05 May What is a “hot” oil?

Hot or caustic essential oils are considered warm and should ALWAYS be diluted. It’s also best practice to conduct a skin test for hot oils. Careless usage of hot oils can lead to extreme skin discomfort and mild burning.

Please note that if an essential oil is considered hot for topical use, it should also be used with EXTREME caution for aromatic and internal use. Do not inhale any of the listed hot oils neat as it can cause discomfort to your delicate membranes in the nasal passage.

I prefer a very conservative approach to dilution when it comes to hot oils. I suggest a ratio of 1:3, 5 or even 7 depending on your tolerance (so 1 drop of EO to 3, 5 or 7 drops of carrier oil). Remember, that dilution doesn’t make the oils work less, you are still getting the same benefit with perhaps more spread.

If experiencing skin discomfort from hot oils or ANY oil, never use water for relief. ONLY use carrier oil, milk or a good lotion.

Finally, please note that some cool oils can also burn hot, like Peppermint, Wintergreen, Eucalyptus so take caution when applying those topically as well and always dilute.

Here is a list of essential oils considered to be “hot”: Black Pepper, Cassia, Cinnamon Bark, Clove, Ginger, Oregano, Peppermint, Thyme, White Fir, Wintergreen and any blends containing these.
