Originator of the hormesis concept: Rudolf Virchow or Hugo Schulz

Abstract

In 2006, Henschler disputed the claim of Calabrese and Baldwin that Hugo Schulz should be considered the originator of the hormesis concept. Henschler cited an 1854 paper by Rudolf Virchow on the effects of two agents on the beating of cilia, which showed a hormetic–biphasic dose response. The interpretation of Henschler became broadly accepted over the past decade based on citations in the literature. However, a recent translation of the Virchow paper from German into English reveals that the claims of Henschler are not supported by the article.
