<<Disclaimer: Verify this information before applying it to your situation.>> Dr. Holland is correct, Petrolatum is not listed as a neurotoxin. My apologies for the incorrect information. The Vaseline container does say: "Warning: For external use only." Online pharmacies note that in cases of accidental ingestion of petroleum jelly, one should call a physician or poison control center. The only effect of ingestion that I could find was that it causes a mild laxative effect. I would like to hear of anyone experiencing a similar absence of numbness after giving up Chapstick/vaseline products. - Mary in MI *Support summarization of posts, reply to the SENDER not the Celiac List*
