Medicinal plants used by traditional medicine practitioners in treatment of alcohol-related disorders in Bushenyi District, southwestern Uganda

Background: Alcohol-related disorders rank seventh among risk factors for morbidity and mortality globally, posing a significant public health burden. In Africa, including Uganda, there is limited availability and utilization of pharmacotherapies to treat alcohol-related disorders. This study documented medicinal plant species, plant parts used, and the methods of preparation and administration utilized by Traditional Medicine Practitioners (TMPs) in treating alcohol-related disorders in southwestern Uganda.

Methods: A descriptive cross-sectional ethnopharmacological survey was conducted among TMPs within Bushenyi District, southwestern Uganda. Data was collected with key informant interviews using semi-structured questionnaires. The TMPs identified medicinal plants by local names. Plant specimens were collected and deposited at the Department of Biology, Faculty of Science, Mbarara University for identification and voucher numbers allocated. The plant scientific names and species were identified based on the International Plant Names Index. Plant species, family, life form, number of mentions, method of collection, preparation and administration were analyzed using descriptive statistics in Microsoft Excel. The survey data were utilized to compute Frequency of Citation, Relative Frequency of Citation, and Informant Consensus Factor.

Results: We enrolled 50 traditional medicine practitioners aged between 34 and 98 years, with a mean age of 67. Approximately two-thirds were female (66%, 33/50), and mean experience in traditional healing was 31 years. The total number of plants identified were 25 belonging to 20 families. The most prevalent plant life form was herbs (36%) while grasses (4%), were the least. Leaves (48%) were the most utilized plant parts with the least utilized being the barks. The most prevalent method, adopted by approximately one-third of the TMPs, involved drying the plant material in the sun. The Informant Consensus Factor was 0.67.

Conclusion: The study shows that the traditional medicine practitioners in Bushenyi district use a wide diversity of plants species to treat alcohol related disorders. The relatively high Informant Consensus Factor suggests a significant level of agreement among TMPs regarding the use of the identified plants. We recommend further investigations into phytochemistry, safety, efficacy, and mechanisms of action of the identified plants.

Background

Globally, about 2.3 billion people are current drinkers of alcohol, and this is linked to immediate and long-term harmful effects on health and social and economic wellbeing (WHO, 2019a). Alcohol has a detrimental influence on 13 out of the 17 Sustainable Development Goals (SDGs), thus hindering progress towards health-related targets (Collin and Casswell, 2016). Alcohol abuse is directly linked to over 200 diseases and health conditions, including liver disorders, road traffic accidents, violence, cancer, cardiovascular diseases, mental disorders, suicides, tuberculosis, and HIV/AIDS (Bardach et al., 2019; Im et al., 2023). In 2016, alcohol misuse was globally ranked as the seventh leading risk factor of morbidity and mortality and was responsible for 5.1% of all Disability-Adjusted Life Years and 7.2% of all premature deaths (Griswold et al., 2018; WHO, 2019a). In the African region, harmful alcohol consumption contributes to 6.4% of all deaths and 4.7% of Disability Adjusted Life Years (Ferreira-Borges et al., 2016). Uganda is ranked among the highest consumers of alcohol in Africa, with a reported per capita consumption of 9.5 L, significantly surpassing the 6.3 L for the African region (WHO, 2019b). Furthermore, 28.8% of adult Ugandans aged 18 years and above are current alcohol drinkers, and 9.8% have an alcohol-related disorder (Kabwama et al., 2016). A high burden of alcohol has been demonstrated in studies in southwestern Uganda where it has been associated with risk of HIV infection and its treatment outcomes (Santos et al., 2014), intimate partner violence (Ohurira et al., 2023), risky behaviors (Bajunirwe et al., 2013; Nabifo et al., 2021), risk of mental illness (Bajunirwe et al., 2014) and injuries (Diamond et al., 2018).

