Word to the Wise about Yew

 Yew is poisonous because it contains taxine alkaloids, especially taxine B, which block calcium and sodium channels in the heart. This disrupts electrical conduction and muscle contraction, leading to life‑threatening arrhythmias and cardiac arrest. All parts of the plant except the red aril are toxic, and the seeds inside the aril are especially dangerous.

Word to the Wise About Buttercups
