Rosemary
Salvia rosmarinus
Carnosol, carnosic acid, and ursolic acid from rosemary show anti-tumour activity against breast, colon, prostate, and lung cancer cells. Carnosol induces apoptosis and inhibits invasion and metastasis. Rosemary also upregulates phase II detoxification enzymes that neutralise carcinogens.
