I drink Fennel Tea from time to time and Fennel as a vegetable is recommended in a few forum topics, books.
However I just googled some info on fennel and it seems that fennel contains Phytoestrogens, and is progesteronic. It is even used to aid breastfeeding in pregnant woman.
“Fennel contains anethole, which can explain some of its effects: it, or its polymers, act as phytoestrogens. [SNIP]”
It is listed as progesteronic on http://www.T-Nation.com/readArticle.do?id=462198
The same is true for some other herbs like Anice
Is this something to worry about and would it be better to avoid fennel?