While harmful alcohol consumption remains a significant public health concern, there is a limited availability and utilization of pharmacotherapies to complement psycho-social interventions (Carpenter et al., 2018). The three frequently employed pharmacotherapies (disulfiram, acamprosate, and naltrexone) for the treatment of alcohol-related disorders are of limited availability in resource-constrained settings and are associated with severe side effects the more serious ones being hepatotoxicity, renal impairment and peripheral neuropathy (Skinner et al., 2014). Exploring complementary and alternative pharmacotherapies such as herbal medicines with less side effects, and potential significant medical, social, and economic benefits, is therefore a viable option requiring research focus. The utilization of plant-based remedies for the treatment of alcohol-related disorders is documented in the literature (Singh et al., 2020). For example, traditional medicine approaches in the treatment of alcohol-related disorders using plants derivatives have been described by Xu et al. (2005), Lu et al. (2009) and Liu et al. (2011) in China, as well as by Corkery (2018a) in West Africa. Examples of medicinal plants studied internationally for the prevention and treatment of harmful alcohol drinking include Kudzu (Pueraria montana (Thunb.) Merr.) (Lukas et al., 2005; Lukas et al., 2013), St. John’s wort (Hypericum perforatum L.) (Rezvani et al., 1999), ginseng (Panax ginseng C. A. Mey.) (Carai et al., 2000; Lee et al., 2014), Iboga (Tabernanthe iboga Baill.) (Corkery, 2018b; Falkenhaug, 2023), Indian winter cherry (Withania somnifera (L.) Dunal) (Bansal and Banerjee, 2016) and milk thistle (Silybum marianum (L.) Gaertn.) (Tomczyk et al., 2012; Singh et al., 2020).

African traditional medicine (ATM) is defined by the World Health Organization as ‘the total knowledge, skills and practices based on the theories, beliefs, and indigenous cultural experiences, whether explicable or not, used in the maintenance of health, and diagnosing, preventing, or eliminating physical, mental or social diseases’ (WHO, 2013a). Herbal medicine, a major component of ATM, encompasses herbs, herbal materials, herbal preparations, and finished herbal products. These may consist of entire plants, plant parts such as leaves, bark, berries, flowers, and roots, and/or their extracts prepared with the intention for human therapeutic use or for other benefits in humans (WHO, 2001). African traditional medicine plays a significant role towards universal health coverage among people in sub-Saharan Africa, especially in rural areas where 60% of the population reside. ATM is often favored over modern medicine due to its cultural acceptance, affordability and accessibility, and also because the Traditional Medicine Practitioners are integral members of local communities.

According to the World Health Organization, the practitioner-to-population ratio for traditional medicine in Uganda stands at approximately 1:200–400. In comparison, there is just one Western-trained doctor for every 18,000 people (WHO, 2013b). This underscores the substantial contribution of traditional medicine to the country’s healthcare human resources. An estimated 200,000 TMPs exist in Uganda, serving a substantial portion of the population (Degonda and Scheidegger, 2012). It is further reported that 60%–79% of the Ugandan population turn to traditional medicine to meet their healthcare needs, including but not limited to diseases or conditions such as malaria, HIV, digestive and respiratory problems, toothaches, skin diseases, and childbirth complications, diabetes, snakebites and hypertension (Tugume et al., 2016; Opio et al., 2018; De, 2019; Gumisiriza et al., 2019; Asiimwe et al., 2021; Akwongo et al., 2022). While alcohol-related problems constitute a significant health concern in Uganda, the utilization of pharmacological treatments for its management remains limited. Research and anecdotal evidence suggest that TMPs in Uganda employ herbal remedies for addressing alcohol-related disorders (Maling et al., 2023). The objective of this study was to document the medicinal plant species, plant parts employed, and the methods of preparation and administration utilized by the TMPs in the treatment of alcohol-related disorders in the southwestern region of Uganda. The study also aimed at determining the level of agreement among Traditional Medicine Practitioners regarding the utilization of medicinal plants for treating alcohol-related disorders in southwestern Uganda.

