The Benefits and Side Effects of Drinking Rehmannia glutinosa (Sh熟地黄) Water

Rehmannia glutinosa (prepared) steeped in water has various effects including nourishing the blood and yin, enriching essence and marrow, benefiting the liver and kidney, and calming a restless fetus. It can improve symptoms such as pallor due to blood deficiency, irregular menstruation, metrorrhagia, liver and kidney yin deficiency, weakness and soreness in the lower back and knees, dizziness, and blurred vision. Additionally, it can help relieve palpitations, insomnia, and fetal restlessness. Drinking Rehmannia glutinosa-infused water also helps produce body fluids, enhance intelligence, improve brain function, moisten the intestines, and relieve constipation, thus contributing to overall health improvement. However, there are also some side effects associated with drinking Rehmannia glutinosa steeped in water. Rehmannia glutinosa is warm in nature, and prolonged or excessive use may cause heat-related symptoms such as oral ulcers and dry mouth. Improper use may damage the spleen and stomach, causing abdominal pain, diarrhea, and loose stools. As Rehmannia glutinosa is metabolized through the liver and kidneys, long-term usage may increase the burden on these organs, potentially leading to impaired liver and kidney function. When consuming Rehmannia glutinosa water, it is important to control the dosage carefully, avoid excessive intake, and consider individual body constitution and health condition to prevent unnecessary health risks. If adverse symptoms occur, prompt medical attention should be sought.
