Finger Laminaria digitata (Laminaria digitata)

Harm score: 1 (Natural substances)

The fingerling is a species of brown algae also known as kombu, kelp or sea kale. It is considered one of the most valuable marine plants and is mainly distributed in the northern hemisphere in areas with cold ocean currents. At first sight it stands out for its size, as it can grow up to several metres high. Its stems, rich in minerals, iodine and vitamins, are composed of several lateral 'fingers' resembling the shape of a hand, hence its Czech and Latin name.

It is used in many industries. It is used in cosmetics, where it is a component of many skin, hair and nail care products. Thanks to its moisturizing and remineralizing properties, it improves the elasticity and firmness of the skin and helps its regeneration. In the food industry, it is used to produce various extracts that are added to foods to increase their nutritional value. Sea kale is also traditionally eaten in Asian cuisine, where it is a popular ingredient in various soups, side dishes and omelettes. Its advantage is not only its high iodine content, but also other nutrients such as calcium, potassium and iron. Recently, the ringlet has also started to be used in agriculture as an organic fertiliser rich in minerals. Its positive effect on the soil and plant growth has been demonstrated in a number of scientific studies.
