Inflamed skin is often more permeable to essential oils and may be more sensitive to dermal reactions. It is potentially dangerous to put undiluted essential oils on to damaged, diseased or inflamed skin. Under these circumstances the skin condition may be worsened, and larger amounts of oil than normal will be absorbed. Sensitization reactions are also more likely to occur.

The signs of inflammation are redness, heat, pain, swelling and reduced function. The area that is inflamed will only be made worse with massage because more blood will travel to the area.

Some examples of acute inflammatory conditions are rheumatoid arthritis, bursitis and tendonitis.

Studies have found that the following essential oils had anti-inflammatory properties and reduce inflammation: apply diluted essential oil directly to the affected area to help reduce swelling and pain.
