Full Answer

To treat an allergic reaction, flush the face, eyes and hands with water if they have come in contact with rhubarb leaves. Some of the symptoms of a rhubarb leaf poisoning include throat and mouth burning, diarrhea, difficulty breathing, stomach pain and eye pain, red-tinged urine, vomiting, seizures, nausea and weakness.

Symptoms that go on one to three days may need hospitalization. Serious cases can lead to kidney failure, and, rarely, deaths are reported.
