Horsetail kelp
Laminaria digitata
Laminaria digitata is a brown seaweed commonly found along the coasts of Europe and North America. Traditionally, its use has not been extensively documented in any specific medical or folk traditions. Scientific studies have identified various components within Laminaria digitata, including isomers of singly and doubly sulfated fucose, and singly sulfated galactose within fucoidan, which may play a role in cellular storage mechanisms involving iodide and bromide. Research has also shown that both enzymatically processed and unprocessed Laminaria digitata and Fucus vesiculosus increased the relative abundance of certain bacterial species and pathways related to glucose breakdown in inflamed mice, suggesting potential anti-inflammatory effects. However, the study on tomato yield and biostimulant effects was unrelated to Laminaria digitata's biological activity. No major safety issues or recorded drug interactions have been identified for Laminaria digitata thus far.

What the science says
- The study found that iodide is stored in intracellular vesicles and bromide in vacuoles of specific cells in Laminaria digitata.
- Both enzymatically processed and unprocessed Laminaria digitata and Fucus vesiculosus increased the relative abundance of certain bacterial species and pathways related to glucose breakdown in inflamed mice.
- The study found that reduced irrigation primarily affected yield structure and fruit composition in greenhouse tomatoes, with biostimulants showing variable effects depending on water availability.
- The study identified isomers of singly and doubly sulfated fucose, and singly sulfated galactose within fucoidan from Laminaria digitata using cIM-MS.
- The study found that mechanical blade disruption and pretreatment duration influenced alginate yield and purity, with optimal conditions varying by processing time and speed.
