Abstract

Medicinal plants have been interested in many researchers for overcoming a catastrophic disaster of antimicrobial resistance. This study aimed to identify medicinal plants for treating UTI through an ethnobotanical survey conducted in the Biharamulo district in the Kagera region in Tanzania. Semi-structured questionnaires were used to assess the awareness of society on UTIs and their medicinal plants. UTI herbs were collected and identified. The ethnobotanical data were analyzed using the Chi-square test in SPSS version 16. Participants' awareness was justified by the statistically significant difference of p-values < 0.05. The study found most participants to have an understanding of UTI and its herbs because they identified clinical signs (85.2%), mode of transmission and etiology (41%), UTI herbs (99.5%), and used herbs to treat UTI (92.8%). Out of the 42 medicinal plants identified for treating UTI, 29 (69%) had pharmacological supports for antimicrobial activities, which were attributed to their phytochemicals and ethno medical literature support for treating UTI and other related microbial infections; they belonged to 20 families whereby the dominant were Lamiaceae 17.2 %, and legumes are (10.3 %). This agreed with other studies that society knew UTIs and their medicinal plants. Ethno medical literature supported this study. The study results were significantly justified and supported the uses of identified medicinal plants for treating UTIs with antimicrobial efficacies, as traditional healers and herbalists claimed. Hence this study may provide a direction and scope for further discovery of new UTI drugs.

Introduction

Medicinal plants possess therapeutic potentials with more significance than orthodox medications by having a wide range of efficiencies with sophisticated mechanisms for curing various illnesses. At the same time, some may become sources of nutrients, all of which enhance people's health. The holy bible depicted at most minuscule 30 medicinal plants, while Hippocrates gave over 400 herbs1. An ethnobotanical survey helps gather information about herbs from residents who belong to their traditions and beliefs2. Through an ethnobotanical survey, much-hidden information on medicinal plants can be obtained and become helpful in treating various diseases which slow down the development of the community. To effectively tackle antimicrobial illnesses, WHO associated folk and Western medicines with contemporary and alternative medications 3.

Urinary tract infection happens when microbes like bacteria and fungi colonize and infect parts of the urinary system. Previous studies showed that the prevalence of UTI is 30.9% among pregnant women at Bugando in Mwanza, Tanzania4. Bacteria and fungi cause UTIs, with E. coli being the leading microbe, accounting for more than 80% of the etiology5. The rest UTI causative agents are countered by P. mirabilis, K. pneumonia, S. aureus, E. faecalis, and fungi6. When UTI is accompanied by illnesses that deteriorate host immunity, it is regarded as a complicated UTI3. The disease is transmitted through genital organs to contact with infected agents like water from toilets and bathrooms, poor personal hygiene, the crossing of E. coli from the alimental canal to the urinary system, and sexual intercourse. Urinalysis and media-based microbial culture are the diagnostic tests for UTI7. Gave clinical indications of UTI as pains during urination, high rate of urination, fever, shivering, vomiting, and aches in the lower abdomen and back. Its side effects are associated with discomfort, deterioration of the reproductive system, body impairment, and promotes miscarriage in females. UTI is treated by using antibiotics, probiotics, and medicinal plants and equipping self and public person hygiene8.

Biharamulo district has medicinal plants found in sub-equatorial climatic conditions. Within the district civilization, there are herbalists with extensive awareness gained via battling illnesses in daily life and from oral dissemination of traditional herbal knowledge and skills from nearby nations 9. The majority of herb knowledge is passed down orally through informal education, which has resulted in the concealment of some necessary details about folk therapies among the communities and resulted into the prohibition of their accessibility of such information to the younger generation2. Herbal remedies were undermined and discredited throughout the colonial era in Africa, as inferior medical interventions, but later on, research into their phytochemicals had revealed that they possess pharmacological significance. Research is a crucial tool for taking what hearsays into consideration when putting theories into perspective in order to support what traditional healers have claimed and believed on herbal remedies for a long time2.

To address the issue, an ethnobotanical survey was required to verify the information narrated by critical informants and traditional healers regarding using specific medicinal plants to treat UTIs. Finally, to document what is revealed for society's future health and prosperity. Therefore, this study identified and established medicinal plants for treating UTI and other related microbial infections.

