The chemical composition of the plant has been insufficiently studied. However, the plant is known to contain <0.05% alkaloids and flavonoids (the bioflavonoid kaempferol and the flavanol quercetin).
Medicinal properties are related to the chemical composition of the plant. Kaempferol glycosides, according to researches, have many pharmacological properties. They produce cardioprotective, anti-inflammatory, antimicrobial and analgesic effects, and also have antioxidant activity. Recent animal studies also show antidepressant effects of flavonoids. Quercetin - one of the most studied flavonoids, is also endowed with antioxidant and anti-inflammatory effects. The analgesic effect is provided by alkaloids.
