- There are several kinds of yew including the English or European yew (Taxus baccata), Pacific yew (Taxus brevifolia) and Japanese yew (Taxus cuspidata). All species are considered poisonous; however, there is some debate about the medicinal value of the fruits (arils). The name 'taxus' may be related to the Greek 'toxon' (bow) and 'toxicon' (the poison with which the arrowheads were dressed).
- Traditionally, the fruit of yew has been used as an antitussive (preventing or relieving cough), menstrual stimulant, abortifacient (induces abortion), diuretic and laxative. It is reported that the Native Americans used yew extracts to treat rheumatism, fever, and arthritis.
- Paclitaxel (Taxol®) was isolated from the bark of the Pacific yew tree (Taxus brevifolia) as early as 1971 and is now approved by the U.S. Food and Drug Administration (FDA). Since 1971, Taxol® has been used as an antitumor drug in clinical trials run by the U.S. National Cancer Institute and has been hailed as one of the most significant advances in cancer chemotherapy in recent history. Since 1990, clinical trials using Taxol® have succeeded in treating advanced ovarian and breast cancers.
