Indigenous Uses and Pharmacological Activity of Traditional Medicinal Plants in Mount Taibai, China.
1. IntroductionEthnobotany is a plant science that studies historical and current uses of medicinal plants [1, 2]. It is of great significance for the conservation of ancient medicinal cultures, as well as for understanding changes in history and culture. It is also important for the conservation of traditional medicinal plant resources [3]. Furthermore, local residents with limited access to medical technology and equipment may benefit from traditional remedies, which can form an effective indigenous healthcare system. Such research maybe significant in revealing important traditional medicinal plant species, often leading to the discovery of new drugs, and contributing to the local economy. Currently, millions of people in the developing world rely on traditional medicinal plants for primary healthcare, skin care, economic benefits, and cultural development. In areas where medical facilities are underdeveloped, traditional medicinal plants are especially important. Here, local residents may not distinguish between food, healthcare, and economic activity. This indigenous pharmacological knowledge of traditional medicinal plants should not be ignored. The global herbal remedies market was worth 19.4 billion USD in 1999 (not including shrubs and trees) [4]. Moreover, demand for traditional medicinal plants is increasing; for example, in India alone, the market is expanding at an annual rate of 20% [2]. The development of ethnobotany is expected to bring significant economic benefits, and scientific research is required to provide an evidence base for the development ofthe active ingredients of traditional medicines. Ethnobotany may also protect cultural heritage, inspire more studies of traditional medicines, and provide a basis for the discovery of new drugs.
Qinling is the most important northsouth geographical divide in China. The peak of Qinling is Mt. Taibai, which is the most important boundary in eastern mainland China in terms of climatic variation and the distribution of vegetation, and is especially significant because of its eastwest alignment and abundance of species [5]. Mt. Taibai has 1,850 species of plants belonging to 126 families, 25 of which are used in traditional Chinese medicine.
In recent years, interest has grown in the traditional medicinal plants of Mt. Taibai, both domestically and internationally. Attention has focused on biodiversity and pharmacological properties of individual species; however, few studies have attempted to evaluate their medicinal efficacy, or to explore the scientific basis of these plant medicines [6-8]. Although many of these plants have previously been investigated, most studies have been inconclusive. To provide a good evidence base for the usage of traditional medicinal plants, further studies should be carried out to investigate the distribution and usage of medicinal plants and critically evaluate their efficacy.
We investigated and documented traditional medicinal plants in Mt. Taibai and analyzed the treatment diversity of medicinal methods, identifying numerous plant parts, remedy formulations, and ailments that they were used to treat. We also evaluated the efficacy of these medicinal plants by comparing local usage with findings from published phytochemical and pharmacological studies. We believe that this research will not only help to stimulate the local economy, but also help to promote the protection and utilization of traditional medicinal plants.
2. Study Area and Methods
2.1. Study Area. Mt. Taibai (107[degrees]22'-107[degrees]5l' E, 33[degrees]49'- 34[degrees]05' N) is located in the center of the Qinling mountain range in Shaanxi Province, China. It covers Taibai County, the southern part of Mei County, and the southwestern part of Zhouzhi County. The elevation of the study region extends from 819 to 3767m (see Figure 1) [9]. The Mt. Taibai Nature Reserve was designated in September 1965 by the government of Shaanxi Province. It contains a diverse range of flora, including 1,783 seed plant species (597 genera and 126 families), 325 bryophyte species (142 genera and 62 families), and 110 fern species (40 genera and 21 families), constituting approximately 60% of the flora of the Qinling range [10-12]. Interviews and surveys, as well as specimen collection, were undertaken in the Taibai Mountains (Mt. Taibai) Nature Reserve and the surrounding areas, including villages in Taibai County, Mei County, and Zhouzhi County.
