Essential oils may help to reduce toxicity by promoting the detoxification of your home and body. These days, we are all inhaling and ingesting a number of chemicals and environmental toxins that can be dangerous for our health. Some work as mild diuretics, thereby increasing urine production and improving detoxification. And some oils aid digestion and promote the detoxification of toxins that buildup in the body. (18)
Oils with standardized content of components (marked FCC, for Food Chemicals Codex) are required[by whom?] to contain a specified amount of certain aroma chemicals that normally occur in the oil. There is no law that the chemicals cannot be added in synthetic form to meet the criteria established by the FCC for that oil. For instance, "lemongrass essential oil must contain 75% aldehyde to meet the FCC profile for that oil, but that aldehyde can come from a chemical refinery instead of from lemongrass."  To say that FCC oils are "food grade" makes them seem natural when they are not necessarily so.
Whilst this can seem confusing, the best advice for oil selection is to test which scents you like the smell of, because the ones your body needs tend to show themselves as the ones you like! This can change daily depending on your healing needs at the time. On our website, you can read a description of the scent and learn more about the properties of the oils and their therapeutic effects. Check out the ‘Safety Notes’ before you use them and check with your GP if you are pregnant or have more serious conditions such as epilepsy or blood pressure problems.
There are two ways that essential oils can enter the body to create an effect: they can either be absorbed through the skin or inhaled through the nose. Through the skin, the molecules enter through the hair follicles, sweat glands and fat molecules on the skin, entering your lymphatic and blood systems to get circulated around your body, going to the places they are needed most. Inhaling an essential oil gets the essential oil molecules into your body via your olfactory system (sense of smell) and limbic system (the emotional part of your brain) – going to the brain and your respiratory system. Once in the body, they work their way to where they are needed and where they can begin to trigger healing: in a similar way to how taking a pain-relieving tablet works.
