Background
Ethnobotany investigates the interactions between humans and plants.Studies in ethnobotany encompass diverse connections between people and plants including their magical, religious, and therapeutic roles.Wild plants, a rich source of nutritional benefits significantly contribute to global food security.The increasing global awareness of the intrinsic value of these plants influenced by cultural perspectives and dietary choices highlights their potential to combat malnutrition, enhance diet diversity, and promote health.Embracing sustainable practices, wild plants emerge as a solution, fostering both ecological equilibrium and human wellbeing.Harnessing their capabilities holds the power to revolutionize worldwide nutrition and health environments [1].
Wild plants not only enrich global food diversity with their nutritional benefits but also promote eco-friendly practices, alleviating the strain on over-farmed lands.Embedded in various cultures as traditional dietary staples, these plants align with local food perceptions and preferences.Addressing malnutrition by offering essential micronutrients absent in processed foods, they exhibit resilience against climatic fluctuations.Understanding and promoting their nutritional advantages, aligned with sustainable practices and local preferences holds the key to enhancing global food security while preserving health and ecological balance [1,2].
The utilization of herbal remedies extracted from plants has a historical presence across diverse cultures.Despite the decline in local understanding of therapeutic and wild food herbs worldwide, plants continue to play a crucial role in our daily existence.Since the inception of medicine, natural products, especially plant-derived ones, have supported human health.The pharmaceutical industry recognizes plants with a long history of ethnomedicine use as a valuable source of drugs.Ethnobotany investigates the use of therapeutic plants in local contexts, particularly in regions where herbal remedies often considered safer and healthier persist.As the world increasingly adopts sustainable practices the significance of wild plants grows offering a bridge between ecological balance and human well-being [3][4][5][6].
The utilization of plants as medicine holds global significance for public health.Medicinal plants have been a part of traditional healthcare, providing solutions for various needs and promoting overall wellness.Phytotherapy, the use of herbs in therapeutic procedures demonstrates efficacy in treating infectious disorders.Ethnobotanical surveys play a crucial role in understanding the relationship between communities and wild species aiding in the identification of new medications.In many remote and underdeveloped regions, the primary healthcare system relies significantly on medicinal plants, emphasizing their invaluable role as a natural resource [7].
Ethnomedicine explores how different cultures perceive health, illness, and disease influencing how people seek care and engage in healing rituals.Plants are indispensable for the survival of all species including humans, serving as major producers and transmitters on Earth.The intricate chemicals in therapeutic herbs contribute to the food, cosmetics, and medical industries.Herbalbased medications have made substantial contributions to human health providing sources for modern medications and prescriptions [8].
The World Health Organization defines medicine originating from plants as the sum of knowledge, skills, and practices based on indigenous theories and experiences.The scientific community's recent interest in the therapeutic potential of medicinal plants has historical roots dating back to the 1950s.Traditional medicine remains a primary treatment for approximately 70% of people in poor nations indirectly impacting industrialized countries relying on medicinal plants for pharmaceutical products.Traditional healers continue to play a vital role in rural communities preserving traditional knowledge and contributing to regional health structures [9][10][11].
Approximately 80% of the world's population uses herbs for treating illnesses and maintaining health.Mountainous and rural populations heavily depend on herbal flora for nutritional and food needs.Medicinal herbs are crucial for various medical conditions including heart and hepatic diseases, microbial infections, and non-communicable diseases like diabetes mellitus.Ongoing scientific efforts aim to develop potent antibacterial drugs with fewer adverse effects from these biofilm infections [12].
Pakistan's diverse topography encompassing mountains, plains, beaches, and deserts hosts a wide variety of medicinal plants impacting the lives of its residents.Ethnopharmacological data on plants used for pediatric diseases offer valuable insights.An ethnobotanical survey in Dunyapur, District Lodhran, Pakistan highlights the importance of traditional wild flora and their role in local health care (Fig. 1).The study aims to identify and explore plants used in ethnomedicine employing quantitative analysis through ethnobotanical techniques.

