Home remedies gone wrong

Today, Ann LaBelle admits that it was a stupid thing to do. But when she jumped off her boyfriend's motorcycle and burned her inner leg on the tailpipe, she didn't know how to treat the injury. "It burned a hole right through my jeans, about the size of a fifty-cent piece." Her boyfriend's mother suggested she clean the area and put butter on it. For the next several days, LaBelle repeated the process. "It kept getting redder and redder, and it really hurt." Two weeks later, when the burn wasn't healing and she developed a 104 degree fever, LaBelle went to the hospital. There she was given antibiotics to fight the infection. But they didn't help. About a month later, she underwent surgery to close up the wound. Sometimes you can use heat or ice to treat an injury, but when it comes to a really bad burn, you need medical care.

The problem with old wives' tales

LaBelle made an all-too-common mistake—she relied on an old wives' tale. Many of our mothers and grandmothers' remedies are no longer recommended. Even traditional first-aid treatment has evolved from the usual first-aid kit stuff, like bandages, some gauze, painkillers, a tube of antibacterial cream, maybe iodine or hydrogen peroxide. Tried-and-true solutions, right? Well, not so fast.

They may be tried, but they're not all true. "Many people still use their mother's remedies, like putting peroxide on a wound," says Michael VanRooyen, professor of emergency medicine at the Johns Hopkins School of Medicine. "This, and other remedies are very common, but wrong." After years of research, experts are finding that your standard first-aid response may sometimes be the worst thing you can do in an emergency. Here are some age-old treatments that are no longer recommended.

Don't: Using butter to treat a burn

You burn your hand—on the stove, an iron, or a hot plate. According to a popular old wives' tale, you should spread some butter on the burn to ease the pain. But that isn't a good idea, says VanRooyen. "Butter was thought to coat the burn, but it can cause infection and create an environment for bacterial growth." Here are more trusted home remedies that only make you worse.

Do: Run the burn under water

Immediately running the burn under cool water will help remove the heat and put an end to the damaging process. "The water will also clean the area, decrease the risk of infection, and make it feel better," says VanRooyen. Next, wrap the burn with sterile gauze or a nonadhesive bandage, and keep it clean and dry. If blisters form, don't break them—the fluid inside is sterile, and it creates a natural bandage over the burn.

Don't: Take syrup of ipecac to treat poison

When a child swallows anything that's poisonous, parents probably think they are well prepared if ipecac syrup is on hand. Wrong, says the American Academy of Pediatrics and the American Academy of Clinical Toxicology. If you have ipecac in your house, get rid of it. For years, ipecac was thought to be a good way to treat a child who had swallowed a toxic substance, but not anymore.

Made from the root of a Brazilian plant, ipecac irritates the stomach to induce vomiting. But a recent study from the Cincinnati Children's Hospital Medical Center found that ipecac doesn't reduce ER visits or save lives. Maybe that's because it doesn't always remove enough of the toxic substance from the body, says American College of Emergency Physicians spokesperson Charles Pattavina, an assistant professor of emergency medicine at Brown University Medical School. Ipecac can leave 40 to 50 percent of the toxin behind. It can also lead to excessive vomiting, a problem that may cause dehydration and prevent doctors from giving other treatments. Another risk: If the poisonous substance is caustic, like lye, it burns the esophagus when swallowed, and can burn it even more when it comes back up.

Do: Call for help

Immediately call the National Poison Control hotline (800-222-1222), which will be answered by your local poison control center. (Store the number in your phone in the event of an emergency.) The experts will be able to tell you what, if anything, to do. If it's a true emergency, they may send you directly to the ER. There the treatment of choice is often activated charcoal (AC), a very finely ground charcoal powder. When the tasteless powder is swallowed (often it's mixed with soda), it will soak up the ingested substance like a sponge, preventing it from entering the bloodstream. The charcoal then passes through the digestive system and is excreted.

It's important to move quickly since AC is best taken within an hour of ingesting a poison. Some poison control centers recommend having AC on hand (it's available in drugstores), but stress that you should never use it without expert guidance. The poison control center will tell you if it's necessary and how much to use, which depends on the victim's weight. Look for AC in powder form or pre-mixed with water (called a slurry). Avoid the capsules—you'd need to swallow 50 of them to get the benefit, says Henry Spiller, director of the Kentucky Regional Poison Center. Check out these other life-saving lessons from real-life poison control center calls.

Don't: Make a tourniquet for excessive bleeding

Once upon a time, every well-trained Boy Scout in America learned how to stop bleeding with a tourniquet. But new studies show this method causes more harm than good. "Only in the most dire circumstances would you want to put a tourniquet on somebody," says Pattavina. Tourniquets can increase the risk of tissue damage or even the loss of a limb, and since there are other methods that can slow blood flow—and preserve life—without the loss of the limb, tourniquets are out. Read up on these secrets that hospitals don't want to tell you, but every patient should know.

Do: Apply direct pressure to the wound

This is what the Red Cross has always recommended and it's the best solution, says VanRooyen. Simply place a clean cloth on the wound and press firmly; don't remove the cloth, even if it gets saturated. If necessary, add more layers of cloth right on top of the first. Applying direct pressure reduces blood flow to the wound. This should stop the bleeding and promote clotting, but still leave blood circulating to the rest of the limb, says VanRooyen. If that's not enough, you can further slow the blood flow by applying pressure to the main artery of the upper arm or leg, depending on the site of the wound. You can learn about this procedure in a first-aid course or through the American Red Cross.

Don't: Treat a cut or scrape with chemicals

When the skin isn't broken, it's hard to beat iodine for killing bacteria. That's why doctors use it to clean an area before surgery. But when there's a cut, says dermatologist Robert Kirsner, a spokesperson for the American Academy of Dermatology, full-strength iodine, hydrogen peroxide, and rubbing alcohol can be toxic to skin cells, impeding healing. The chemical reaction (and bubbling) that occurs when hydrogen peroxide hits the skin isn't only cleaning the wound—it's killing healthy cells. And that stinging from the rubbing alcohol? This stuff hurts because it's wiping out healthy tissue.

Putting iodine on cuts and wounds kills bacteria, says VanRooyen, but it won't clean the wound. "You want to protect the good tissue, and iodine doesn't do that." Mercurochrome also kills bacteria, but as the name suggests, it contains mercury, which is toxic, and not generally recognized as safe, says the FDA. Today, doctors don't use Mercurochrome. Look out for these signs that your cut or scrape is infected.

Do: Rinse the wound

Remarkably, cleansing a wound has become much simpler: "The most effective way to get rid of debris and bacteria without damaging healthy tissue is flushing the wound out with water," says VanRooyen. Put the wound under a faucet, or spray it with the nozzle on the kitchen sink. Flush it with water to clear it of all debris. If you're worried about the bandage sticking to the wound, consider using an antibacterial ointment that contains bacitracin or neomycin to keep the area lubricated.
