The species produces little drops of mucilage containing a sugary substance that lures its insect prey. Insects get caught in the sticky tentacles and are consumed by digestive enzymes. This carnivorous lifestyle has likely evolved in response to its nutrient deficient habitat - cool boggy areas of mountainous regions. Roundleaf Sundew has been found to have anti-inflammatory and antispasmodic properties, and has a long history of use as a medicinal herb for relaxing respiratory muscles and relieving wheezing and chest complaints, whooping cough, bronchitis and asthma. Although assessed as Least Concern at a regional level, Roundlead Sundew has a different conservation status according to the country in which it is evaluated showing various levels of threat to the species. In northwest Europe, many bogs have been destroyed due to human disturbance and activity, so it is imperative that sites supporting this habitat are protected in the future.
