I'm sensitive, not allergic, to poison ivy.Your statement sounds good as that is how the sodium bicarbonate affects poison ivy.
I'm very allergic to poison ivy and would have it on both legs arms and face.
Boric acid works good on the face.
When I either realize that I have touched it, or I start to itch on my hands, I take an antihistamine. It stops the itch and reduces the blisters to a point they barely show.
Oops, tax:
The skies opened up while I was in the hoop coop yesterday evening, and so I waited until the rain tapered off. The Dominiques decided to preen and get up on the roost before the Sussex (who usually hog it to themselves)!
