Equisetum arvense
Anti-tumourpreliminary evidence
Horsetail's silica and flavonoids (apigenin, kaempferol) show anti-cancer activity against lung, colon, and breast cancer cells. Silica from horsetail supports connective tissue strength — relevant for cancer patients experiencing bone metastases or surgical recovery. As a diuretic it reduces oedema associated with cancer treatment.
