The present disclosure describes a study of estrogenic activity present in various plant species, selectively inducing some but not all estrogenic responses in the uterus. Prepubertal female rats were treated sequentially with various extracts or decoctions of different plant species or its vehicle, followed 1 h later by treatment with estradiol-17β (E) or its solvent. Uteri were excised under anesthesia and histologically processed for eosinophil quantification and morphometric evaluation of various uterine responses to estrogen, at 6 or 24 h after hormone or vehicle treatment. Besides extracts or decoctions, pure phytoestrogens were also used. Additionally, human mammary cancer cells MCF-7 or MDAMB-231 were cultured in presence of the extract (or decoction), E, both or solvent and cell proliferation was evaluated. Various extracts or decoction displayed selective estrogenic and / or antiestrogenic action for some but not all parameters of estrogen stimulation in the uterus and inhibited growth of human mammary cells in culture or antagonized the estrogen-induced increase in their growth. Present results reveal, for the first time, a dissociation of responses to estrogen by phytoestrogens, suggesting its possible therapeutic application as estrogenic compounds not inducing cell proliferation and reveal the anticancerous effect of some of the extracts with possible therapeutic relevance. The dissociation of responses to estrogen additionally suggest therapeutic applications in estrogen-related diseases (for instance, premenstrual syndrome, endometriosis, etc.); the inhibition of eosinophil degranulation suggest an application in diseases related to eosinophils (hypereosinophilic syndrome, allergic and hypersensitivity diseases).
