Treatment of yew ingestion is generally only administered if there is evidence that the animal has ingested a part of the plant. The animal can be treated with charcoal or mineral oil. If the animal has cardiac arrhythmias then they should be treated accordingly. One other possible way to treat animals for yew ingestion, cattle in particular, is to open up the stomach and remove the contents. This procedure, called a rumenotamy, may lessen the amount of toxin that will be absorbed into the body.
Yew poisoning is a great example of the dangers of disposing garden clippings to animals.
The toxic amounts of a yew are very small and can prove to be lethal in a short period of time. Since this plant has no deturants to keep animals from ingesting it, we have to be careful where we place yew plants. With such a small quantity to be lethal and the fact that there are no real treatments, the yew is definitely not a plant to take lightly. Appling, Jeanne Willson. Bartik, M. and A. Piskac.
