Peppermint is brilliant for drifting thoughts and sore bodies. Peppermint's cool and clearing aroma is refreshing with minty layers of sweetness. Because this essential oil is high in menthol, Peppermint can help promote cooling, calming, clear breathing. Each oil from Candle Warmers is lab tested to ensure they’re 100% certified pure essential oil with no fillers. Airome ultrasonic diffuser sold separately.
