The Trotula, a medieval treatise on women’s health, includes certain weight-loss tips we may not want to apply today.
Trotula is the name commonly used to refer to a three-book compendium on women’s health (what we would today call gynecology), written in the 12th century in Salerno, by perhaps the most famous female doctor of the late Middle Ages, Trota De Salerno, physician and writer.
As usually happens in these cases, she only one wrote one of the three books in the compendium attributed to her. The authorship of the remaining two is still questioned.