Ethno-botanical survey and data collection
The initial research objective involved the collection and identification of wild flora in Dunyapur with strict adherence to the ISE code of ethics (http:// ethno biolo gy.net/ code-of-ethics/) during data gathering.Direct interviews were conducted using a structured questionnaire, supported by the Rapid Appraisal Approach (PRA).Introducing ourselves as the researchers, we established a brief rapport with respondents to ensure their confidence before commencing interviews.Given that a majority of informants, including farmers, housewives, and hakims did not converse in English, a questionnaire was translated into their local language (Punjabi), and their responses were then documented.The information provided by locals encompassed details such as local names, recipes, local usage, the plant part utilized, and their participation in data collection.For each plant species

Methods of quantitative ethnomedicinal data analysis
The assessment of the data involved the application of descriptive statistics, as well as qualitative and quantitative analysis methods.Ethnobotanical data were examined using Microsoft Excel spreadsheet software version 2016 and SPSS version 25.

Family Importance Value (FIV)
To evaluate the relative significance of families, the FIV was used.It was computed by dividing the number of informants who mentioned the family by the total number of informants [13].
Where "FC" is the number of informers revealing the family, while "N" is the total number of informants who participated in the research.

Popular therapeutic use value (POPUT)
POPUT is a metric used to calculate the importance of a plant species for medicinal and therapeutic uses.Using the following formula, values for POPUT were determined [14].
"NURIT" refers to the number of use reports for each sickness or treatment effect."TUR" is the total number of use reports.

Informant consensus factor (ICF)
The ICF was developed as a result of the search for the informant's agreement on the stated treatment for each category of disease and determined by the given formula [15].

POPUT =
NURIT TUR Where "Nur" explains the total use report for each category, while "Nt" explains the taxonomic numbers used.An estimate of the significance of each plant taxon in conventional knowledge is provided by consensus information-gathering methodology.The informant's agreement with the species that are used to cure a specific ailment falls under the rank of high ICF.

Plant part value (PPV)
Plant part value is a measure of the relative importance of different plant parts in traditional medicines.The PPV of a plant species can vary depending on the cultural context and the specific needs of the community.It is computed what proportion of the plant's components such as its root, seed, leaves, flower, fruit, etc. are used [15].Where ∈ RU(plantpart) = thesum of uses reported per part of the plant and ∈ RU = total number of uses reported of all parts of the plant.

Relative frequency citation (RFC)
The formula below was used to calculate the index of the relative frequency of citations [15].
Where FC is the number of informants who reported using a species and N is the total number of informants.

Use value (UV) of plant species
It is the quantitative measure of the relative significance of locally known plant species and was determined using the given formula [15].
Where "UV" denotes each species' use value, "Ui" indicates the number of uses recorded by each informant for a specific species, and "N" is the total number of informants.

Relative Importance (RI)
According to their relative importance (RI), each plant species' use and the body organ systems it treats are rated [16].It is determined as.
Where "R.Ph" denotes relative pharmacological traits."R.Ph" is determined by dividing the number of uses (U) by the total number of use reports in the whole study."R.BS" indicates relative body systems treated.The "R.BS" value is obtained by dividing the number of body systems treated by a plant species by the total number of body systems studied.

Fidelity Level (FL)
To determine the value of the species associated with medicines, the fidelity level was determined [16].
"Np" is the number of species in a particular category."N" is used to accurately total consumption for specific species.

Relative Popularity Level (RPL)
RPL is the ratio of the total number of informants for all diseases to the number of ailments healed by a specific plant species.Plant species with comparable FL may, however, have different therapeutic capacities.The relative popularity level (RPL) assumes a value between 0 and 1.0, with 0 denoting no ailments that a plant species treats and 1.0 denoting the entire popularity of a plant for significant ailments.The popularity index would be at its highest point (1.0) when all plant species were regularly employed to treat some serious illnesses; it would then decline toward zero as the relative popularity of the species veered away from the popular side.For species of popular plants, the RPL value is sensibly chosen to be unity (i.e., 1), but for species of unpopular plants, the RPL value is less than 1.It is determined whether a plant species is popular or unpopular based on its relative popularity level (RPL).Each plant's RPL value can be calculated based on its precise location on a graph [16].

Rank Order Priority (ROP)
Plant species with different fidelity levels (FL) and Relative popularity level (RPL) values are properly ranked using a correction factor known as ROP.The ROP is made from the FL by multiplying the RPL and ROP values [16].

