Young Living owns their farms. They own their distilleries. They process their own essential oils. They test each batch of essential oils in their own laboratories and also in 3rd party laboratories. No other essential oil company can make that claim!
Why would cooking with essential oils be beneficial to your health? Because they are concentrated plant extracts! For example, one drop of Young Living peppermint oil is equivalent to 28 cups of peppermint tea. Dried herbs lose their medicinal properties. Bruce Taino of Tainio Technology in Washington has measured frequency of foods, the human body, essential oils, etc. It was found that dried herbs have a frequency between 12-22 MHz. Live herbs have a frequency from 20-27 MHz. The lowest frequency of an essential oil (Valor) is 47 MHz and goes as high as 320 MHz (Rose oil). Note that essential oils have higher frequencies than food! Since your body is a bio-electromagnetic organism, you want to ingest higher frequency foods in order to raise or maintain your frequency.
