Radix Scrophulariae: Both Radix Rehmanniae and Radix Rehmanniae can clear away heat and cool blood, nourish yin and promote fluid production, and are used to treat diseases such as heat entering the blood, yin injury caused by fever, yin deficiency and internal heat, and so on. However, Scrophularia has a strong ability of purging fire and detoxifying, so the throat is sore and swollen, and phlegm-fire is more common; Rehmannia glutinosa is powerful in clearing away heat and cooling blood, so it is commonly used for bleeding due to blood heat and quenching thirst due to internal heat.
