According to Cunningham (from his Encyclopedia of Magical Herbs) Buckwheat can be used to form a magic circle on the floor around you while you are performing magic. Add some buckwheat to money incenses and keep some in the kitchen to guard against poverty. Handy to use in charms and spells to obtain treasure, riches, and wealth. Use to stuff poppets or create mojo/ spell bags or charms related to money or protection.
Buckwheat herb can be made into an infusion/ tea by steeping in hot water which can be added to your mop bucket to wash away negativity or to add to your bath for the same purpose. It can be used in its dry form to add to incenses, poppets, simmer pots for protection and money spells. .
