While the leaves and stems of anise plants are technically edible, they are not typically consumed as a food source.

Here's why:

* Flavor: The leaves and stems have a much milder anise flavor compared to the seeds, which are the primary part used for flavoring.

* Texture: The leaves and stems can be tough and fibrous, making them unpleasant to eat raw.

* Limited culinary uses: While you could technically use them in small quantities for flavoring, there are generally better options available, like the seeds.

Instead of eating the leaves and stems directly, it's recommended to use the seeds, which are the most flavorful and easily accessible part of the plant.

If you're curious about trying the leaves, you can use them in small quantities in herbal teas or as a garnish. However, keep in mind that their flavor will be significantly less intense than the seeds.
