The Antibacterial Properties of Trapa Natans

Tannins

• Chestnuts contain tannins, the same type of biomolecule found in many wines. Studies on tannins have indicated possible benefits of a stronger heart and increased immune system when ingested regularly. The tannins help suppress artery-clogging plaque and seem to fight off heart disease. As an alternative to using antibiotics on poultry farms, the Poultry Science Association commissioned a study on the effect of chestnuts on animal feed. The study found that the antimicrobial properties and tannins contained in chestnuts proved to be a promising alternative to using antibiotics to prevent disease on poultry farms. Further studies have also shown a reduction in bacteria after the administration of chestnut tannins.

Medicinal Properties

• In traditional Chinese medicine, the water chestnut acts as a remedy to prevent or treat a variety of disorders from dehydration to osteoporosis. Recent studies in Japan used the extract from water chestnuts as part of a compound to test as an anti-carcinogen. The CIDP International Foundation reports that extracts from the water chestnut have shown promise during pharmacological experiments as a treatment for defending and resisting cancer.

Antioxidant and Antimicrobial Uses

• A study published in the Czech Journal of Agricultural Sciences showed a correlation between the antimicrobial properties of chestnut extract and the reduction of free radicals, indicating the presence of antioxidants. The study revealed that the spurs and bark of the chestnut had the highest concentrations of antimicrobial activity. After the administration of the chestnut extract, the bacteria and free radicals under observation showed significant reduction in size and volume.
