Watercress Histamine Information

Watercress (Nasturtium officinale) is a green leafy vegetable rich in essential nutrients that help support overall health. Regarding its effect on histamine levels, research remains minimal. However, based on its nutritional content, potential inferences can be made. Watercress is replete with Vitamin C (ascorbic acid), a natural antihistamine. It boosts the immune system and performs a major role in managing histamine levels. As put forth in a study in the Journal of the American College of Nutrition, Vitamin C can lower histamine levels in the blood and help in breaking down histamine faster [1]. Since watercress is a good source of Vitamin C, we may infer that it potentially helps in managing histamine levels. On another note, watercress contains a substance called quercetin. This is a flavonoid with anti-inflammatory, antioxidant, and antihistaminic properties. Researchers in the Journal of Nutrition report that quercetin inhibits the release of histamine, thus reducing the symptoms of histamine intolerance such as headaches, hives, or digestive issues [2]. Given these points, it is arguable that watercress may help keep histamine levels in check. Yet, such correlation does not substitute the need for more extensive research into the effect of watercress on histamine levels. In the absence of more specific research, it should be underlined, "This product has not been researched well enough to publish any information, our team is working hard on this. Data will be available soon." References: [1] Johnston C., Martin L., & Cai X. (1992). Antihistamine effect of supplemental ascorbic acid and neutrophil chemotaxis.
