I think the question is, how does one distinguish the claims above from the claims described in the article, such as "it was surmised that if he had eaten breakfast before picking up the scalpel, the food would have absorbed any poison attending the corpse"? IMHO the article disagrees with the parent; the article refers to honey as a relic of medical practices of Ancient Greece; I'd bet ours are far more effective. The article supports the idea that scientific method, publicly reproducible empirical evidence, is the tool to separate bad ideas from good, superstition from fact.
