<unk> , also known as<unk><unk>  injection or autohemotherapy, comprises certain types of hemotherapy using a person's own<unk>  (auto- + hemo- + therapy). There are several kinds, the original belonging only to traditional medicine, alternative medicine and some newer kinds under investigation. The original, unscientific form is "the immediate intramuscular or subcutaneous reinjection of freshly drawn<unk><unk> ". The other forms involve some change to the<unk>  before it is reinjected, typically oxygenation, ozonation (ozonated autohemotherapy), ultraviolet light exposure, or centrifugation. Forms include platelet-rich plasma (PRP) and<unk>  conditioned serum (ACS). It is not impossible that ozonated or UV autohemotherapy may have real efficacy and effectiveness in autoimmune diseases if they are immunomodulatory in some way (such as by interfering with the deranged autoantibodies), but this mechanism of action, if it exists, is not yet well understood, and it is also logical that whatever molecular changes the ozone and UV bring about are unlikely to act specifically on just the desired target molecules—meaning that risks are involved. Although<unk><unk>  donation and plasmapheresis are conceptually analogous, they are differentiated from<unk>  in the autohemotherapy sense of that term, having thoroughly scientific bases.
