A Day in the Life of a Mom-Herbalist

This daily blog has been about the struggles of juggling motherhood with being a full-time student for the first eight months of its existence.  I still share some of my life now that I've graduated but I also share information each day on herbs that I've learned along this journey.   While my herbariums are listed for free membership, I provide four fields from them in my blog: Constituents (the active ingredients of the herbs), the therapeutic actions (Examples are expectorant and stimulant), indications (colds, skin rashes, emphysema, etc), and safety information. More information can be found in the herbariums but these are the most important educational fields.  I also share scientific studies to help educate people who think there are no studies showing herbs work.

Rosemary as a Phytoestrogen?

Zhao, Lee, Ma, Huang, Sun, Li, Chen, and Niu (2012) studied the effects of carnosol, an antioxidant on estrogen receptors. This is an attempt to find a solution to postmenopausal cardiovascular symptoms that do not bear a cancer-causing risk such as hormone replacement therapy.

Estrogen receptor a played a bigger role in this study that estrogen receptor b but it was clear that carnosol was effective overall in this study.  Carnasol played a significant role in reducing induced oxidative stress in a vascoprotective way.  Meaning, it prevented cell death caused by oxidative stress.  It displayed phytoestrogenic activity in BAECs. 

The estrogen receptors have also demonstrated antioxidant properties, especially estrogen receptor a which inhibited some of the carnosol activity. This study showed carnosol used the estrogen receptor pathway to exert its antioxidative properties.  However, the binding ability is different due to the structure of the phytoestrogen cells.  When the cells were pretreated with carnosol 24 hours prior to induced oxidative stress, the cardiovascular cells were not damaged by the oxidative stress. 

The authors of the study say there are existing studies which indicate daily intake if carnasol in animals is well tolerated.
 
Have a Great Day!
