How do corn silk extracts “kill” cancer cells?
"Study" of Multiple Target Signaling: Using three human breast cancer cell lines (PANC-1, SW1990, and BxPC-3), this study showed that S1 can inhibit growth in a concentration-dependent manner, with an IC50 value of 0.82 mg/ml. Mechanistically, S1 inhibits the EGFR/PI3K/AKT/CREB axis, activates cyclin D1 and Bcl-2, and activates Bax and caspase-3, which inhibits cancer in S phase and induces apoptosis.
Immune potential: Corn silk extract could improve the intestinal and thymic tissues of mice, promote the proliferation of NK cells and CD8+ T cells, and promote the production of IFN-γ and TNF-α.
Antioxidant + Antiangiogenic: Corn silk extract flavonoids and glutathione peroxidase (GSH-Px) work synergistically to destroy reactive oxygen species (ROS), inhibit VEGF secretion, reduce microvessel density by 35% and inhibit "inflammation" after tumor growth.

Can the popular "silk" tea really prevent cancer?
Drinking tea a day is not a test. Consuming 3-6 grams of good polysaccharides daily is good. corn silk extract tea bags contain only 1-2% polysaccharides, which would require 150-300 grams of wheat flour per day and a lot of milk. Excessive consumption can cause electrolyte imbalances.
Side effects and contraindications: Frequent urination leads to potassium and sodium depletion; taking warfarin or furosemide increases the risk of bleeding or blood thinning; high doses over a long period of time are not recommended for pregnant or breastfeeding women, or people with low blood pressure.
Note: Consider corn silk extract tea as "pure, flavored water" and not as a substitute for surgery, chemotherapy, or radiation therapy. Cancer patients who wish to try supplements on a blood level should have their electrolyte levels and blood type checked under the guidance of a doctor.
