Damp-Heat and Kidney-Yin are two concepts, and are generally not recommended for Damp-Heat conditions, but can be used as prescribed by the doctor for Kidney-Yin deficiency conditions. Symptoms of Damp-Heat include cephalic drowsiness (a feeling of heaviness in the head and limbs), body drowsiness, dull complexion, loss of appetite, and abdominal distension. Kidney-Yin deficiency usually results in hot flashes (bursts of heat) night sweats (abnormal sweating after going to sleep, sweating stops after waking up), heartburn and insomnia, dizziness and tinnitus, lumbar and knee soreness (a feeling of soreness and weakness in the lumbar and knee areas), decreased menstrual flow or menstrual pre-menstruation, and so on. The Chinese herb Huang Jing is a yin tonic with the effects of tonifying qi and nourishing yin, strengthening the spleen, moistening the lungs and benefiting the kidneys. It is used for spleen and stomach qi deficiency, tiredness and fatigue, stomach yin deficiency (insufficient yin fluid in the stomach), dry mouth and little food, lung deficiency and dry cough, coughing and hemoptysis, lack of essence and blood, soreness and weakness of the waist and knees, premature whitening of the beard and hair, and internal heat and thirst (internal fever accompanied by excessive eating, drinking and urinating). However, it is easy to help dampness, so it is contraindicated for people with spleen deficiency, dampness, cough and phlegm, as well as cold and loose stools (thin and unshaped feces). Adverse effects are not known. Whether or not it can be taken depends on your own situation, it is recommended that you consult your physician or pharmacist and take it under the guidance of your physician or pharmacist.
