Introduction

Kutaja is a well-known medicinal herb in Ayurveda, highly valued for its effectiveness in treating digestive disorders, especially diarrhea and dysentery. Native to India, it has been used for centuries in traditional medicine to support gut health and restore balance in the digestive system. The bark and seeds of the plant are mainly used for medicinal purposes.

In Ayurvedic medicine, Kutaja is considered a potent herb for restoring balance in the digestive system.
