Hydrazine sulfate-

is a disproven treatment for cancer and is now mainly used in alternative medicine for the treatment of nausea and vomiting from cancer.  One of the drug’s side effects is nausea.  This is one of the therapies that showed anecdotal promise but as more and more rigorous trials were conducted it became apparent it has no effects on cancer whatsoever.  This does not stop charlatans on the internet from making such claims, and the drug (called a “supplement”) is being sold online.  The side effects include difficulty in fine muscle control, inflammation of the nerves, dizziness, and rare liver and kidney failure. 

Painbytes assessment: scam therapy.  Two thumbs down.
