Chamomile is an annual herbaceous plant, about 60-70 cm tall. The flowers are gathered in flower heads formed by a conical and empty receptacle inside, on which small tubular and yellow flowers (hermaphrodites) are inserted, surrounded by a crown of ligulate flowers white (female). The fruits are very small, yellowish, slightly curved achenes, with 5 small ribs on the concave part. The flowering of the plant occurs from May to August; native to Europe and Asia, infrequent at altitudes above 300-400 m asl. Chamomile promotes digestive function and regulates gastrointestinal motility and has an emollient and soothing action on the gastro-intestinal mucosa. Useful in stomach acidity and reflux oesophagitis.
