Also beware of essential oils. While some are relatively safe in small dosages, such as cinnamon and ginger, even peppermint can be toxic in anything but a small dosage. Certain essential oils such as eucalyptus and tea tree oil are in some formulations, yet these should never be taken internally. I use some essential oils(cinnamon, ginger,peppermint, oregano) however I use them in very small quantities(typically just 3 drops of each at a time once or twice a day mixed well in some water or coconut oil). Which essential oils are in the formula you are taking? How much of the mix do you take?
