I spoke with my Chinese herbalist yesterday about my polyp and she said it was a symptom of imbalance of the kidney and recommended different types of herbs throughout my cycle (e.g. ones that treat kidney-yang deficiency after ovulation). They don't think in terms of 'estrogen dominance' etc, since that's a western term. It's such an individual experience and the herbs can be powerful. I would suggest seeing a TCM for a prescription.
