Placenta Power
According to Kentaro Yoshida, director of the Yoshida Clinic in Japan that specializes in dermatology and author of the book "Placenta Power," the Chinese have been using placenta as a remedy for aging skin and shiny hair for over 2000 years.
Yoshida also claims that placenta was employed as a heath treatment in Ancient Egypt and that Marie Antoinette used it as a beauty elixir (that's right, as a drink!)
