Abstract | This study explores and documents the traditional medicinal uses of weed flora commonly found in field crops (rice, vegetables, wheat, and maize) in District Dir Upper, Khyber Pakhtunkhwa. Many medicinal plants grow wild or as weeds worldwide, including in Pakistan. The Dir Upper district boasts a diverse weed flora with significant medicinal value for daily use. Surveys using semi-structured open-ended questionnaires were carried out in distant villages of the Larjam subdivisions, specifically interviewing 120 local respondents (85 males, including herbalists and pansiris, and 35 women) regarding the naturally occurring medicinal weeds in the area. During the field survey, traditional knowledge and the ethnobotanical relevance of seasonal weeds were collected. A total of 65 species from 24 families were recorded across the four different seasons (spring, summer, autumn, and winter) in 2021–2023, including 54 angiosperms, 10 tracheophytes, and one pteridophyte. The dominant family was Poaceae (25%), followed by Asteraceae (15%) and Asclepiadaceae (2%). Given the essential roles that these weed species play in medicine, future research on the use and conservation of indigenous weed flora is highly recommended.

Introduction
Plants have been used for therapeutic purposes since prehistoric times. Ancient Unani documents, Egyptian papyrus, and Chinese traditional medicines mention herbs and weeds as therapeutic sources (Giannenas et al., 2020). Weeds, often considered unwanted plants, can flourish unexpectedly and mostly impact crop production. (Lemessa and Wakjira, 2015). However, not all weeds are unnecessary; in rangeland areas, annual grasses classified as weeds in agricultural fields are valuable as cattle feed and bird shelters (Bailey et al., 2019). They also serve as animal food and shelter, mitigate land degradation as soil-binding agents, and are frequently used in medicine and nutrition (Gupta et al., 2021). In Pakistan, weeds cause annual losses of 6.3 billion PKR in maize and 4.9 billion PKR in rice crops (Ahmed, 2022; Qadir, 2015). Weeds reduce agricultural productivity by competing with crops for natural resources such as water, nutrients, space, and sunlight. Consequently, local communities target the diversity of medicinal weeds (Rana and Rana, 2016). Instead of eliminating these weeds, it is recommended to investigate their therapeutic and ethnobotanical values. Traditional medical systems remain widely used due to population growth, insufficient medication availability, high treatment costs, complications of some synthetic drugs, and host responses to commonly used drugs for infectious diseases (Thomford et al., 2015).
Medicinal plants are considered extremely healthy because not all weeds are toxic and useless (Ekor, 2014). Herbal medicines can be used by individuals of all ages and genders, as this is a universally applicable truth. Several indigenous medicinal plants can be found growing naturally or cultivated in specific locations in Pakistan (Khan et al., 2013). Hence, conducting research on the flora and educating the local population about its significance are crucial steps to ensure the conservation of medicinal flora.
Ethnomedicinal data also aids taxonomists, pharmacologists, ecologists, wildlife managers, and watershed managers in their efforts to refine the economic status of residents in remote areas (Martinez et al., 2019). Various techniques and methods are used to research medicinal herbs in a specific area or on a particular plant. The locals also think that weeds are reducing the yield of their crops, so they use toxic chemical treatments like herbicides to eradicate weeds permanently (Davis and Frisvold, 2017). However, due to their lack of awareness of the distinction between usual and therapeutic weeds, they treat them similarly, adversely affecting the continual existence of medicinal weeds. This study is the first systematic investigation of the medicinal plant flora in District Dir Upper. Its primary purpose was to explore and document this flora. Our study aims to differentiate between medicinal and non-medicinal weeds in the study area. The current study strives to inform the general population about the medicinal potential of weeds, as they are commonly perceived as unwanted plants in the affected area.
