Huang Jing is generally prescribed in traditional Chinese medicine that a day’s dosage should be controlled at 9 to 15g, mainly for diseases such as deficiency of qi and yin in the spleen and stomach. As a rule, the maximum consumption of about 15g a day, but the specific dosage should be determined under the guidance of the doctor’s diagnosis. Huang Jing belongs to a kind of traditional Chinese medicine, which is clinically used medicinally mainly as the dried rhizome of Dian Huang Jing and Huang Jing, both of which are plants of the lily family. This medicine can be used clinically to replenish qi and nourish yin, strengthen the spleen, moisten the lungs, and benefit the kidneys, targeting not only weakness of the spleen and stomach qi, such as fatigue and lack of appetite; but also weakness of the spleen and stomach yin (insufficient yin in the spleen and stomach), such as night sweating (abnormal sweating after going to sleep, but stopping sweating after waking up), dry mouth, little food, and a red, mossless tongue. In addition, the drug can also be used to treat lumbar and knee soreness (a feeling of soreness and weakness in the waist and knees) and premature whitening of the beard caused by deficiency of kidney essence. However, the dosage of Huang Jing needs to be adjusted according to the condition, and should be between 9 and 15 g a day, and the drug should be used with caution for people with spleen deficiency and dampness obstruction, phlegm-dampness congestion. The specific use of the drug should follow the doctor’s instructions.
