Product Instruction

Nasturtium officinale leaf extract is extracted from plant Watercress, which is a nutritional culinary food that can also be considered a medicinal plant. The leaves have a high vitamin and mineral content and also help digestion. It has been used since the time of Hippocrates as a stimulant and expectorant in the treatment of coughs and bronchitis. Watercress can help reduce the prevalence and duration of colds when included in the diet along with garlic, onions, and cayenne. It is one of the natural food diuretics, with an action similar to parsley and asparagus. Increased consumption can help cleanse the body of toxins and water weight, while the high Vitamin C content helps your system absorb iron. Make watercress a part of your diet for health.