Frequency index (FI)
To summarize the ethnobotanical data, a descriptive statistical method (percentage and/or frequency) was used.The Frequency Index (FI) was calculated using the following formula for the quantitative data analysis of the ethnomedicinal plants [17].
Where "FC" is the number of traditional healers who mentioned the use of species and "N" is the total number of respondents.

Cultural significance index (CSI)
The cultural significance index (CSI) was used to determine how well-aligned informant knowledge was with the use of reports for a particular species.The following formula was used to calculate [18].
While "i" refers to the management of species that significantly affect the community, "e" indicates the informant's preference for one plant species over another for a specific purpose (value 2 for preferred species and value 1 for non-preferred species) and the letter "c" denotes the frequency of use of a plant species (a species that is cultivated, managed, or operated in any way receives a score of 2 and a score of 1 if the species is still free of any kind).

Family use value (FUV)
Family use value (FUV) is a measure of the importance of plant species to a particular family.To determine the significance of plant families, the FUV is calculated by using this formula [18].
Where "ns" is the overall number of species within a family and "UVs" is the total usage value of all the species within that family.

Preference Ranking (PR)
To discover which medicinal plant was best for each type of disease, a preference rating exercise was used.The medicinal plant that participants thought would be most effective in curing the stated diseases would be given the highest value in this activity.While the one that they thought would be the least successful would be given the lowest value.The scores for each species were added to determine the rank.This made it possible to identify the plant that the locals use to cure the conditions that are frequently reported [18].

Jaccard index
This index is used to compare study data to other ethnobotanical studies undertaken in different countries around the world, as well as among indigenous groups in the examined locations.The formula for calculating the JI index [18] where "a" is the recorded number of species of the study area "A, " "b" is the documented number of species of the area "B" and "c" is the common number of species in both areas' "A" and "B."

Results and discussion
Across diverse areas within Dunyapur, situated in District Lodhran, Pakistan, inhabitants employ varied remedies for a spectrum of illnesses.The present study emphasizes 41 plants spanning 28 families.Extensive field visits were conducted across multiple study sites to accumulate data on ethnomedicinal knowledge.

Socio-demographic features of informants
In the course of fieldwork aimed at gathering essential ethnomedicinal information regarding medicinal plants, a total of 496 informants were interviewed regarding 41 plants, with 59% being men and 41% women.The predominant data collection occurred among adults aged 51 to 60.The documentation of indigenous traditional knowledge was facilitated through the utilization of a questionnaire and interview methodology, actively involving knowledgeable individuals such as farmers, Pansars, herbalists (Hakims), and other residents including housewives, LHVs, teachers, and shopkeepers as outlined in Table 1.The criteria for informant selection prioritized individuals with diverse expertise, with a majority consisting of farmers (35%), Pansars (12%), and herbalists (Hakims) (9%).The higher representation of these groups could be attributed to their significant roles in traditional knowledge about medicinal plants.Farmers often possess valuable insights into local flora due to their close interaction with the environment.Pansars, known for their expertise in traditional medicine and herbalists contribute specialized knowledge making them key informants.This distribution aligns with existing literature highlighting the prominence of these groups in ethnobotanical studies [19].
The predominant life span preference in the study area was perennial (56%), with annual species accounting for the remaining 44%.All these species were reported to possess specific medicinal uses, as illustrated in Fig. 4a  and b.Notably, among the fifty-one therapeutic plants identified, herbs constituted the majority, encompassing 57% of the total.Trees followed, with fifteen species, along with seven species of shrubs, most of which were perennial, although some were annual and biennial species [20].This aligns with findings from a survey in the Shigar valley, Northern Pakistan, where herbs were also the most frequently utilized (51%), followed by shrubs (40%), trees (7%), and shrublets (2.85%) [21].In our study, herbs were the most commonly documented growth habit, followed by shrubs and trees, respectively.The dominance of herbs in the current research, comprising 68% of the documented plant species, may be attributed to several factors consistent with findings in existing literature.Herbs often exhibit faster growth rates, adaptability to various ecological conditions, and shorter life cycles, making them more accessible for local communities in need of immediate therapeutic solutions.Additionally, herbs are commonly found in diverse ecosystems and are easily cultivated, enhancing their prevalence in traditional medicinal practices.The comparatively lower representation of shrubs, trees, and grasses (15%, 10%, and 4% respectively) could stem from their longer life cycles, slower growth rates, and specific habitat requirements, limiting their abundance in the local landscape.This aligns with findings in the literature that highlight the preference for herbs in ethnomedicinal uses due to their versatility, ease of availability, and rapid regrowth capacities, contributing to their prominence in traditional healing practices.

