BACKGROUND
Debregeasia salicifolia Rendle (DS) is used traditionally for the treatment of several diseases including; urinary system diseases, bone fractures, boils, diarrhea accompanied with blood, carbuncles, pimples, dermatitis, skin rash, eczema, and tumors. Additionally, it is used as an antiseptic and antifungal agent.
OBJECTIVE
To document up to date information regarding D. salicifolia and link the traditional uses with its reported pharmacological evidences. The review covers taxonomy, distribution, traditional uses, active phytochemical constituents and pharmacological activities for DS.
METHODS
The electronic databases such as Google Scholar, E-Resource Portal of Imam Abdulrahman bin Faisal University, Scopus, PubMed, Springer Link, etc. as well as textbooks were used to gather all relevant information about DS.
RESULTS
Ethnomedicinal studies revealed a wide use of DS for various traditional purposes in the south Asian community. The uses for diarrhea, cancer, urinary complaints and skin diseases were supported by pharmacological studies. In-vitro pharmacological studies confirmed its therapeutic activities e.g. antimicrobial, anticancer, and antioxidant. Moreover, analgesic and anti-diarrheal activities were also established in animal's in-vivo activities. Despite enormous literature regarding DS, the main focus of research and interest was antimicrobial and cytotoxic activities. Quantitative and qualitative phytochemical analysis proved the presence of various classes of phytochemicals in DS extract; triterpenes, phytosterols, tannins, flavonoids and anthraquinone.
CONCLUSIONS
Though most of the traditional uses for the plant were supported by in-vitro and in-vivo pharmacological studies, however lack of clinical trials and shortage of in-depth mechanistic in-vivo studies was noted in the review. Hence, more elaborative in-vivo studies with quality clinical trials may be focused in order to confirm the safety and efficacy of reported activities in humans which will help explore the plant's therapeutic potentials.
