Deep Dive
Nasturtium works primarily through a compound called gluconasturtiin. When you eat it, this hydrolyzes into asturtin, a flavonoid known for its antimicrobial properties. Research suggests that Nasturtium extracts can inhibit the growth of bacteria like Staphylococcus aureus and E. coli.
For the respiratory system, it acts as a mild irritant to the stomach lining, which reflexively increases fluid secretion in the respiratory tract (mucus). This may sound counterintuitive, but it actually helps thin and expel phlegm, making it easier to breathe during colds or bronchitis. It is often paired with Horseradish in herbal remedies (like Angocin) to enhance this effect.
Natural Food Sources
Nasturtium is unique because the entire plant is edible. Unlike synthetic supplements, eating the plant provides a full spectrum of synergistic nutrients.
| Food Source | Part Used | Flavor Profile | % DV (Vitamin C) |
|---|---|---|---|
| Nasturtium Leaves | Raw | Peppery, Arugula-like | ~45% |
| Nasturtium Flowers | Raw | Mildly Spicy | ~15% |
| Nasturtium Seeds | Pickled | Capers-like | N/A |
