Many home remedies exist that may help treat a variety of things, such as colds, inflammation, and pain. These are not always supported by research. But, scientists suggest that some may indeed work.

Chances are you’ve used a home remedy at some point: herbal teas for a cold, essential oils to dull a headache, plant-based supplements for a better night’s sleep. Maybe it was your grandma or you read about it online. The point is you tried it — and perhaps now you’re thinking, “Should I try it again?”

It’s not clear exactly what makes a home remedy do the trick. Is it an actual physiological change in the body or more of a placebo effect? Thankfully, in recent decades, scientists have been asking the same questions in a lab, and are finding that some of our plant-based remedies aren’t just old wives’ tales.

And so, for the skeptic who needs more than a placebo to feel well, we got your back. Here are the home remedies backed by science:

Who hasn’t heard of turmeric by now? Turmeric has been used, primarily in South Asia as a part of Ayurvedic medicine, for almost 4,000 years. When it comes to proven medicinal purposes, the golden spice may be best for treating pain — specifically pain associated with inflammation.

Several studies have found that curcumin is responsible for turmeric’s “wow” factor. In one study, people with arthritis pain noted that their pain levels were more reduced after taking 500 milligrams (mg) of curcumin than 50 mg of diclofenac sodium, an anti-inflammatory drug.

Other studies back up this pain relief claim as well, noting that turmeric extract was as effective as ibuprofen for treating pain in patients with knee osteoarthritis.

Don’t go grinding turmeric — which stains heavily! — for immediate relief though. The amount of curcumin in turmeric is at most 3 percent, meaning you’re better off taking curcumin supplements for relief.

That’s not to say a soothing turmeric latte won’t help. It’s suggested that 2 to 5 grams (g) of the spice may still provide some benefits. Just be sure you add black pepper to boost the absorption.

Drink a cup per day

Turmeric is about the long game. Consuming 1/2 to 1 1/2 tsp. of turmeric per day should start providing noticeable benefits after four to eight weeks.

This active component of chili peppers has a long history of use in folk medicine and has slowly become more accepted outside of homeopathy. Now, capsaicin is a popular topical ingredient for managing pain. It works by causing an area of the skin to get hot, before eventually turning numb.

Today, you can get a prescription capsaicin patch called Qutenza, which relies on very high level of capsaicin — 8 percent — to work.

So, when it comes to sore muscles or generalized body pain that won’t leave you alone, and you have some hot peppers or cayenne pepper on hand? Make some capsaicin cream.

DIY capsaicin coconut oil cream

  1. Mix 3 tbsp. of cayenne powder with 1 cup of coconut.
  2. Heat the oil on a low simmer until it melts.
  3. Stir the mixture thoroughly for 5 minutes.
  4. Remove from heat and pour into a bowl. Let it firm up.
  5. Massage onto skin when cooled.

For an extra fancy feel, whip your coconut oil with a hand mixer so that it becomes light and fluffy.

It’s important to test your reaction to the compound before using too extensively. You may also use jalapeño peppers, but the amount of heat may vary depending on the pepper. Never use this cream around the face or eyes, and be sure to wear gloves during application.

It’s almost law to try ginger when you have a cold, sore throat, or are experiencing morning sickness and nausea. Making a cup is pretty standard: Grate it in your tea for a stronger effect. But the other benefit of ginger that goes less noticed is its effectiveness as an anti-inflammatory.

The next time you feel a little queasy and have a headache, try ginger. Ginger works differently than other pain relievers that target inflammation. It blocks the formation of certain types of inflammatory compounds and breaks down existing inflammation through an antioxidant that interacts with acidity in the fluid between joints. Its anti-inflammatory effects come without the risks of nonsteroidal anti-inflammatory drugs (NSAIDs).

Ginger tea recipe

  1. Grate half an inch of raw ginger.
  2. Boil 2 cups of water and pour over ginger.
  3. Let sit for 5 to 10 minutes.
  4. Add juice from a lemon, and add honey or agave nectar to taste.

Lentinan, also known as AHCC or active hexose correlated compound, is an extract of shiitake mushrooms. It promotes antioxidant and anti-inflammatory effects at a cellular level.

A petri dish study suggests that AHCC can help with inhibiting breast cancer cells, and its interaction with the immune system might help fight cancer by improving chemo-weakened immune systems.

If you’ve found bone broth to be comforting, throw in a few chopped shiitake mushrooms next time. One study found that eating 5 to 10 g of shiitake mushrooms every day helped boost human immune systems after four weeks.

