| Abstract|| |
Background: Local natural medicinal resource knowledge is important to define and elaborate usage of herbs, in systematic and organized manner. Until recently, there has been little scientifically written document regarding the traditional uses of medicinal plants in Al Bahah region. Objective: This pilot study aims to collect the ethnobotanical information from native populations regarding the benefits of medicinal plants of Al Bahah region, and determine if the traditional usage is scientifically established (proved) from literature. Materials and Methods: The survey collected data for 39 plant species recorded by informants for their medicinal benefits. The recorded species were distributed among 28 plant families. Leguminosae and Euphorbiaceae were represented each by 3 species, followed by Asteraceae (2 species), Lamiaceae (2 species), Apocynaceae (2 species), and Solanaceae (2 species). All the medicinal plants were reported in their local names. Analysis of ethnopharmacological data was done to obtain percentage of plant families, species, parts of plants used, mode of administration, and preparation types. Results: Total 43 informants were interviewed, maximum number of species were used to cure skin diseases including burns (3), wounds (7), warts (1), Leishmania (7), topical hemostatic (2), followed by gastrointestinal system, rheumatism, respiratory tract problems, diabetes mellitus, anti-snake venom, malaria, and eye inflammation. Conclusions: The study covered Al Bahah city and its outskirts. Ten new ethnobotanical uses were recorded such as antirheumatic and anti-vitiligo uses for Clematis hirsute, leishmaniasis use of Commiphora gileadensis, antigout of Juniperus procera, removing warts for Ficus palmata.

| Introduction|| |
Not <400,000 flowering plants are found on the earth. About 12% of them are used in the traditional medicine.,, About 10,000 of those plants have already been scientifically investigated and described. In Western medicine system, higher plant-derived substances constitute around 25% of prescribed medicines and 74% of the 121 bioactive plant-derived compounds were identified through research based on leads from traditional medicine. The knowledge of medicinal plant uses was acquired by means of trial and error and transmitted from the older to the younger people, but this knowledge and transmission are in danger because transmission between older and younger generation is not always assured.,
Indigenous knowledge of Saudi traditional medicine ancient and still available among the tribal and local people and medicinal healers (Hakim). In KSA, more than 1200 (over 50%) of the total flowering plants (2250) are expected to be of medicinal importance.,,,,,,, This indigenous knowledge and traditional experiences have been passed verbally devoid of documentation and the traditional healers are dying without passing their knowledge. Besides, the urbanization of the indigenous customs results in more and more loss of the old knowledge of this human heritage. Therefore, there is an urgent necessity for documenting those vast stores of knowledge through ethnobotanical surveys, before their disappearance from the community, especially in Al Bahah. Al Bahah region is located in the Southwest of Saudi Arabia, enjoying with different geographical regions - mountainous, plains, coastal, and high biodiversity. Until recently, there has been little scientifically written documentation regarding the traditional uses of medicinal plants in Al Bahah region., Therefore, we focused on our project on collecting and documenting the ethnobotanical knowledge in Al Bahah region.
| Materials and Methods|| |
Al Bahah region is located in the Southwest of the Kingdom of Saudi Arabia between Makkah region and Aseer region [Figure 1]. The city is located in an area surrounded by natural tree and agricultural plateaus. The province is famous for beautiful forests, wildlife areas, valleys, and mountains. The area contains more than 53 well-known forests dominated by Juniperus procera, among them are Raghdan, Ghomsan, Fayk, Skaran, and Aljabal. Al Bahah region is divided geographically into three different parts: High mountainous Sarah region with temperate weather and rich plant diversity due to relatively high annual rainfall, Eastern Tehama lowland coastal area with very hot and humid weather and very little average rainfall and the Eastern hills with cool winters, hot summers, and sparse vegetation cover. Main cities of Al Bahah region are Baljurashi, Almandaq, Qilwah, and Al-Mikhwah. The main two tribes of this region are Ghamid and Zahran. Al Bahah city experiences mild climate with temperatures ranging between 12°C and 23°C (53.6°F–73.4°F). Due to its location at 2500 m (8200 ft), the climate is moderate in summer and cold in winter above sea level. Humidity ranges from 52% to 67%. The mountainous region, As-Sarah, the weather is cooler in summer and winter. Annual rainfall in the mountainous region ranges between 229 and 581 mm. The average rainfall of the Al Bahah region ranges between 100 and 250 mm.
