Tom's Comment

1. Sheng Di Huang is sweet and is often used a soup stock to nourish yin and fluids. It is often sold over the counter in many supermarkets
2. Sheng Di Huang is an excellent choice in treating heat in pediatrics because of its taste.
3. It is important to know how to tell the difference between Sheng Di Huang and Shu Di Huang. Sheng Di Huang has one brown side and one black side while Shu Di Huang are black on both sides.
