How to Perform a Skin Patch Test

4:44 PM Posted by Jo Pedranti


 A skin patch test can be conducted with a carrier oil or with undiluted essential oil. A skin patch test should be conducted when using oils listed as potential sensitizers or irritants. Individuals with allergies or asthma should always conduct a skin patch test before applying any essential oils. Always use the recommended dose when conducting the skin patch test.

When conducting a skin patch test using essential oils diluted in carrier oils: You first wash and dry the forearm, then apply essential oil blend enough to moisten the arm. Cover the applied area with sterile gauze and leave for 24 hours If signs of irritation are shown, remove the gauze and avoid using that particular oil in the future.

When testing an undiluted essential oil, you wash the arm with unscented vegetable soap, and dry before applying the oil. Add one drop of oil in the crook of the arm and close the arm, and open and close the arm again after five minutes. If any irritation is noticeable, the applied area can be washed with cotton dipped in milk or vegetable oil. Or simply wash with soap and water.
