Æcerbot
The Æcerbot ([ˈæ.ker.boːt]; Old English for "Field-Remedy") is an Anglo-Saxon metrical charm recorded in the 11th century, intended to remedy fields that yielded poorly. == Overview == The charm consists of a partially Christianized prayer and a day-long ritual that began at night with four sods taken from the field, to the root-mats of which a poultice was applied in the form of yeast, honey, oil and milk mixed with parts of all the good herbs that grew, save buckwheat and woody plants.
