Auto Sanguine therapy

Could you please assist and advise if the following is permissible? In Homeopathy, there exists a therapy called Auto Sanguines therapy. This involves taking some of a person's blood and creating a medicine with it, which is taken orally. Is this permissible?

The definition of Auto Sanguine is: In Auto-sanguis dilution therapy, small doses of the patient’s blood are prepared as a homeopathic remedy. The effectiveness of this therapy is rooted in the homeopathic principle that small doses of a substance reverse symptoms caused by large doses of the same substance. People who suffer form an autoimmune disease have elevated levels of pro-inflammatory agents, antibodies, and circulating immune complexes in their bloodstream, all of which are involved in the abnormal immune response. A homeopathic mixture containing minute traces of these substances can reduce or even completely eliminate the autoimmune response. Autosanguis therapy simply means using blood from a patient as a medicine to treat a condition that that patient is suffering from.