Methods

Study area

A cross-sectional ethnopharmacological survey was conducted in rural communities within Bushenyi District, located in southwestern Uganda (Figure 1 below). Data collection took place during the months of July and August 2020. Bushenyi District, located approximately 320 km southwest of the capital city Kampala, has a population of 246,100 people (UBOS, 2014), with the majority (73.8%) residing in rural areas. Geographically, the district lies at coordinates 0.4871° S and 30.2051° E, featuring low-lying plateaus intermingled with hilly terrain and receiving an annual rainfall of 1,500–2,000 mm. The area is adorned with tropical rainforests such as Kalinzu, Katsyoha-Kitomi, and Imaramagambo, that together cover 84 square kilometers (Bushenyi District Local Government, 2014), along with savannah woodlands and wetland vegetation. In addition, the district has fertile loamy soils with varying proportions of sand and clay. Most of the district’s population (87%) is engaged in subsistence agriculture, but are also involved in commercial tea, coffee and bananas cultivation. Other economic activities include fishing, stone quarrying, sand and mineral mining, tourism and lumbering. The main ethnic groups in the district are the Banyankole, who are the majority, along with the Bakiga and Baganda. The main local language spoken is Runyanore-Rukiga. We chose Bushenyi district as our study area due to the presence of an organized group of traditional healers, the Bushenyi Medical and Traditional Healers Association (BUMETHA). Founded in 1988, BUMETHA actively fosters collaboration between modern and traditional medicine, including in research, some of which has been published (Tumwesigye, 1996; Catherine et al., 2020; Primah, 2023).

Study participants

We recruited traditional medicine practitioners with experience in treating patients with alcohol drinking problems using medicinal plants and residing within the study area. To be included in the study, the traditional medicine practitioner had to be a resident in the study area and have experience in managing alcohol related problems using medicinal plants. The traditional medicine practitioners who were unwilling to share the plants they used were excluded from the study.

Sample size and sampling

A sample size of 50 TMPs was determined based on a precedent from a similar study conducted in Uganda (Ssenku et al., 2022) as well as sample size estimation techniques for qualitative studies described by Morse (Morse, 2015). In this guide by Morse, a sample size of 30–60 for qualitative ethnographic studies is recommended. We therefore estimated our sample size a priori at 50 basing on this guide and a similar study done in Uganda. We purposively selected the TMPs who treat alcohol disorders using the snowball technique (Parker et al., 2019). The process commenced with the chairman of their association, who provided the initial contacts.

Data collection process

Data was collected using key informant interview technique and semi-structured interview guide and questionnaire developed by the research team. The interview guide collected data on socio-demographic characteristics, physical address of traditional medicine practitioner, plant identification using local names, plant parts used and collection, methods of preparation and administration.

The key informant interviews were conducted by three research assistants all conversant with the local culture and fluent in the local language (Runyankore-Rukiga) as well as English. All the three research assistants had experience of working with traditional healers in research and collaboration projects in southwestern Uganda. In addition, they had a health background, two in nursing and mental health and the other in public health. Details of the questionnaire and interview guide are shown in Table 1 below.

Table 1

Table 1. Questionnaire and interview guide.

Plant identification

The research team and the traditional medicine practitioners made field trips to where the plants grew. The traditional medicine practitioners identified the medicinal plants they use to treat alcohol by local names. Voucher specimens of the plants mentioned by the TMPs were then collected using a procedure described by Martins and others (Martin, 2010) and taken to a botanist at the Department of Biology, Faculty of Science, Mbarara University of Science and Technology where voucher numbers were assigned. The scientific names of the plants and species were identified based on the International Plant Names Index (Ipni, 2012). The voucher specimens were preserved at the Department of Biology of Faculty of Science, Mbarara University.

