Here are the details of the herbal plant and its local names in Nigeria
The Ghanaian government has approved a herbal medicine, Cryptolepis sanguinolenta, locally known as Nibima, for clinical trials.
The plant, which grows freely across sub-Saharan Africa has different local names and it has been used for ages in the treatmentif malaria. In Nigeria it is called Paran pupa (Yoruba), Gangnamau (Hausa) (Osafo et al., 2017) and Akpa-oku (Igbo). C. sanguinolenta is basically responsible for anti- plasmodial activity.
The roots of cryptolepis, also known as nibima, kadze, gangamau, Ghanaian quinine and yellow-dye root (Cryptolepis sanguinolenta) have been used in Ghanaian traditional medicine for treatment of malaria for many generations.
A statement issued by the Ghana Food and Drugs Authority (FDA) late January said, ‘In search for a treatment for the ongoing Covid-19 pandemic, researchers from the School of Public Health at the Kwame Nkrumah University of Science and Technology, (KNUST), submitted a clinical trial application in September 2020 to assess the safety and efficacy of Cryptolepis sanguinolenta as a potential treatment for Covid-19. This follows results from laboratory studies conducted by the KNUST research team which points in the direction of possible clinical benefits.’
The FDA Ghana is listed as a World Health Organisation (WHO) ‘Maturity Level 3’ Regulatory Agency, the second country in the WHO African Region to attain this level in the four-tier WHO classification of National Medicines Regulatory Systems. This level, the second within this classification, indicates that Ghana’s medicines regulatory system is well functioning and integrates all required elements to guarantee its stable performance, thereby ensuring the safety, quality and efficacy of all medical products imported, exported, manufactured or distributed in the country including the regulation of the conduct of clinical trials.
‘The FDA after detailed assessment of the application gave the requisite regulatory authorization for the conduct of the trial as per the mandate outlined under Part 8 (Sections 150 -166) of the Public Health Act 2012 (Act 851 ), which gives the Authority the legal mandate to regulate clinical trials of drugs, herbal medicinal products, cosmetics or medical devices. The trial will be conducted at two sites,’ the statement added.
The research team has over the years been involved in FDA’s stakeholder engagements and capacity building activities and has an in-depth experience as well as the knowledge in international and national regulatory requirements requisite for the effective conduct of clinical trials. The sites have adequate capacity to ensure the safety of participants as well as produce credible scientific data.