2.2. Study Methods. Pharmacological data were collected by conducting interviews with local experienced doctors of traditional Chinese medicine, and open-ended questionnaires were given to villagers. Participants were selected to include plant collectors, plant cultivators, and plant traders. In total, nine experienced doctors of traditional Chinese medicine were interviewed; all were male, five were aged more than 50 years, and four were aged 40-50 years. In addition, 41 villagers (74% male, 26% female) participated in our open-ended questionnaire, 54% of whom were aged more than 40 years. The majority (54%) had no formal education, and 46% had primary school education, of whom 21% also had secondary school education. We gathered information on the altitudes of plant distributions, plant uses, the parts of plants that are used, their modes of utilization, the formulations of remedies, and the ailments that were treated using them. For species that could not be identified with certainty, specimens were collected for identification using references and further expert knowledge. The informant consensus factor [F.sub.IC] was used to describe the variability of traditional medicinal plants. A high value of [F.sub.IC] indicates good agreement on a particular ailment, whereas a low value of [F.sub.IC] corresponds to poor agreement. High values of [F.sub.IC] thus indicate particularly interesting species in the search for bioactive compounds. [F.sub.IC] was calculated as follows [13]:
[mathematical expression not reproducible], (1)
where [N.sub.u]r is the number of individual reports of plant use for a particular illness category and [N.sub.t] is the total number of species used for this illness category.
To determine the variability, the reasonability of preparation methods, and the efficacy of the medicinal plants, we analyzed the altitudes at which the plants were grown, the taxonomic category, the parts of the plants that were used, the ailments that were treated, the chemical composition, and the pharmacological activity. Data were plotted using Sigmaplot 12.0, MapGIS 6.7, and Photoshop 6.0 for Windows.
3. Results and Discussion
3.1. Distribution at Different Altitudes. We recorded a total of 50 species of traditional medicinal plants grown at various altitudes on Mt. Taibai. Forty species were found at altitudes of 1000-1400 m, 23 species at altitudes of 1400-1800 m, 18 species at altitudes of 600-1000 m, 15 species at altitudes of 1800-2200 m, 14 species at altitudes of 2200-2600 m, 7 species at altitudes of 2600-3000 m, and 6 species at altitudes of 3000-3500 m (Figure 2). Therefore, we concluded that altitudes in the range of 1000-1400 m represented the best sampling location.
3.2. Taxonomic Categories. All of these species were angiosperms, with 46 genera belonging to 32 families. There were 41 species of herb (82%), 6 species of shrub (12%), and 3 species of climber (6%; see Figure 3). Shrubs and grassland are important habitats for medicinal plants [14]. The herb layer is more complex and variable than the shrub layer, and the interaction between species is strong. Owing to the heterogeneity of the herb layer, it has rich species diversity [15]. It is believed that the more abundant the plant, the more the medicinal virtues it may possess [16, 17].
3.3. Part of the Plant Used for Medicine. Medicinal formulations can be prepared from roots, rhizomes, seeds, leaves, flowers, fruits, stems, or the whole plant. In this study, the most commonly used part was the whole plant (27 species), followed by roots (18 species), fruits (11 species), seeds (7 species), leaves (5 species), rhizomes (5 species), stems (3 species), and flowers (3 species) (Figure 4). The use of multiple plant parts was also recorded in some cases, including Iris lactea, where the leaves, roots, seeds, or flowers may be used for medicine, and Acorus calamus, where the roots, flowers, or leaves are used. It has been shown that some traditional medicinal plants may have effects when used in the form of preparations made using roots, leaves, and flowers. Deng and Hou [18] carried out chemical analyses and pharmacological experiments using 18 plant roots, leaves, and flowers, with clinical observations and a comparative study showing that many nonmedicinal parts of plants had medicinal value, which is significant for the development of new medicinal resources. Many traditional Chinese medicines in nonmedicinal parts of in-depth research have new insights, in the development of new resources.
