A really great poison ivy remedy I know of to help with these symptoms is to drink a brew of iced tea using cooling herbs. Get a tablespoon each of burdock, dandelion, cleavers, chickweed and mint and steep for an hour or longer in a quart of boiling water. Double the recipe and drink several cups a day. This will definitely help with the hot feeling that comes along with the rash. Do yourself a favor and eliminate hot spicy foods from your diet until the poison ivy is gone.
