Is the fruit on the colorful tree poisonous?

Colorful fruits are not poisonous. Although there is a record of raw food, it tastes sour and tastes bad. So the ancients used their wisdom to make wine with this fruit. What they didn't expect was that it worked wonders. The wine brewed with this fruit is sweet and sour and very mellow. So this wine-making method has been passed down to this day.
