Yesterday, I posted that injured soccer player Robin van Persie flew to Serbia for a "placenta oil massage" he hoped would heal him. Apparently, the placenta treatment worked, but the Telegraph reports that it may have been more invasive than a massage: "The injection of horse placenta on to the affected area is claimed to speed up the recovery process and, while it is not known whether (teammate Yossi) Benayoun and Riera have been subjected to that treatment, both have returned to Liverpool ahead of schedule with their rehabilitation." (Thanks, Carlo Longino!)
