Role of Polyphenols in Reducing Inflammation
Polyphenols, such as rosmarinic acid, luteolin, and apigenin, found in shiso leaves, effectively inhibit the production of inflammatory mediators like cytokines and prostaglandins. By reducing the activity of pro-inflammatory enzymes, polyphenols mitigate the inflammatory cascade, alleviating symptoms associated with inflammation.
Cardiovascular Health
Shiso leaves contain an array of compounds that contribute to cardiovascular health. These compounds include antioxidants, polyphenols, and flavonoids, which have been shown to reduce inflammation, improve blood flow, and protect against heart disease.
Blood Pressure
Studies have shown that consuming shiso leaves can help lower blood pressure. The polyphenols in shiso leaves act as vasodilators, which means they relax the blood vessels and reduce resistance to blood flow. This, in turn, lowers blood pressure.
Cholesterol Levels, Health benefits of shiso leaves
Shiso leaves have also been shown to help lower cholesterol levels. The fiber in shiso leaves binds to cholesterol in the digestive tract and prevents it from being absorbed into the bloodstream. Additionally, the polyphenols in shiso leaves help to reduce the production of cholesterol in the liver.
Blood Clotting
Shiso leaves contain compounds that help to prevent blood clots. These compounds include flavonoids and quercetin. Flavonoids help to strengthen the blood vessels and reduce the risk of bleeding. Quercetin helps to inhibit the formation of blood clots.
Antibacterial and Antimicrobial Activity
Shiso leaves possess remarkable antibacterial and antimicrobial properties, making them a potential natural remedy for various infections. These properties are attributed to the presence of essential oils, polyphenols, and flavonoids in the leaves.
Applications in Food Preservation and Infection Control
The antibacterial and antimicrobial properties of shiso extracts have been explored for potential applications in food preservation and infection control. Studies have shown that shiso extracts can inhibit the growth of foodborne pathogens such as Escherichia coli, Salmonella, and Staphylococcus aureus. This suggests that shiso extracts could be used as natural preservatives in food products to extend shelf life and reduce the risk of foodborne illnesses.
Additionally, research has demonstrated the potential of shiso extracts in combating infections. Studies have found that shiso extracts exhibit antiviral activity against influenza viruses, herpes simplex virus, and respiratory syncytial virus. Furthermore, shiso extracts have shown promising results in inhibiting the growth of antibiotic-resistant bacteria, such as methicillin-resistant Staphylococcus aureus(MRSA).
Antioxidant Capacity
Shiso leaves are recognized for their remarkable antioxidant capacity, effectively counteracting the damaging effects of free radicals in the body. Free radicals are unstable molecules that can cause oxidative stress, leading to cell damage and chronic diseases. The antioxidant compounds present in shiso leaves, such as polyphenols and flavonoids, neutralize these free radicals, preventing their harmful effects.
Comparative Analysis
Compared to other leafy greens, shiso leaves exhibit an impressive antioxidant capacity. Studies have shown that shiso leaves contain higher levels of antioxidants than spinach, kale, and lettuce. This enhanced antioxidant activity makes shiso leaves a valuable addition to a balanced diet, contributing to overall health and well-being.
