What the label says
Microencapsulated peppermint oil appears as the final component of the 550 mg proprietary blend. The product label does not provide its individual amount or details of the microencapsulation system.
What microencapsulation generally means
Microencapsulation is a formulation technique that encloses small droplets or particles within another material. Depending on the system, it may be used to protect an ingredient, alter handling or influence release. Without product-specific technical data, it is not appropriate to claim a particular delivery advantage for Breathe.
What NCCIH says about peppermint oil research
NCCIH reports that peppermint oil has been studied most extensively for irritable bowel syndrome and some digestive symptoms. There is not enough evidence to assume those findings apply to respiratory outcomes or to the amount contained in Breathe.
Peppermint oil safety
Oral peppermint oil can cause side effects such as heartburn, nausea, abdominal pain and dry mouth. Concentration matters, and essential oils should not be used casually outside labeled directions. Follow the Breathe label and seek professional guidance when appropriate.
