The Food and Drug Administration warned consumers on Tuesday that there's no proof that blood plasma infusions from younger donors can treat diseases, prompting one company that charges thousands of dollars for the service to halt the treatments, NBC News reported.
The company, Ambrosia, wrote in a statement on its website that it had "ceased patient treatments." It has been charging $8,000 for a liter of blood donated by people 16 to 25 years old during a clinical trial.
The FDA had said there is no proof behind companies' claims that young donors' plasma can treat conditions like Parkinson’s disease, dementia, or multiple sclerosis. But they may be dangerous, as they are associated with risks of infection or allergic reactions.
