Taxol, a widely used chemotherapy drug, is extracted from the bark of the Pacific yew tree (Taxus brevifolia). This drug is particularly effective in treating cancers such as breast and ovarian cancers. It functions by stabilizing microtubules and preventing their depolymerization, which disrupts cell division in cancer cells.
