                        <abstract language="eng"><p>Herbal formulation has been used in recent years to treat various<br />
diseases including malaria, typhoid, dysentery, and cholera. To<br />
investigate the microbiological quality of herbal formulations.<br />
Herbal formulations were purchased from four different markets<br />
(Wadata market, Wurukum market, Modern market, and North<br />
bank market) in Makurdi metropolis. Microbiological analysis<br />
was carried out using pour plate method. Identiication of<br />
isolated microorganisms was based on their cultural,<br />
morphological, and biochemical characteristics using standard<br />
microbiological procedures. Microbiological analyses showed<br />
that the total bacterial counts (TBC) of all the test herbal samples<br />
obtained from the various markets ranged from 1.8 x103 to<br />
9.3&#215;103 cfu/ml and the total fungal count in the herbal mixture<br />
had a range of 1.0&#215;103 to 2.5&#215;103, Four bacterial species were<br />
identiied and they include; Bacillus spp, Escherichia coli,<br />
Staphylococcus aureus and Enterobacter spp. The least<br />
occurring bacterial isolate was Bacillus spp (12.5%), while the<br />
highest occurring was Staphylococcus aureus (37.5%).Four<br />
fungal isolates were identiied and they include, Aspergillus niger,<br />
Penicillium spp, Scedosporium spp, and Phialophora<br />
parasiticum. Aspergillus niger and Phialophora parasiticum<br />
were the least occurring fungal isolate (12.5%) while<br />
Scedosporium spp and Phialophora parasiticum were the most<br />
occurring fungal isolate (37.5%). Since applications of herbal<br />
medicines for curative purposes is on the increase, there is a need<br />
for risk assessment of the microbial load of the medicinal plants<br />
at critical control points during processing. Furthermore, the<br />
danger associated with the potential toxicity of herbal therapies<br />
employed over a long period of time demand that the<br />
practitioners be kept abreast of the reported incidence of renal<br />
and hepatic toxicity resulting from the ingestion of medicinal<br />
herbs.</p>

<p class="wp-block-paragraph">It is estimated that approximately80% of the population in<br>developing countries uses herbal medicine as part of their<br>primary health care. The use of herbs dates back to the time of<br>the early man, who had the crudest tools as his implements and<br>used stones to start his ire [1]. Medicinal science came into<br>Volume 2, Issue 1 2023 © 2023 Acta Traditional Medicine. All Rights Reserved.<br>Corresponding Author: Odo, J.I | E-Mail: (odojoel@gmail.com)<br>Received 01 January 2023 | Revised 20 March 2023 | Accepted 15 April 2023 | Available Online May 6 2023<br>ABSTRACT<br>existence through a Greek man called Hippocrates and as such<br>he earned his reputation as the father of medicine (Heber,<br>2008). Most savage people believed that disease was due to the<br>presence of evil spirits in the body and could be driven out only<br>by the use of poisonous and disagreeable substances calculated<br>to make the body an unpleasant place to remain. The<br>knowledge regarding the source and use of the various<br>products suitable for the purpose was usually restricted to<br>medicine men of the tribe [2].<br>Contamination of herbal medicinal products is deined as the<br>“undesired introduction of impurities of a chemical or<br>microbial nature or of foreign matter, into or onto a starting<br>material, intermediate product or inished product or inished<br>lavored product throughout production, sampling, packaging,<br>or repackaging, storage or transport”<br>The introduction of micro-organisms in herbal medicinal<br>products can alter the physicochemical characteristics of the<br>products, which may lead to harmful effects on the quality of<br>the herbal medicine products. The organisms he said were<br>Staphylococcus aureus, Escherichia coli, Rhizopus stolonifer,<br>Candida species, etc [3]. Bacteria are ubiquitous in nature,<br>therefore because of the ubiquitous nature of bacteria, they<br>contaminate almost every material, herbal juice no exception<br>[4].<br>Among the main safety risks related to medicine is<br>contamination by micro-organisms of various kinds that may<br>be adherent in leaves, stems, lowers, seeds, and roots from<br>which herbal medicines are prepared. Alternatively,<br>microorganisms can be introduced during harvesting,<br>handling, open-air drying, preserving, and manufacturing.