Classification
Common Names
Zostera is a fascinating genus of marine plants known by several different names across various languages and regions. Most commonly referred to as Eelgrasses, these aquatic plants are also frequently called Marine eelgrass to specify their saltwater habitat. In certain local contexts, you may encounter them referred to by the name Merihein. Additionally, the Danish name Bændeltangslægten is used to identify this specific group. Some specialized references might even use the name Nana to describe certain varieties within the genus.

Distribution
Geographic Regions
Zostera exhibits a remarkably broad distribution across the African continent, spanning from the northern coasts to the tropical east. In the north, this plant can be found inhabiting the waters of Algeria and Egypt. Its presence extends westward to the Macaronesia region, specifically around the Canary Islands. Moving toward the eastern coast, the species thrives within the tropical waters of Kenya. Finally, its range continues southward through the coastal regions of Tanzania.

Identification
Biological Activities
Zostera belongs to a group of marine organisms that have been investigated for their potential antihypertensive activity. A systematic review and meta-analysis of randomized controlled trials recently evaluated the impact of algae supplements on human blood pressure. While the effects on systolic blood pressure remained inconclusive, the findings revealed a significant reduction in mean diastolic blood pressure for the treatment group. These results suggest that certain algae extracts may play a role in managing hypertension, though the evidence is not yet definitive. Consequently, more large-scale clinical trials are necessary to fully confirm the therapeutic benefits of these marine supplements.
Compounds
Conditions
Zostera, specifically through its polysaccharide preparation known as zosterin, demonstrates significant antibacterial effectiveness against a wide range of pathogens. The preparation markedly inhibits the growth of both Gram-negative and Gram-positive organisms in vitro. Among the specific bacteria targeted, zosterin effectively treats E. coli and S. aureus. It also shows potent activity against Ps. aeruginosa. These results highlight the diverse therapeutic potential of this sea grass against various microbial threats.
Preparations
Zostera is prepared as capsules to facilitate its administration in various studies. These capsules typically range in dosage from 500 mg to 8 g to evaluate physiological impacts. Such preparation methods allow researchers to study the effects of marine organisms on human health metrics. By using this specific delivery format, the duration of follow-up can be tracked from 17 days to 9 months. This capsule form is essential for quantifying the antihypertensive activity of the organism.
