I am new to essential oils, our family had decided we wanted to try and incorporate them into our life for a more holistic approach and eventually weed out some of the meds in our medicine cabinet. On Saturday night woke with a horrible headache and put some peppermint oil on my temples and back of my neck for relief. Today I put a few dabs on my chest to get rid of heartburn. After doing this I saw online that peppermint oil can cause a miscarriage, does anyone know if this is the case or if that would be considered if you were to use it in mass quantities? I am almost 11 weeks so I am approaching my 2nd trimester but I wasn't sure.
