The fleshy aril that surrounds each seed in the yew is a highly modified seed cone scale.. In European yew plants (Taxus baccata), the aril starts out as a small, green band at the base of the seed, then turns brown to red as it enlarges and surrounds the seed, eventually becoming fleshy and scarlet in color at maturity.
Maturation of the arils is spread over 2 to 3 months, increasing the chances of successful seed dispersal. [citation needed] The seeds themselves are poisonous and bitter, but are opened and eaten by some bird species, including hawfinches, [14] greenfinches, and great tits. [15] The aril is not poisonous; it is gelatinous and very sweet tasting.
All parts of the tree except the arils contain the alkaloid. The arils are edible and sweet, but the seed is dangerously poisonous; unlike birds, the human stomach can break down the seed coat and release the toxins into the body. This can have fatal results if yew 'berries' are eaten without removing the seeds first.

Pyrrolizidine alkaloidosis poisoning in the United States has remained moderately rare among humans. The most common reports are the outcome of the misuse of medicinal home remedies, or the alkaloids are present in food and drink substances such as milk and honey when the animal carriers were exposed to the toxins.
