Roman chamomile originates in northwestern Europe and northern Ireland, where it creeps close to the ground and can reach up to one foot in height.  Gray-green leaves grow from the stems, and the flowers have yellow centers surrounded by white petals, like miniature daisies.  It differs from German chamomile in that its leaves are thicker and it grows closer to the ground.  The flowers smell like apples.

Chamomile teas, ointments, and extracts all start with the white and yellow flower head.  The flower heads may be dried and used in teas or capsules or crushed and steamed to produce a blue oil, which has medicinal benefits.  The oil contains ingredients that reduce swelling and may limit the growth of bacteria, viruses, and fungi.

Traditionally, Roman chamomile has been used to treat nausea, vomiting, heartburn, and excess intestinal gas.  It is widely valued for its anxiety-relieving properties.  Used topically, this herb may also reduce inflammation associated with cuts or hemorrhoids.  It may ease the discomfort associated with conditions such as eczema and gingivitis (swollen gums).

Test tube studies have also shown that chamomile has antibacterial, antifungal, and antiviral properties.  Chamomile has antispasmodic properties, meaning it helps relax muscle contractions, particularly in the smooth muscles that make up the intestines.
