Mild Toxicity: Dogwood berries, particularly those of the flowering dogwood (Cornus florida), are mildly toxic to humans. They contain a bitter-tasting substance known as tannin, which can lead to gastrointestinal discomfort if ingested in large quantities.
Avoid Consumption: It is advisable to avoid consuming dogwood berries as a precaution. The mild toxicity and bitter taste serve as natural deterrents to discourage their consumption.

Symbolic Importance: In Christianity, the dogwood tree holds symbolic significance. Legend has it that the dogwood tree once bore large, edible fruits. However, after being used for the crucifixion of Jesus, the tree was cursed, resulting in smaller, inedible fruits. This symbolic narrative does not reflect the actual edibility of the berries.
