultured cells of eucalyptus leaves can effectively eliminate the toxicity of harmful chemical bisphenol A.

Bisphenol A, a compound commonly used in the manufacture of plastics and paints, has recently been found to have the potential to reduce the number of sperm in animals, so it has been added to the list of "environmental hormones"-chemicals that disrupt the endocrine system in Japan.

Professor Hamada recently told the media that they put the cultured cells of eucalyptus leaves processed into particles into a solution of bisphenol A with a concentration of 1PPM (1/1000000). Three days later, they found that the toxicity of bisphenol A disappeared and became a harmless substance.

In addition, according to Akita Akita, manager of the ecological technology company that conducted cooperative research with the two scientists, this function of eucalyptus leaves can be further enhanced through transgenic technology. At present, the company is working to further develop and improve this technology, and finally reach the practical stage to produce environmental protection products that can be applied in practice.

2. Psychology:

The cool and pleasant smell of eucalyptus essential oil extracted from eucalyptus leaves makes people feel refreshed, clear-headed and focused. Students use less. 3. Hair and skin care:

Eucalyptus essential oil can eliminate pore blockage, eliminate acne, promote blood circulation and explain tissue regeneration.

4. Points for attention:

Avoid use in patients with hypertension, epilepsy and broad bean disease.

Eucalyptus leaves

Eucalyptus leaves are a special food for koalas, which are often used to extract insect repellents and deodorants.

Eucalyptus leaf blight

1. Distribution and harm

Eucalyptus leaf blight is distributed all over South China. Harm to Eucalyptus urophylla, Eucalyptus grandis, Eucalyptus urophylla and Eucalyptus urophylla 2. Symptoms of the disease often occur at leaf tip and leaf margin. At the initial stage of the disease, chlorotic spots appeared on the susceptible leaves, and then gradually expanded into irregular spots, brown or gray, resulting in the death of leaves more than 1 big 3 or 1 big 2. In the later stage of the disease, black dots are produced on the disease spot, which is the conidium of the pathogen. The disease spots on Eucalyptus urophylla often show wheel patterns.

3. Pathogen

The pathogen is Coniothyriumsp., which belongs to the subphylum Cellulospora, Cellulospora and Cephalospora 4. The regular pathogen lurks in the host tissue and produces conidia to infect the host when the conditions are right. The disease is serious in young trees, the weather is dry, the soil is poor, the plant growth is poor, and the disease is serious.

5. Prevention and control methods

Strengthen tending management, timely drought resistance, proper topdressing, so as to make the plant grow well and improve the disease resistance of seedlings.

Chemical prevention and treatment: Guoguang Yintai (80% Dysen zinc wettable powder) 600-800 times solution + Guoguang Sitalin (foliar fertilizer with amino acid chelating a variety of trace elements) can be sprayed regularly to prevent and supplement nutrition before disease prevention and improve ornamental; at the initial stage of the disease, spray 25% prochloraz EC (such as Guoguang must fresh) 500-600 times, or more than 50% manganese zinc wettable powder (such as Guoguang Yingna) 400-600 times. Use it 2-3 times at intervals of 7-10 days.

Are eucalyptus leaves poisonous

One theory is that eucalyptus is not only non-toxic, but also can be directly used by animals and humans. There is an animal called koala (koala) in Australia. It lives in eucalyptus forest and eats eucalyptus leaves for a living. If eucalyptus is poisonous, can animals eat it? In addition, Australia is full of eucalyptus forests from south to north, and the drinking water conservation forests in major cities are basically eucalyptus trees, but life-oriented Australians have never reflected that the water sources in eucalyptus forest areas are not good, let alone toxic. In addition, eucalyptus has a by-product-eucalyptus oil, a class of natural compounds extracted from eucalyptus leaves, is used in cosmetics and medicine raw materials, many throat tablets contain eucalyptus oil. Therefore, it is completely nonsense to say that eucalyptus is poisonous, mainly because people do not know about eucalyptus.

Another theory is that the koala is a very picky animal that feeds only on Australian eucalyptus leaves. Eucalyptus leaves are particularly high in fiber, but low in nutrition, and for other animals, eucalyptus leaves are highly toxic.

In order to adapt to this low-nutritional food, koalas have long evolved a special organ for digesting fiber-the cecum. Other animals, such as humans, also have a cecum, but it is nothing compared to the koala's 2-meter-long cecum. Millions of microbes in the cecum can break down the fiber in food into nutrients that koalas can absorb.

Eucalyptus leaves have both advantages and disadvantages, we have to choose the right eucalyptus leaves in order to maximize the role of eucalyptus leaves.
