Wow!
In the last trimester, the placenta begins to secrete a corticotropin-releasing hormone, or CRH, which enables the mother to mentally and physically handle extreme amounts of stress; by the time of birth, most mothers have up to three times their pre-pregnancy levels of CRH[1] (or what we like to call the super-hero hormone).
I clearly remember wandering around my home in the postpartum period, unable to figure out how to accomplish my daily tasks because of an inability to act decisively in the presence of normal toddler activity, mess, and demands.
The ability to multi-task, overcome problems, and discover new solutions when obstacles arise are all skills directly affected by CRH hormones.
When the placenta is born, the feedback system that regulated the hormone’s production is interrupted, and the mother is left with only the CRH production of the hypothalamus. Because of this, postpartum mothers have low levels of this stress-fighting hormone making them more vulnerable to depression and less able to perform well under stress.
Studies from the National Institute of Health have found that consuming the placenta stimulates and stabilizes CRH levels. Endocrinologist George Chrousos, who led the NIH study, concluded that since the placenta contains large amounts of orally-active CRH, ingesting the placenta will stabilize CRH levels resulting in “a more stable emotional life for the mother.”[2]
