Traditional Uses of Che Fruit in Korean and other Asian cultures

 Cudrania tricuspidata, commonly known as silkworm thorn, has been employed for centuries across East Asia as a multipurpose folk remedy. In Korean traditional medicine, the bark and root have been decocted to alleviate eczema, mumps, pulmonary tuberculosis, contusions, insomnia, and acute arthritis. (1) Leaf preparations are ingested or applied topically to reduce inflammation, harnessing their rich flavonoid and xanthone content to modulate NF-κB signaling and suppress pro-inflammatory cytokines such as IL-6 and IL-8 in skin cells. (7) Water- and ethanol-soluble fractions from the stems and roots have demonstrated antioxidant and cytotoxic activities, inhibiting the growth of macrophages and carcinoma cells, which supports their historic use in treating tumors and immune-related disorders. (43) Moreover, ethanol extracts of leaves have been shown to exert gastroprotective effects by inhibiting H₂-receptor-mediated acid secretion and enhancing gastric mucins, reflecting their application against gastritis and dyspepsia in Korean folk practice. (44)

Practical Applications and Consumption of Che Fruit

Cudrania tricuspidata, commonly known as mandarin melon berry, offers a range of health-promoting uses and can be consumed in various forms:

• Gastroprotective agent: Ethanolic leaf extracts inhibit histamine H₂ receptor–mediated gastric acid secretion and enhance mucin production, helping prevent gastritis and functional dyspepsia when taken as teas or supplements (45)
• Functional food against Helicobacter pylori: Leaf extracts reduce H. pylori–induced inflammation and bacterial load in the stomach, supporting eradication and alleviating ulcers as a dietary adjunct (46)
• Metabolic health support: Whole‐leaf extracts activate the Nrf2/HO-1 antioxidant pathway, improving liver function and reducing fat accumulation in high‐fat diet–induced nonalcoholic fatty liver disease models, suggesting potential incorporation into nutraceutical drinks (47)
• Nutraceutical source of bioactive phytochemicals: Rich in xanthones, flavonoids (e.g., cudraflavone B, kaempferol), polysaccharides, and organic acids, the fruits and leaves can be processed into powders or extracts for anti-inflammatory, antioxidative, antitumor, and anti-obesity applications (1)

Who should avoid consuming Che fruit

While Cudrania tricuspidata offers promising anti‐inflammatory and gastroprotective benefits, certain populations may face heightened risks and should refrain from its use:

Individuals who were pregnant or lactating were explicitly excluded from an 8‐week randomized, placebo‐controlled trial assessing C. tricuspidata extract for functional dyspepsia due to unknown fetal and neonatal safety profiles. (24)

Those with pre‐existing hepatic impairment should avoid the extract, as case reports document severe hepatotoxicity including acute liver failure following just three days of extract intake. (48)

Patients concurrently using H2 receptor antagonists, corticosteroids, NSAIDs, or aspirin were also excluded from clinical studies to prevent potential drug interactions and confounding safety signals. (24)

Finally, individuals with a history of hypersensitivity or allergic reactions to C. tricuspidata compounds risk acute generalized exanthematous pustulosis or urticaria and should not consume the extract. (48)

Possible side effects or interactions with medications

Individuals interested in overall health and wellness should be aware of the following adverse reactions and precautionary measures associated with the use of Cudrania tricuspidata extracts:

1. Hepatotoxicity and renal failure
   Cases of severe liver injury including markedly elevated aminotransferases (AST 364 IU/L, ALT 574 IU/L) and hyperbilirubinemia (total bilirubin 36.3 mg/dL) as well as acute renal failure have been reported after ingestion of C. tricuspidata extract for just three days; one patient progressed to combined hepatic and renal failure and succumbed to complications (pneumonia and multi-organ failure). (48)
2. Acute generalized exanthematous pustulosis (AGEP) and urticarial rash
   A 42-year-old woman developed widespread rash with small pustular vesicles after three months of C. tricuspidata extract intake. Treatment with systemic corticosteroids and antihistamines led to resolution within one week, indicating a potential for severe cutaneous adverse reactions. (49)
3. Limited human safety data
   Beyond isolated case reports, there is a lack of controlled clinical trialsassessing the safety profile of C. tricuspidata in diverse populations, including pregnant or lactating individuals, pediatric or elderly patients. Until such studies are conducted, vulnerable groups should avoid its use or consult healthcare professionals before supplementation.
4. Potential for herb–drug interactions
   tricuspidata contains bioactive flavonoids and xanthones that may influence drug-metabolizing enzymes such as CYP450 isoforms. Patients on prescription medications especially hepatically metabolized drugs should exercise caution and seek medical advice to mitigate the risk of altered drug levels.
5. Dose standardization and product quality
   Commercial preparations vary widely in extract concentration and purity. Without standardized dosing guidelines or third-party testing, consumers may unknowingly ingest supra-therapeutic amounts or contaminants. Always choose products from reputable manufacturers and follow dosing recommendations on the label under professional guidance.

Conclusion

Che fruit (Cudrania tricuspidata) emerges as a versatile, science-backed botanical ally whose rich array of flavonoids, phenolic compounds and xanthones underpins a remarkable spectrum of health benefits. From potent antioxidant and anti-inflammatory activities that soothe cellular stress and support liver and gut wellness to metabolic modulation that aids weight management and insulin sensitivity, Che fruit extracts have demonstrated efficacy in preclinical and emerging clinical studies. Its protective effects extend to neuroprotection, skin barrier reinforcement and even supportive roles during chemotherapy, while traditional uses in East Asian medicine are now validated by modern phytochemical analyses. Although promising, Che fruit’s hepatotoxicity reports and potential drug-interaction risks underscore the need for standardized dosing and further safety trials. Overall, C. tricuspidata offers a multifaceted natural supplement whose therapeutic promise warrants continued research and cautious, evidence-based application.
