Poison Ivy, Poison Oak, and Poison Sumac

Betsy Dunphy, 44, enjoys living in a woody area in Herndon, Va. But she could do without the poison ivy. She once missed a week of work when a rash from the vine spread all over her face and chest. In the summer of 2002, she developed a poison ivy rash on her wrist after moving azalea plants, and was careful to keep it from spreading.

Rashes from poison ivy, oak, or sumac are all caused by urushiol, a substance in the sap of the plants. Poison plant rashes can't be spread from person to person, but it's possible to pick up a rash from urushiol that sticks to clothing, tools, balls, and pets.

What you can do: Dunphy says she's been able to avoid an outbreak in the last two years mainly by learning what poison ivy looks like and avoiding it. According to the American Academy of Dermatology, while "leaves of three, beware of me," is the old saying, "leaflets of three, beware of me" is even better because each leaf has three smaller leaflets.

"I also wash my garden tools regularly, especially if there is the slightest chance that they've come into contact with poison ivy," Dunphy says. If you know you will be working around poison ivy, wear long pants, long sleeves, boots, and gloves.

Hikers, emergency workers, and others who have a difficult time avoiding poison ivy may benefit from a product called Ivy Block, made by EnviroDerm Pharmaceuticals Inc., of Louisville, Ky. It's the only FDA-approved product for preventing or reducing the severity of rashes from poison ivy, oak, or sumac. The OTC lotion contains bentoquatam, a substance that forms a clay-like coating on the skin.

If you come into contact with poison ivy, oak, or sumac, wash the skin in cool water as soon as possible to prevent the spread of urushiol. If you get a rash, oatmeal baths and calamine lotion can dry up blisters and bring relief from itching. Treatment may include OTC or prescription corticosteroids and antihistamines.

Poisoning in Children

The parents of a 2-year-old boy called the Nebraska Regional Poison Center in Omaha last summer when he accidentally sprayed cleaning disinfectant into his eye. He developed a burn in the cornea. Another 2-year-old boy spent several days in the hospital and survived after drinking charcoal lighter fluid that had been left by the barbecue pit. In another case, a 3-year-old girl got into a bottle containing insecticide and died several days later.

"We see the calls go up every spring and summer," says Joan McVoy, a nurse at the poison center. Children may accidentally ingest sunscreens, berries, cleaning solvents, insect repellents, pesticides, plants and mushrooms, and hydrocarbons in the form of gasoline, kerosene, and charcoal fluid.

The American Academy of Pediatrics (AAP) no longer recommends that syrup of ipecac be used routinely to induce vomiting in poisoning cases. The main reason that the AAP changed its recommendation in 2003 was that, although it seems to make sense to induce vomiting to empty the stomach contents after a poisoning, research hasn't shown that ipecac-induced vomiting is beneficial in improving the clinical outcome of accidental poisoning cases.

Other concerns are that the continued vomiting caused by ingesting ipecac could prevent children from keeping down the activated charcoal they may be given in the emergency room. Charcoal binds to poison and keeps it out of the bloodstream. "There are also some substances that you don't want coming back up because they do more damage, such as drain cleaner and other corrosives," says Arlene Solbeck, an FDA scientist.

The FDA is considering various positions on the safety and effectiveness of ipecac syrup and whether it should still be made available over-the-counter or switched to prescription status.

What you can do: Dangerous substances, including medication, should be kept out of reach of children. In addition, substances should be kept in their original containers to avoid confusion or mistakes. Children who have ingested poisonous substances may experience difficulty breathing, throat pain, or burns to the lips and mouth.

If you suspect that a child has ingested a poison, call the poison center immediately to relay the type of poison ingested and get advice on what to do. If you dial the nationwide poison help line — [phone] — you'll be connected to your regional poison center. Convulsions, loss of breathing, or loss of consciousness require calling 911 immediately. Take the poison with you to the emergency room, whether it's a part of a plant or the chemical's container.

Skin Reactions

Henna tattoos: The Food and Drug Administration has received complaints from people who have received products marketed as henna temporary tattoos, especially so-called "black henna," at places such as salons and kiosks at beaches and fairs. There have been reports of allergic reactions, skin irritations, infections, and even scarring. "Black henna" may contain the added "coal tar" color, p-phenylenediamine, also known as PPD, which can cause allergic reactions in some people. Henna itself is made from a plant and typically produces a brown, orange-brown, or reddish-brown tint. Other ingredients must be added to produce other colors. Even brown shades of products marketed as henna may contain other ingredients intended to make them darker or make the stain last longer. While the FDA has approved henna for coloring hair, and PPD is used in cosmetics as a hair dye, neither of these color additives is approved for direct application to the skin.

Depilatories: The FDA also has received complaints about skin burns and scarring from some chemical hair removal products. If you use this type of product, always do a patch test in accordance with the directions, don't use it on broken or irritated skin, and keep the product away from eyes. Cosmetics don't go through FDA approval before they are marketed, though the agency can take action to get unsafe products off the market.
