Contraindications
I. Population Contraindications Spleen‑stomach deficiency cold: Wampee fruit is warm in nature but sour in taste. Excessive consumption may irritate the gastrointestinal tract. Those with spleen‑stomach deficiency cold (prone to diarrhea, stomach pain, intolerance to cold) should not eat too much. Pregnancy: Wampee fruit has qi‑moving and blood‑activating effects. Pregnant women should avoid large amounts to prevent disturbing the fetus. A small amount may be consumed after consulting a physician. Diabetes: Wampee fruit contains relatively high levels of sugar (rich in soluble sugars). Intake should be controlled; do not overeat. Hyperacidity, gastric ulcer: Wampee fruit contains organic acids that may stimulate gastric acid secretion and aggravate stomach discomfort. II. Precautions for Use Do not overeat: Each serving should not exceed 100–150 g. Overconsumption may cause dry mouth,上火 (heat‑related symptoms), bloating, and diarrhea. Avoid on an empty stomach: Organic acids can irritate the gastric mucosa, leading to stomach pain and acid reflux. Avoid eating together with cold‑nature foods: Otherwise, it may damage the spleen and stomach. Avoid unripe fruit: Unripe wampee fruit is sour and astringent, with higher organic acid content and stronger irritation. III. Adverse Reactions Excessive consumption may cause dry mouth, sore throat, oral ulcers, and other 上火 (heat‑related) symptoms. Overeating may lead to stomach pain, acid reflux, and diarrhea.
