Are yew trees useful to drug manufacturing companies?

Posted by gardendoctors (My Page) on

Hello,
I've been asked by a customer to fell some large yew trees. I remember reading a while back that the leaves can be used to manufacture cancer drugs. Anyone know a company who collects them?

Thanks
James

Paclitaxel (aka taxol) is derived from the bark of the Pacific yew (Taxus brevifolia) only. As this is an ecologically threatened species in the wild and not widely grown commercially, interest was generated in synthesizing the drug. Complete synthesization did not prove economically feasible so a semi-synthetic process using a distillate of foliage from European yews was devised. Sources indicate all of this material is manufactured for Bristol-Myers Squibb (patent holder) by a German company, Phyton Biotech Inc. Whether or not they purchase raw material from Joe Homeowner is anyone's guess.

Hi, iirc the companies that collect the yew are only interested in young shoots that are harvested at the correct time of year, such that they have the highest concentration of the compounds they need. In other words they want hedge trimmings not whole trees.

They buy yew hedge clippings from members of the public, and if you have a large enough hedge they used to (probably still do) offer to cut it for free in exchange for the clippings. Here is a link to one of the Yew harvesting companies:
