The horseradish plant is native to Eastern Europe. Known for its pungent odor it is less known for its traditional uses. The component in horseradish known to cause this familiar odor is also suggested to be the reason behind many of the traditional benefits attributed to the plant.
Horseradish contains several nutrients such as Vitamins C and B1, iron, calcium, magnesium and potassium. The main component is sinigrin.
This article discusses the uses of horseradish. In addition, it also looks at the components of horseradish and any precautions to its use.
Uses of Horseradish
Supplement use should be individualized and vetted by a healthcare professional, such as a registered dietitian, pharmacist, or doctor. No supplement is intended to treat, cure, or prevent disease.
Horseradish contains vitamins C and B1, iron, calcium, magnesium, potassium, and sinigrin. Also present in horseradish are flavonoids. Besides being used as a table condiment, these components in horseradish may explain the traditional uses of horseradish.
Antibacterial
Horseradish has also been used in traditional medicine as an antibacterial. With the increased resistance to antibiotics, scientists are searching for new ways to respond to bacteria’s potential effects on the human body. For this reason, they have started studying the components (chemicals) from the horseradish plant.
The sinigrin found in horseradish releases allyl isothiocyanate, a sulphur-containing mustard oil. It is the activity of the isothiocyanates that acts against bacteria such as Escherichia coli. This has motivated the need to further study the activity of horseradish and its effects on bacteria.
Early studies show that horseradish may have antibacterial properties. But, again, the data is not sufficient to support the claims. More clinical studies (studies in humans) are necessary to produce the data needed to support these statements.
Urinary Tract Infection
Urinary tract infections are common infections affecting all ages and genders. Managing this illness is essential due to its widespread impact.
The activity of an isothiocyanate (a chemical) may promote the antimicrobial (germ-killing) activity of the horseradish plant. These studies, too, are in the early stages. Human data is needed to support these claims.
Cancer
Clinical (human) studies have not been done to study the use of the horseradish plant for cancer.
Sinigrin, a result of the degradation of glucosinolates, has been shown to cause death in some cancer cells. Though these early results are promising, no clinical data exists to support these claims.
As with most supplements, more research is necessary to support the claims of traditional uses for horseradish. Besides those listed above, other traditional uses for horseradish include:
Inflammation Blood pressure regulation Gout Kidney Stones Asthma Rheumatism Headaches Chest congestion Muscle stiffness
What Are the Side Effects of Horseradish?
Horseradish comes with several possible side effects, which you should be aware of. The majority of the side effects are common side effects.
Common Side Effects
Stomach upset Vomiting Excessive sweating Irritation or burning of the skin/eyes
Severe Side Effects
Severe side effects of horseradish are rare. Clinical data about the side effects of horseradish are lacking. As with any supplement, there is a risk of an allergic reaction. Anaphylaxis is a severe allergic reaction that can be life-threatening.
If you should experience any change in condition when using horseradish, consult with your healthcare provider.
Precautions
While it is generally safe to use horseradish, some areas require caution. People with hypothyroidism, peptic ulcers, gastritis, and kidney disease are not recommended to use horseradish. If you have any of these conditions, it would be best to speak with your healthcare provider about your individual use of horseradish.
It is also not recommended to use horseradish at therapeutic levels during pregnancy or breastfeeding. It’s also not recommended for use by children under four years old.
Dosage: How Much Horseradish Should I Take?
Always speak with a healthcare provider before taking a supplement to ensure that the supplement and dosage are appropriate for your individual needs.
Horseradish can come in many different forms. Follow the label recommendations when taking any of the forms.
The fresh root of horseradish should be taken before meals. Take 3-4 grams daily. The dried root can be taken in 20 grams per day. As an infusion and syrup, horseradish can be taken in 2-gram doses several times per day. Horseradish can be prepared in a tincture. Take 2-4 grams of the dried equivalent per day as a tincture.
What Happens if I Take Too Much Horseradish?
Horseradish is considered generally safe. But sometimes too much of a good thing is not really good at all. Horseradish can be toxic if eaten in high quantities. It is best to take small quantities when using in this condiment or supplement.
The toxic part of the plant can be found in the root. It is the glucosinolates found in the root that are the culprits of this risk of toxicity. When eaten in high quantities it can cause profuse sweating, stomach upset, weakness, and disorientation.
Should you being to experience any of these symptoms when using horseradish, seek medical help immediately.
Interactions
There are no recent reports of horseradish having any drug interactions. There is mention that horseradish may interact with thyroid medications such as levothyroxine because of the possibility of decreasing thyroid activity.
Because of this uncertainty, if you take levothyroxine, it is best to speak with your healthcare provider before using horseradish.
It is essential to carefully read a supplement’s ingredient list and nutrition facts panel to know which ingredients and how much of each ingredient is included. Please review this supplement label with your healthcare provider to discuss potential interactions with foods, other supplements, and medications.
How to Store Horseradish
Follow all storage and discard recommendations found on the supplement label. Fresh horseradish is best stored in the refrigerator. When the supplement is fresh, keeping it in the refrigerator will minimize the loss of flavor and maintain its quality.
Horseradish is available in freeze-dried and dehydrated forms. In these forms, follow the recommendations for storage found on the supplement label.
Similar Supplements
Several supplements are used to address urinary tract infections. Horseradish, traditionally used to address urinary tract infections, is similar to supplements such as:
Watercress (Nasturtium Officinale)Flagroot (Acorus calamus)Caper (Capparis spinosa)Siamese-ginger (Alpinia galanga)
When taking horseradish, it is best to speak with your healthcare provider about taking it along with any of the above supplements.
Sources of Horseradish and What to Look For
Horseradish can be found in many forms. It is available as a spicy food condiment or as a supplement. The best way to receive the benefits of horseradish is through a supplemental form.
Horseradish Supplements
Horseradish supplement is available in many forms. The actual root, of which most supplements are made, can be purchased at grocery stores.
The supplement can be found as a tincture, infusion, or syrup. These preparations are likely higher in concentration than you would receive from just increasing horseradish in your diet naturally.
Summary
The horseradish condiment that may be on your kitchen table has more uses than spicing things up. Traditional medicine has used horseradish to act on many health issues from infections to inflammation. Early studies on some of these traditional uses may be promising, but more data from research in humans is needed to support the traditional uses of horseradish.
