About Triphala Churna, In Ayurveda, charna is a mixture of powdered or blended herbs and minerals used as a cure for illness or illness. To make a charna, certain ingredients are thoroughly washed, completely dried, powdered and sieved. The resulting powder retains its potency for up to 1 year when properly stored in an airtight container. In general, the smaller the particles, the higher the absorption rate in the digestive tract, and the larger the particle size, which is advantageous as a medicine.