3.4. Ailments Treated. Gastrointestinal disorders, coughs, colds, urological problems, dermatological infections, heart diseases, fever, headaches, liver complaints, weakness, dizziness, respiratory problems, ophthalmological problems, cuts, and wounds were treated using traditional medicinal plants. Coughs and colds were treated with the greatest diversity of plant species (22 species), followed by urological problems (19 species) and gastrointestinal disorders (17 species). Respiratory problems, heart disease, and toothache were treated with the lowest diversity of plant species (5, 2, and 2, resp.) (Figure 5). Many species were used to treat multiple ailments, such as Solanum nigrum, Origanum vulgare, Lespedeza bicolor, Lespedeza cuneata, Carum carvi, and Valeriana officinalis, which were used to treat four to five ailments (Table 1). This suggests that there is significant potential value among these species. Some species were used to treat few ailments, such as Acorus calamus, which was used to treat only cough and toothache. Some species were used to treat only a single ailment, such as Thlaspi arvense, which was used to treat urological problems only (Table 1). The reasons why coughs, urological problems, and gastrointestinal disorders were treated with such a diversity of species maybe related to the local climate conditions, living environment, and habits.
3.5. Formulations. We found that 85 medicinal formulations were prepared using the 50 traditional medicinal plants identified in this study. Methods/applications included decoctions, pastes, juices, chewing, steaming, and medicated baths (Table 2). The most common formulation was decoction (42), followed by paste (25), juice (8), medicated bath (5), chewing (3), and steaming (2). Polygonum aviculare, Portulaca oleracea, Sanguisorba officinalis, Lespedeza cuneata, Tribulus terrestris, Pyrola rotundifolia, Verbena officinalis, and Veronicastrum sibiricum were processed into three different formulations (Figure 6). A total of 19 species were prepared as two different formulations, and all of the remaining 23 species were only prepared as a single formulation. Decoction was the most widely used preparation, which may be because of its simplicity and convenience (the processes of applying medicated baths, chewing, and steaming are more complicated or less convenient). Additional preparations have also been reported; for example, Chen et al. [19] described a preparation made using a combination of egg, tea leaves, and yellow wine, which was used as an embrocation to treat skin diseases, as well as the use of rice or other foods to enable swallowing or topical applications.
3.6. Informant Consensus Factor. The level of informant agreement was medium-high (mean [F.sub.IC] = 0.65). [F.sub.IC] values for most diseases were in the range of 0.60-0.70. Respiratory problems, menstrual disorders, and urological problems exhibited relatively low levels of consensus ([F.sub.IC] = 0.56, 0.67, and 0.57, resp.). High values of [F.sub.IC] were obtained for toothache and heart disease (0.88 and 0.83, resp.), showing that locals had reached good agreement on the plant species (Polygonatum odoratum, Valeriana officinalis, Acorus calamus, and Asarum sieboldii) to be used for these ailments. With the development of national medicine, a variety of herbs may contribute to traditional medicines and can complement the development of traditional Chinese medicine theory and practice [20]. These species may have significant value, so further investigation of their active compounds is warranted (Table 3).
3.7. Efficacy of Traditional Medicinal Plants. By collecting phytochemical and pharmacological data on the 50 traditional medicinal plants based on questionnaire data from local residents, and comparing this with bioefficacy data from literature reports, we found that the use of traditional medicinal plants in Mt. Taibai was consistent with known phytochemical or pharmacological properties in 84% of cases. In total, 28 medicinal species showed complete correspondence and 14 (Polygonum viviparum, Rumex acetosa, Tribulus terrestris, Paeonia obovata, Thlaspi arvense, Polygonatum odoratum, Actinidia arguta, Astragalus chrysopterus, Lespedeza bicolor, Solanum nigrum, Cynanchum wilfordii, Metaplexis japonica, Daucus carota, and Anaphalis sinica) showed partial correspondence. These results showing only partial phytochemical and pharmacological correspondence warrant further research into the uses of these plants. It was difficult to evaluate the pharmacological activity of the following eight species: Iris lactea, Lespedeza cuneata, Oxalis acetosella, Sophora flavescens, Lepidium apetalum, Leonurus pseudomacranthus, Ranunculus sceleratus, and Cephalanoplos segetum. Although many of these have been shown to contain active substances, further research is required to investigate their efficacy. The species Oxalis acetosella, Sophora flavescens,and Leonurus pseudomacranthus (Table 4) have not been widely studied, and their pharmacological activity is largely unknown. To help promote local economic development, we conclude that the previous 42 medicinal species should be given sufficient attention, but that the final eight species are also worthy of further research, with potential applications in drug development.
