Melissa - Rectified
GENERAL INFORMATION: Another solution to the prohibitive expense of melissa is to purchase a rectified melissa essential oil. This term indicates that a material was reprocessed or distilled a second time. Sometimes a rectified (or redistilled) oil will be added to an oil from a first distillation. This is not done to commit fraud, but to enable an oil such as melissa to be produced less expensively so that people will be able to afford to use it. These oils often have amazing healing properties, although the first distillation is always better.
There are also less scrupulous producers who break a variety of essential oils into chemical components and then reassemble them to closely resemble an oil that is either expensive or difficult to produce. The finished product is 100% biological and can be labeled "natural" (there is nothing natural about it). Sometimes these "fakes" are labeled rectified, although they shouldn't be. In this case, using melissa as an example, there may not have been any melissa oil used in the production of the finished product at all. This type of fraud is difficult - almost impossible - to detect by current testing equipment and standards. The difference will lie in how well they work. Being 100% biological originally does give these products some medicinal value but the fact remains that "only God can make a tree". Your own nose, the response of your own energy system, and buying from knowledgeable people whom you trust is your only protection from this type of criminal skullduggery.
