Indication
The abundance of mineral salts makes fucus a mineralizing plant. Because of its mucilage content, it has an appetite satiating effect, and it has been found that fucus and other brown algae inhibit α-amylase and α-glucosidase enzymes that are essential for the assimilation of some carbohydrates.
Properties
The European Medicine Agency (EMA) recommends its traditional use as an adjunct to low-calorie diets to help weight loss in overweight adults, only after the presence of serious diseases has been excluded by a doctor.
Another study suggests the possible use of fucus in alleviating the symptoms of skin aging, by preventing the reduction of the thickness of the dermis and to increase its elasticity.
