[Comment] Huangbai, Huangqin and Huanglian are all bitter and cold medicines, which can clear heat, dry dampness, purge fire and detoxify. But Phellodendron chinense can purge kidney fire and reduce deficiency heat, and can remove damp heat in the lower part of the body; Scutellaria baicalensis is good at clearing lung heat and can calm the fetus; Coptis chinensis can purge heart fire and eliminate restlessness, and is good at stopping vomiting. This is the difference between the three medicines. Therefore, the general saying that Scutellaria baicalensis treats the upper part of the body, Coptis chinensis treats the middle part of the body, and Phellodendron chinense treats the lower part of the body is based on the characteristics of Scutellaria baicalensis clearing lung fire, Coptis chinensis stopping vomiting, and Phellodendron chinense purging kidney fire. However, now in clinical use as heat-clearing and detoxifying drugs, Scutellaria baicalensis, Coptis chinensis, and Phellodendron chinense are all universal, without such strict distinction as mentioned above.
