The rhizome has a long history of use in Indian Ayurvedic medicine for the treatment of digestive problems. Other uses have been proposed (e.g. for asthma, liver damage, wound healing, vitiligo) but the medical evidence is not yet conclusive. It appears to be relatively safe based on its long history of traditional use.  our study ARKA AAYURVEDA Current research on Picrorhiza kurroa has focused on its hepatoprotective, anticholestatic, antioxidant, and immune-modulating activity. Kutki has hepato-protective properties and thus supports the liver and spleen. It is used in all forms of liver damage, cirrhosis and inflammation of the liver. It protects the liver against damage from the hepatitis C virus.it is use to cure fractures
