Ekebergia capensis is an integral part of indigenous pharmacopeia in tropical Africa. The present study critically reviewed the ethnomedicinal uses, phytochemistry, and pharmacological properties of E. capensis. The keywords including E. capensis, its synonyms, English common names, ethnomedicinal uses, and phytochemistry and pharmacological properties of the species were searched using electronic databases such as ISI web of knowledge, ProQuest, science direct, OATD, Scopus, Open-thesis, PubMed, and Google Scholar. Pre-electronic literature of conference papers, scientific articles, books, book chapters, dissertations, and theses was carried out at the University Library. Literature studies revealed that E. capensis is mainly used as herbal medicine against fever and malaria, gastrointestinal problems, pain, parasitic worms, reproductive problems in women, respiratory problems, and skin diseases. Phytochemical compounds identified from the species include alkaloids, anthraquinones, coumarins, flavonoids, glycoflavonoids, glycosides, iridoids, limonoids, polyphenols, phytosteroids, pregnane, saponins, tannins, and withanolides. Pharmacological studies revealed that E. capensis extracts and compounds have acetylcholinesterase-inhibitory, analgesic and anti-inflammatory, anthelmintic, antibacterial, antifungal, antigonococcal, antimycobacterial, antimycoplasmal, antihypertensive, antioxidant, antimalarial and antiplasmodial, antischistosomal, antitrypanosomal, and antiviral and cytotoxicity activities. Although pharmacological evaluations carried out so far have confirmed the potency of E. capensis crude extracts and compounds, detailed studies are required aimed at establishing the efficacy, clinical relevance, safety, and mechanisms of action of the plant extracts and compounds.

The current study critically reviewed the medicinal uses, phytochemistry and biological activities of H. odoratissimum. Information on medicinal uses, phytochemistry and biological activities of H. odoratissimum were collected from multiple internet sources which included Scopus, Google Scholar, Elsevier, Science Direct, Web of Science, PubMed, SciFinder, and BMC. Additional information was gathered from pre-electronic sources such as journal articles, scientific reports, theses, books, and book chapters obtained from the university library. This study showed that H. odoratissimum is mainly used as an herbal medicine for insomnia, menstrual pain and sterility, and wounds and respiratory problems. Pharmacological research revealed that H. odoratissimum extracts and compounds isolated from the species have antibacterial, antimycobacterial, antifungal, anti-inflammatory, antioxidant, hepatoprotection, and hypoglycemic and cytotoxicity activities. There is a need to validate the documented ethnomedicinal uses of H. odoratissimum through phytochemical and pharmacological studies. Therefore, future studies should address these knowledge gaps through experimental animal studies, randomized clinical trials, and target-organ toxicity studies involving H. odoratissimum crude extracts and compounds isolated from the species.
