Evaluation of packaging, labels, and some physicochemical properties of herbal antimalarial products on the Ghanaian market. Heliyon 2024; 10:e27032. [PMID: 38463810 PMCID: PMC10920373 DOI: 10.1016/j.heliyon.2024.e27032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2023] [Revised: 02/22/2024] [Accepted: 02/22/2024] [Indexed: 03/12/2024] Open
Abstract
Introduction Malaria is a parasitic disease that is endemic in tropical areas and can be life-threatening. There has been a decrease in the prevalence of malaria in Ghana but the burden of the disease is still high in the country. Many Ghanaians depend on herbal products for malaria treatment. This study aimed to survey and evaluate commercial herbal antimalarials in the Volta Region of Ghana. Methods A survey of finished herbal antimalarials was done at herbal shops, pharmacies, and over-the-counter medicine seller shops. Products available on shelves were purchased and their details were recorded, after which they were examined using a visual inspection tool. The density, pH, and extract weight per dose of each sample were also determined. Results Thirty-four liquid formulations (A-1-34) containing 1-9 different herbs were found. The majority of the product labels had errors in consumer age classifications. Unconventional ways of stating doses were found on two products (A-13, "tot"; A-19, cupful). Six products did not have dosing devices. No duration of treatment was indicated on 24 products. Dose errors were found on A-14 and A-22. Samples A-17 and A-28 did not have registration or batch numbers. Product A-28 did not have its herbs listed on it and was indicated for persons aged 3-8 years at a dose of 45 mL. The relative density range for the products was 0.997-1.015. From the pH investigation, no product was extremely erosive; however, 10 samples were deemed erosive (pH, 3.0-3.99), whereas 24 were minimally erosive (pH, ≥4.0). The extract weight per dose volume (20-90 mL) was 0.048-1.766 g, indicating that unit dose capsules or tablets could be formulated from the products. Conclusion The findings clearly show that Ghanaian authorities responsible for regulating herbal products must enforce guidelines for the formulation, label details, and sale of antimalarial products. Additionally, the unpleasant taste of liquid herbal mixtures can affect patient compliance and dosing convenience; therefore, it is recommended that oral solid dosage forms of herbal antimalarials are produced as alternatives to the liquid mixtures.

Ansong S, Nkrumah D, Nketia RI, Bekoe SO, Brobbey AA, Asante-Kwatia E, Komlaga G. Antimalarial Properties of Sida cordifolia L. Leaf Extract in Mice: Survivability Depends Less on Parasitaemia Suppression. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2023; 2023:5560711. [PMID: 38161788 PMCID: PMC10757657 DOI: 10.1155/2023/5560711] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/09/2022] [Revised: 05/24/2023] [Accepted: 12/14/2023] [Indexed: 01/03/2024]
Abstract
Sida cordifolia has been used to treat malaria in Ghana albeit without scientific evidence of antimalarial activity and safety. This work aimed to assess the antimalarial properties and acute toxicity of the aqueous leaf extract of S. cordifolia in murine models. Aqueous extract of the plant was analysed for both suppressive and curative antimalarial properties in chloroquine-sensitive ANKA strains of rodent Plasmodium berghei-infected mice. Acute toxicity evaluation was performed in rats according to the OECD 425 guidelines. The extract displayed antiplasmodial activity in vivo with ED50 of 117.49 ± 15.22 mg/kg and 144.84 ± 18.17 mg/kg in suppressive and curative studies, respectively. The highest % parasitaemia suppression exerted was 76.90 ± 0.64% and 61.50 ± 0.97%, respectively, in the suppressive and curative studies. Survival of infected mice treated with the extract was significantly prolonged. This was dependent on the dose of the extract but imperfectly related to the % parasitaemia suppression. Related antimalarial parameters including percentage hematocrit, changes in body weight, and temperature of experimental mice indicated alleviation of malarial symptoms of treated animals. The extract did not show toxicity in rats. Sida cordifolia L. has antimalarial properties, and was safe. It suppressed parasitaemia in both suppressive and curative studies, was not toxic to animals and prolonged the life of infected animals under treatment. This, therefore, justifies the traditional use of S. cordifolia for the treatment of malaria in Ghana.

