Pathimugham, also known as Sappan Wood (Caesalpinia sappan), is a traditional herbal wood widely used in Kerala and other parts of India for preparing naturally refreshing herbal drinking water. When soaked or boiled in water, it imparts a pleasant pinkish-red colour and a mild woody flavour. Pathimugham has been a part of traditional wellness practices for generations and is commonly used as a natural beverage ingredient.
