"There is no proven clinical benefit of infusion of plasma from young donors to cure, mitigate, treat or prevent these conditions, and there are risks associated with the use of any plasma product," the FDA said in a statement from Commissioner Scott Gottlieb and Peter Marks, head of the agency's biologics center.

The idea of infusing young blood to fight aging has attracted technology entrepreneurs like billionaire Peter Thiel. [...]

"We're concerned that some patients are being preyed upon by unscrupulous actors touting treatments of plasma from young donors as cures and remedies," Gottlieb and Marks said. "Such treatments have no proven clinical benefits for the uses for which these clinics are advertising them, and are potentially harmful."
