Matters needing attention
Some safety measures are needed in the use of essential oil. Do not use thick undiluted essential oil on your skin. Use essential oil for the first time, or try a new essential oil, you need to use it carefully. Do a skin test first to check for allergic reactions.
Don't use too high a dose often. To achieve the curative effect, it needs a low dose and lasts for a period of time, so the effect of conditioning the body function is appropriate. Usually used, the concentration should be 3-5%, and the more dangerous essential oil should not exceed 3%.
Don't use photosensitive essential oil in places where it will be exposed to the sun. Some essential oils contain components that can cause photosensitivity. If exposed to the sun after use, the skin will turn black and even cause skin cancer. Photosensitivity is also light and heavy, such as grapefruit. It doesn't matter if you use it in small doses at night and bask in the sun the next day. Citrus essential oils, such as lemon, bergamot, orange, sweet orange, lime, angelica dahurica root, lemon verbena and coriander, are all photosensitive essential oils.
Oral instructions must be provided by experts or manufacturers. Not all essential oils can be taken orally. When you can't judge the quality of essential oils, you should be careful when taking them orally.
When the skin has a wound, you should avoid using essential oil, but if it is a small knife wound or a small wound, you can use essential oil to make the skin heal quickly.
Do a skin test before use. Adjust the concentration of 3% essential oil and use it under the armpit or chest. Only when there is no allergy for at least 24 hours can you use essential oil.
Except lavender and tea tree essential oils can be applied on a small area with cotton swabs, unilateral essential oils must be diluted or mixed with base oil before they can directly act on the skin. Composite oil and base oil can be used directly.
Breast-feeding women should avoid breastfeeding for 6 hours by massage, bathing, etc., because essential oil will participate in human blood circulation, and after 6 hours, essential oil will be almost completely metabolized.
It is generally not recommended for women to use essential oils during menstruation, because more than 85% of essential oils have menstrual function, and there may be an increase in menstrual flow and occasional bloody collapse.
During pregnancy, you can use incense all the time It is forbidden to use essential oils for bathing or massage in the first three months of pregnancy, or avoid using essential oils with estrogenic effects during pregnancy because of their menstrual function, such as basil, sage and fennel.

Selection skill
1. Select by appearance label: the appearance label of essential oil is required internationally. The product label usually needs to include: the generic name of the plant variety (which can be used in the production and sales countries), the scientific name of the plant variety (which must be in Latin), the extraction site, extraction method, origin, purity, capacity, etc. Generally, dark glass bottles are used for packaging.
2. Choose from familiar tastes: some varieties that we can come into contact with every day can help us judge the overall quality of the brand from one aspect. Even the same variety of essential oil will have different smells because of the different origin, extraction method, season and year, but it will still retain the unique aroma of this variety of essential oil.
3. Selection of alcohol test method: Most essential oils will be completely dissolved in alcohol. If mixed with vegetable oil or mineral oil, there will be stratification-that is, vegetable oil or mineral oil floats on the surface of alcohol, while essential oils are partially dissolved in alcohol. But it has no test effect on essential oils containing volatile substances.
4. Selection through skin reaction: The purer the essential oil, the stronger the penetration. When buying essential oil, you can gently rub the diluted essential oil on the back of your hand or the inside of your wrist for skin test, and then massage with your fingertips. Good quality essential oil will be absorbed in an instant and will not leave bright oil components on the skin.
5. Selection of essential oil chromatography: Essential oil chromatography is a scientific method to analyze the molecular structure of essential oil. SGS institutions check the quality of essential oil through the chromatogram of essential oil. The application of essential oil chromatogram is mainly reflected in identifying the quality of essential oil. The result of chromatographic analysis is just like the DNA data of essential oil-through these data, the content of each component of essential oil can be clearly obtained, and the quality of essential oil can be scientifically and effectively judged.
