Is it okay to consume Lycium barbarum (goji berries) and Cornus officinalis (Chinese cornel) if one has a cold stomach?

　　In traditional Chinese medicine, cold stomach generally refers to deficiency-cold of the spleen and stomach. Patients with deficiency-cold of the spleen and stomach can usually consume Lycium barbarum (Goji berries) and Cornus officinalis (Asiatic cornelian cherry), but should pay attention to moderate intake.

　　Deficiency-cold of the spleen and stomach typically manifests as symptoms such as sensitivity to cold in the stomach area, cold hands and feet, and poor appetite. In traditional Chinese medicine, Lycium barbarum and Cornus officinalis are considered warming and nourishing substances. Lycium barbarum can nourish the liver and kidneys and improve vision and blood circulation, while Cornus officinalis warms and nourishes the liver and kidneys, and has the effect of consolidating essence and reducing urination. For individuals with deficiency-cold of the spleen and stomach who do not exhibit significant symptoms of damp-heat, moderate consumption of Lycium barbarum and Cornus officinalis may help warm the middle jiao, dispel cold, promote digestion and absorption, and alleviate gastric discomfort.

　　When used together, Lycium barbarum and Cornus officinalis can provide multiple benefits, such as strengthening kidney function, nourishing liver blood, improving vision, and enhancing complexion. Patients with deficiency-cold of the spleen and stomach can consume moderate amounts of Cornus officinalis, but should be mindful of the dosage. Cornus officinalis has a sour and astringent taste and slightly warm nature. Due to its astringent and consolidating properties, excessive consumption may increase the burden on the gastrointestinal system, leading to discomfort symptoms such as abdominal pain and diarrhea. During consumption, patients should closely monitor their physical reactions, and if symptoms like abdominal pain or diarrhea occur, they should seek medical attention promptly.

　　In daily life, maintaining a balanced diet and avoiding excessive intake of cold or greasy foods can help improve stomach health.
