Research Gist
Kutki (Picrorhiza kurroa) is a Himalayan herb with a long history in Ayurveda, particularly for digestion and liver health. This comprehensive review brought together research on its traditional uses, chemistry, pharmacology, dosing and safety. The herb contains a range of active compounds, including iridoid glycosides, cucurbitacins, phenolics and terpenes. Its best-studied constituents are picroside-I and kutkoside, which together make up a large share of the plant's ethanolic extract and have shown strong liver-protective activity in preclinical studies. The review summarises research showing protection against several liver stressors, including alcohol, paracetamol and certain toxins, alongside antioxidant and anti-inflammatory activity. The authors note that no major adverse effects have been reported for the plant. In Somna Anu, Kutki's role is supportive — helping the body manage oxidative and inflammatory load rather than acting directly on sleep.