Quantitative ethnobotany

Data obtained from the survey were used to calculate the following ethnobotanical indices: Frequency of Citation (FC) (Tardío and Pardo-de-Santayana, 2008; Faruque et al., 2018), Relative Frequency of Citation (RFC) (Tardío and Pardo-de-Santayana, 2008; Faruque et al., 2018) and the Informant Consensus Factor (ICF) (Tardío and Pardo-de-Santayana, 2008; Faruque et al., 2018). The indices were calculated as follows (Faruque et al., 2018):

Frequency of Citation (FC)

$\text{FC}=\frac{\left(\text{Number}\text{of}\text{mentions}\text{of}\mathrm{a}\text{particular}\text{plant}\text{species}\right)}{\left(\text{Total}\text{number}\text{of}\text{mentions}\text{of}\text{all}\text{species}\right)}\times 100$

Relative Frequency of Citation (RFC)

$\text{The\hspace{0.17em}RFC}=\frac{\text{Number}\text{of}\text{informants}\text{who}\text{mentioned}\text{each}\text{plant}\text{species}}{\text{Total}\text{number}\text{of}\text{informants}\text{in}\text{the}\text{study}}$

The RFC index ranged from “0” when nobody referred to a plant as useful to “1” when all informants referred to a plant as useful.

The informant consensus factor

The Informant Consensus Factor (ICF) is a measure used in ethnopharmacological studies to quantify the level of agreement among traditional medicine practitioners regarding the use of specific plants for a particular ailment category, which is alcohol in this study. The ICF was calculated in this study using the formula (Oryema et al., 2021): ICF = $\left({\mathrm{N}}_{\text{ur}}{-\mathrm{N}}_{\mathrm{t}}{\left)/(\mathrm{N}\right.}_{\text{ur}}-1\right)$ where N_ur is the number of use reports or mentions and N_t is the number of species used.

Data analysis

Plant species, family, life form, number of mentions by TMPs, method of collection, preparation and administration, Frequency of mention and Relative Frequency of mention were analyzed using simple descriptive statistics in Microsoft Excel 2019 (Frye, 2018) and summarized in frequency tables and figures.

Ethical considerations

All study participants provided individual written informed consent. For those participants who lacked formal education or could not read and write, the consent form was read aloud to them verbatim, and they expressed their consent by providing a thumbprint. Throughout the research process, the research team maintained a respectful and considerate relationship with local communities and authorities. Additionally, the team took precautions to ensure that the locations from which the plants were collected held no spiritual significance that could potentially conflict with the research objectives. Plant samples were meticulously collected with a strong focus on conservation, making every effort to avoid depletion of plant populations. In the case of cultivated plants, specific permission was obtained prior to collection. The research was reviewed and approved by the Mbarara University Research Ethics Committee (#39/02-20).

Results

Sociodemographic characteristics of the traditional medicine practitioners

Fifty traditional medicine practitioners were enrolled into the study. The ages of the TMPs ranged from 34 to 98 years, with a mean age of 67. The 25th percentile age was 59 years, indicating that three-quarters of the traditional healers were older than 59 years. The mean experience of the TMPs was 31 years, while the 50th percentile years of experience in traditional healing was 30, indicating that half of the healers had more than 30 years of experience in traditional healing. Approximately two-thirds of the TMPs (33/50, 66%) were female. The majority of participants (42/50, 84%) had either not received formal education or had completed only primary education. Nearly all (46/50, 92%) were engaged in additional occupations alongside their traditional medicine practices, primarily in peasant farming and informal businesses. Only four of the participants exclusively practised traditional medicine without any other occupation. Details of the socio-demographic characteristics are in Table 2 below.

