Can patients with gastritis use Cornus officinalis (Shanzhuyu)?

Patients with gastritis who present symptoms caused by liver and kidney deficiency or spleen and stomach cold deficiency may usually take appropriate amounts of Cornus officinalis under the guidance of a physician. However, this herb is not recommended when the patient suffers from excessive stomach heat or weak digestion. If in doubt, it is advisable to seek medical consultation in advance. Detailed explanations are as follows:

When gastritis manifests as symptoms caused by liver and kidney deficiency or cold deficiency of the spleen and stomach, such as dull stomach pain, intolerance to cold, poor appetite, etc., appropriate use of Cornus officinalis may be beneficial. Cornus officinalis functions to nourish the liver and kidneys and to consolidate vital essence, which can help alleviate gastric discomfort caused by physical weakness, particularly suitable for individuals with a cold constitution or long-term physical debility.

If gastritis is accompanied by symptoms of excessive stomach heat or weak digestion, then Cornus officinalis should not be used. This herb has a rich and greasy nature, which may exacerbate internal accumulation of damp-heat, causing symptoms such as dry and bitter mouth, thick greasy tongue coating, or a burning sensation in the stomach. Moreover, if there is abnormal gastric acid secretion or significant inflammation, using Cornus officinalis might further impair gastrointestinal function, worsening discomfort.

During the use of Cornus officinalis, patients with gastritis should maintain a bland diet and avoid eating greasy, spicy, raw, or cold foods, which may interfere with the herb's effectiveness or aggravate stomach discomfort.
