Applications
Nasturtium for Infections
Nasturtium is a true broad-spectrum antibiotic found in nature. Its mustard oils have antibacterial effects against Gram-positive and Gram-negative bacteria, antiviral effects against viruses, and antifungal effects against fungi—acting systemically when taken internally and topically when applied externally. When taken several times a day for acute infections, the active ingredients reach all the mucous membranes in the body.
Tropaeolum majus for muscle pain
When applied topically, the mustard oils in nasturtium intensively stimulate blood circulation in the muscles and fascia. This improved circulation delivers more oxygen and nutrients to the tissues and accelerates the elimination of metabolic waste products. Tense muscles relax, and the fascia becomes more flexible.
Nasturtium for Urinary Tract Infections
E. coli is the most common cause of urinary tract infections—and nasturtium seed oils are particularly effective against this pathogen. They kill the bacteria directly while also improving blood flow to the bladder lining, allowing the body’s natural defenses to function optimally. When taken several times a day in acute cases, burning, itching, and the urge to urinate disappear.
Tropaeolum majus for tonsillitis
Tonsillitis is often caused by streptococci—and it is precisely these pathogens that are effectively combated by the mustard oils found in nasturtium. The antimicrobial effect reaches the mucous membranes of the throat directly. The inflammation subsides, and swallowing becomes easier again.
Nasturtium for mucosal inflammation
Inflammation of the mucous membranes—whether in the mouth, throat, intestines, or urogenital tract—is caused by pathogens or irritants. The mustard oils in nasturtium have an antimicrobial effect against a broad spectrum of pathogens on all mucous membranes and an anti-inflammatory effect on the affected tissue. The pathogens are combated, and the inflammation subsides.
Tropaeolum majus for colds
When you have a cold, viruses and bacteria infect the entire nasal-pharyngeal-bronchial tract. The mustard oils in nasturtium attack these pathogens on multiple fronts: they have antibacterial and antiviral effects against the pathogens, improve blood circulation in the tissues, and provide vitamin C to support the immune system. This helps shorten the duration of the cold and make its symptoms milder.
Nasturtium for Acne
Acne is caused by inflammation of the sebaceous glands, which is often triggered or exacerbated by staphylococci on the skin. When applied topically, the mustard oils in nasturtium directly combat the bacteria responsible. Inflammation of the pores subsides, new breakouts occur less frequently, and the skin’s appearance improves.
