How to identify genuine and fake essential oil?

 If the identify method of essential oil can be described with only a few words, then there is very few fake essential oil on the market. The key point is the essential oil type, character, molecular size and weight .the presented situation is not the same unless it is the synthesis of uniform characters of all essential oils.
For example: the molecular of the general grass is lightest, drop the oil in water, the oil spread quickly and float on the surface of water. But drop the resin molecular in water, you will find the entire drip sink to the bottom of the cup completely. it’s difficult to soluble in water, but it will be divided into two kinds of light oil and heavy oil molecules from the underwater and the surface of the water, however, the flavor has been filled with the whole cup of water.
Chamomile molecular is a special one among flower type which is also heavier than water molecules and do not dissolve in water, similar to resin, the entire drop sink to the water, and you can see crystal clear dark-green oil beads, that’s the reason different character are shown by the different Status.
In fact, your own nose has the capability to distinguish the authenticity of essential oils, 100% pure plant essential oils, smells complex, the fragrance is not visible. Each has different feeling. and the fragrance contain different feelings, such as: before flavor, in flavor and after flavor. it is so complex. But the synthesis essential oil smells pure not complicated, each ones’ feelings are similar.
Besides, color is one of the key points, such as Chamomile, There is a very valuable component in Chamomile “blue (huo Jing)", according to different origin have different qualities, smell is also different, Rome chamomile has sweet-smelling and strong flavor, showing dark green. The other one is the German Chamomile, also known as the German blue-Gan. Because of its color is dark blue, has a strong Chinese Medicine Smell. As readers reflected he had bought colorless one, and I can only say: "You are cheated. It was taking out of the valuable component blue (fire Jing) of Chamomile, and then sold to you.
Q: Does essential oil have expiration? It is the more aged, the more fragrant, right?
A: Anything will become old in nature, so everything has expiration, just different date. General speaking, essential oil has enough ability to anti-virus and anti-aging, because plant itself is a continuous derived process, any essential oil has such character-the more aged, the more fragrant. It has expiration just after use. Fruit type has the shortest shelf life because of its unstable molecule and easy transformation. Next is floral and grass. The wood is much stable, for it is enough to extract essential oil by a tree, the resin is the most stable among wood; pure essential oil is much easier to store, then blend ones. If floral blend with grass, or floral with fruit, the shelf life is a little shorter. If the blend oil mixes carrier oil, it has short shelf life after use, because such plant oil is easy to be oxydic. Essential oil also called plant hormone; it has the same substance and life energy with human beings. Essential oil has small molecule, high penetration, so it can effectively absorbed by human, no toxin left. According to research, chemical will remain in the body, essential oil is different from it, which discharged by sweat, breath and so on, For normal people, discharged time need 3 to 6 hours, for sick one, it also needs 14hours.
Q: Drip oil on the tissue, can we distinguish whether it is real or fake through smudge?
A: The method is not accurate, for essential oil, different type has different molecule, take grass for example, it has the smallest molecule, such as Lavender, Rosemary, Tea Tree, Lemon and Citronella can drop and smudge quickly on the tissue like water; while for wood, it has bigger molecule: Taiwan Cypress, flat Cypress, and Cider wood, all has a slower speed when drops on the tissue; Resin has much bigger molecule, more dense, it appears a in the water, it is hard to dissolve in the water, such as Frankincense, Sandal wood, Benzoin, Myrrh, not easy to smudge on the tissue.
