Scientists in Britain believe they have found a way to use an extract from the autumn crocus to kill cancer cells.
In one laboratory study with mice, half the animals were in effect cured after a single treatment.
Professor Lawrence Patterson of the Institute of Cancer Therapeutics at Bradford University says the active molecule in the new drug is distinctive in that it does not harm healthy tissue.
He says it works by destroying the blood vessels that nourish the tumour without toxicity to the patient.
