What is Horseradish?

Horseradish (Cochlearia Armoracia or Armoracia Rusticana) is a root vegetable that tastes very pungent and spicy.

Horseradish consists of the root part and green leaves that have white flowers. The most popular way of consuming horseradish is prepared horseradish that is preserved in vinegar.

Horseradish is so hot and spicy because enzymes combine together when the root is chopped or grated. Enzymes such as myrosinase, sinigrin, and gluconasturtiin combine to create a type of hot mustard oil that has a pungent aroma and taste. (1)

The journal Biofactors reports that horseradish belongs to the same family as wasabi (Wasabi japonica). Scientists have found that these are functional foods which are full of antioxidants that promote good human health. (2)

Freshly grated or chopped horseradish doesn’t last a long time. If you want to use fresh horseradish for its health benefits, you should consume it immediately. You can also mix horseradish with some apple cider vinegar, water and some salt to taste and store in the fridge. This helps to make horseradish last longer.

Nutritional Value of Horseradish

Horseradish is an extremely nutritious root vegetable with spicy overtones. Adding freshly grated horseradish to your food will not only spice it up but also improve its nutritional content.

Research into the nutritional benefits of horseradish root has found that it is rich in vitamins, minerals, antioxidants, and isothiocyanates. These are enzymes that make horseradish root so hot and pungent. (3)

Horseradish contains minerals such as potassium, calcium, magnesium, sulfur, and copper. (4)

There are also many vitamins in horseradish. One of the biggest benefits of eating fresh or prepared horseradish is that it contains high levels of vitamin C. The vitamin C content of horseradish can be up to 350 mg per 100 g of fresh horseradish root. (5)

However, horseradish leaves contain even higher levels of vitamin C. Scientists have found that the horseradish plant leaf contains a 4-fold higher content of vitamin C than the root.

According to the United States Department of Agriculture, one tablespoon of prepared horseradish contains 7 calories and 1.7 g of carbs. (15)

The root and leaves of horseradish contain a powerful antioxidant called ally isothiocyanate which is the hot component that develops when you grate horseradish. (2)

Can you use horseradish to help lose weight faster? Horseradish is naturally low in calories, and contains high amount of fiber. For example, a tablespoon (15 g) of horseradish contains 0.5 g of fiber which is 2% of your recommended daily fiber intake. (15)

The book Antioxidant Properties of Spices, Herbs, and Other Sources reports that the nutritional value of horseradish means that it is good for a number of medicinal uses. Horseradish is good for killing off microbes and germs and relieving muscle spasms. (3)

Why Is Horseradish So Good for You? Proven Benefits of Horseradish

What are the many reasons why it’s good to consume more horseradish in your diet? Let’s look in more detail at the benefits of horseradish root.

Horseradish Helps to Treat Sinus Infections

Horseradish contains antibacterial compounds that can help treat the symptoms of sinusitis.

Sinus infections cause inflammation and swelling in your forehead, under your eyes, and in your nasal passage. Sinusitis can be the result of the cold, flu, or allergic reactions. (6)

In one cohort study involving over 850 children, a natural remedy containing horseradish root helped to get rid of sinusitis quicker. The herbal horseradish remedy prevented the use of antibiotics to clear up the sinus infection. The researchers found that treating sinus infections with horseradish had fewer symptoms than with antibiotics. (7)

Another great reason to use horseradish for a sinus infection is that it contains vitamin C and phenolic compounds. Many studies point to the fact that these antioxidants are necessary to strengthen your immune system to fight infections better. (8, 9)

Because horseradish is so good for loosening mucus blocking your sinuses, you can also use horseradish for treating colds and flu.

Horseradish Extracts Can Help Cure Bronchitis

One of the horseradish root benefits is to get rid of congestion and clear respiratory infections.

Scientific research into the medicinal properties of horseradish has found that it has anti-inflammatory and antibacterial properties. Researchers have found that the horseradish enzyme sinigrin creates the compound ally isothiocyanate. This compound is anti-inflammatory and the reason why horseradish is so spicy hot. (10)

Researchers say that the health-boosting effect of horseradish means that it is good for treating bronchial infections.

For example, scientific research has found that horseradish root extract blocks COX enzymes. COX-2 enzymes are often the cause of inflammatory responses in the body like bronchitis. Horseradish extracts act like non-steroidal anti-inflammatory (NSAID) drugs that can help to treat the symptoms of respiratory infections. (11)

Horseradish Root Has Antibacterial Properties and May Clear Up Urinary Tract Infections

Horseradish is very good for women and men because it benefits your urinary system.

Urinary tract infections occur when bacteria enter your urinary tract and cause symptoms like burning when you pee, smelly urine, and lower abdominal pain.

Scientists report that treating some urinary tract infections (UTIs) is becoming more challenging due to multidrug-resistant bacteria.

Research has shown that horseradish is good for treating UTIs. Lab trials have shown that horseradish extracts can help to destroy E. coli strains of bacteria and could be an alternative treatment for urinary tract infections. (12)

Other studies have confirmed that a combination of the herb nasturtium and horseradish help to treat recurring UTIs in humans. (13)

Natural remedies containing horseradish powder may also help to prevent recurrent urinary tract infections in children. (14)

Horseradish Can Reduce Joint Inflammation and Treat Muscle Pain

The medicinal and anti-inflammatory properties of horseradish mean that horseradish extracts are good for getting rid of pain.

