Inquiring about all kinds of information shows that "Eichhornia crassipes, although it is a kind of fruit, should not be eaten raw. It needs to be cooked and peeled off before it can be imported, so that you can eat layers of fragrant yellow pulp."

As for whether there are poisoning symptoms after eating raw food, there is no information, but it should not be poisoned. As a kind of fruit, it will not be poisoned by improper eating methods, otherwise it will attract attention early and indicate that it must not be eaten raw.
