Yes, you can eat sour gum, referring to the fruit of the Nyssa sylvatica tree (also known as the black tupelo). However, be aware that the fruit is known for its sour taste.
The term "sour gum" is a common name for the Black Tupelo tree, and it's named that because the small fruit it produces has a distinctively sour flavor. While edible, its tartness isn't everyone's favorite, and it is more commonly used for wildlife food.
It's important to clarify that "sour gum" in this context refers to a specific type of fruit and not chewing gum.