2.0 Materials and Methods

2.1 Description of the study area

The research was conducted in Biharamulo district in the Kagera region, which is allocated to North Western part of Tanzania. Tropical-equatorial climatic conditions with bimodal rainfall characterize the area. Peasant agriculture is the economic backbone of society. Its dominant tribes are Subi, Ha, and Haya, who belong to Christians, Muslims, and paganism5 . Five of the 17 wards, namely Biharamulo town, Kabindi, Kalenge, Nyarubungo, and Nyakahura wards, were selected for the study. Below is a map of the Biharamulo district indicating the study areaFigure 1 .

2.2 Study designs

It employed a cross-sectional study design. The cross-sectional study design involved interviewing ethnobotanical surveys among five wards of Biharamulo district.

2.3 Sample Size and sampling techniques

Snowball sampling technique was used to recruit 400 participants in an interview by using semi-structured questionnaires during an ethnobotanical survey in Biharamulo district; it involved five wards, namely Biharamulo town, Kabindi, Kalenge, Nyarubungo, and Nyakahura. According to sample size was calculated from Yamane's formula: -

n=N/ (1+Ne2)

n=124 368/ (1+124 368*0.052)

Where n = desired sample size, e= acceptable error (5%), N =124 368 people as the known population from the census 2012 in 5 wards of Biharamulo district. Therefore, the sample size was 399 participants.

2.4 Ethnobotanical Survey and Identification of medicinal plants

In the ethnobotanical survey, villagers, traditional healers, and key informants in 5 wards of Biharamulo district were interviewed using semi-structured questionnaires with open and closed-ended questions. Information on medicinal plants vernacular names or morphology helped to identify the plants by matching their pictures with those in plant net identification software and confirmed through the literature10 .

2.5 Method of data analysis

The ethnobotanical survey data were compiled by using Microsoft Excel in Windows 2016. Version 16 of the Statistical Package for Social Sciences (SPSS) software was used to analyze the data using the Chi-square test11 . Statistically significant differences between interviews' awareness of UTIs and their medicinal plants were determined from the Chi-square test at the p-values < 0.05.

3.9 Information dissemination on UTI and its medicinal plants in Baramulo's societies

Information dissemination on UTI and its medicinal plants among Biharamulo societies was distributed by villagers among themselves (49.5%), followed by medical experts and public health extension educators (18.8%), parents (11.8%), traditional healers (5.5%), from other occupations (2.3%) and lastly, those who did not remember where they acquired UTI information (0.8%). These indicated a need for further provision of UTI information by responsible institutions, as most of the education was provided by villages that were less knowledgeable about UTI Figure 2

3.1 Medicinal plants and their information

Based on interview information in the ethnobotanical survey, among the 42 medicinal plants identified, only 29 (69%) were supported by literature to have pharmacological significance in treating UTIs. Furthermore, their vernacular and botanical names, families, parts, usable states, preparation methods, and diseases treated were documented, whereby among the active 29 herbs, pharmacologically treated UTI (96.5%), typhoid (48.3%), malaria (34.5%), anthelmintic (24.1%), STDs (20.9%), cough (17.2%), worm infections (11.9%), wounds and ulcers (17.2%), fungal infections (13.7%), anemia (10.3%), diabetes, cancer, and toothache were each represented by cancer (6.9%), measles, cardiovascular diseases, and yellow fever were each represented once by (3.4%) (Table 2.9).

The 29 medicinal plants belonged to 20 families, whereby the dominant were Lamiaceae (17.24%), Asteraceae, Rutaceae, and Myrtaceae each accounted (6.9%), while the rest appeared once as 3.45%Table 9

4.0 Discussion

This study revealed that society must be aware of UTI, their medicinal plants, and other microbiological infections like typhoid, gonorrhea, and syphilis. In sex, females were more knowledgeable about UTI and its medicinal plants compared to males, it was attributed to the fact that women have genital anatomical structures that expose them to susceptibility to UTI infections compared to males, and they also maintain the health status of their families. Support for the same argument came from and who realized that women had the primary responsibility of providing healthcare in a family. This circumstance sparked their interest in researching accessible and effective medicinal plants against nosocomial infections, including UTIs.

