Nasturtium: What It Is, Why It Matters, and How to Use It

Nasturtium is a bright‑colored herb that grows in many gardens. Its leaves, flowers, and seeds are all edible, and each part brings a sharp, peppery taste. People like it because it’s cheap, easy to grow, and packed with nutrients that can help your body. Below you’ll find the most useful facts about nasturtium, plus simple ideas for adding it to your meals and daily routine.

Nutritional Profile and Health Benefits

One cup of fresh nasturtium leaves delivers more vitamin C than an orange. It also contains vitamin A, potassium, and iron. Those nutrients support the immune system, keep eyes healthy, and help blood cells carry oxygen.

What makes nasturtium stand out is its high level of glucosinolates. When you chew the leaves, your body turns these compounds into isothiocyanates, which have been shown to fight inflammation and protect cells from damage. In practical terms, that means regular nasturtium could ease joint soreness and support a healthy gut.

Some studies suggest that the antibacterial properties of nasturtium help keep unwanted germs in check. If you add the herb to a salad or a sandwich, you’re not just adding flavor—you’re also giving your digestive tract a mild boost against harmful bacteria.

People with low iron often look for plant sources, and nasturtium’s iron content can complement other iron‑rich foods. Pair it with vitamin C‑rich fruits like strawberries to improve iron absorption.

While nasturtium is safe for most folks, a few points deserve attention. The plant can act as a mild diuretic, so drinking enough water is wise. If you take blood‑thinning medication, talk to a doctor before loading up on large amounts because the vitamin K in the leaves might interfere with the drug.

How to Use Nasturtium in Everyday Life

Adding nasturtium to your plate is easier than you think. Toss raw leaves into salads for a peppery kick that replaces arugula. Sprinkle whole flowers on top of pizza, tacos, or grain bowls for color and a pop of flavor.

If you prefer a milder taste, blanch the leaves briefly in hot water. This softens the peppery bite while keeping most of the nutrients. Use the softened leaves in soups or omelets for a subtle, fresh twist.

Nasturtium seeds can be harvested, dried, and cracked like pepper. Sprinkle the seed “pepper” on roasted vegetables, fish, or avocado toast for a zingy finish.

For a quick herb‑infused drink, steep a handful of leaves in hot water for five minutes. The resulting tea tastes like a mix of mint and pepper and can be enjoyed hot or iced. Some people sip it to soothe a sore throat or support digestion after a heavy meal.

Growing nasturtium at home doesn’t require a green thumb. Sow the seeds directly in garden soil or a pot, water sparingly, and let the plant spread. Within weeks you’ll have a living source of flavor right on your balcony.

Remember, the key to enjoying nasturtium is balance. Use a small handful in a dish, taste, and add more if you like the zing. Overdoing it can make a meal too spicy, especially if you’re new to the herb.

Bottom line: nasturtium offers a tasty way to get extra vitamins, support your immune system, and enjoy a natural anti‑inflammatory boost. Whether you sprinkle its leaves on a salad, brew a soothing tea, or grow it in your garden, this bright herb can become a go‑to ingredient for healthier, more vibrant meals.
