Tansy. Protective Herb, but only in one major area of life: it is commonly said to keep the Police, DEA Agents, or the INS from looking into one's affairs. A pinch of TANSY worn in the Shoes is said to Keep the Law Away, as does bathing in Tansy Tea, rinsing your clothing in water to which Tansy Tea has been added, or washing your floors down with the tea.
