Three common methods to recognize best Mulethi are
1. ‘Play with Fire’ to Know the Content of Bioactive Agents: Take a dried Mulethi root and burn it in the fire. If the flame glows blue and a slight drizzle is heard (like a green bush fire), it is a well-grown and dried Licorice (Mulethi). Licorice root, which burns like a normal wooden stick, is of poor quality. Our Mulethi would burn with a snort of blue. That is our assurance.
2. Water Test for Essential Oil Content: Crush a little Mulethi root and put it in a glass of water. Within seconds, the oily mixture will dissolve in the water and the root will sink within ten minutes. It is a symptom of rich essential oil containing Mulethi root. Our Mulethi possesses excellent essential oil content (Pur Mulethi essential oil yield is around 1.7-4.5%).
3. Physical Dimensions and Appearance: The best Mulethi root has a circumference of 30 mm to 45 mm approximately. There will be thin skin and a slightly rough fleshy part. When you rub, the dust will fall off like sugar-coated on the cutting edges.