Method of preparation
The preparation of remedies from the 41 documented plant species was categorized based on their applications in medicinal formulations.The study revealed that decoction (23%) emerged as the predominantly utilized preparation technique among the locals, followed by juice (20%), paste (18%), powder (12%), infusion (10%), herbal tea (9%), and other methods (8%), encompassing tincture, ointment, lotion, steam, burning smoke and maceration (Fig. 5).Comparative analysis with existing studies corroborated these findings, highlighting the prevalence of decoction as the most utilized method in herbal remedy preparation.Notably, decoction was identified as the most preferred technique (17%) in a prior study, followed by paste (15%), powder (13%), extract (12%), and juice (13%) [22].Another ethnobotanical study underscored the versatility of local remedies, indicating that decoction (71.4%), extract (66.7%), infusion, paste (38.1%), and powder (33.3%) were the primary modes of preparation, with juice and ash being less commonly employed (14.3%) [23].The dominance of decoction, juice, and paste in medicinal preparations may be attributed to their efficacy, simplicity, and cultural preferences as suggested by existing literature.The versatility and ease of application of these methods contribute to their widespread use in traditional medicine.

Quantitative ethnobotanical data analysis
The quantitative ethnobotanical analysis includes the calculation of some indices which are explained below.

Plant part value (PPV)
In the research area, community members employed various plant components, either in combination or independently, to address human ailments.The most frequently utilized part in herbal remedies was leaves (27%), succeeded by whole plants (21%) and roots (16%) (Fig. 6).The prevalence of these particular plant parts in traditional medicine may stem from their practicality and accessibility.Leaves, for instance, are often easily harvested without causing harm to the plant, ensuring sustainability in herbal preparations.Comparative analysis with other studies revealed a similar pattern, where leaves were the most popular plant part in herbal remedies, accounting for 30.2% of usage.Locals' preference for leaves could be attributed to their ease of collection and widespread availability.Moreover, various studies consistently highlight leaves as the primary plant part employed in traditional recipes, emphasizing their bioactive compounds such as alkaloids, flavonoids, and essential oils, which contribute to potential health benefits.The recurring mention of leaves across different studies underscores their significant role in herbal medicine [24].

Family use value (FUV)
Resedaceae attained the highest use value score of 0.38 in our study, underscoring its significant role in Fig. 6 Percentage of various parts of the plant in ethnomedicinal application traditional medicinal practices (Fig. 7a).Nyctaginaceae and Salvadoraceae followed closely with scores of 0.  = 0.083), Poaceae (FUV = 0.074), Rutaceae (FUV = 0.044), Thymelaeaceae and Urticaceae (FUV = 0.036 each), Cucurbitaceae (FUV = 0.034), and Ericaceae (FUV = 0.024).Families with a usage value less than 0.024 were deemed less significant in terms of cultural use in this context.The variation in family use values highlights the importance of considering local contexts and ecological factors in understanding the cultural significance of plant families across different regions [25].
The high FUV of Nyctaginaceae and Salvadoraceae (both with a score of 0.36) in our study could be attributed to several factors.First, these plant families may have a rich diversity of species with significant traditional uses in the local context.The presence of plants from the Nyctaginaceae and Salvadoraceae families that are frequently utilized for medicinal, cultural, or economic purposes might contribute to their elevated FUV.Additionally, these families may encompass species with versatile applications, addressing various human needs, thus increasing their cultural significance.Comparisons with available literature would be beneficial to discern whether the findings align with patterns observed in other regions and ecosystems.On the other hand, Cucurbitaceae (FUV = 0.034) and Ericaceae (FUV = 0.024) having comparatively lower FUVs could be due to factors such as limited cultural uses or a lower diversity of species with significant traditional importance in the study area.The reduced FUV might indicate that the plants from these families are less frequently employed or have a narrower range of applications in the local context.The literature should be consulted to explore whether the lower FUV for Cucurbitaceae and Ericaceae aligns with patterns observed in other regions, shedding light on the cultural and ecological factors influencing the significance of these plant families.

