Does Humulus lupulus leaf contain estrogen?
Is the estrogen of Hops in the leaf or in another part/s of the plant?

Thanks, 2A10:8012:19:AD67:9807:EAF6:E6B1:5A7B (talk) 21:38, 12 April 2023 (UTC)
 * Yes, and in strobili ("cones", i.e. hops).  --136.56.52.157 (talk) 23:28, 12 April 2023 (UTC)
 * To clarify, hops are from the "cone" part of the plant (Humulus lupulus); and for example, the leaves of the plant itself are not used for making beer. The leaf-like structures of the strobili are referred to as decussation; which, if I understand correctly, relates to their being a "cross" between a stem and a leaf. All parts of the plant (AFAICT) contain 8-Prenylnaringenin, considered to be the most potent plant estrogen (estrogenic phytoestrogen). --136.56.52.157 (talk) 03:26, 13 April 2023 (UTC)
