The following tips will help in buying high quality essential oil:
After determining the proper oil from a qualified health professional, visit a genuine dealer of genuine establishments .Primary importance should be for the quality of the item than the cost.
Ask the vendor to provide free samples. This may help in testing or verifying the quality, at least to some extend.
Never purchase from vendors at street fairs. They will cheat by selling spurious, cheap products and then disappear.
Check for dust on the top of the bottles. This means oil has been there for quite sometime. It is but natural that as time passes, many oils lose their therapeutic properties, and their aroma decreases.
Do not be carried away by the phrase “pure essential oil”. It is misleading. Quality of the plant, the distillation processes, bottling, storage etc play an important part to guarantee the purity of the oil. The vender may have little idea about these.
Go for pure essential oils and not synthetic essential oils. According to aroma therapists, synthetic oils do not possess the same therapeutic properties as pure essential oils. Synthetic oils can cause headaches, allergic reactions etc. Synthetic oil can never match pure essential oil in quality.
Check the color of the glass bottle. It should be dark amber or blue. If it is clear or colorless, it can permit light to pass through, thereby decaying the oil.
Essential oil has chemical action with plastic. With the result, oil in plastic container gets contaminated. So avoid plastic bottles.
Aluminum bottles are acceptable with inside lining.
Rubber can dissolve and contaminate the oil. So refrain from buying oil with rubber eye dropper bulb on top.
Read carefully the write-ups. The label on the bottle should contain markings like “100% essential oil” or “pure essential oil”. Avoid “aromatherapy oil” fragrant oil”, “perfume oil” etc because they are not pure but mixed with other substances including chemicals.
Reputed companies put the Latin name of the essential oil on the bottle in addition to the common name for the benefit of the customer to avoid confusion. The write-ups should indicate the country of manufacture and method of extraction. The country of origin is important because properties of the oil considerably depend on the climatic and soil conditions of the country.
When you come across the same prices for different oils, it is an indication that oils are synthetic. The raw materials used, their availability, their quantity, method of extraction, all these factors affect the cost. Obviously, the cost of each essential oil varies.
Avoid products from companies that supply to the food & beverage industries.
Essential oils diluted with vegetable oils are to be avoided straightaway.
While sniffing the oil holds the bottle about six inches from the nose. If it is too close, the pure, strong, oil will affect your brain and cause headache.
Avoid comparing different brands of oils, scents etc continuously. Give some interval because the concentration will affect the senses such that you fail to notice the differences in the oils.
Last but not the least, check for expiry date, if any.
