Phenol
In the past, the chemical phenol has been a medical and instrument disinfectant used in hospitals all over the world. It was also used by the inmate infirmary of the Auschwitz Camp for this purpose. The camp’s documentation contains several orders of phenol by employees of the infirmary (see Mattogno 2023, Part 1, pp. 140, 194, 249, 264, 282).
The orthodoxy claims that this phenol was used to kill severely ill inmates with injections into the heart. This is based on document forgeries by Auschwitz inmate resistance groups, and on misrepresentations and inventions by Polish historians, primarily Danuta Czech. See the entry on lethal injections for more details.
Nowadays, phenol has been replaced in most cases by other, more efficient disinfectants.
