It has an appealing appearance, but it is a carnivorous plant. Its deep red
leaves and the small droplets that cover them are actually a death trap for
insects. The color attracts mainly flies and mosquitoes, and the droplets are
mucilages in which the insects are trapped for phagocytosis. This way, the

which have been known for centuries. In the 12th century, the Italian physician
of the Salerno School, Matthaeus Platearius, described sundew as an excellent
remedy for coughs, and so it was used in Europe and especially in Germany. Herbalists
recommended sundew tea for coughs, bronchitis, asthma and “bronchial cramps”. A
study already proved in the first half of the 20th century that
sundew does indeed have antitussive properties.

Nowadays, the roots, flowers and fruits of the plant are recommended because
