I. Extraction method
1, water distillation
Water distillation is to put the material to be distilled on the sieve plate of the distillation pot, and pour clear water under the sieve plate, so that the liquid level of clear water does not touch the material. You can directly heat the water in the pot with fire to generate steam to achieve the purpose of distillation.
2. Cold pressing method
Cold pressing is an extraction method to extract essential oil by squeezing peel manually or mechanically. Most citrus essential oils, such as oranges, bergamot, grape sleeves and lemons, are extracted by this method, because most citrus essential oils can't resist the heat of distillation and will destroy their essence in the process of extraction. At present, the extraction of peel essential oil is mostly replaced by mechanical cold pressing.
Second, the method of use
1, massage absorption method
After cleaning skin, spray Wei Yi plant essential oil on shoulders, neck, elbows, knees and other body parts for massage. When massaging, the intensity can be changed as needed. Faster and heavier massages, such as rubbing and slapping, can boost the spirit. Gentle touching and pressing will help us relax.
2, bath absorption method
After a busy day, the most comfortable thing is to take a hot bath and soak your feet. Wei Yi plant essential oil can also be used for bathing or soaking feet. It should be noted that because essential oil is insoluble in water, it can be dripped into bath salt and then mixed with hot water.
Matters needing attention
1, essential oil must be diluted.
Most high-concentration essential oils must be diluted when used. Essential oils in direct contact with skin can be diluted by adding vegetable oil. Of course, pure essential oils can't be applied directly. Generally speaking, except phenolic essential oil, it is no problem to apply a small amount of one or two drops. You can use pure oil when it is inconvenient to adjust oil, but you can't get into the habit. Don't use too much at a time. It is best to use lavender essential oil and tea tree essential oil as pure oil.
2. Make sure that the bottle is clean after each use.
When we pour the essential oil, we should pay attention to whether the essential oil flows out. If the essential oil flows out of the essential oil bottle, it may pollute your hands, so make sure that the bottle is clean after each use. If the bottle is not clean, we can wipe it with a rag to keep it clean. Because sometimes when we pick up the essential oil bottle, the essential oil does not flow down, but the edge will be polluted by the essential oil and our hands will be dirty.
