This is for topical podophyllum, a cure for warts (a prescription drug, because it's poison):

Early symptoms of too much medicine being absorbed into the body

Abdominal or stomach pain; clumsiness or unsteadiness; confusion; decreased or loss of reflexes; diarrhea (may be severe and continuing); excitement, irritability, or nervousness; hallucinations (seeing, hearing, or feeling things that are not there); muscle weakness; nausea or vomiting; sore throat and fever; unusual bleeding or bruising.

Late symptoms of too much medicine being absorbed into the body

Constipation; convulsions (seizures); difficult or painful urination; difficulty in breathing; dizziness or lightheadedness, especially when getting up from a lying or sitting position; drowsiness; fast heartbeat; numbness, tingling, pain, or weakness in hands or feet (may not occur for about 2 weeks after medicine is used); pain in upper abdomen or stomach (mild, dull, and continuing), bleeding and pus from all bodily orifices followed by excrutiating tetany and death.

(I added that last bit about bleeding and death.)

But like I'm going to risk convulsions, vomiting and the rest for a wart cure?????