Methods used to prepare and administer plant materials

Among the 50 Traditional Medicine Practitioners interviewed, 40% exclusively utilized a single plant, 38% combined two plants, and 19% mixed three or four plants in the preparation of herbal remedies for alcohol. The traditional healers utilized four methods to prepare the medicinal plant remedies. The decoction method involved the prolonged boiling of plant parts, such as roots, bark, or seeds, in water to extract medicinal compounds. Tinctures were made by immersing plant parts in alcohol or a mixture of alcohol and water. Additionally, plant materials were dried and processed into powders for application. Finally, certain healers employed the technique of pounding or squeezing fresh plant parts to extract beneficial juices. The most prevalent techniques employed by the Traditional Medicine Practitioners for preparing medicinal plant remedies were squeezing or pounding plant parts to extract juice, utilized by 41% of the healers, and the least was tincturing used by only 8% of the healers. In terms of administering the powder or juice, all the TMPs, with the exception of one, mixed 1–2 spoonfuls of the powder or juice with alcohol, which was then given to the patient for consumption. The sole exception to this practice involved a TMP who combined the powder with a ripe banana, forming a paste that was given to the patient for ingestion. Figure 5 below shows the methods used by the healers in the preparation of the medicinal plant parts.

Figure 5

Figure 5. Methods used by traditional medicine practitioners to prepare medicinal plants treating alcohol-related disorders.

Quantitative ethnobotany

In this survey, the Relative Frequency of Citation (RFC) ranged between 0.02 and 0.44. Based on this RFC data, the four most commonly used ethnomedicinal plant species were D. fragrans (0.44), C. canephora (0.40), S. officinarum (0.1) and M. scandens (0.06).

We calculated the Informant Consensus Factor (ICF) using the following formula: ICF = (N_ur - N_t)/(N_ur −1) where N_ur is the number of use reports or mentions and N_t is the number of species used. In this study, N_ur was 74, and N_t was 25. Therefore ICF = $\left(74–25\right)/\left(74-1\right)$ = 0.67

Discussion

Ethnopharmacological surveys play a crucial role in enabling scientists to identify plants with potential medicinal properties, that can be further integrated into healthcare and support healthcare provision. In this study, we undertook an ethnobotanical survey to document both the plants as well as associated practices employed by TMPs for treating alcohol-related disorders in Bushenyi District, southwestern Uganda.

Participant characteristics

The observation in this study that the majority of TMPs were women, and predominantly older, aligns with findings in various regions of Uganda (Akwongo et al., 2022; Ssenku et al., 2022). However, it is divergent from other studies that reported a predominant male presence (Mongalo and Raletsena, 2022; Tabuti et al., 2023). The higher representation of female traditional medicine practitioners in comparison to their male counterparts can be attributed to women taking on more roles as primary healthcare providers for their families, in line with societal traditions. Consequently, the responsibility of treating individuals with alcohol-related disorders often falls upon women. Furthermore, the notable representation of older individuals among the participants in this survey corresponds with observations in other studies conducted in Uganda and the wider region (Mukazayire et al., 2011; Kamagaju et al., 2013). Older individuals in society often possess extensive knowledge of medicinal plants and their uses, attributed to their prolonged and direct interaction with plant resources.

Diversity of medicinal plants

Our observation that the most utilized plant species employed by traditional medicine practitioners belonged to the Asteraceae family aligns with other studies in Uganda and other African regions which acknowledged its significant medicinal value (Hamill et al., 2000; Tefera and Kim, 2019; Ssenku et al., 2022). These plants are widely distributed in Uganda and the chances of TMPs using them for medicinal purposes are high (Mbatudde et al., 2007). The predominant use of these families may also be due the fact that most plant species in this family are mainly herbs and shrubs, so grow quickly and available throughout the year. The four most commonly used ethnomedicinal plant species were D. fragrans, C. canephora, S. officinarum and M. scandens. In contrast, only one plant, Dracaena steudneri Engl., belonging to the Dracaenaceae family, was identified for its use in treating alcohol-related disorders in an ethnobotanical study carried out in communities surrounding Mabira Forest in Central Uganda (Tugume et al., 2016). This finding confirms the use of medicinal plants in the traditional treatment of alcohol-related disorders across different regions of Uganda.

