[A] “Hot oils” are oils that can cause a hot or warming sensation when applied to the skin. Examples of hot oils and blends include Cinnamon, Clove, Lemongrass, Oregano, Thyme, Exodus II, and Thieves. For some people, Peppermint’s cooling sensation can be too intense.
Young Living recommends using a patch test procedure prior to first use. To perform a patch test, apply 1–2 drops of essential oil to a patch of skin such as the forearm. Observe that area of skin over the course of 1–2 hours for any noticeable reaction; however, reactions occur usually within 5–10 minutes. If you experience a hot or burning sensation or develop a rash, add V-6 or another carrier oil to the affected area as often as needed.
