I am not certain about the use of the wonder of the world plant for the treatment of cysts (I presume ovarian?) and fibroids but I can tell you some natural remedies you can try.
Cinnamon helps to regulate circulation which helps with the pain that is associated with cysts. DIM is also a very good supplement that you can take to treat cysts and fibroids because it helps to balance hormones. Dong Quai also does this and some DIM supplements have Dong Quai included in the ingredients so it will help you immensely.
Cut back on dairy (especially cheese) because it tends to cause inflammation. Any extra inflammation in the body will cause discomfort and pain in the stomach when you have cysts or fibroids. Don't eat hard to digest foods like beef for the same reason.
Sweet potato is actually one of the foods that tend to be soothing to the stomach when faced with this malady.
For some people cutting out gluten helps considerably. You can try it for a month and see what happens. As a replacement, I would recommend buckwheat flour as that is easy on the digestive system as well.
Taking digestive enzymes and probiotics will also help to increase good gut bacteria and that is something you want to do to help the condition as well.
Consider taking milk thistle or dandelion to strengthen your liver. When your liver is functioning well then the body works well.
Don't do heavy exercise as long as you have ongoing pain but rather walk. Walking helps with the circulation but is not a vigorous activity.
