Plant essential oil refers to the secondary metabolic product of plant extracted from plant roots, stems, leaves, flowers, skins, whole grass, and fruits. Its molecular weight is small and can be distilled with water vapor, and it has a certain aromatic odor and strong volatile oily substance. Plant essential oils can help the human body in three aspects: pharmacology, physiology and psychology. Essential oils are divided into the following categories according to their usage and effects:

1. Base oil : Base oil refers to a vegetable oil used to dilute single essential oil, also known as medium oil or base oil. The concentration of essential oils is very high. Most plant essential oils cannot be applied directly to the skin (except for lavender and tea tree essential oil). They must be mixed and diluted with the base oil before they can be applied to the human skin on a large scale.
Function: base oil has the effect of buffering, diluting and assisting single-sided essential oils. Mixing base oil with a certain concentration of single-element oil can harmonize single-element oil and reduce its concentration.
2. Universal essential oil: Universal essential oil is an essence extracted from the whole plant or a certain part of a plant. It has high purity and can only be used on the skin after being fully diluted. Generally speaking, single-sided essential oil can be extracted in a very small amount by using a large amount of plant materials, so the cost is extremely high.
Function: single-sided essential oil is usually named after the plant, with specific effects and personality characteristics.
3. Compound essential oil: compound essential oil refers to essential oils that mix more than 2 types of single essential oils in proportion. Generally, it cannot directly act on the skin. After mixing it with base oil in proportion to form compound essence oil, it can directly act on the skin.
Function: essential oils and essential oils are coordinated and complementary to each other. Compound essential oils have the effect of enhancing the efficacy and expanding the scope of use.
4. Solid Dew: Solid Dew refers to the water left behind by essential oil during distillation and extraction, and is a sub-material of essential oil. Can be applied directly to the skin without dilution.
Function: floral puree has very good skin care value. It can be used with essential oils or can replace essential oils to become an additive in cosmetics or skin care products.
essential oil enters the body through the skin and smell. There are three ways:
1. Sniff through the nose
essential oil is a highly volatile substance that can gradually spread throughout the room at room temperature. If it is heated, it will fill the air faster. Plant molecules will be inhaled into the body during breathing. This method is most effective in headache, insomnia, emotional instability and respiratory infection .
