Placenta: The Gift of Life by Cornelia Enning is really the only book of its kind. This book is chuck full of interesting facts about the placenta and specifically addresses the history of the placenta.
The author also explains medical uses of the placenta by country. Did you know the Chinese have been using the placenta for remedies for over 1,400 years? The United States was the only country that doesn't recognize any type of placenta medicine. It's sad really and hopefully in the future, this will change. I believe it has begun to.
Medical applications of the placenta are also discussed such as breastfeeding, newborn colic, childhood diseases, heart and circulatory system diseases, hair loss, scalp conditions, menopause, and midlife crisis.
The best part of the book is definitely the recipes for various remedies. There is discussion in the book on how to preserve the placenta and there are recipes for placenta ghee, placenta ointment, placenta, tincture, placenta bath, a lactation drink, placenta soup, placenta cream, and much more. There is a section on how to encapsulate the placenta, but from my knowledge I did find it a bit lacking. There were important steps I felt that were missed and the instructions are not detailed enough. Some of the other recipes, however, were wonderful.
