Dendrobium is often combined with Radix et Rhizoma Dioscoreae, Radix et Rhizoma Ginseng and other medicines, but there is no such thing as what is the best with what. Dendrobium with Radix Rehmanniae Praeparata is suitable for dry mouth and throat, low fever and thirst caused by heat disease, dark tongue and black moss. Dendrobium with Radix et Rhizoma Ginseng is suitable for the lack of stomach yin (lack of yin fluid in the stomach) caused by the lack of food and drink, noisy in the stomach (the stomach has a feeling similar to hunger, emptiness with burning), stomach and epigastric hidden pain or burning pain, dry vomiting or eructation (hiccups), the tongue is red and less moss, etc.. Dendrobium is forbidden to be taken by those who have not injured the yin in the early stage of warm-heat disease, those who have not transformed dryness in wet-warm disease (warm disease caused by feeling dampness and heat), and those who have deficiency cold in the spleen and stomach (spleen and stomach are weak and cold). If you need to use the medicine, you should go through the doctor’s diagnosis and follow the doctor’s instructions to standardize the treatment.
