What are the main indications for Radix Scrophulariae, Rehmannia glutinosa, and Ophiopogon japonicus?

Radix Scrophulariae, Rehmannia and Ophiopogon is a traditional Chinese medicine formula composed of Radix Scrophulariae (Xuan Shen), raw Rehmannia (Sheng Di), and Ophiopogon (Mai Dong). It belongs to the category of yin-nourishing herbs in traditional Chinese medicine and functions to nourish yin fluids and clear deficient fire. It is suitable for symptoms caused by yin deficiency with hyperactive fire, such as dry mouth, sore throat, and throat swelling. It also has a certain moistening effect on the lungs and can be used to treat coughing, minimal sputum, and difficulty expectorating caused by lung dryness. This formula acts on the heart meridian, nourishes yin, and promotes the production of body fluids, thereby helping to alleviate symptoms due to stomach yin deficiency and depletion of fluids, such as thirst, dry cough, and general debility. The Radix Scrophulariae, Rehmannia, and Ophiopogon decoction also helps moisten dryness, relieve restlessness, promote fluid production, and quench thirst, effectively improving constipation symptoms such as dry and hard stools caused by insufficient body fluids.

Although the combination of Radix Scrophulariae, Rehmannia, and Ophiopogon offers various therapeutic benefits, it is not suitable for everyone. Dosage and method of use should be selected according to individual constitution and medical condition, and it should be used under the guidance of a physician.
