Tests and Standards for Therapeutic Oils

Do you want to assure Butterfly Express essential oils are pure, potent, and therapeutic? Below you will learn how Butterfly Express uses high integrity practices to produce quality oils. Understanding industry tests and standards is also important in understanding how Butterfly Express chooses suppliers and produces therapeutic grade oils. In short: they don’t play industry games; instead they use science, intuition, and pure intent to create great essential oils.

Read this article to glean more information and understand how (and why) Butterfly Express makes quality essential oils that are affordable.

From Certified Pure to Affordability: What makes Butterfly Express oils so special

Testing and standards of essential oils is very complex

In the video (see below), LaRee Westover, founder of Butterfly Express and herbal/essential oil expert states:

“Many of the most important compounds for aroma and therapeutic value are in infinitesimally small amounts, literally trace proportions. Though small in proportion…these trace elements play an absolutely essential role among the multitude of components in [essential] oil.”

Chemist in laboratories the world over with all of their high tech equipment cannot and have not ever created a credible list of all the ingredients found in even one bottle, of one basic essential oil, let alone accounted for variations in growing conditions and harvesting and processing methods. The technology…simply does not exist for such an endeavor.”

So why all the hype about testing standards? Granted, I see the reasoning to have a measure of quality in many instances. But as LaRee pointed out, it is impossible to create a good technology based standard for essential oils.

ISO Standards and Common Commercialized Oil Practices

ISO Standards (the most common) for essential oils may be incorrectly correlated with the therapeutic benefits of various oils tested. In other words, it would be unwise to assume that an essential oil is therapeutic and offers health benefits because they fall within ISO, or other trademarked, parameters.

Marge Clark, owner of Nature’s Gift, had two samples of peppermint independently tested, one from the US and one from India; the results offered some interesting insight between her two samples:

The ISO standard is based on a rectified oil, designed for large quantity commercial grade oils. Our USA midwestern peppermint is exactly that, a commercial grade oil. It passed. The Indian oil is unrectified, straight from the still, what aromatherapy practitioners claim to want. The ISO specifications are designed for commercial grade oils, not pure, natural unrectified oils. We have a commercially produced rectified product that passed with flying colors and a certified organic small (boutique) producer whose essential oil did not. I would hope your readers can draw their own conclusions.

Interesting, yes? This bit of research confirmed what I knew in my heart: I can trust my nose, my body’s response, and my God to know what essential oil is right for me and my family. I give everyone this right, celebrating when anyone uses essential oils, and hope to educate them to trust themselves and not an organization.

What is a “rectified oil”? For some commercial grade oils, when essential oils are first distilled they are rectified with a specialized vacuum to improve smell and remove unsatisfactory, like weedy, overtones. This is a common practice to produce a smell that is consistent from bottle to bottle. Pure and natural oils straight from the still are not rectified. In nature, nothing is consistent and the constituents of a plant will be a bit different with each essential oil batch. So do not fear if your favorite peppermint has a slightly different “flavor”. Enjoy it and be grateful! Butterfly Express works directly with trusted “boutique” companies/farms that follow organic practices, some which they’ve worked with for several decades, that produce true therapeutic grade essential oils that are NOT rectified.

In short, testing standards do not provide a correct picture of purity and potency. Rest assured, Butterfly Express buys pure and therapeutic essential oils that have been tested and proved as such, as far as possible. They are very picky about their suppliers. However, understand that the true therapeutic nature of essential oils cannot be proven by testing. As a second precaution, Butterfly Express personally tests essential oils from suppliers before it is bottled, labeled, and shipped (see article below). The quality of Butterfly Express essential oils is mostly proven in the experience of our customers.

Science of Essential Oils and Butterfly Express

Watch LaRee Westover, founder of Butterfly Express and herbal/essential oil expert, shares her credentials and teach about essential oils in the video; you will receive an in depth understanding about the science of essential oils! It helps to show just how much she loves and understands essential oils, which are representative in how she chooses her suppliers, makes blends, and runs Butterfly Express: a family business. (For instance: Anyone having a bad day is asked to work somewhere else other than with essential oils. The intent of the oils is pure because of many practices like this.)

For more information about testing and standards, as well as how Butterfly Express chooses it’s suppliers and conducts their own testing, read the following article from the book “Butterfly Miracles with Essential Oils” by LaRee Westover.