3.8. Suggestions for Further Exploitation and Protection. By comparing information on the use of traditional medicinal plants with the Chinese Materia Medica and other related research, we found that the properties of many of the identified species exhibited similar results. This shows that the use of traditional medicinal plants is self-consistent. This self-consistent knowledge of traditional medicinal plant species is extremely valuable and may promote research into the culture of traditional remedies and expedite the development of medicine. Therefore, knowledge of traditional medicinal plants is significant and should be conserved. Further development and utilization and effective cultivation and preparation methods, as well as education and regulation, are important strategies that can help exploit the benefits of these medicinal plants. Against this background, we make the following proposals.
First, regulations should be issued by government to control and standardize the use and trade of traditional medicinal plants. Second, the traditional knowledge of the use of medicinal plant is very important, but local residents may not take this seriously unless they realize the value of these traditional medicinal plants. Therefore, effective communication/publicity is important. Third, improvements should be made to the market for medical plants. Trade is an important factor in the use of medicinal plants, and protection for traders is therefore important. To promote economic development of local medicinal plants, protection and production should be taken into consideration. If such regulation is impractical, medicinal botanical gardens maybe a good option. Training and demonstrations are important not only to preserve the germplasm resources of wild medicinal plants, but also to improve publicity. Finally, support from government is an important factor, as the implementation of the above strategies requires support from government. Only government has the capabilities to ensure sustainable development of these medicinal plant resources.
4. Conclusions
Mt. Taibai is rich in medicinal plant resources, and the local people possess a systematic and self-consistent knowledge of these native medicinal plants, including identification, application, and treatment modalities. Altitudes in the range of 1000-1400 m were found to be most promising for sample collection. Herbs were the most widely used plant species because of their abundance and the relative ease of collection, preparation, and storage. The most frequently used parts of plants were roots. Coughs and colds were the ailments that were treated with the greatest diversity of medicinal plant species. Decoction was the most widely used formulation.
The level of informant agreement was medium-high (mean [F.sub.IC] = 0.65). The highest values of [F.sub.IC] were obtained for toothache and heart disease (0.88 and 0.83, resp.), indicating good agreement in terms of the plant species used to treat these conditions (P. odoratum, V. officinalis, A. calamus, and A. sieboldii). These species therefore have significant value, and further research into their active compounds is warranted. We found 84% self-consistency of traditional plant use, which, together with scientifically proven phytochemical and pharmacological properties, indicates that traditional medical theories and formulations may be important and effective aspects of healthcare. We found that 14 species (P. viviparum, R. acetosa, T. terrestris, P. obovata, T. arvense, P odoratum, A. arguta, A. chrysopterus, L. bicolor, S. nigrum, C. wilfordii, M. japonica, D. carota, and A. sinica) exhibited only partial correspondence in terms of pharmacological activity and that 8 (I. lacteal, L. cuneata, O. acetosella, S. flavescens, L. apetalum, L. pseudomacranthus, R. sceleratus, and C. segetum) showed inconclusive results; however, there may be significant potential for the use of these plants, and further investigation is warranted for all species. The chemical compounds contained in the species O. acetosella, S. flavescens, and L. pseudomacranthus have not been reported, and their pharmacological activity is largely unknown. More complete and systematic knowledge of the phytochemical and pharmacological properties of traditional medicinal plants is desirable, and medicinal plants have considerable potential for healthcare applications. Therefore, we attach importance to the conservation of biodiversity, as well as traditional knowledge of the medicinal use of these plants. Proper management and exploitation of traditional medicinal plants may provide a sustainable source of income for local communities. This provides incentives for conservation to ensure the long-term availability of these traditional medicinal plants, both for use as indigenous drugs and for commercial exploitation.
