1, air purification and sterilization: Because essential oil has antibacterial and antiseptic components, it has antibacterial, bacteriostatic and antiviral properties.

2. Provide cellular nutrition: Because essential oil contains hormones, vitamins and antibiotics, it can provide cellular nutrition for our body.

3. Balance body and mind: The most important characteristic of essential oil is the sense of smell, which will affect the limbic system of the brain and act on the sense of smell. Tiny aromatic molecules will cause different degrees of psychological and physiological reactions in the central nervous system.

4. Immune function: One of the most important features is that aromatic essential oil helps to strengthen the human immune system and help resist the attacks of various germs and viruses.

Essential oil value

The value of essential oil is not only that there are many synthetic substances, but if these compounds are chemically synthesized and then recombined, the effect of the original essential oil cannot be obtained.

For example, the bactericidal effect of tea tree essential oil is very good, but the effect of using terpinene -4- alcohol (40%) and γ-terpinene (28%) alone is greatly reduced. Lavender essential oil has a good effect on burns and scalds, but the original effect cannot be achieved by analyzing the main components of lavender and recombining it by chemical synthesis.

It can be understood that essential oil is difficult to be replaced by other substances. Another reason why essential oil is called "liquid gold" is its rarity. Because of its complicated manufacturing process and difficulty in obtaining raw materials, it is impossible to produce in large quantities. When plants are planted, if pesticides are sprayed, the effect of the extracted essential oil is also problematic.

Plants also have areas suitable for planting. The same plant, in different regions and different climates, will have different effects on essential oil, and there are differences between polluted and unpolluted plants.

In addition, the extraction of essential oil requires a large number of plants. Only 1 kg of essential oil can be extracted from 200 kg of lavender, 1 kg of essential oil from 2 to 4 metric tons of roses and 1 kg of essential oil from 3,000 lemons. Crop failure or storage problems will affect the cost of essential oil.

Not only can it not be chemically synthesized, but the essential oil must be extracted at the most active time. When plants wither, they lose their value (essential oils are like plant hormones). The storage period and method of the extracted essential oil are also related to whether the essential oil deteriorates or loses its activity. Generally speaking, pure essential oils is preserved for two years. After two years, even if the fragrance remains unchanged, its activity may have been lost.

When the extracted essential oil is stored, it must be stored in a brown or dark bottle to avoid direct sunlight, and stored in a cool place to avoid high temperature deterioration. The prepared essential oil is matched with base oil and stored in the same way, but it is best to use it on the same day and keep it for no more than one month.

However, when the essential oil is mixed with isopropanol, there is no need to consider the storage period. This storage method is relatively safe and simple, but the essential oil with alcohol can only be used in specific perfume bottles. Neither massage nor traditional fumigation can be used.

Harm of improper use of natural essential oil

Lavender and tea tree essential oils are composed of hundreds of chemicals. Researchers at the National Institute of Environmental Health Sciences in the United States examined eight key components and allowed them to act on human cancer cells in the laboratory to observe possible changes.

They found that all eight chemicals activated estrogen to varying degrees and inhibited testosterone at the same time. Of these eight chemicals, four are in lavender and tea tree essential oils, the other four are in two kinds of essential oils respectively, and some chemicals are in at least 65 other essential oils.

Essential oils extracted from plants are widely found in daily chemical products such as shampoo, lotion and soap. Essential oil is also a popular cleaning and medical product. The human body's reaction to essential oils varies from person to person.

Ramsey, the head of the study, believes that the results show that people should use essential oils carefully. "Our society thinks essential oil is safe," he said. "However, it contains many chemical components and should be used with caution, because some components are potential endocrine disruptors." The researchers will present the findings at the annual meeting of the American Endocrine Association.