Abstract
BACKGROUND Folk medicine is crucial to healthcare delivery in the underdeveloped countries. It is frequently used as a primary treatment option or as a complementary therapy for malaria. Malaria is a deadly disease which greatly threatens global public health, claiming incredible number of lives yearly. The study was aimed at documenting the medicinal plants used for malaria treatment in folk medicine in Kwara State, Nigeria. METHODS Ethnobotanical information was collected from selected consenting registered traditional medicine practitioners (TMPs) through oral face-to-face interviews using in-depth, semi-structured interview guide. The ethnobotanical data were analysed, and descriptive statistical methods were used to compile them. RESULTS Sixty-two indigenous medicinal plants, including 13 new plants, used for malaria treatment were identified in this study. The TMPs preferred decoction in aqueous solvent (34%) and steeping in decaffeinated soft drink (19%) for herbal preparations. Oral administration (74%) was the main route of administration, while leaves (40%) and stem barks (32%) were the most dominant plant parts used in herbal preparations. The most cited families were Fabaceae (15%) and Rutaceae (6%), while Mangifera indica (77.14%), Enantia chlorantha (65.71%), Alstonia boonei (57.14%) followed by Cymbopogon citratus (54.29%) were the most used plants. Besides, the antimalarial activities of many of the plants recorded and their isolated phytocompounds have been demonstrated. Furthermore, the conservation status of 4 identified plants were Vulnerable. CONCLUSION The study showed strong ethnobotanical knowledge shared by the TMPs in the State and provides preliminary information that could be explored for the discovery of more potent antimalarial compounds.

Habte G, Tamiru S, Eyasu K. In vivo antimalarial activity of the 80% methanolic crude fruit extract of Lagenaria siceraria (Molina) Standl. against Plasmodium berghei infected mice. Heliyon 2023; 9:e15453. [PMID: 37151678 PMCID: PMC10161574 DOI: 10.1016/j.heliyon.2023.e15453] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 03/28/2023] [Accepted: 04/10/2023] [Indexed: 05/09/2023] Open
Abstract
Background Malaria is a public health menace. Resistance to therapeutic armamentarium is impeding its control. Therefore, research targeting the discovery of novel antimalarial drug arsenals is a priority. The important point to begin the search for such drugs is the folkloric medicinal plants. Ripe fruit of Lagenaria siceraria is bored, rinsed with cold water, and one glass is used as a drink early in the morning for the treatment of malaria in Ethiopian folk medicine. In vivo antimalarial efficacy of the plant was not affirmed scientifically, though. Consequently, the present study was conducted to assess the in vivo antiplasmodial effect of Lagenaria siceraria in P. berghei infected mice. Methods The fruits were extracted using 80% methanol in water. Acute toxicity test was conducted on the extract. Secondary phytochemicals were assessed. The four day suppressive test was employed in mice infected with P. berghei. Thirty mice were grouped in to five and inoculated with P. berghei. After 3 h, three of the groups received the extract at doses 100, 200 and 400 mg/kg. The remaining groups served as negative (2% Tween80) and positive control (chloroquine). Parasitemia, packed cell volume, weight, temperature and survival time were monitored. SPSS version 22 was used for data analysis. Results No toxicity was seen in mice. The crude extract elicited significant suppression (p < 0.05) of the parasite compared to the negative control. The highest parasite suppression (77.37%) was measured at the upper dose. Furthermore, the crude extract significantly (p < 0.05) prevented body weight loss, anemia, reduction in temperature and prolonged the survival time compared to the negative control. Conclusion This study asserted that the fruit of Lagenaria siceraria is enriched with in vivo antimalarial activity. Hence, further in depth antimalarial investigations on the plant is strongly recommended.
