Can Scrophularia root (Xuan Shen) treat pharyngitis?

It is generally used as an adjunctive therapy to help improve the condition, as Scrophularia ningpoensis has effects such as clearing and reducing excessive internal heat. Patients should regularly consume fresh vegetables and fruits, such as Chinese cabbage, spinach, apples, bananas, and pears. They should also drink plenty of water—Scrophularia ningpoensis can be steeped in hot water for consumption, as can honeysuckle or fat sea beans (Sterculia lychnophora). Spicy and irritating foods should be avoided.
