Our era is twitchy: no matter where we go, no matter when, our senses are hammered by ringtones, vibrations, alarms, and sirens--whirls of images and video clips and ads. The resulting society-wide anxiety is the affliction of our time. While you could choose from dozens of corporate pharmaceuticals to calm your frazzled nerves, you could also try some little apples. This is the name given by the ancient Greeks to the spherical, golden, highly aromatic centers of chamomile blossoms.The ancients realized these morsels had healing properties and used them to treat fever, improve mood, and induce relaxation, in addition to using them in beer-making. In your own garden, you can experience these qualities simply by walking through a patch of chamomile in full bloom: its aroma is both heady and soothing, and its profusion of tiny blooms is truly beautiful.
