Picrorhiza kurroa, commonly known as Kutki or Katuki, is a highly regarded herb renowned for its hepatoprotective properties and diverse pharmacological activities (1).
With a history of medicinal use dating back 5000 years, Katuki’s significance in traditional medicine is well-established. One of its key benefits lies in its ability to balance Pitta and Kapha, which aids in regulating acidity, digestion, and fat metabolism. By acting as a cooling agent, Picrorhiza kurroa helps remove excess fire energy from the body, leading to improved digestion and metabolism of carbohydrates, proteins, and fats (1).
Let’s delve deeper into the incredible benefits and uses of Picrorhiza kurroa and explore its therapeutic potential.
Ayurvedic Properties of Picrorhiza Kurroa
Picrorhiza kurroa is known as Katuki in Ayurveda. It is characterised by its Tikta (bitter) taste, Ruksha (dry) and Laghu (light) qualities, and Sheeta (cooling) potency.
