What exactly is essential oil? My answer is "essential oil is the blood, hormones and even the soul of plants." We often say to take the essence and discard the dross. However, essential oil extracts the essence of essential oil and maximizes the function of plants. Different essential oils have different functional attributes. If we want to have a correct understanding of the characteristics and functions of each essential oil, we must understand the natural chemical properties they contain. Essential oil is extracted from different parts of plants, which is very natural and safe without messy artificial synthesis and chemical blessing. Plant essential oil contains more than 500 kinds of natural chemical components, and its main chemical components include four categories: terpene compounds, aromatic compounds, aliphatic compounds and other compounds. Its properties are extremely complex, and it is volatile, fragrant and highly concentrated. In addition, I would like to remind you: Except lavender and tea tree essential oil, pure essential oils should never directly touch the skin outside the palm, and even lavender and tea tree essential oil should not be directly applied to open wounds to avoid leaving brown marks. Natural chemical components contained in plant essential oils are important elements to maintain plant life, and they are called "the fifth life element of plants" or "the inherent nature of plants". Therefore, the "essential oil is the blood, hormones and even soul of plants" mentioned above was born. If we want to have a correct understanding of the characteristics and functions of each essential oil, we must understand the natural chemical properties they say they contain. The molecule of essential oil contains two elements: yin (negative) and yang (positive). Essential oils containing more positive elements are "exciting oils", while oils containing more negative elements are "calming oils". Some oils have these two properties at the same time, such as lavender essential oil, which can be both exciting and calming. Ok, that's enough for the introduction of essential oil. See you next time!
