Many of us fall back on folk medicine remedies for ailments, whether they’re proven to be effective or not. We asked editors at some of our Reader’s Digest editions around the world to share those that work for them – and then we checked out which ones are backed up by research. Here are our favourites.

Vinegar fights infection (France)

French folklore has it that during the 17th-century plague, a gang of four thieves would rob corpses, yet never catch the plague themselves. Supposedly, anointing their bodies with a concoction of vinegar and herbs protected them. The so-called vinaigre des quatre voleurs (four thieves’ vinegar) is used today in the belief it fights infection.

Many of the ingredients steeped in it – garlic, rosemary, sage, lavender, thyme, juniper berry, black pepper and more – are proven to have antibacterial properties. “I know people who consume this regularly as an antibacterial,” says Stéphane Calmeyn, Paris-based editor of Reader’s DigeSt He adds that a friend of his with Type 2 diabetes credits it with helping regulate his blood sugar. Though more research is needed, there is evidence that vinegar, particularly apple cider vinegar, can affect blood sugar levels: it delays the rate at which the stomach empties and starch is digested, which reduces the blood-sugar spike after a meal. But check with your doctor before adding it to your diet, particularly if you are taking blood-sugar-lowering medications.

Apple cider vinegar may also prevent overeating. A small Swedish study found that those who consumed vinegar with a meal reported feeling more satiated than those who didn’t consume vinegar. That could prevent unhealthy snacking later in the evening. It’s best not to drink vinegar undiluted, as its acidity could damage tooth enamel. Instead, add one or two teaspoons to water or tea.

Here are 12 myths about apple cider vinegar you should stop believing now.

Papaya aids digestive health (Malaysia)

When her husband got food poisoning while travelling in Malaysia in 2017, editor Bonnie Munday heeded a recommendation for a local remedy. “We didn’t have any medicine for tummy troubles, but our hotel manager advised eating ripe papaya,” says Bonnie, who is on Reader’s Digest’s International Edition team and is based in Toronto. She was sceptical but bought some of the fruit from a beach vendor. “An hour or two after my husband ate it, he felt so much better.”

A study from Obafemi Awolowo University in Nigeria published in the Journal of Medicinal Food found that papaya, an orange-fleshed fruit that grows in the tropics, fights intestinal parasites. When researchers gave a papaya seed preparation to children who tested positive for intestinal parasites, it was shown to be anti-helminthic (capable of eliminating parasitic worms) and anti-amoebic (capable of destroying or suppressing amoebas); it treated their parasites without harmful side effects.

And results of a double-blind placebo-controlled trial that were published in the journal Neuroendocrinology Letters in 2013 showed that volunteers with digestive complaints like bloating and constipation had significant improvements after ingesting a papaya pulp supplement called Caricol. Papaya is also rich in vitamin C, and high in water and fibre content, which regulates bowel activity. “Ever since that time in Malaysia,” says Bonnie, “if we see papaya at the store, we buy it, just for overall digestive health.”

Calendula calms inflammation (Germany)

“Many people in Germany consider calendula a miracle cure, and have their own recipe for a balm,” says Annemarie Schäfer, who works on the RD team in Stuttgart. Her cousin Marlen, a teacher, recalls that when her mother grew calendula – also called marigolds – in her garden, she’d mix their orange and yellow heads with warm pork fat (you can also use petroleum jelly, beeswax or olive oil). After a day of steeping, the mixture was strained and jarred, to be used on rough hands, insect bites, acne and other skin irritations.

High levels of antioxidants in the dried petals reduce the damage caused by free radicals. Laboratory and animal research has shown the flowers contain anti-inflammatory and antimicrobial components that prevent infection and heal wounds by helping form new blood vessels and tissue. In patients with venous leg ulcers treated with either calendula ointment or saline solution dressings, calendula helped ulcers heal much faster.

Licorice relieves sore throat (Netherlands)

Licorice-based candy, called dropjes, are as Dutch as wooden shoes – but while few farmers still wear wooden shoes, everybody eats dropjes. “It’s a sort of national pride,” says editor Paul Robert in Amsterdam. “And you can get them everywhere – supermarkets, newsstands, pharmacies. They come in all shades of brown and black with flavours ranging from very sweet to very salty.”

Besides being somewhat of an addiction for the Dutch, it’s widely known in northern European countries that licorice also serves a medicinal purpose: sore-throat relief. Indeed, a 2013 randomised, double-blind study of 236 people by the Medical University of Vienna found that patients who gargled a licorice solution before going into surgery requiring throat intubation had a lower risk of sore throat after the surgery. The extract of the licorice root, Glycyrrhizin, tastes sweeter than sugar, despite having a zero glycaemic index. But it’s not safe to consume more than 100 milligrams per day, as it can dangerously reduce blood potassium levels. (A cup of licorice tea contains roughly 30 milligrams, according to The British Medical Journal.)

