According To Culpeper, The Complete Herbal
Agnes Arber's Herbals: Their Origin and Evolution: A Chapter in the History of Botany, 1470-1670 (Cambridge University Press, 1938) surveys the printed herbals of that two-century period and documents how the doctrine of signatures, that a plant's form, colour or habit declares its medicinal use, a yellow flower for the Sun, a perforated leaf for light, a plant of wet ground for the Moon, was applied inconsistently from one compiler to the next. Comparing planetary and use attributions for the same plants across different herbals, Arber finds no agreement between authors, direct evidence the method is a theory of resemblance rather than one of observation or testing. Where a signature plant does have a real effect, as St John's Wort, willow and the poppy do, Arber traces that activity to the plant's chemistry, unconnected to its appearance. The instability she documents between compilers is why this atlas gives no single planetary attribution as settled.
