SAFETY
- Dilute essential oil with topical use. Topical use can cause skin irritation and contact dermatitis. Dilute with topical use and avoid mucus membranes, including nose, mouth, lips, and genitals. A safe dilution ratio is 1-2% in a carrier oil. This would equal about 6-12 drops in an ounce of carrier oil. Lis-Balchin indicates that 1 of 200 patients showed a topical irritation and/or sensitization to peppermint and advises a high dilution ration. From: Lis-Balchin, M. (2006).

Internal use can be very dangerous, with even just a few drops undiluted, having the potential to cause acute allergic response, asphyxiation, burning of the mucus membrane, and possible fatality in children (Lis-Balchin, 2006). Further, overdose of menthol, as with menthol cigarettes or candies, especially over a long period of time, has been known to cause severe gastrointestinal issues, convulsions, and blood dyscrasias (Lis-Balchin, 2006).
