I posted on another site and one of our great service men posted on my thread that the government give them Zanfel when they get poison ivy, oak, or sumac. I found it on ebay and am now armed with 2 tubes of it. No poison ivy so far this year but have used it on itching when I didn't know if it was poison ivy. It is 35 dollars a 1 oz tube at Wal-mart but I bout it for 25 dollars for 2 1oz tubes on Ebay.
I carry scars from last year on my upper arm and I was miserable when I had it. NOTHING I bought or dr gave me worked
Look up also. When I got it I was picking pecans and did not see it hanging down over my head. I use surgical gloves from wal-mart when I see one growing. I pull it up or dig it loose first then I pick it up with the glove on my hand and just peel the glove off carefully over my outside trash can.