Plant life forms and parts used

Comparable to other studies, this survey found that herbs were the most predominant plant life form utilized by the TMPs for treating alcohol-related disorders, with shrubs and trees following in frequency. The common use of herbs, trees and shrubs has been reported in most studies in Uganda and elsewhere (Nankaya et al., 2019a; Ojelel et al., 2019; Girma et al., 2022). Their widespread utilization can be attributed to their abundance in gardens, bushes, and forests, as well as their ease of collection. The high utilization of leaves could be attributed to the ease with which they can be collected in large quantities compared to other plant parts (Nankaya et al., 2019b). Studies reporting the preference for leaves by traditional medicine practitioners suggest that it is driven by their abundance and the high concentrations of compounds with diverse medicinal properties found within leaves (Nankaya et al., 2019b). Similar findings have been described in Uganda (Hamilton, 2004; Kamatenesi-Mugisha and Oryem-Origa, 2007; Ssegawa and Kasenene, 2007; Okot et al., 2020; Mongalo and Raletsena, 2022) and other countries in Africa (Mongalo and Raletsena, 2022; Feyisa et al., 2023). The prevalent utilization of leaves, roots, flowers, and barks in herbal medicine preparations is a widespread practice across numerous communities in Uganda, as documented in central Uganda (Kamatenesi et al., 2011), southern Uganda (Ssegawa and Kasenene, 2007), western Uganda (Asiimwe et al., 2013), communities surrounding Kibale National Park (Namukobe et al., 2011), and Mpigi in central Uganda (Schultz et al., 2020). Similar practices are also reported in other countries, such as Tanzania (Amri and Kisangau, 2012), Ethiopia (Moges and Moges, 2019) and Italy (Petelka et al., 2020).

Homogeneity of use

A relatively high ICF observed in this study is comparable to other studies. High ICF were noted for plants used by traditional medicine practitioners in treating breast cancer (Lutoti et al., 2023), malaria (Adia et al., 2014) and other ailments (Ssenku et al., 2022). Other studies in Uganda have reported even higher ICF levels of up to 0.9 (36). The high ICF signifies high levels in agreement among the healers on the plants used to treat alcohol related disorders. The difference in informant consensus factor in this study compared to others may stem from variations in ecological diversity and the extent of knowledge sharing within the study areas.

Preparation and administration of remedies

The methods employed by the TMPs in preparation of medicinal plant remedies in our study aligns with the findings of another study conducted in southwestern Uganda (Gumisiriza et al., 2019) which highlighted crushing/pounding then mixing in water as a common method for preparing herbal remedies. Powders are preferred primarily for their prolonged shelf life, proving especially beneficial when utilizing seasonal plant parts like flowers and fruits. In contrast, infusions are consumed within a day, while decoctions are stored in tightly sealed containers for at least 1 week at room temperature. However, this finding contrasts with other research conducted in Uganda and the broader East African and African regions, where decoction is frequently identified as the dominant method of herbal preparation (Alebie et al., 2017; Gumisiriza et al., 2023). Decoctions may be preferred when the part of the plant used is available all year round such as leaves and bark. The widespread use of water as a solvent is attributable to its ready availability and its ability to dissolve a large number of metabolites. This property allows for the swift extraction of active ingredients during the preparation of herbal remedies (Alebie et al., 2017). An interesting observation by healers of mixing the prepared powder or tincture into alcohol is contradictory. The healers may see this as the easiest method to administer the remedy.

Conclusion, limitations and recommendations

This ethnobotanical survey has shown that the traditional medicine practitioners in Bushenyi district use a wide diversity of plants species to treat alcohol related disorders. The relatively high Informant Consensus Factor suggests a significant level of agreement among TMPs regarding the use of the identified plants. A limitation of this study may be bias among the TMPs who may have withheld names of some of the plants they use. This was mitigated by recruiting a bigger number of the TMPs into the study. We recommend investigations into phytochemistry, potential safety, efficacy, and mechanisms of action of the identified plants, especially those with a high frequency of citation such as D. fragrans. Additionally, conducting clinical trials to evaluate the effectiveness of the identified plants would contribute valuable evidence to guide healthcare practices in alcohol treatment. This will be novel in the African region regarding plant remedies for alcohol treatment.
