I don't think any female balancing herbs will cause a worsening of the endo., but I found that some of them caused me more pain because of their estrogenic qualities. You may first want to try to do the cleanses suggested here, and work on your bowel, and liver health. Tha liver is the master organ for metabolizing and excreting hromones, and if your liver is congested with bile and stones, you will have more problems related to hormones. Good luck!!
