Although the branches and leaves of Drip Guanyin are poisonous, it will make your mouth numb, but its fruit is edible. A friend said that he had tasted the fruit himself, and the result was exactly the same as yours. As long as it is completely cooked, red and soft, it tastes good. He said that he had read from books that Dazhu (closely related to Dishuiguanyin, belonging to Araceae) was also a poisonous plant. Eating branches and leaves can also numb your mouth, but its fruit can also be eaten. There are many similar examples. For example, tomatoes are delicious, but their branches and leaves have a strange smell that you don't even want to smell. It is normal that the branches and leaves of plants are poisonous and the fruits are edible. Because they need toxic or smelly substances to protect their branches and leaves from herbivores. But they need to make their fruits delicious and nutritious, so that more animals can eat their fruits and spread seeds for them. This is not a contradiction. Finally, it is not recommended to eat.
