I remember before my lap surgery they told me to stop taking any herbal treatments and vitamins.
It takes herbal treatments sometimes weeks to work, so you may want to try later (so it is not interrputed w/ surgery).
Also, Endometriosis can ONLY be diagnosed via surgery. You cannot see it in an ultrasound, so to prove your theory you would need mulitple lap surgeries.
On the other side:
The idea is that you do the lap surgery, cut out or laser the endometriosis, then start depo or BCP to keep it from re-growing. Endometriosis doesn't grow on BCP or depo. (To explain this you have to get into what hormones do to the body...)
I am different, I will not waste my time on herbal treatments. I want to use what works, but I was in so much pain I could not walk and could not wait for the herbal treatments to start working.
Good luck on deciding.
If you have any questions, let me know!
