What is horseradish — and why it’s turning heads as a “health spice”
Horseradish — the sharp, sinus-clearing root from the mustard/cabbage family — is known for its intense flavour similar to Wasabi. But beyond its culinary kick, recent attention has been drawn to its potential health benefits.
According to writers at The Independent, small amounts of horseradish — such as a teaspoon of fresh root or a bit of prepared sauce — may offer surprisingly wide health benefits: from sinus relief to anti-cancer properties.
What the science says — key potential health benefits
Anti-cancer and anti-inflammation potential
Horseradish contains compounds such as Sinigrin and Isothiocyanates — plant-based chemicals also found in cruciferous vegetables like broccoli and cauliflower. These compounds may help slow or disrupt the growth of cancerous cells by inhibiting cell division or triggering cell death.
Studies in lab settings (test-tube or animal) show these compounds can protect cells from damage by harmful free radicals, potentially lowering risk of various cancers.
Because of their anti-inflammatory effects, horseradish might also help reduce chronic inflammation, a key contributor to many long-term diseases.
Antibacterial, antifungal & immune support
The same isothiocyanates that give horseradish its pungency have been shown to inhibit or kill bacteria such as E. coli, H. pylori, and Salmonella — all of which can cause food-borne illnesses.
There is also evidence suggesting potential activity against certain fungi.
Natural sinus and respiratory support
If you’ve ever felt your nose clear when eating horseradish — that’s not just the heat. The volatile compounds, especially isothiocyanates, act like a natural decongestant: they irritate nasal passages, increase mucus flow, and help clear out microbes.
This makes horseradish a traditional go-to for colds, sinus congestion or mild respiratory complaints.
Nutritional and mineral contributions
While typically consumed in small amounts, horseradish still supplies modest amounts of micronutrients including vitamin C, potassium, and other minerals that support general health.
Because it’s low in calories and fat — especially when used as a simple condiment — it can be a health-minded way to add flavour without excessive calories.
How to incorporate horseradish into your diet — safely and sensibly
A little goes a long way. Often, just a teaspoon of fresh chopped root or a small dab of prepared horseradish sauce is enough to get the flavour and possible health perks without overdoing the pungency.
Use it sparingly on meats, fish, roasted vegetables, in sauces or dips. It can replace or stand in for spicy condiments like mustard or wasabi.
Because of its strong, irritating compounds, people with sensitive digestive systems, ulcers, or inflammatory bowel conditions should use horseradish with caution.
As with many functional foods/spices: horseradish is not a magic cure. Its benefits are incremental and should supplement — not replace — a balanced diet, healthy lifestyle and medical care where needed.
Bottom line: A spicy root with promising perks — when used wisely
Horseradish isn’t just about adding punch to your food. The root harbours compounds that science suggests may support immune health, fight infections, ease sinus congestion — and even contribute to lowering cancer risk.
Used in small doses and as part of a balanced diet, horseradish can be a flavorful and functional addition to your meals. But — like all potent plants — it should be used judiciously, and with awareness of possible irritation or contraindications.
