  Taxol and the Yew Tree
Taxol is a new anticancer drug that is isolated from taxine, a complex of alkaloids, a natural toxin that causes poisoning by being rapidly absorbed from the digestive tract and interferes with heart action (Feldman et al, 1987).
Taxol inhibits this by binding to a protein called tubulin in cells resulting in the formation of stable, non-functional microtubule bundles (Crown et al, 2000).
Taxol, when used on its own, produced a response in up to 60% of patients with breast cancer (Reichman et al, 1993) and had some effect against ovarian cancer (ten Bokkel Huinink et al, 1997).
