In traditional Chinese medicine, Chai Hu Qing Gan Tang is highly valued for its ability to soothe the liver, clear heat, detoxify, and reduce inflammation. It is a go-to formula for treating excess heat in the liver, gallbladder, and triple burner channels, and is widely used for various inflammatory conditions, supporting overall health.
Chai Hu Qing Gan Tang originates from the Yiguantang school, though its exact source text is unclear. Based on its name and composition, it focuses on soothing the liver and clearing heat while also detoxifying and reducing inflammation.
It primarily targets excess heat in the liver, gallbladder, and triple burner. In Japan, it is often used for children with liver heat tendencies, treating conditions like neurosis, chronic tonsillitis, and eczema.
Formula Explanation of Chai Hu Qing Gan Tang
Chai Hu Qing Gan Tang is a skillfully crafted formula, combining elements of Wen Qing Yin (Huang Lian Jie Du Tang plus Si Wu Tang) with herbs to disperse wind-heat:
Monarch Herb: Chai Hu. Used in a large dose, Chai Hu soothes the liver and guides the formula to the liver channel, addressing excess heat in the liver, gallbladder, and triple burner.
Supporting Herbs: Huang Lian, Huang Qin, Huang Bo, Shan Zhi Zi (from Huang Lian Jie Du Tang). These assist Chai Hu in clearing heat and detoxifying, targeting all types of heat-related conditions.
Assistant Herbs: Dang Gui, Shao Yao, Chuan Xiong, Sheng Di Huang, Lian Qiao, Niu Bang Zi, Jie Geng, Bo He Ye, Tian Hua Fen (Gua Lou root). Dang Gui, Shao Yao, Chuan Xiong, and Sheng Di Huang nourish and activate blood to soften the liver, with Sheng Di Huang chosen for its strong heat-clearing effect; Lian Qiao and Bo He Ye disperse wind-heat and reduce inflammation; Niu Bang Zi and Jie Geng clear wind-heat, detoxify, and ease the throat, aiding phlegm or pus expulsion; Tian Hua Fen clears heat, dissolves phlegm, generates fluids, and soothes inflammation.
Envoy Herb: Gan Cao. Gan Cao harmonizes the formula.
Pathogenesis Analysis of Chai Hu Qing Gan Tang
Chai Hu Qing Gan Tang targets excess heat in the liver and gallbladder channels, with a complex pathogenesis involving multiple interacting factors that produce various clinical symptoms.
Liver Channel Stagnant Heat
Emotional stress, poor diet, or external pathogens can cause liver qi stagnation, which over time turns into heat. The liver regulates qi flow and prefers smooth movement, disliking obstruction. Stagnant liver heat impairs its regulatory functions, affecting digestion, blood flow, and emotions, leading to chest or flank discomfort, mood swings, and a bitter, dry throat.
Wind-Heat Invasion
Wind-heat pathogens entering through the nose, mouth, or skin can combine with internal heat, worsening heat symptoms and affecting the liver and gallbladder channels. Wind-heat disturbing the head may cause headaches or tinnitus; in the throat, it leads to sore throat or tonsillitis; when combined with damp-heat, it can cause itchy skin or eczema.
Accumulated Heat Toxins
Prolonged heat accumulation can develop into toxic heat, which is highly damaging. It consumes qi, blood, and fluids, causing localized inflammation, pain, or even abscesses. In the liver and gallbladder channels, toxic heat may lead to flank pain, jaundice, or liver enlargement.

It is also suitable for children with nervous temperaments, swollen neck lymph nodes, and recurrent tonsillitis or sore throat.
