Lemon Verbena (Aloysia citriodora) is a great detox tea. It also calms digestion and relaxes the mind and body. The leaves have an intoxicatingly lemon scent and dried they keep their taste for many months. The flowers make a dainty garnish. An herb well worth growing in your garden but it is frost tender. When cooking a chicken or fish pick some leaves of the lemon verbena and pop in cavities to give a lemon flavour to your dish.