Materials and Methods
Study area description
District Upper Dir is one of the largest districts and is a famous tourist spot in Khyber Pakhtunkhwa province. Before the establishment of Pakistan, Dir was an independent state that lasted until a presidential declaration in 1969; later, in 1996, it was separated into two Districts (Dir Upper and Lower). Dir Upper encompasses 3699 square kilometers (126500 hec). The Dir Upper district had a total population of 946,421, according to the 2017 census (Muhammad et al., 2021). Figure 1 shows the study area’s overall boundaries and geographic status. They are almost entirely Sunni Muslims, mostly Yousafazai Pathan, famous for hospitality and nobleness. The district is far from the capital; hence, no economic or business zone exists. Agriculture and herding is a vital source of the economy.
Demographic profile
The researchers used a detailed questionnaire to collect information about the ethnomedicinal uses of plants from residents and Traditional Health Practitioners. Many locals were interviewed, including people of various occupations, ages, and gender. Most respondents were farmers or plant traders, indicating a rural lifestyle. The majority of urban respondents were educators and small business owners. When selecting informants, folk knowledge, location, occupation, and age were all considered. Priority was given to older people and natives. Most participants were between 45 and 68, as shown in Table 1. All of the participants had extensive knowledge and experience with medicinal plants. Several suggestions and recommendations were made, including local names, traditional uses, and ethnobotanical information. We followed the ‘International Society of Ethnobiology’s guidelines for conducting ourselves ethically during the interview (Grasser et al., 2016). To ensure clarity and simplicity, the survey was conducted in the area’s native language (Pashto).

Results and Discussion
Ethnobotanical diversity
A total of 65 species belonging to 24 families, in which 54 species of angiosperms, 10 species of Tracheophytes, and one of Pteridophyta were recorded. The Poaceae was the dominant family, having 16 species, followed by Asteraceae with (10 species), Brassicaceae (3 species), Amaranthaceae (5 species), Asclepiadaceae (1 species), Aizoaceae (1 species), Caryophyllaceae (2 species), Chenopodiaceae (3 species), Cucurbitaceae (1 species), Convolvolaceae (3 species), Cyperaceae (1 species), Euphorbiaceae (3 species). We found 58 herbs and 5 shrubs as their parts used as shown in (Figure 2). Family name, taxan name, common name, part used, habitat and ethnobotanical information were noted, as shown in Table 2.
Disease categories
Out of all medicinal weeds, the most plants are used for digestive issues, followed by skin diseases. Cyperus rotundus L. and Convolvulus arvensis L. are used to treat diarrhea malaria, and as laxatives. The latex produced by the euphorbia species is used to treat skin conditions. Fever, infections, and several other conditions are treated by using various species. Various herbs and shrubs cure wounds and lessen inflammation (Figure 3). Euphorbia helioscopia L. is used to cure digestive problems, athlete’s foot, and constipation. Wounds were treated with Euphorbia prostrata (Zahra and Rahman, 2018). Indigenous people employ the 173 medicinal plants identified by (Sen and Samanta, 2015) for various functions, including treating humans and animals. It is essential to assess and further explore the mentioned plant species utilizing their medicinal and biological properties.

Forms and mode of utilisation
Out of 65 plants, 49 were medicinal and could treat respiratory, viral, and bacterial conditions, while 3 species were used as wild vegetables, as shown in (Figure 4). The eight plant species benefited as fodder for livestock to fulfill their nutritional value. In addition to their nutritional significance, the plant’s leaves and fruits are frequently consumed in cooking and were termed wild vegetables. The 1% is applied for ornamental purposes and the making of baskets and ropes (Nedelcheva et al., 2011). The area’s valuable commercial and ethnomedicinal vegetation is disappearing. The area’s vegetation is strongly advised to be used and conserved sustainably.
Part used
The parts of plant species, i.e., leaves, roots, stems, milky latex, and seeds, were introduced for medicinal purposes. Weeds in different forms were utilised to develop remedies such as extracts, powdered pastes, and decoctions. 17% of the leaves were utilized as a hemostatic agent to halt bleeding. Additionally, the seeds had therapeutic effects in treating injuries and regulating body temperature, as depicted in Figure 5. Poaceae was recorded as a dominant family, consumed as cow fodder as shown in Figure 6. The natives used aerial parts, bark, bulbs, cones, fruit, flowers, gum, husks, leaves, needles, nuts, rhizomes, roots, seeds, shoots, and the entire plant for various ethnobotanical purposes (Ur-Rahman et al., 2019).