The age groups were associated with acquiring knowledge of UTI medicinal plants. The Old age group was more knowledgeable, followed by the middle and finally, the youth age. This was linked to older people's prolonged exposure to herbs against ailments, especially traditional healers, who acquire herbal knowledge and experiences throughout their lifetime. Gave a similar finding that the level of understanding of herbs and experiences in a community varies directly in proportion to seniority, provided that senescence had not deteriorated the mental activities. The same ideal was observed by who argued that youths' irritation with medicinal plants was associated with seniors' concealment in herbs and youth preferences for orthodox over herbal remedies.

Biharamulo town wards were more knowledgeable in UTI and its medicinal plants due to extensive connection with individuals who brought their ancestral herbal knowledge from rural to urban areas, as opposed to other rural wards with few tribes fixed to a limited number of herbs. The previous studies from Lagos and proved that about 66% of urban inhabitants recognized and used medicinal plants for contagious infectious ailments like UTIs at affordable expenses.

Participants with higher educational levels had more heightened awareness of UTI but were less knowledgeable in its medicinal plants as most used antibiotics and ignored medicinal plants. Vice versa was accurate at the informal and primary levels, where most of them were aware of medicinal plants compared to higher levels of education [Table 6]. Similar findings from indicated a negative relationship between attained education and knowledge of folk medicine, with the argument being that as education levels ri, it initiates the loss of interest in folk medicine. They supported the argument by providing evidence that the uneducated exemplified more herbs than scholars.

Compared to other professions, traditional healers had a better understanding of UTI and its medicinal plants as they treated many patients and marketed herbs as commodities, giving them much experience with antimicrobial plants.

Hangaza tribes were more aware of medicinal plants for treating UTI than other tribes due to their proximity to neighboring nations like Burundi and Rwanda, which have historically swapped information about herbs dating back to the colonial era.In addition, people could participate by disclosing the details of UTI medicinal plants. This could account for Haya, who were suspected of knowing many medicinal plants but mentioned a small number of UTI medicinal plants. According to popular belief, healers keep secret in disseminating herbal information.

As a result of their accessibility and commitment to plant protection, most participants from Biharamulo applied leaf decoctions and infusions as preparation methods for UTI treatments. This scenario was in line with a previous study conducted by who credited for the accessibility and consistency of leaves throughout the year except for a few arid climate zones. Furthermore, appreciated people from Kagera for utilizing leaves in medicinal plants.

Information dissemination on UTI and its medicinal plants within Biharamulo's societies was enhanced by less than 50% among villagers. Public health extension educators, traditional healers, and parents have educated the community on UTIs to a small extent, which is why most respondents did not understand the causes and transmission of UTIs. Comparative research from Kenya by shows that non-traditional healers, particularly older women are the best sources of herbal information for over 50%, while traditional healers hinder the herbal details. These signified a need for further provision of UTI information to the majority where villages provide UTI education. Regarding African folk medicine innovation has been hampered by the absence of reliable and secure supervision, inconsistent dosage, toxicity assessment, and recordkeeping. Herbalists are urged to adhere to these restrictions.

Biomedical justification for UTI herbal efficiencies. The literature review confirmed that all 42 medicinal plants possess tannins, phenols, and flavonoids with different extinctions of phytochemicals as described below; It has been ascertained that the Combretaceae family, which includes Terminalia mollis, contains resins and combrela tannins that kill microorganisms by precipitating their amino acids in cell walls. Myrtaceae (S. guineense, and S. cordatum) reported that anticancer have antimicrobial, hypoglycaemic, anthelmintic, and virucidal activities [46]. On the other hand, it was contended that members of the Olacaceae family, notably X. caffra, had antimicrobial, anticarcinogenic, and antiparasitic properties. Inulin found in the Asteraceae was reported by to have antimicrobial properties, including UTI. Many plants in the Lamiaceae family, but some of them, like S. hispanica, P. barbatus, and H. opposite, had poor antibacterial activity reported in the literature.

