II. Contraindications
1. Not Suitable for Patients with Kidney Disease
Starfruit contains neurotoxins. Patients with kidney disease may have poor kidney function and may be unable to effectively excrete these toxins, leading to toxin accumulation in the body, which may cause poisoning and adverse effects on the central nervous system.
2. Diabetic Patients Should Consume Cautiously

The organic acid content in starfruit may irritate the gastrointestinal tract and worsen symptoms of digestive system diseases such as gastric ulcers.
4. Not Suitable for Individuals with Cold or Fever Symptoms
Although starfruit has heat-clearing and detoxifying effects, individuals with fever or cold symptoms experience significant physical depletion, and excessive consumption may increase gastrointestinal burden, which is not conducive to recovery.
5. Pregnant Women Should Consume Cautiously
Pregnant women should choose fresh and hygienic starfruit to avoid affecting fetal health due to food poisoning.