<br>Although medicinal plants with their chemical constituents<br>carry huge applications in the treatment or prevention of<br>various diseases. The plant materials are exposed to various<br>contaminants like toxic elements, pesticides, residues, etc. but<br>the chief contaminants mainly responsible for the<br>deterioration of herbal products are the microbe. Several<br>studies showed that herbal plants are associated with broad<br>variety of microbial contaminants [5]. When herbal products<br>contaminated with these micro-organisms are consumed by<br>people, they can cause serious health issues, one of the most<br>serious issues surrounding the safety of herbal formulations<br>Odo, J.I., Acta Traditional Medicine (2023)<br>concerns regulating the level of mycotoxins found in herbal<br>preparations. Mycotoxins are a group of around 400 toxic<br>secondary metabolites produced by fungi such as Aspergillus,<br>Penicillium, Fusarium, Claviceps and Alternaria Recently [6]<br>showed that 22% of herbal plant samples studied failed to<br>comply with the quality requirement for traditional medicine.<br>Herbal medicine is most often polyherbal, being prepared from<br>mixtures of different plant parts obtained from various plant<br>species and families and may contain multiple bioactive<br>constituents that could be dificult to characterize [7]. The<br>bioactive principles in most herbal preparations are not always<br>known and there could be possibilities of interaction with each<br>other in solution. The quality as well as the safety criteria for<br>herbal drugs may be based, therefore, on a clear scientiic<br>deinition of the raw materials used for such preparations. Also,<br>herbal medicine may have multiple physiological activities and<br>could be used in the treatment of a variety of disease conditions<br>[8]. It could be administered in most disease states over a long<br>period of time without proper dosage monitoring and<br>consideration of toxic effects that might result from such<br>prolonged usage [9].<br>The usages of herbs as medicines are determined mostly by the<br>community and environment in which one grows up. [10]<br>carried out a study to determine the socio-demographic<br>characteristics and pattern of use of herbal medicines by<br>women admitted to the Obstetrics and Gynaecology<br>Department in the Komfo Anokye Teaching Hospital (KATH), a<br>teaching hospital serving the Northern part of Ghana and made<br>the following observations: More than ifty percent (50%) of<br>patients used herbal medicines which were mostly unknown to<br>the attending health workers. The less educated as well as the<br>unskilled/ semi-skilled used herbal medicines more frequently<br>compared to their more skilled and educated counterparts.<br>Herbal medicine use is thus more prevalent in the groups who<br>usually have poor socio-economic facilities and carry most of<br>the burden of social deprivation. It is possible that their disease<br>conditions may be adversely affected.<br>To achieve the desired beneit from herbal preparations, an<br>individual must take the required dose over a certain length of<br>time. Although it is generally believed that most herbal<br>preparations are safe for consumption, some herbs like most<br>biologically active substances could be toxic with undesirable<br>side effects [11].</p>

<li>© 2023 Acta Traditional Medicine. All Rights Reserved.<br>MATERIALS AND METHOD<br>Study Area<br>The study was carried out in Makurdi, Benue State. It has a<br>population of 226,198 (1991 census) with a landmass of 16km<br>radius. It has major markets like the North Bank market,<br>Wurukum market, High-level market, Modern market, and<br>Wadata market.<br>Sample Collected<br>The commercially sold herbal formulation was purchased from<br>four different markets (North bank market, Wurukum market,<br>Modern market, and Wadata market). Two samples were<br>purchased from each market and were immediately<br>transported to the Department of Microbiology laboratory of<br>the Federal University of Agriculture, Makurdi for<br>microbiological analysis.<br>PREPARATION OF CULTURE MEDIA<br>Nutrient Agar<br>This is an all-purpose medium, very rich for the support of<br>bacterial growth, 28 g of Nutrient agar was weighted and<br>dissolved in 1000 ml of de-ionized water and autoclaved, it was<br>allowed to cool before it was aseptically poured into sterile<br>Petri dishes.<br>Potato dextrose agar (PDA)<br>65g of potato dextrose agar was dissolved in 1000 ml of deionized water, the powder was allowed to dissolve and the tube<br>was plugged with cotton wool, covered with aluminum foil, and<br>autoclaved at 121C for 15 minutes. It was allowed to cool<br>aseptically and poured into a sterile plate. The surface was<br>lamed to remove air bubbles.