Information on medicinal plants was collected from Al Bahah and surrounding regions such as Baljurashi, Al Mandaq, and Miqwah from October 2015 to June 2016. Ethnomedicinal information was collected by ethnobotanical interviews with informants (43) (local users 18, knowledgeable persons in herbal shops (10), and traditional healers (15); ethnomedicinal properties (local name, parts of plants, ailments, the way of preparation, and administration) of plants were reported through informal, interviews, plants collected were taxonomically identified. Voucher specimens are preserved at the Department of Pharmacognosy, Faculty of Clinical Pharmacy, Al Baha University.
Descriptive statistical methods were applied to analyze and summarize the ethnomedicinal data such as percentage of families, species, administration types, preparation modes, and plant parts used.
| Results|| |
The survey collected ethnomedicinal information of 39 plant species recorded by informants for their medicinal benefits. The recorded species were distributed among 28 plant families. Leguminosae and Euphorbiaceae were represented each by 3 species, followed by Asteraceae (2 species), Lamiaceae (2 species), Apocynaceae (2 species, and Solanaceae (2 species). All the medicinal plants were reported in their local names listed in [Table 1], and used in more than 20 types of diseases. Maximum number of species was used to cure skin diseases (23 species; 42.6%) including leishmaniasis (8; 34.8%), wound healing (6; 26.1%), dermatitis (2; 8.7%), local hemostatic (2; 8.7%), inflamed gums (2; 8.7%), psoriasis (1; 4.3%), vitiligo (1; 4.3%), warts (1; 4.3%) [Figure 2] followed by the gastrointestinal system (10; 18.5%), rheumatism (6; 11.1%), anti-snake venom (3; 5.6%), antimalaria (2; 3.7%), cardiovascular diseases (2; 3.7%), urinary tract infection (2; 3.7%), diabetes mellitus (2; 3.7%),) and respiratory tract problems (4; 7.4%) [Figure 3].

The principal modes of preparation were paste (27.7%), oral raw consumption (23.4%), infusion (14.9%), decoction (8.5%), powder (6.4%), solutions (8.5%), and others (10.6%) [Figure 4]. Most preparations were drawn from a single plant, often plant parts (fresh or dried) were ingested orally. Some preparations of plant parts were mixed with honey, water, and milk to improve the palatability of remedies. Among various plant parts used (leaves, fruits, branch lets, roots, rhizomes, flowers, fruits, seeds, and latex), the most frequently used plant part was the leaf, constituting 49 % followed by fruit (11 %), roots (10 %), milky latex (10%), flowers (8 %), aerial parts (4 %), branches (4 %) and others (4 %) [Figure 5]. Twenty-three plant preparations obtained from 18 plants of the total reported medicinal plants are used externally or taken as a gargle), followed by 12 species which are taken orally and 8 other species which are used both externally and internally application. By comparing the literature review in the ethnobotanical studies in Saudi Arabia and neighboring countries (Arabian Peninsula) with the current study, it was observed that ten ethnobotanical uses of 8 studied plants have not been previously recorded [Table 2]. A use index (UI%) was calculated to determine the importance of the use of each medicinal plant. The used index formula is UI = (na/NA ×100), where na is the number of interviewers who cite the species as useful and NA is the total number of people interviewed.
| Discussion|| |
Traditional herbal medicine has played a significant role currently as a topic for scientific research, particularly when the literature and field work data have been properly assessed. Such evaluation findings can offer several plants that can have the priority to be studied for specific biological activity based on the traditional herbal uses. Ethnomedical uses of the plants can be utilized as an indicator for isolating bioactive compounds using bioactivity-guided fractionation method. This ethnomedicinal route provides positive activity in the order of 2–5 new compounds per 10,000 studied plants in comparison to the random route that gives positive activity in the order of one compound per 10,000 studied plants.,, In this study, ethnomedicinal information was collected from 39 medicinal plants belonging to 28 plant families. There is no dominance of any plant family with a higher number of plant species. However, plant families with herbs are represented by Leguminosae, Asteraceae, Lamiaceae, Solanaceae. Their use may be preferred because of their ready availability.