According to rutaceae family (C. limon and Z. album) contain limonoids, carbazole, benzylisoquinolines, and anthranilate, all of which have antimicrobial, antitumour, and anti-HIV. Kleinia sp had oleanolic acid, which accounts for antimicrobial activities. Family Solanaceae (P. peruviana) was reported by to comprise solanine, solasonine, and solamargine, which enhances antibacterial, anticancer, and cardiac impairments. Family Lauraceae (C. verum) contains aroma, Benzylisoquinoline, cinnamaldehyde, benzyl benzoate, and terpenoids, which elicit antimicrobial activities, antidiabetic and antiulcer potentials. Iridoids, quinones, and phenylpropanoids were reported by in Bignoniaceae (J. mimosifolia) to be accountable for the antibacterial, antiprotozoal, antidiabetic, and antitumor. Aloe vera contains anthraquinones and phenols responsible for antibacterial and antiplasmodial actions. Azadirachta indica was reported by to consist of limonoids, phenols, terpenoids, and coumarins, used as antimicrobial, antiplasmodial, and antiulcer.

Jatropha curcas produced atropine, terpenoids, and curcumin, which were associated with antibacterial, anti-HIV, relieve toothache, wound, and tumor healing properties. Lantana camara yields verbascoside and lantadene had antimicrobial activities. Moringa oleifera contains Benzyl glycosylates and gallic acid, which signifies antimicrobial, anticancer, antihyperglycemic, anti-infertility, and modulating the immune system. Clematis terniflora contains clematichinenoside, benzylisoquinolines, and triterpenoid, which are antibacterial, antiplasmodial, and antitumor and facilitate programmed cell death. Cymbopogon citratus was investigated by and found that it possesses scent citral and limonene, which are utilized as anticarcinogenic and can potentially kill bacteria and reported the family Leguminosae (E. Abyssinia, S. siamea, and S. didymobotrya possess resins, quinolizidine, anthraquinones, sennosides, naphthalene, and naphthalene with pharmacological significance in helminth and microbial infections.

According to the previous study, Harungana madagascariensis (Hypericaceae) produces the anthraquinones hypericin, hyperoside, and harungin used to treat diabetes, ulcers, and typhoid. Ipomoea America (Convolvulaceae) has phenylpropanoid, glycolysis, convolving, cyanogenic glycoside, and phytate, used as antimicrobial, antidiabetic, treats high blood pressure, and antitumor. Neocarya macrophyla, which incorporates terpenes and stigmasterol, was reported to be vital for antimicrobial and skin infections. Cucurbitacin and phytosterols from Zehneria scabra are used to fight against cancer and microbiological diseases. Finally, phytochemical analysis conducted by revealed the synthesis of gingerol isomers and zingiberene in Zingiber officinale, both of which have antibacterial and antifungal potentialities. Other species and their antimicrobial activities in different families are indicated in (Table 9). The 29 medicinal plants (69%) identified out of the total 42 were found to have related therapeutically implications, ethnobotanical assertions, pharmacological justifications in literature, or possessed potential phytochemicals enough to treat UTI or related microbial illnesses.

5.0 Conclusion

This study succeeded in documenting UTI medicinal plants used in Biharamulo district rather than oral herb information dissemination as practiced by indigenous people. Phytochemical screening and sensitivity tests in the literature revealed that medicinal plants well known and mentioned at high frequencies from the ethnobotanical survey had little active phytochemicals, which accounted for weak antimicrobial activities compared to those mentioned by few people at low frequencies; this indicated that few people know vibrant UTI medicinal plants due to secrecy of traditional healers and this study will disseminate efficacies of the selected UTI medicinal plants.

This study justified the claims of traditional healers and herbalists on the uses of identified selected medicinal plants to have efficacies against UTI microbes and other related microbial infections. Therefore, the present study provided a direction, evidence, and scope for further discovering new UTI drugs for combating antimicrobial resistance.

6.0 Recommendations

Further research should be conducted to evaluate the antimicrobial effectiveness of identified medicinal plants and ensure their safety to users. Social and public health officers should educate people unaware of UTIs and their medicinal plants. Due to their pharmacological activities, society is advised to use environmentally friendly utilization of the herbs to sustain them so that they become reliable for the next generation.
