Poison Ivy, Oak, And Sumac Have Different Foliage, But Produce The Same Irritating Chemical And Identical Rashes. In certain areas there is enough sunlight every week of the year to keep this chemical in these plants every day of the year - even when there are no leaves on them and a foot of snow on the ground. It is not necessary to have direct contact with the plants to get the oil-like substance on you. The oil-like substance can be transferred from tools, animals or clothing to your skin. It is not blown through the air; rarely, droplet vaporization may occur when the plants are burned.
The Water From Blisters Does Not Spread Poison Ivy. This Water Is Just Normal Tissue Fluid Brought To The Skin Surface By The Allergic Response In Sensitive People.
About 85% Of The Population Is Allergic To The Oil, Common To All Three Of These Plants. Everyone will become sensitive to this material if exposed to it long enough
We Are Not Aware Of Any Satisfactory Desensitization Shots Or Pills To Prevent Susceptible Persons From Getting Poison Ivy Rash. Some Of The Older Shots Or Pills Could Be Quite Dangerous.
The More Allergic You Are, The More Oil You Get On Yourself, And The Longer It Remains On Your Skin, The Worse Your Reaction Will Be.
The Best Policy Is Learn To Identify The Plants And Avoid Them, Even Without Leaves. When Contact With The Plant Or Oil Is Unavoidable, Or When Touching Something That May Have Had Oil On It, Wash Promptly With A Strong Bar Soap Like Felsnaptha. It is possible to wash soon enough not to develop a rash. When the above measures are not enough, remember: There are extremely effective medicines to keep you comfortable and heal the rash promptly. The earlier they are given, the more they help. Usually all you get by delaying treatment is more rash.
