It is recorded in both the *Shennong Bencao Jing* and *Bencao Zai Xin*, referred to as a "gastrointestinal medicine," and is a commonly used drug for treating stomach pain and upper abdominal distension. Modern medical experiments have confirmed that Dendrobium officinale has a good inhibitory effect on Helicobacter pylori, a common pathogen in spleen and stomach diseases, and is helpful in treating Helicobacter pylori-positive conditions such as atrophic gastritis, superficial gastritis, and duodenal ulcers. Simultaneously, oral administration of Dendrobium officinale decoction can promote gastric juice secretion, enhance gastric emptying, and aid digestion.
