The name Chamomile or Camomile (from Greek χαμαίμηλον - chamaimēlon) means "earth-apple", from χαμαί (chamai) "on the ground" + μήλον (mēlon) "apple", because of the applelike scent of the plant. It can refer to any of several distinct species in the sunflower family (Asteraceae): The Chamomile flower is most often consumed in the form of a bitter herb tea infusion. Taken internally, the infusion's effects include calming of the digestive tract, and easing of the spasms of irritable bowel syndrome, nocturnal cramps and period pains. It's a relaxant and sedative, so it is often taken against insomnia or anxiety. The infusion can be used externally to reduce minor skin irritation because of its mild antiseptic effect and it lightens the hair. Ingestion of the dried flowers has an emetic effect.
