Even with all the benefits, it is still important to know some words of caution to avoid the unwanted side effects caused by the incorrect use of menthol oil.

• Menthol oil should be used sparingly, especially for people who tend to experience allergic reactions, to avoid skin itching and redness.

• Pure menthol oil is highly concentrated. It should be used with a carrier oil before applying directly to your skin.

• People with high sensitivity should be cautious in using menthol oil to avoid adverse reactions.

• Seek immediate medical advice for any allergic reaction, if a skin reaction or swelling occurs or if accidentally ingested by a child.