Family Importance Value (FIV)
Among the 41 plants studied, a total of 28 different families were identified.Poaceae emerged as the largest family with four species, constituting 11% of the total, followed by Boraginaceae, Fabaceae, and Solanaceae, each comprising 9% with three species each.Amaranthaceae, Polygonaceae, Apocynaceae, and Malvaceae accounted for 5% with two species each.Cyperaceae, Chenopodiaceae, Cucurbitaceae, Frankeniaceae, Oxalidaceae, Asphodelaceae, Salvadoraceae, Moraceae, Meliaceae, Brassicaceae, Apiaceae, Cleomaceae, Zygophyllaceae, Nyctaginaceae, Molluginaceae, Capparaceae, Pontenderaceae, Resedaceae, Caryophyllaceae, and Asteraceae comprised the lowest percentage at 2%, each with one species (Fig. 7b).In Toba Tek Singh District, 16 different plant families were represented, with Fabaceae leading with five species, followed by Asteraceae and Amaranthaceae tying for second place with four species each.Poaceae and Euphorbiaceae had two species each.In Haroon Abad, district Bahawalnagar, the natural flora consisted of 81 species across 21 families, with Poaceae dominating as the largest family with 15 species, followed by Euphorbiaceae (8 species), Asteraceae (7 species), and Amaranthaceae (7 species).The distribution of species across families varied in different regions, reflecting the ecological diversity and local conditions influencing plant composition [26].
The high FIV of Poaceae, Boraginaceae, Fabaceae, and Solanaceae in our study, with each family having three species, may be attributed to several factors.First, these families could exhibit a significant presence in the study area, with multiple species playing crucial roles in local ecosystems, traditional practices, or cultural significance.The ecological abundance and versatility of these families might contribute to their elevated FIV.Additionally, these families may encompass plant species with diverse uses, addressing various human needs such as medicinal, cultural, or economic purposes.The families' collective importance could be a result of the combined utility of their constituent species in the daily lives of the local community, making them stand out in terms of ecological and cultural significance.Comparisons with available literature and ecological studies specific to the region could provide further insights into the reasons behind the high FIV of Poaceae, Boraginaceae, Fabaceae, and Solanaceae in the study area.Understanding the ecological, cultural, and economic roles of these families in the local context would shed light on their importance in the studied ecosystem.

Popular therapeutic use value (POPUT)
In our study, various plant species exhibited distinct Medicinal Use Values, reflecting how respondents utilize specific plants for particular diseases.In the current research, these values ranged from 0.6 to 0.004.The highest value was attributed to analgesic effects (0.6), followed by jaundice (0.48), ulcer treatment (0.3), fever management (0.07), and equal values for diarrhea and skin diseases (0.006 each).Inflammation, cough, liver diseases, cancer, and kidney diseases shared a value of 0.04, while stomach-related ailments, asthma, piles, gargles, eye diseases, rheumatism, snake bites, hepatitis, and constipation were assigned values of 0.03 each.Wound healing received a value of 0.02, while diuretics, gonorrhea, laxatives, cardiac diseases, and blood purification were associated with 0.01 each.Anti-microbial properties and pain management were linked to values of 0.006, while the lowest values were recorded for cholesterol and diabetes (0.004 each).Respondents ranked these values from the highest to the lowest based on their perceptions (Table 2).Comparatively, a Turkish study presented diverse POPUT values, with shortness of breath at 0.11, abdominal discomfort at 0.10, wound treatment at 0.08, and stomach issues at 0.07, among other examples.The current investigation provides unique insights, highlighting analgesic properties with the highest value (0.6), while cholesterol and diabetes received the lowest values (0.004 each).
The observed high POPUT values for analgesia, jaundice, ulcer, fever, diarrhea, and skin diseases (ranging from 0.6 to 0.006) in our study could be influenced by the prevalence and perceived effectiveness of traditional remedies for these particular health concerns in the local community.Analgesic properties are often sought after for pain relief, which might contribute to its prominent ranking.Similarly, jaundice, ulcers, fever, diarrhea, and skin diseases are commonly encountered health issues, and traditional medicinal practices often focus on addressing these ailments.The local abundance of plants with known efficacy against these specific health concerns could also contribute to their higher POPUT values.However, variations in the prevalence of certain diseases and the cultural significance attached to them could explain the differences in POPUT values.Comparisons with available literature and ethnobotanical studies specific to the region can provide insights into the cultural and ecological factors influencing the popularity of certain therapeutic uses over others [27].