The study revealed that weed species in District Dir Upper possess significant medicinal properties, contributing to traditional healthcare practices. These findings underscore the importance of further research and conservation efforts to protect these valuable plant resources. Such efforts can help preserve traditional knowledge and ensure the sustainable use of medicinal weeds.
The study findings emphasize the varied use of different plant components for medical purposes, resulting in the development of numerous medicines from these sources. Leaves were employed as a hemostatic agent, while seeds had medicinal properties in treating injuries and regulating body temperature. The family Poaceae was recognised as the most prevalent, mostly used as feed, as reported by the indigenous people, who employed a diverse array of plant components for ethnobotanical objectives, demonstrating their profound traditional wisdom. Considering the crucial functions these plant species fulfil in medicine, it is strongly advised to conduct further investigations on the utilisation and preservation of native weed flora.
The study found that digestive and skin illnesses are treated with the most medicinal weeds.
Xanthium strumarium leaves are used antipyretic and respiratory disorder (Mouhamad, 2022). Brassica campestris fodder for cattle, leaves and flower use as vegetable, seed oils can be used for body massage (Dilshad et al., 2008; Shankar et al., 2019). According to (Jahan et al., 2014) Eclipta alba species is used to treatment of gastrointestinal disorder (Jahan et al., 2014). Digera muricata are used digestive disorder (Manimekalai et al., 2020). Calotropis procera use against stomachache and diuretic, for muscular pain (Ghosh et al., 2010). Stellaria media it’s used for itching skin treat various gastrointestinal disorders, asthma, diarrhea, measles, jaundice, renal, digestive, reproductive and respiratory tracts inflammations (Gulshan et al., 2012; Singh et al., 2020).
Euphorbia species latex treat skin disorders. Euphorbia helioscopia L. and Euphorbia prostrata treat further ailments, while herbs and shrubs treat wounds and inflammation (Alsaffar et al., 2021; Salehi et al., 2019). Indigenous people use medicinal weeds from prior research to heal humans and animals, demonstrating the depth of traditional knowledge and the necessity to further study these valuable weed species (Kunwar et al., 2019; Uprety et al., 2012).
The leaves of Conyza canadens were cooked as vegetables, and the seeds were eaten with rice. The Poaceae family, which was predominated, can treat both acute and chronic illnesses like cancer, cough, diarrhea, and epilepsy (Ngoua-Meye-Misso et al., 2019). Diabetes, hepatitis, cardiac difficulties, diarrhea, dysentery, piles, constipation, premature ejaculation, cold/flu/fever, respiratory tract problems, digestive problems, ulcers, tumour, and headaches were only a few conditions treated using recorded medicinal plants (Kadir et al., 2014). According to Kumari et al., (2019) some herbs were used to treat various ailments such as bronchitis, TB, and asthmatic cough. Diarrhea, dyspepsia, persistent constipation, vomiting, ulcers, skin inflammations, and many male and female sexual diseases (Kumari et al., 2019). Aaproxemetly 70% of people consume weed species for primary healthcare, making them essential natural resources with the potential to yield safe drugs and treatments (Smith-Hall et al., 2012).
Conclusions and Recommendations
According to this survey, most people depended on agriculture for a living, and current services were deficient in the area. Despite some weeds potential therapeutic benefits, local farmers frequently used several techniques to eradicate weeds and ultimately increase crop productivity. Toxic sprays like herbicides and weedicides seriously endanger the medicinal weed flora. Some species of plants, like Taraxacum, Chenopodium, and Rumex, are versatile and need careful management and conservation care. A few things directly affected the local flora, mainly the medicinal weeds and the vegetation in universal. Both immediate conservation efforts and local public awareness campaigns are urgently needed. Seminars and conferences are a couple of examples of these programs. Future research should focus on using and conserving indigenous weed flora to preserve traditional knowledge and promote sustainable use of these medicinal plants. Such efforts are crucial for maintaining biodiversity and supporting local healthcare practices.
