Radam’s safety-and-mechanism claim was that the Microbe Killer is not a drug at all but charged water. In his 1890 book, as quoted by Barnett, he wrote that it “cannot be compared with ordinary drugs. It does not contain any of them. It is pure water, permeated with gases which are essential to the nourishment of the system, and in which micro-organisms cannot live and propagate, or fermentation exist,” to be taken until “the tissues shall be thoroughly soaked with it, and the blood becomes perfectly purified.” The claim is mechanism-only and refuted, and it is self-undermining. Radam’s own patent (US 412,664) shows the “gases” are the fumes of burning sulphur passed through water to a “sour acid taste,” that is, dilute sulphurous and sulphuric acid, which is also what R.G. Eccles found on analysis. A liquid dilute enough to drink safely by the glass cannot soak the tissues with a concentration that kills micro-organisms, and swallowed acid is neutralized in the gut rather than purifying the blood. The “harmless pure water” framing and the “kills all microbes in the body” framing cannot both be true, and neither describes a real therapeutic effect.
