Chamomile (Matricaria chamomilla) is the common name for several daisy-like herbaceous plants found near populated areas all over Europe and temperate Asia, and has been widely introduced in temperate North America and Australia. It often grows near roads, around landfills, and in cultivated fields as a weed, because the seeds require open soil to survive.
Chamomile has a branched, erect and smooth stem, which grows to a height of 15–60 cm, with long and narrow leaves. The flowers are borne in loose-clustered flower heads, with white petals and yellow centers, blooming in summer with a strong, aromatic smell. Of the many medicinal uses of chamomile, the most popular preparations include treating hay fever, inflammation, muscle spasm, menstrual disorders, insomnia, ulcers, gastrointestinal disorder, and hemorrhoids.
