In the PCOS webinar, you state that the herbal formulas are all safe to take with metformin, but I've noticed in my reference materials that a couple of the herbs in the formula for non-weight-gain PCOS patients (bai shao and li zhe he) can create an herb-drug interaction with anti-diabetic pharmaceuticals, potentially causing hypoglycemia. Should I be concerned about this? I have a thin PCOS patient who is on metformin despite having a normal blood-sugar level without it. She is hesitant to start the herbs because of this possible synergistic interaction with the metformin. What precautions do I need to take with metformin patients who use these herbs?
Thank you for your advice.
