I'm constantly amazed by the amount of people using essential oils neat on their own skin. This is especially common in the world of the multi-level-marketing (MLM) essential oils. Focus is placed on selling volume, and not nearly enough on the safety aspect of EOs. Useage of EOs neat is when their used undiluted on the skin.
Just today I saw a picture of a young boy, who had used a blend made to be used for ADD or ADHD along the spine undiluted in a roller bottle. The young boy had the hyperpigment(darkened skin) along his spine where the blend was used.
An example of photo-sensitization with essential oil:
The bottle was from a very large company, which also has no warning or dilution instructions. Lime is KNOWN to be phototoxic even in minute amounts, but there were no warnings nor mention on the companies website and pages about the oil. Not only is this unsafe its negligent in the simplest form.
http://www.naha.org/explore-aromatherapy/safety/ gives a great rundown on photo-sensitization
Photosensitizers (Table 3)
Angelica root Angelica archangelica Bergamot Citrus bergamia Cumin Cuminum cyminum Distilled grapefruit Citrus paradisi Expressed lemon Citrus limon Expressed lime Citrus medica Distilled orange Citrus sinensis Distilled tangerine Citrus reticulata Verbena Lippia citriodora
Non-phototoxic citrus oils (Table 4)
(FCF: Furanocoumarin Free)
Citrus bergamia Expressed grapefruit Citrus paradisi Distilled lemon Citrus limon Distilled lime Citrus medica Expressed sweet orange Citrus sinensis Expressed tangerine Citrus reticulata
Some oils depending on their method of distillation or expression, may fall onto either side of phototoxic, so be sure you know what your using.
All of this talk about the phototoxic oils really got me thinking about the overall safety aspect of dilution.
The normal "standard" dilution rate for an adult is 2 - 2.5%. 2.5% is 15 drops per 30ml(1 ounce) of carrier oil. 2% is 12 drops per 30ml(1 ounce).. For children, pregnant women, the elderly, immune compromised or pets, 1% is sufficent.
To get a better visual of just how powerful EOs are, and how much carrier is needed to safely dilute I created this graphic for another site. www.learningabouteos.com and the facebook group Learning about Essential Oils.
The numbers within the oil drops are the total amount of drops of essential oil. The bottles represent the amount of carrier.
|10 drops||1/10 tsp||1/60 oz.||1/8 dram||1/2 ml|
|12.5 drops||1/8 tsp||1/48 oz.||1/6 dram||5/8 ml|
|25 drops||1/4 tsp||1/24 oz.||1/3 dram||1 1/4 ml|
|50 drops||1/2 tsp||1/12 oz.||2/3 dram||2 1/2 ml|
|100 drops||1 tsp||1/6 oz.||1 1/3 dram||about 5 ml|
|150 drops||1 1/2 tsp||1/4 oz.||2 drams||13.5 ml|
|300 drops||3 tsp||1/2 oz.||4 drams||about 15 ml|
|600 drops||6 tsp||1 oz.||8 drams||about 30 ml|
|24 tsp||8 Tbs||4 oz.||1/2 cup||1/4 pint|
|48 tsp||16 Tbs||8 oz.||1 cup||1/2 pint|
|96 tsp||32 Tbs||16 oz.||2 cups||1 pint|
I dilute the commercial blends I use to 2% if they're undiluted, unless its a pretty severe acute issue needing an focused treatement then it may be up to 10%.
So now that your mind is all jumbled up with numbers, I'll make it easy.. Lets go back to that 10-15ml roller ball bottle used neat, how much blended diluted oil does that make? A LOT!
