If you are sensitive to supplements/herbs or have microbial overgrowth, you could experience side effects from mainly the Ultra Oregano. The Ultra Oregano can contribute to a Herxheimer or detox response. This is when a microbe like bacteria is killed off by something like Ultra Oregano and then the immune system comes to clean up the debris. In this process, a normal inflammatory response happens and is the first stage of healing. Common Herx/detox symptoms are general nausea, fatigue, headaches, neck pain, irritability, mood swings, gastrointestinal bloating, flu-like symptoms, constipation and/or diarrhea for the first 1-2 weeks while on the products. If you are sensitive, there are specific suggested instructions you will receive on how to start low, build up and find the dose that you feel works best for you.