Research published in 2015 found that compounds and enzymes in horseradish extracts help to block reactive oxygen species. These are enzymes connected to inflammation in the body. At the same time horseradish also stimulated certain compounds that help to reduce inflammation. (16)

Other studies have pointed to the fact that horseradish extracts act in a similar way to pain relievers like ibuprofen or aspirin. (10)

Find out how you can use horseradish as a spicy accompaniment to other foods that help to reduce inflammation.

Horseradish Can Help with Treating Water Retention

Compounds in horseradish root can help to reduce the buildup of excess fluid or edema in your body.

The reason that horseradish is good for treating water retention issues is due to the compound sinigrin. Researchers say that sinigrin is a sulfur-containing species that is abundant in horseradish and wasabi. (17)

Studies into sulfur-containing glucosinolates such as sinigrin have found that they can alleviate water retention (edema) due to consuming too much salt. (18)

Find out some of the many ways you can shed water weight naturally and prevent water retention.

Horseradish Acts as a Diuretic

Horseradish could be good to take if a buildup of fluid in your body leads to high blood pressure.

Diuretics help to pass more salt and urine from your body to help reduce edema. According to research, horseradish acts as a natural diuretic. Therefore, consuming more horseradish may help to prevent water retention and lower blood pressure. (3)

Horseradish Has Anticancer Properties

Many functional foods such as horseradish that contain sulfur compounds and antioxidants have therapeutic properties that are useful in treating cancer.

The Journal of Agricultural and Food Chemistry reported that horseradish root extracts are COX inhibitors that inhibit the spread of tumor cells. Researchers have found that compounds in horseradish help to protect against colon cancer, lung cancer, and stomach cancer. (19)

Other studies have found that allyl isothiocyanate in horseradish has antioxidant and anticancer activity. These chemo-preventative compound can help to inhibit bladder cancer cell growth. (20)

Of course, more research needs to be carried out to see how functional foods such as horseradish can help to prevent, treat, and cure cancer.

Benefits of Horseradish Leaves

Many people overlook the health benefits of consuming horseradish leaves. However, adding horseradish leaves to your meals can help to boost your immune system.

Horseradish leaf has a strong, peppery taste that can really add some spice to a delicious fresh vegetable salad if used in small amounts.

One of the reasons to consume horseradish leaves is that there is also a lot of vitamin C in the leaf.

Research has shown that young horseradish leaves have the highest vitamin C content. The vitamin C content of horseradish leaf is around 350 mg for every 100 g of fresh leaf. Leaves from the horseradish plant have 4 times the amount of vitamin C than the root. (5)

Side Effects of Horseradish

Most people can safely consume horseradish as an accompaniment to their meal.

Doctors from WebMD say that taking larger doses of horseradish is usually tolerable by most people. However, the spicy mustard oil in horseradish can cause digestive upset and irritation in the mouth and throat. (21)

If you have underlying digestive problems like inflammatory bowel disease or peptic ulcers, you should avoid horseradish as it may irritate your gastrointestinal tract.

Also, pregnant women or people with kidney problems should stay away from horseradish, horseradish extracts, or horseradish oil. This is because large doses of horseradish can cause miscarriage and make kidney problems worse.

Recommended Daily Intake of Horseradish

The German Commission E monograph (Therapeutic Guide to Herbal Medicines) suggests an average daily intake of 1/2–1 teaspoon (3–5 grams) of the freshly grated horseradish three times per day. If used in amounts higher than recommended, horseradish can cause stomach upset, vomiting, or excessive sweating. (22)

Horseradish Recipes to clear your nose and chest

There are several ways to use horseradish, but my preference is to eat it raw and fresh: grate it and mix it with other healing ingredients, such as apple cider vinegar or honey.

It is important to consume horseradish fresh or it will lose its potency. Also, it’s best to use it raw, as cooking destroys some of its beneficial substances and takes away its signature refreshingly spicy taste.

To get a better idea about how to use horseradish, have a look at the recipes below. Also, we might sometimes be eating horseradish without even being aware. Did you know that ‘wasabi’ served in many sushi restaurants is in fact dyed horseradish? They taste similar and they both give you that famous kick, but horseradish is much easier to find compared to the scarce wasabi, so it’s often served to the unaware costumers.

Horseradish sinus plumber

Use a vegetable peeler to peel the surface skin off of the tuber and chop into small pieces.
Put into the food processor, add the water, the vinegar and the salt.
Process until well ground.

At the point you have to be extremely careful as the ground up fresh horseradish is many times as potent as chopped onions and it can seriously hurt your eyes if you get too close. Always keep an arm length away and work in a well ventilated area.

Store in a glass jar and eat 1/2–1 teaspoon (3–5 grams) three times per day. This is a seriously strong concoction which I’ve used myself and found it extremely effective. If you haven’t eaten horseradish before start with very small amounts as this is extremely strong and potent concoction.

It will keep 4-5 weeks in the refrigerator.