The most used medicinal plants, according to their UI [Table 1], were J. procera, Rumex nervosus, and Ziziphus spina-christi. Those three medicinal plants are widespread species in Al Bahah and available during the whole year. Different parts of the plants were used for preparing the herbal remedies. However, in the majority of the plants, the herbal preparations were obtained from the leaves (45%) and similar observation has been recorded for other forested communities with green vegetation and abundant leaves. It is known that leaves form a key part of plant identification and are the most easily available part to collect by local people.
In addition, the preference toward leaves may be because leaves are the main photosynthetic organ in plants and are responsible mainly for the biosynthesis of secondary metabolites that acts on the body as bioactive compounds. Hence, leaves are the source for photosynthates or exudates  that are toxins against environmental hazards and this character provides medicinal value to the human body. Most herbalists give remedies for skin diseases and sometimes for rheumatism in the form of washes and pastes, and for gastrointestinal diseases orally in the form of infusion, decoction, and oral raw consumption. Skin diseases were the most treated ailments by about 43% of herbal preparations mainly pastes and Leishmania and wound healing constitute the main skin diseases treated by 8 and 6 herbal preparations successively. At present, leishmaniasis is common in the human population in different localities, including the Eastern and Southern Province of Saudi Arabia and in particular endemic in the Al-Hassa Oasis. While the antileishmanial activity of Myrtus communis, Achillea biebersteinii, Olea europaea, and Dodonaea viscosa was proved,,,,, further antileishmanial screening should be done in the future for the following plants Commiphora gileadensis and Dorstenia foetida.
Rheumatic diseases, in particular, rheumatic arthritis, affectalmost 1%–2% of the population globally and attack women thrice as commonly as men. The spectrum of rheumatic diseases seen in Saudi Arabia appeared to be broadly similar to that seen in the West. In KSA, the rheumatic diseases affect 19.28/100,000 inhabitants. However, most of the Saudi patients tends to use the conventional medicines for managing such disease, some of them still use the medicinal plants, especially in rural areas and among the old people. In our study, six plants were reported to manage rheumatic diseases, Clematis hirsute, Psiadia punctulata, Moringa peregrine, O. europaea, Withania somnifera, and J. procera. The anti-inflammatory activity of P. punctulata, M. peregrine, O. europaea, Salvadora persica, and W. somnifera was reported, and therefore, their traditional uses in folk medicine are justified scientifically.,,,,,C. hirsute and J. procera should be tested for cyclo- and lipo-xygenase inhibitory activity and related bioassays to verify their uses in traditional medicine as anti-inflammatory agents. Reports were found to the hypoglycemic effect of O. europaea leaves, Retama raetam fruits and M. peregrine,,, but there has been no report about the hypoglycemic of R. nervosus that has been used traditionally as hypoglycemic agent.
When the present study is compared to ethnobotanical contributions done in KSA and neighboring countries, our findings disclosed that ten ethnobotanical uses of eight medicinal plants have been recorded for the first time [Table 2].,,,,,,,,, Little or no reports have been found so far regarding the bioactivity-guided fractionation of C. hirsute, J. procera, C. gileadensis, and D. foetida; therefore, those plants can be a target for further bioactivity-guided isolation. Ethnobotanical use in particular of C. hirsute for managing vitiligo should be proved using melanocytes bioassay, vitiligo, a disease that affects about 0.5%–1% of the world's population that means about 60 million suffering from this disease. The average age of onset is in the mid-twenties, but it can appear at any age. The disorder affects both sexes and all races equally; however, it is more noticeable in people with dark skin. Moreover, traditional antigout use of J. procera should be proved pharmacologically and the plant can be utilized economically for managing gout because the plant occurs as forests. It was reported that hyperuricemia is present in a considerable proportion of the Saudi people. Most of the plants used for treating wound healing showed antimicrobial activity.
| Conclusions|| |
In summary, this survey demonstrates that the culture of folk medicine is still practiced but on limited scale by the population in Al Bahah region. Pharmacological, toxicological, and phytochemical studies should be done for the promising medicinal plants mentioned in this research project, to assure their biological activity as well as their toxicity and then design therapeutic strategies based on the most effective and least toxic products in particular for J. procera and R. nervosus. J. procera can be utilized economically for medical purposes because it grows wild in vast areas in Al Bahah region.
