Spices and herbs are widely used food ingredients that enhance most organoleptic features of prepared foods. They are also used for medicinal and preservative purposes. Spices and herbs are potential carriers of bacteria, yeasts, and molds due to the nature of cultivation, harvest methods, storage conditions, packaging procedures, distribution, sale, and general handling. Although some fungi have been identified to be associated with most spices and herbs elsewhere in the world, little has been done on the presence of fungi in spices and herbs in Ghana. This study sought to identify the toxicogenic fungal profiles, mycotoxins (aflatoxins) present in some herbs, bay leaf (Laurus nobilis) and garden egg leaves (“gboma”) (Solanum macrocarpon), and spices, ginger (Zingiber officinale) and “dawadawa”(Parkia biglobosa), as well as to investigate the antimicrobial properties of the selected herbs and spices. The decimal reduction technique was used to plate onto Dichloran Rose Bengal Chloramphenicol (DRBC) agar media plates for fungal growth. Aflatoxin detection was carried out with high-performance liquid chromatographer connected to a fluorescence detector (HPLC-FLD). Antimicrobial properties were carried out using the agar diffusion method on solidified, freshly prepared Mueller-Hinton agar. A total of 12 species belonging to 7 genera, Aspergillus (niger, flavus, fumigatus, and ochraceus), Fusarium (oxysporum, verticillioides), Mucor (racemosus), Penicillium (digitatum, expansum), Rhizopus (stolonifer), Rhodotorula sp., and Trichoderma harzianum, were identified as fungal contaminants. Fusarium oxysporum was the most predominant species identified. Fresh ginger recorded the greatest number of colony-forming units (3.71 log10 CFU/g) with bay leaves recording the least number of colony counts (2.36 log10 CFU/g). Mycotoxin concentration detected in gboma was and in dawadawa was ; however, mycotoxins were not detected in bay leaf and ginger. Ginger exhibited antibacterial activity against all bacteria ranging from to zones of inhibition. Ginger, bay leaf, and gboma extracts displayed fair antimicrobial activity against the bacteria investigated. On the other hand, dawadawa generally produced the least resistance against the five bacterial species but exhibited the highest zone of inhibition. All samples were slightly acidic with pH readings ranging from 5.81 to 6.76.

The Kumasi Central Market is the largest urban open market in Ghana and animals used for medicinal purposes are among the items that are typically displayed for sale. However, no study has been undertaken on the animal species sold for traditional medicine purposes. This study took inventory of animal species traded for medicinal purposes in the Kumasi Central Market and examined their conservation implications. The species recorded to be traded comprised 5 taxonomic classes, belonging to 20 families. Chameleons were found to be the most traded animal species. Seven (23%) of the species traded were found to be threatened under IUCN Red List, with four (13%) species listed on Appendix I of CITES, and eight (26%) species on Schedule I of Wildlife Conservation Regulations of Ghana. Wildlife regulations are not serving as a deterrent to the trade in threatened animal species. There is a need to sensitize traders about the threats faced by these animal species and provide explanations as to why these species should be protected.

The incidence of liver diseases is increasing globally, and many patients in developing countries are resorting to the use of herbal products as treatment. This study was aimed at establishing the safety and effectiveness outcomes for patients with deranged liver panel treated with a Ghanaian finished polyherbal product. The product Heptonica is prepared by CPMR from three medicinal plants: Bidens pilosa, Citrus aurantifolia, and Trema orientalis. Fifty (50) participants with clinical and biochemical signs of liver impairment were purposively recruited and treated for a period of 28 days. Participants received Heptonica at a dose of 30 mL 8 hourly after meals for the treatment period. Clinical and biochemical evaluation (liver panel test, renal function test, haematology, and urinalysis) of subjects for the safety and effectiveness of the product was undertaken at days 0 (baseline), 14, and 28. Compared to the baseline values, Heptonica did not have any untoward effect on renal function, haematological parameters, and urine parameters of subjects. Clinical and liver panel results of the participants also improved compared to the baseline: serum aspartate transaminase (AST) (p < 0.0001), alanine transaminase (ALT) (p < 0.0001), gamma‐glutamyltransferase (GGT) (p‐ 0.0013), total bilirubin (p‐0.0136), direct bilirubin (p < 0.0001), total proteins (p‐0.0409), and alkaline phosphates (p‐ 0.0284). Level of albumin showed no significant difference within the study period. The outcome of this study indicates Heptonica has hepatorestorative action with no observable toxicity and can be used with confidence as indicated as a liver tonic.

Certain medicinal products, like pain medications and stress-reducing drugs, with therapeutic benefits but psychoactive side effects, may be misused, especially among medical personnel. This study used a phenomenological study design. A semi-structured interview guide was used to collect data from respondents. The data gathered were transcribed verbatim, reviewed thoroughly by the researchers, and analyzed. The study presents evidence on healthcare workers’ drug misuse, including withdrawal challenges, life impacts, and coping strategies. It emphasizes professional help, diversional therapy, boundaries, and support. It highlights the challenges of seeking assistance and calls for comprehensive efforts, recommending policies in healthcare organizations to address this issue. Based on the study’s findings, a specialized training program to detect substance misuse, a dedicated hotline for reporting difficulties, as well as providing assistance and services for healthcare staff struggling with drug misuse are all recommended.

There is an upsurge in the incidence of persons living with infectious diseases and their associated symptoms. Also, there is increased resistance and high cost of available synthetic antimicrobial therapeutic agents. This calls for screening candidate herbal products to examine the risk-to-benefit ratio for users. Moreover, there are inadequate proven scientific studies to assess the quality, effectiveness, and toxicity of herbal products that traditional medicine practitioners in Ghana commonly use for the management of infectious diseases such as those caused by Neisseria gonorrhoeae, Candida albicans and the symptomatic management of symptoms associated with infections like cough, skin infections among others and gastritis. Kantinka BA and Kantinka Herbaltics, two multicomponent herbal products, have been used to manage the above-mentioned disease conditions. The study aims to evaluate the in vitro antibacterial activity, assess the retrospective clinical effectiveness (clinical responses; the disappearance of presenting signs and symptoms associated with infections, gastritis), and the quality and toxicity of Kantinka BA and Kantinka Herbaltics. The products are registered by the Food and Drugs Authority (FDA). Data on 200 patients who were diagnosed with infectious diseases such as Human Immunodeficiency Virus (HIV) / Acquired Immunodeficiency Syndrome (AIDS) and associated symptoms from January 2018 to June 2018 was obtained from the Adom Herbal Clinic, and the Tafo Government Herbal Medicine Records Unit was assessed. The antibacterial activity of the products was evaluated using the HT-SPOTi method. Phytochemical screening, microbial load, and pH were carried out according to standard procedures. Acute toxicity was carried out according to the Organization for Economic Cooperation and Development (OECD) guideline 425. Phytochemical screening, pH, and microbial load have been established for both products. Binding toxicity studies revealed that the products are non-toxic at a 2000 mg/kg dose. The two products exhibited antimicrobial activities against the test organisms with Minimum Inhibitory Concentration (MIC) and Minimum Lethal Concentration (MLC) determined for Kantinka BA and Kantinka Herbaltics as 5% and 10% and <80, respectively, against C. albicans and N. gonorrhoeae - the signs and symptoms associated with infections disappeared during the management period. The products are safe and may effectively manage some infectious diseases and associated symptoms.
