[Sejong=Asia Economy Reporter Moon Chaeseok] The Ministry of Oceans and Fisheries announced on the 1st that it has discovered the efficacy of Sargassum horneri extract, a seaweed massively inflowing from China, in preventing or treating psoriasis, an inflammatory skin disease.


A joint research team from the National Marine Biodiversity Institute under the Ministry of Oceans and Fisheries and Inje University College of Medicine administered imiquimod, a drug that stimulates the immune system to induce psoriasis, to experimental mice. Subsequently, by additionally administering Sargassum horneri extract, they confirmed a significant reduction in factors causing psoriasis and an improvement in psoriasis symptoms.


According to the research team, existing psoriasis treatments using steroid drugs can cause various side effects such as capillary dilation and skin atrophy when applied for a long time. In contrast, Sargassum horneri extract is a natural substance without side effects, showing great potential for development as a preventive or therapeutic agent for psoriasis.


The research team has completed a patent application for these findings. The Marine Biodiversity Institute plans to support further research with private companies to commercialize Sargassum horneri extract as a pharmaceutical material and other uses.



Sargassum horneri, scientifically named 'Sargassum horneri,' is a perennial brown algae belonging to the Sargassaceae family. Several branches extend from a small cushion-shaped holdfast, typically growing to 3?5 meters in size. At depths of about 40?60 meters, it can grow over 10 meters. Most Sargassum horneri entering Korea are believed to have detached from rocks along the Chinese coast due to waves or wind, occurring in large quantities usually between March and June.
