RECEPT contains peppermint oil. Peppermint is traditionally considered a "hot" oil, as it's cooling sensation for those with sensitivities can sometimes be perceived as burning. The term “hot” oil comes from the sensation an essential oil gives if used topically. These so-named "hot" oils can also give a spicy burning sensation when taken internally. Peppermint can border between hot and warm, depending on the individual, and can be overwhelming for some sensitive groups, such as children and elderly. PrimeMyBody has taken great care to ensure safe manufacture in adding the peppermint oil ingredient to its RECEPT formulation. Nonetheless, some people may still have a heightened sensitivity. For those with peppermint sensitivities, we recommend starting at a lower dose and titrating up as tolerance may allow. If you experience discomfort, try diluting with water or drinking plenty of fluids. It will not affect the efficacy of the RECEPT formulation. Some consumers may wish to discontinue use. As always, we recommend you consult with your physician or qualified medical professional before taking any supplement.