Eucalyptus oil has a component called 1,8-cineole, which may help relieve pain. The component has a morphine-like effect when tested on mice.

And for the essential oils fans, you’re in luck. Eucalyptus oil has been shown to relieve body pains even after inhalation. For lovers of Vick’s VapoRub, who have been inhaling it as a home remedy for congestion, well, eucalyptus oil is your magic ingredient.

However, inhaling eucalyptus oil isn’t for everyone. This oil can trigger asthma and may be harmful to pets. It may also lead to respiratory distress in infants.

Migraine attacks, headaches, anxiety, and general feelings of (dis)stress? Inhaling lavender can help with that. Studies shows that lavender helps with:

Drinking lavender tea or keeping a satchel around for times of high stress is one way to reduce anxiety and relax the mind and body.

As an essential oil, it can also be combined with other plant oils for aromatherapy. One study found that in combination with sage and rose, lavender was helpful in relieving premenstrual syndrome (PMS) symptoms.

Caution

While lavender is a powerful plant, it can come with side effects. Directly applying essential oil without diluting it may irritate the skin or potentially affect hormone levels. Always diffuse and dilute essential oils before use.

Mint, as common as it sounds, isn’t simple. Depending on the type, it can provide different uses and benefits.

For pain, you’ll want to look for wintergreen, which has methyl salicylate, a compound that may work similarly to capsaicin. Applying it can feel like a cool “burn” before the numbing effect takes place. This effect helps with joint and muscle pain.

The other mint type that’s commonly used in folk medicine is peppermint. An ingredient in many different cures, peppermint has been found to be especially effective in helping treat irritable bowel syndrome (IBS) symptoms.

Studies show that along with fiber, it helps reduce spasms, as well as diarrhea and abdominal pain associated with IBS. Peppermint activates an anti-pain channel in the colon, which reduces inflammatory pain in the digestive tract. This most likely accounts for its effectiveness in treating IBS.

Beyond digestion and stomach troubles, a peppermint oil capsule or tea may also help with headaches, colds, and other body discomforts.

Fenugreek seeds are often used in cooking in the Mediterranean and Asia, but this spice, which is similar to cloves, has several medicinal uses.

When made into a tea, fenugreek can help with milk production for breastfeeding. For people experiencing diarrhea, fenugreek is a great water-soluble fiber to help firm up stools. If you’re constipated, you definitely want to avoid these seeds.

As a supplement, fenugreek has also been found to lower blood sugar, making it a popular aid for people with diabetes. Fenugreek’s role here is due in part to its high fiber content, which can help with improving insulin function.

Fenugreek in cooking

Fenugreek is often ground and used in curries, dry rubs, and in teas. You can add it to your yogurt for a small savory taste, or sprinkle it over your salads.

Feeling muscle pains? Fatigue? More migraine attacks? More likely to slip into a numbed emotional state than usual? It might be a magnesium deficiency. While magnesium is often talked about in terms of the growth and maintenance of bones, it’s also essential in nerve and muscle function.

But studies show that almost half of the U.S. population doesn’t get their required amount of magnesium. So, if you’ve ever complained of these symptoms and got a slightly terse “eat spinach” response in return, know that it’s not completely unfounded.

Spinach, almonds, avocados, and even dark chocolate are all rich in magnesium. You don’t necessarily need a supplement to treat magnesium deficiency.

When it comes to mood, magnesium may also help. Magnesium works with the parasympathetic nervous system, which keeps you calm and relaxed, suggesting that having a magnesium-rich diet might aid in stress relief.

Foods high in magnesium

  • lentils, beans, chickpeas, and peas
  • tofu
  • whole grains
  • fatty fish, like salmon, mackerel, and halibut
  • bananas

While most of these natural remedies don’t have any significant side effects, they may be harmful if used in excess amounts.

Certain people may also be more sensitive to dosage amounts, so if you’re on any medication or live with a condition that’s affected by your diet, talk to a doctor before consuming these foods regularly. And if you have an allergic reaction or worsening symptoms from any home remedy, speak to a doctor right away.

Keep in mind that home remedies may not always be safe and effective for you. While these are backed by scientific studies, a single study or clinical trial doesn’t always cover diverse communities or bodies. What research notes as beneficial may not always work for you.

Many of the remedies we listed above are ones we grew up with, ones that families have passed down and brought us up on since we were children, and we look forward to falling back on them when we need the comfort.
