Vervain and dill
Hinder witches of their will.

If you thought dill was just for pickles, think again! Planted in the spring in a well-drained, sunny spot, this fast-growing member of the carrot family will yield a fine summer harvest. The delicate, ferny leaves lend a refreshing tang to potatoes, omelets, carrots, and cucumbers. The aromatic seeds are great with cabbage, fish, soup, and breads. Got witches? Pour them a cup of dill tea, which is said to rob them of their will to harm—a bit of ancient folklore which might have its roots in dill's enduring reputation as a sleep aid. In fact, the word dill comes from the Old Norse word dilla, meaning "to lull into sleep."
