Herbs such as *Chrysanthemi Indici Folium et Flos* (Juhua Ye, 菊花叶) and *Xanthii Fructus cum Cauliculis* (Canger Cao, 苍耳草) are used. Generally, once a Ding sore (Ding Chuang, 疔疮 - a type of acute suppurative infection with deep roots) has formed pus, the pathogenic toxin has been expelled outward, and there is no need to worry about other complications; however, extreme caution is required during the initial stage. If the Ding toxin attacks the Heart, disaster can occur in an instant. This is because Ding sores arise from the accumulation and knotting of Heart Fire, resulting in exceptional pain and extremely rapid harm. A diagnostic sign is that if the patient chews raw beans but does not perceive the fishy smell of the beans, it indicates this condition. Ding sores occurring within one cun radius behind the ear are particularly severe, representing the extreme state of枯竭 of Water and blazing of Fire (Shui Ku Huo Chi, 水枯火炽). They must not be treated recklessly.
