The term chamomile indicates some annual or perennial plants, of European origin, used in herbal medicine as a mild sedative and anti-inflammatory for external use. Among the most popular species of chamomile we mention Anthemis nobilis (also called Chamaemelum nobile), called Roman chamomile, and Matricaria chamomile, called German chamomile. These are small perennial plants, ground cover, with a stoloniferous development. They have light green foliage, from spring to summer they produce small flower heads, consisting of white petals and a golden yellow center. If the winter is mild they behave like evergreens; otherwise they lose the aerial part, which will sprout again in spring. In herbal medicine, flowers are used, which must be collected as soon as they hatch, and used fresh or dried.
Chamaemelum nobile plants prefer sunny or semi-shaded positions; they do not fear the cold and are present in the wild throughout the peninsula, along roads or in uncultivated fields.
This kind of plant prefers places where the winters are mild and there are no strong winds, an element that can compromise their health. It is important that the climate has a fair degree of humidity, even if this type of shrub is affected by the presence of an excessive amount of nighttime humidity.
