Hello! I'm glad to answer your question!
Avena sativa is edible, avena sativa is a healthy woody grain and oil plant unique to our country, and a valuable medicinal and food plant. The fruit itself is a kind of oil fruit, avena sativa in the green fruit stage (when the fruit is white) can be eaten.
If its fruits are white, they can be eaten directly and have a sweet and refreshing flavor. It is recorded in the "Imperial Capital Chronicle" that those who ate it praised it for its sweet flavor and tenderness, and thought of it as a prune. But if the seeds turn black, do not eat, indicating that the seeds are fully mature, can be used to squeeze oil with.
