Sea cucumber as a therapeutic aquatic resource for human health

Abstract

Sea cucumbers are worm-like, leathery bodied, benthic, marine organisms with a branched gonad. There are over 900 species, and these organisms are capable of changing their mechanical state, regenerating their small appendages, and digestive tract. Additionally, sea cucumbers possess both commercial and therapeutical value. Furthermore, it is thought that the metabolites these organisms possess may give rise to their therapeutical value. The use of sea cucumbers in therapy can be traced back to the Ming dynasty, where they were eaten for their tonic properties against constipation, hypertension, and rheumatism. A plethora of studies have been conducted, whereby different metabolites were extracted from sea cucumbers and tested for different therapeutic properties. Herein, we review and discuss the anti-cancer, anti-microbial, anti-coagulant, anti-diabetic, antioxidant, and anti-inflammatory properties of the sea cucumber by assessing literature on PubMed and Google Scholar. Furthermore, the genome and epigenome of these remarkable species is discussed. With the immense data supporting the therapeutic properties of sea cucumbers, further studies are warranted, in order to develop novel and innovative therapeutic compounds for the benefit of human health from these fascinating marine organisms.
