What are the symptoms of Poisoning?
The first symptom of poisoning is a severe itching of the skin. Later, a red inflammation and a blistering of the skin occurs. In severe cases, oozing sores develop. The rash spreads by the poisonous sap (urushiol), not as the result of contamination from sores. The blood vessels develop gaps that leak fluid through the skin, causing blisters and oozing. When you cool the skin, the vessels constrict and don’t leak as much according to Robert Rietschel, M.D. Chairman of Dermatolgy at New Orleans’ Ochsner Clinic.
