Are sweet potatoes classified as herb?

No, sweet potatoes are not classified as herbs.

Here's why:

* Herbs are typically defined as plants with leaves, stems, or flowers used for flavoring, medicinal, or aromatic purposes. Sweet potatoes are root vegetables, meaning the edible part is the root.

* Sweet potatoes are classified as a starchy root vegetable. They belong to the *Convolvulaceae* family, which includes morning glories.

While sweet potatoes can be used in some dishes for their sweet flavor, they are not considered herbs because they are not primarily used for their flavoring or medicinal properties.
