Mixed Methods Approach To Assess ‘Placental Opioid-Enhancing Factor’ Activity Within ‘Alternative’ Health Contexts Of Human Maternal Placentophagy, Jacob C. White

UNLV Theses, Dissertations, Professional Papers, and Capstones

Rats with elevated opioid levels experience an even greater increase in pain threshold after placenta or amniotic fluid consumption via placental opioid-enhancing factor (POEF) in the afterbirth. POEF only enhances opioid hypoalgesia; it cannot produce hypoalgesia alone. Although the POEF molecule remains unidentified and its efficacy in humans is unknown, it could be a safe, novel pain treatment. People who consume placenta as an alternative postpartum health practice are ideal for testing POEF bioactivity. Though rat models show that bioactive POEF is highly sensitive, some forms of the practice in humans may conserve POEF.

This project is the first attempt …
