Nasturtium tea is a herbal infusion made from the leaves and flowers of the Tropaeolum majus plant, a species known for its bright, peppery foliage and vibrant blossoms. The idea of consuming this tea for wellness is rooted in its rich history of use in traditional medicine, particularly in South and Central America. Modern curiosity, however, drives a deeper inquiry into the science behind its purported benefits and risks.
The Rich Nutritional Profile of Nasturtium
Nasturtium, and consequently its tea, is loaded with vitamins, minerals, and bioactive compounds. A primary component is its high concentration of vitamin C, which is known for its role in supporting a healthy immune system. The plant also contains valuable minerals like manganese, iron, and calcium, alongside potent antioxidants such as lutein and beta-carotene. These antioxidants are crucial for combating free radicals and reducing oxidative stress, which contributes to overall health.
Potential Health Benefits of Nasturtium Tea
Immune System Support
For centuries, nasturtium has been revered for its immune-boosting capabilities, often used at the first signs of a cold. Its high vitamin C content, combined with flavonoids and other antioxidants, strengthens the body's natural defenses. Many herbalists recommend nasturtium tea to help fight off respiratory infections, making it a soothing drink during flu season.
Natural Antimicrobial Properties
One of the most researched aspects of nasturtium is its antimicrobial potential. The plant contains compounds called glucosinolates that, when the plant cells are crushed or chewed, release mustard oils with bacteriostatic and virostatic effects. This is why traditional medicine has used nasturtium to treat bacterial and fungal infections. In Germany, a combined product of nasturtium and horseradish is even used to treat acute respiratory and urinary tract infections.
Respiratory and Urinary Tract Health
The mustard oils in nasturtium are excreted through the lungs and urinary tract, explaining its traditional use for these systems. For respiratory issues, the tea can act as an expectorant, helping to clear mucus and ease breathing. Its antibacterial properties are particularly noted for their use in treating urinary tract infections (UTIs). The compounds work to reduce inflammation and combat bacterial imbalance in the urinary system.
Skin and Hair Vitality
Beyond internal benefits, nasturtium tea can also be used topically. The high antioxidant content and vitamin C make it a popular rinse for the hair and scalp, where it is believed to stimulate blood circulation and promote hair growth. When applied to the skin, its antiseptic and antioxidant properties can help with acne, oily skin, and even some signs of premature aging.

Important Considerations and Potential Risks
While generally safe for most healthy adults, nasturtium tea is not suitable for everyone. It is not recommended for consumption by pregnant or breastfeeding women, children, or those with kidney disease or stomach and intestinal ulcers. The presence of mustard oils can cause stomach upset in some individuals. As with any herbal remedy, it is always best to consult a healthcare professional before adding nasturtium tea to your regimen, especially if you have pre-existing health conditions or are taking other medications.
Conclusion
So, is nasturtium tea good for you? Based on its traditional use and rich nutritional profile, it offers a range of potential health benefits, particularly for supporting the immune system and addressing mild respiratory and urinary tract issues. Its high antioxidant content and natural antimicrobial compounds make it a powerful herbal ally. However, its use requires caution, and it is not a substitute for conventional medical treatment. For those who can safely consume it, this peppery, invigorating tea can be a flavorful and healthful addition to a wellness routine. Its versatility, from a simple brew to a topical rinse, solidifies its status as a valuable plant with both culinary and medicinal appeal.
A Final Note on Safety
Always ensure that any nasturtium used for tea comes from a source that is free of pesticides and other chemicals. For more information on identifying edible plants, resources from botanical societies or authoritative gardening sites are a good starting point.
