Young leaves of common starwort are edible, raw or cooked as a potherb. They may be available all year round if the winter is not too severe. Very nutritious, they can be added to salads while the cooked leaves can scarcely be distinguished from spring spinach. The leaves contain saponins so some caution is advised. Although toxic, these substances are very poorly absorbed by the body and so tend to pass through without causing harm. They are also broken down by thorough cooking. Saponins are found in many plants, including several that are often used for food, such as certain beans. It is advisable not to eat large quantities of food that contain saponins. The seeds can be ground into a powder and used in making bread or to thicken soups. It would be very cumbersome to harvest any quantity of these seeds since they are produced in small quantities throughout most of the year and are very small. The seed contains 17.8% protein and 5.9% fat. Composition of leaves (dry weight) in milligrams per 100g weight of food: Vitamin A: 30, Thiamin: 0.02, Riboflavin: 0.14, Niacin: 0.51, Vitamin C: 375.
