This study is the first to report on the presence of oestrogenic compounds in different clover flower nectar samples. in bee-deposited nectars collected from hive combs (unripe honey) and in mature honeys harvested from the same hives. The clover species investigated were two red clover (Trifolium pratense) cultivars. bred specifically for high isoflavone content. https://parisnaturalfoodes.shop/product-category/baking-soda/