Informant Consensus Factor (ICF)
The ICF serves as a metric indicating the degree of association between specific plant species and their use in treating particular ailments.In our survey, ICF values ranged from 0.6 to 1, with the highest values assigned to cholesterol, cardiac diseases, antimicrobial properties, snake bites, blood purification, gonorrhea, and gargles (1 for each).Subsequent high values were recorded for analgesic (0.92), kidney-related issues (0.87), laxative, pain, hepatitis, and stomach ailments (0.83 for each), followed by eye diseases (0.81), piles (0.8), constipation (0.78), fever (0.77), diuretic, jaundice (0.76), rheumatism, liver conditions, and diarrhea (0.75), cough, asthma (0.73), cancer, skin diseases, and wound healing (0.72), ulcer (0.69), inflammation (0.65), and diabetes (0.60) (Table 2).In a parallel ethnobotanical survey in Tehsil Gojra, District Toba Tek Singh, high ICF values were documented for mental disorders and epilepsy (1), possibly attributed to the infrequency of these diseases in the region, leading to a focused use of specific plant species.This contrasts with our findings, where maximum ICF values were assigned to cholesterol, cardiac diseases, antimicrobial properties, blood purification, snake bites, gonorrhea, and gargles.Another survey indicated ICF values ranging from 0.66 to 0.93 for constipation and respiratory problems, with an average ICF value of 0.87 for plant utilization in treating various ailments among informants [28].The highest ICF values, reaching 1, for cholesterol, cardiac diseases, antimicrobials, snake bites, blood purification, gonorrhea, and gargles in our study could be attributed to the specific cultural and medicinal significance assigned to plants addressing these health concerns in the local community.Certain diseases, such as cardiac issues and infections, might be prevalent or culturally prioritized, leading to a concentrated use of plants believed to be effective against them.Analgesic (0.92), kidney-related issues (0.87), laxative, pain, hepatitis, stomach ailments (0.83 for each), and eye diseases (0.81) also received relatively high ICF values, suggesting their perceived importance in the traditional pharmacopeia.The variation in ICF values may be influenced by factors such as disease prevalence, cultural beliefs, and the perceived efficacy of traditional remedies.

The Cholistan Desert exhibited a maximum JI value at 12.60 while Deosai National Park reported the lowest (JI=0.00).Internationally, Saudi Arabia demonstrated the highest JI at 4.20.These comparative analyses provide insights into the ethnobotanical diversity and similarities among different regions contributing valuable information to the existing body of knowledge.The JI values calculated for the comparison of the present work with previous studies reflect the extent of similarity in medicinal plant species composition across different regions.The varying JI values can be attributed to several factors influencing plant diversity and traditional knowledge, including geographical, environmental, and cultural aspects.Firstly, the higher JI values, such as the one reported for the Cholistan Desert (JI=12.60)suggest a significant overlap in medicinal plant species between the study area and that specific region.This could be due to similar ecological conditions, shared plant resources or cultural exchanges that have contributed to a common pool of traditional knowledge.Conversely, the lowest JI values, like the one recorded for Deosai National Park (JI=0.00)indicate a complete dissimilarity in medicinal plant species.This lack of overlap could be attributed to distinct environmental conditions, different ecological zones or unique cultural practices that influence the selection and use of medicinal plants.Comparisons with studies in Hafizabad and other regions revealed varying degrees of commonality.The number of shared species and the resulting JI values highlight the regional specificity of ethnobotanical knowledge.Similarities may arise from historical connections, migration patterns or shared ecological features while differences influenced by local preferences, climate variations or unique cultural practices.