All Rights Reserved.<br>2.3 Sampling Method<br>Citrate Utilization Test<br>CHARACTERIZATION OF ISOLATES<br>Gram Staining<br>This is a differential staining that classiies bacteria into grampositive or negative. Thin smears of fresh, pure bacteria<br>cultures were made on clean grease free glass slides. The slides<br>were allowed to air dry and heat-ixed by passing them over a<br>Bunsen burner lame. The slides were placed on a rack over a<br>sink and looded with crystal violet for 60 seconds, the slides<br>were rinsed with clean running tap water and looded with<br>iodine for 60 seconds, the slides were rinsed with water and<br>decolorized with 95% alcohol for 30 seconds, the slides were<br>counter stain with safranin 60 seconds, they were rinsed with<br>clean running water and allowed to air dry after which they are<br>viewed under the microscope using oil immersion lens<br>(100x).Gram-positive bacteria stained purple while gramnegative bacteria stained red.<br>BIOCHEMICAL TEST FOR IDENTIFICATION OF<br>BACTERIA<br>Indole Test<br>This test is carried out to test the ability of an organism to break<br>down tryptophan, an amino acid to pyruvate and indole. The<br>test organism is inoculated into 5 ml of sterile peptone water<br>and incubated aerobically at 37C for 24 hrs. The production of<br>indole was tested by adding 0.5 ml of Kovac&#8217;sreagent to the<br>broth culture and shaken gently. A positive result shows a red<br>colour in the alcohol layer which indicates that indole was<br>produced while a negative result shows the absence of red<br>colour.<br>Catalase Test<br>The test demonstrates the presence of catalase which is an<br>enzyme that catalyzes the release of oxygen from hydrogen<br>peroxide (H2O2). A colony of 24 hours old culture was picked<br>using a sterile loop and then emulsiied in a few drops of<br>hydrogen peroxide on a clean slide. The presence of<br>effervescence indicated catalase positive reaction where as a<br>negative reaction showed no effervescence<br>Coagulase Test<br>The slide method described by [11] was used for the test. A drop<br>of normal saline was placed on each end of a slide. An 18-24<br>hours old culture of the test organism was emulsiied in each of<br>the drops to make two thick suspensions. Thereafter, a drop of<br>human plasma was added to one of the suspensions. The<br>mixture was stirred for about 5 seconds. Clumping of the<br>organism within 10 seconds is a positive test. No plasma was<br>added to the second suspension which is the control to<br>differentiate any granular appearance of the organism from<br>true coagulase clumping.<br>Urease Test<br>Isolates were inoculated into liquid urea agar supplemented<br>with urea and aseptically dispensed into sterile test tubes, and<br>slanted to solidify. They were incubated at 370C for 24-48<br>hours. The development of bright pink or red color indicates a<br>positive urea reaction [12].<br>Simmon‟s citrate agar was prepared based on the<br>manufacturer&#8217;s instruction, sterilized, poured, and allowed to<br>solidify at a slant angle of 450C. The test organism was streaked<br>on the surface of the agar slant and then incubated at 370C for<br>48 hours. A change in the color of the agar medium from green<br>to blue following the growth of the organism on the slant<br>indicated a positive test, while no color change indicated a<br>negative test.<br>Fungal Identiication<br>The fungal isolates were identiied microscopically using<br>lactophenol cotton blue test. The identiication was achieved by<br>placing a drop of the stain on the clean slide with the aid of a<br>wire loop. A small portion of mycelium from the fungal culture<br>was removed and placed in a drop of lactophenol. The<br>mycelium was spread on a slide with the aid of the wire loop. A<br>cover slip was gently applied with little pressure to eliminate<br>air bubbles. The slide was then mounted and observed with x10<br>and x40 objective lenses respectively.<br>RESULTS<br>Table 1 Presents the Morphological and bacterial counts of<br>each sample in 4 different markets in Makurdi metropolis.

