The Hidden Danger in Your Home? Unmasking the Toxicity of the Smooth sumac Plant.

In contrast to numerous other sumac relatives (such as poison oak, poison ivy, and various other sumac types), smooth sumac is generally not harmful to most individuals. The berries and foliage of this species might trigger allergic responses—upon contact or consumption—in those with cashew sensitivities (cashews belong to the sumac family). These reactions will vary based on the severity of an individual's allergies, with symptoms spanning from skin irritation to a swollen throat or breathing difficulties. For all others, smooth sumac poses no threat.
