The species is used as herbal medicine for diseases and ailments such as abdominal pains, boils, fever, inflammation, malaria, rheumatism, swellings and tuberculosis and as ethnoveterinary medicine. Multiple classes of phytochemicals such as alkaloids, anthraquinones, essential oils, flavonoids, lignan, phenolics, sterols, tannins and terpenoids have been isolated from the species. Scientific studies on C. sylvaticus indicate that it has a wide range of pharmacological activities which include antibacterial, antifungal, anti-inflammatory, antioxidant, larvicidal and effects on the central nervous system. Although studies have confirmed that C. sylvaticus has a wide range of bioactives, further research on the exact bioactive molecules and mechanisms of action are required.