This poses a great danger to human health. Since<br>herbal concoctions are prepared using varieties of medicinal<br>plants that contain active constituents that are cheap and<br>effective against common bacterial infections.<br>A number of sources of contamination of herbal preparation<br>especially during preparation have been identiied. The<br>microlora of the inal product may represent contaminants<br>from the raw materials, equipment, water, and atmosphere and<br>from personnel. Microorganisms such as Escherichia coli, and<br>Scedosporiumspp reported in this study are generally known to<br>proliferate in potable, distilled, and de-ionized water while<br>Bacillus spp, Staphylococcus, Aspergillus and penicillin are<br>commonly isolated from air. The most common source of postpreparation herbal contamination is the packaging vessels. In<br>order to enhance consumer acceptability, most herbalists in<br>Nigeria have adopted the use of bottles and plastic containers<br>as packaging vessels for their preparations. Unfortunately,<br>these vessels are not subjected to any form of sterilization after<br>washing them. Contamination of the preparation coupled with<br>the humid tropical environments may result in the proliferation<br>of microbial contaminants in the herbal remedies (WHO,<br>2007); this probably explains the high microbial counts<br>recorded in this study. Such high levels of microbial<br>contamination have been shown to result in spoilage and<br>degradation of the products or may constitute a health hazard<br>to the user [14]. Most herbal preparations are made up of<br>different components of various plant species and these<br>preparations are not standardized with respect to color, taste,<br>consistency, etc. Unlike orthodox drugs, changes in the<br>appearance, odor, taste, etc of herbal formulations due to<br>spoilage are hardly readily detected by the patients [13].<br>Among the microorganisms isolated from Herbal Medicine,<br>Bacillus, Staphylococcus, E. coli, and penicillin were the major<br>contaminants. Although the pathogenicity of these organisms<br>was not assessed, species of these agents have been<br>incriminated in serious human infections. Bacillus spp are<br>widely distributed in the soil, dust, air, and water and they are<br>resistant to environmentally destructive factors. Apart from the<br>unacceptable microbial loads observed in the samples, the<br>presence of contaminants considered to be completely<br>unacceptable in herbal preparations was demonstrated. The<br>most common isolates in the tested samples were Grampositive organisms belonging to the genera Bacillus and<br>Staphylococcus aureus are normal commensals of the<br>mammalian skin, hands, and mucous membranes. Upon<br>consideration of the extent of human contact involved in the<br>preparation of herbal medicinal samples, it is most likely that<br>sources of the contaminating Staphylococcus spp. are the<br>producers of the herbal formulations this suggests that the<br>level of hygiene of persons involved in the preparation of the<br>tested samples may be low. Similar studies carried out on<br>herbal samples include work by [15-20] have all reported that<br>the pathogens frequently isolated in herbal products were S.<br>aureus, E. coli. Except for Scedosporium which was not isolated<br>in some reports mentioned above. This work varies by<br>reporting a higher count of Bacillus spp. Contamination by<br>Bacillus spp could have arisen during growth of the herbs as the<br>bacterium is commonly found in soils. Escherichia coli, a major<br>faecal coliform may have been introduced from the water used<br>during the processing of the herbs.

<li>= Absent + = Present<br>DISCUSSION<br>Thi s s tudy has shown that there are var ieties of<br>microorganisms present in our various herbal formulations<br>which could have resulted from contaminated soils, plants and<br>its products, preparation processes, quality of water,<br>containers, and processing equipment. However, these<br>microorganisms exhibit multi-resistance to many antibiotics.<br>Since herbal formulations are mainly prepared for human<br>Odo, J.I., Acta Traditional Medicine (2023)<br>herbal mixture as shown in this study, may also be a result of the<br>plant materials, utensils used during preparation, poor hygiene<br>of the manufacturer, or even the packaging vessel after<br>processing as also suggested by many authors earlier reported.<br>Microorganisms are present everywhere and can easily<br>contaminate any substrate. Considering the packaging<br>materials, it is worthy of note that this contributes greatly to<br>microbial contamination as the inal stage of the processing is<br>the packaging. Most of the packaging cans used are not<br>sterilized and are usually picked up where they are found<br>littered along the road or in public places and barely washed<br>before being used to package inished herbal products. It was<br>observed that fungal growth was more than bacterial growth<br>and this is attributable to the low pH value of all the herbal<br>formulation samples which is favorable for fungal growth. The<br>high microbial load and presence of speciic pathogens in the<br>tested herbal formulation heave serious clinical as well as<br>pharmaceutical implications. Clinically, consumers of any of<br>these products are at risk of contracting infections by the<br>different pathogens which may be of great consequence if not<br>identiied and treated appropriately. The presence of<br>Escherichia coli in the sample indicates poor hygiene practices<br>and a lack of adequate handling of the products. According to<br>the European pharmacopoeia 2007, no Salmonella spp or<br>Escherichia coli strain should be present in samples [21]. The<br>intake of a high concentration of accumulated toxins produced<br>by organisms such as Bacillus cereus, Staphylococcus aureus,<br>and Aspergillus niger may lead to undesirable reactions in<br>consumers. [22] reported that the presence of Bacillus spp. in<br>herbal preparations is an indication that the water used in the<br>preparation of the products is not from a good source. The risk<br>is greater if the consumer is a young child with undeveloped<br>immunity, an elderly with diminished immunity, or the<br>immunocompromised patients. Incidentally, these groups of<br>consumers are the most in need of herbal medicines for the<br>treatment of many diseases to which they are susceptible</li>
