The Danger: Severe poison ivy can make a person seriously ill, often requiring hospitalization.

Symptoms: The first exposure need not necessarily cause a reaction, but the second or subsequent exposure may produce a red, swelling, itching rash, which soon develops into clusters and linear streaks of small blisters or a number of large ones, which eventually break open, leaving crusts. Serious cases can be grim; the rash and blisters can spread all over the body, far beyond the evident actual sites of contact. There is no immunity-one attack makes the victim all the more susceptible to the next.

Treatment: If contact is suspected, area must be washed within fifteen minutes; later washing is useless as the toxin has fixed itself to the skin. All affected clothing should be laundered or dry-cleaned. The infected area should be treated with a compress of Burow’s solution (dilution: 1 to 15). Apply freely, as much as is necessary. Inoculation against poison ivy has had only haphazard success; severe cases should be treated by a physician.

Prevention: Everyone should be familiar with these prolific, poisonous plants, which are ubiquitous in the United States. A five minute study of these weeds will be enough to forewarn a person for a lifetime.

Contact dermatitis is also caused by poison ivy, poison sumac, and poison oak, all of which have the same toxic oil, urushiol. About 75 percent of the population is potentially allergic to poison ivy, which is found as a climbing plant or low shrub.

Poison ivy flourishes in the eastern United States, while poison oak is found in the west; they are easily identified by their leaves, which grow in threes, and their whitish berries. All three plants are toxic the year round.

The oil is so volatile that contact with clothing, farm tools, or pets that have brushed against these plants or even smoke from burning poison ivy leaves can initiate the inflammation. Poison ivy is not contagious; it cannot be transmitted by the fluid in the blisters.
