Kutaja (Holarrhena antidysenterica) -
Kutaja powder is a simple formulation prepared from the stem bark of Holarrhena antidysenterica (Roxb. ex Flem.) Wall., a small to medium-sized tree, found throughout India. The stem bark is collected from 8-12 years old trees during the middle of rainy season (July to September) and again at the end of winter by hewing and peeling and separating it from the attached wood.
The stem bark is bitter in taste and used in Ayurveda for the treatment of gastrointestinal disorders, particularly diarrhoea and dysentery. Most of the Ayurvedic formulations described in literature and various commercially marketed formulations for diarrhoea essentially contain Kutaja as one of their ingredients. Kutaja is mentioned in the Indian Ayurvedic Pharmacopeias as well as Formulary. Apart from the preferred use of Kutaja in the treatment of diarrhoea, scientific studies have established its anti-protozoal, anti-giardia and antiamoebic properties.