“When I was a child,” says Paul, “the best thing about having a cold was that I’d get lots of dropjes. Sucking on them soothed my throat back then, and still does now.” Dropjes are an acquired taste, especially the salty ones. “Once,” he recalls with a laugh, “I gave them to an American friend, who told me they tasted just as terrible as the raw herring and smoked eel I’d given her earlier!”

Here are 12 more natural gargle remedies that could help ease the pain of a sore throat. 

St John’s wort soothes skin (Slovenia)

“We use a balm containing St John’s wort to promote wound healing and soothe skin,” says editor Maja Lihtenvalner in Ljubljana, Slovenia. St John’s wort is a plant with yellow flowers that’s native to Europe, northern Africa and southwestern Asia. She describes how her friend Neven, a consultant and olive oil producer in his 50s, remembers his grandmother always having the remedy in her kitchen. “Neven would spend summer vacations at her house on the Adriatic Sea, and often got sunburned. His granny would apply a mixture of St John’s wort and olive oil to his painful skin.” She also used it on bruises and insect bites. “He says it was always a relief.”

Animals studies out of Turkey in the past few years have shown that St John’s wort promotes wound healing and also relieves burns; rats treated topically with St John’s wort four times a day experienced more rapid healing than those in the other groups. And a 2010 Iranian randomised, double-blind clinical trial of 144 women published in the Journal of Alternative and Complementary Medicine showed that women who had undergone caesarean sections and applied a St John’s wort ointment three times a day for 16 days had improved wound healing and less pain and scarring than those in the placebo and control groups. Ingesting St John’s wort can also treat mild to moderate depression, and menopause symptoms such as hot flashes. But speak to your doctor before taking it, because it can cause serious side effects and drug interactions.

Arnica reduces bruising (Mexico)

Arnica is popular in Mexico, says RD editor Luis Eduardo Pineda in Mexico City. “I played basketball when I was a kid, and sometimes my fingers would get painfully bruised. My mother would rub them with arnica balm, and in a few days the bruising would be gone.” These days, Luis uses it for sore muscles. “I keep arnica balm in my first-aid kit.” Anti-inflammatory arnica, from the same family as asters and daisies, is said to reduce swelling and bruising. A 2013 review of 174 people with hand arthritis found that arnica gel reduced pain and improved function in the hand as effectively as an ibuprofen gel. As arnica can be poisonous, it should not be taken by mouth.

Luis has another go-to: aloe vera, or sábila. A review of four studies from Asia, published in the journal Burns, concluded that aloe mucilage (the gel inside its leaves) and some aloe products can accelerate healing of minor burns several days faster than conventional medication. “Not long ago, I accidentally grabbed the handle of a hot pan,” recalls Luis. “Luckily I keep sábila in a flowerpot on my patio, so I got relief quickly.”

Here are more surprising home remedies for burns.

Macela soothes cough (Brazil)

“When we were kids, if we had a cough my grandmother would whip one egg yolk with sugar and, when it had whitened, combine the mixture with a cup of macela [also spelled ‘marcela’] tea,” says Tanara Vieira, a designer for Reader’s Digest from Rio Grande do Sul. “It tasted so good that my sister, my cousins and I used to pretend we were coughing so she would give it to us.” Across Brazil, plants have long been used medicinally. A review of several studies published in 2014 in the Brazilian Journal of Pharmacognosy sought to show whether a variety of plants of the southern Rio Grande region offers the health benefits they are purported to. The review showed that indeed, in several pre-clinical studies, there’s evidence Tanara’s grandmother was right: macela (Achyrocline satureoides), which is a plant in the daisy family, appears to be antispasmodic, helping relieve a cough. It’s also muscle-relaxing, anti-inflammatory and analgesic.

Olive oil softens earwax (Spain)

We need earwax because it keeps the skin inside the ear moisturised and helps prevent dirt and bacteria from reaching the inner ear. But a build-up of too much wax can form a plug, contributing to hearing loss, ringing in the ears, or dizziness. (Find out more medical reasons you’re feeling dizzy.) Plugs, called cerumenosis, can happen if you use cotton swabs, which push wax in, or if you’re naturally prone to the build-up. It can happen especially in elderly people or those who wear hearing aids. People in many parts of the world find that a little warm oil, such as almond or olive, can soften the wax, unplugging the ear canal.

Natalia Alonso, Madrid-based Reader’s Digest editor, says her sister-in-law, Carmen, goes to her doctor to get built-up earwax removed, but she sometimes treats it herself. “On a recent beach holiday in Galicia, she noticed her hearing had diminished, and knew what the problem was,” says Natalia. “So she dipped a cotton swab in warm olive oil and let a little drip into her ear, and soon the clog disappeared.” A University of Southampton review of 26 clinical trials found that earwax softeners are effective, and that side effects are rare. Nevertheless, it’s recommended you check with your doctor before attempting self-treatment of ear issues.
