phytoestrogens

I just wondered if anyone knows of a reliable list of herbal and natural medicine that DO NOT contain any phytoestrogens. That would be flavonoids, lignans, coumestans, etc. I know how much crap there is about this stuff online, but I’m just looking for a list based on whether medicines have them or not. And I know they have a lot of benefit, but everyone is different and this is mostly for informational or experimental reasons.

I don’t think you’re going to find a herb or natural medicine that doesn’t contain some form and quantity of phytoestrogen unless it has been genetically modified.

I can’t find any lists for medicine but there’s plenty on food and drinks.

Are all flavonoids phytoestrogens? I don’t think that is the case. As far as I know only some prenylated flavonoids are phytoestrogens.
