Jiuzhi Huangjing is made from raw Huangjing by repeated steaming and drying, and can be taken in decoction, boiled in paste, or put into pills or powder. Huang Jing has a sweet flavor; it is flat in nature. It belongs to the spleen, lung and kidney meridians. Its effects are nourishing Yin and tonifying Qi, strengthening the spleen, moistening the lungs and benefiting the kidneys. It is used in treating weak spleen and stomach, tiredness and fatigue, internal heat and thirst (internal heat accompanied by excessive eating, drinking and urinating), dry mouth and little food, lung deficiency and dry cough, and deficiency of essence and blood. After steaming, the side effect of irritating the throat is removed and the tonic effect is enhanced. Adverse effects or contraindications of Huang Jing are not known. If medication is needed, it should be used correctly under the guidance of a professional Chinese medicine doctor, and should not be used blindly on its own to avoid adverse effects.
