Several unorthodox drugs for healing cancer recommended widely in the USA and Hungary are discussed. Credulity plays a decisive role in the application of the drugs of doubtful effect and/or "remedies" that are undoubtedly without any effect. Typical examples are Krebiozen, Laetrile, Celladam and water with decreased deuterium concentration. In connection with Avemar, the most recent Hungarian remedy with so far clinically unproven physiological effect it is surprising why an expensive seminatural material is sold when the agen, in fact, is a well-known and synthetically easily available compound.
