Isirgan, also known as dalagan or dalan, is one of the oldest known herbs. Having been used for centuries in cooking and homeopathic remedies, Isirgan leaves and roots are believed to have different applications. Those working with the herb should be sure to wear gloves as the leaves have tiny spikes, a naturally occurring defense mechanism. People often drink tea brewed from the leaves, believing it to help with lung infections, colds, the digestive system and even measles. The leaves are further believed to have anti-inflammatory properties and can be used as a poultice for sore muscles. In Türkiye, the traditional method of preparing Isirgan is as a soup. The leaves are collected and washed before being cooked in a simple stock mixture, then blended. The soup is a shocking green colour, traditionally made in the spring when the leaves are young and tender. Isırgan is also commonly sautéd with olive oil and onions.
