Traditional herbal medicine in Far-west Nepal: a pharmacological appraisal

Abstract

Background

Plant species have long been used as principal ingredients of traditional medicine in far-west Nepal. The medicinal plants with ethnomedicinal values are currently being screened for their therapeutic potential but their data and information are inadequately compared and analyzed with the Ayurveda and the phytochemical findings.

Methods

The present study evaluated ethnomedicinal plants and their uses following literature review, comparison, field observations, and analysis. Comparison was made against earlier standard literature of medicinal plants and ethnomedicine of the same area, the common uses of the Ayurveda and the latest common phytochemical findings. The field study for primary data collection was carried out from 2006-2008.

Results

The herbal medicine in far-west Nepal is the basis of treatment of most illness through traditional knowledge. The medicine is made available via ancient, natural health care practices such as tribal lore, home herbal remedy, and the Baidhya, Ayurveda and Amchi systems. The traditional herbal medicine has not only survived but also thrived in the trans-cultural environment with its intermixture of ethnic traditions and beliefs. The present assessment showed that traditional herbal medicine has flourished in rural areas where modern medicine is parsimoniously accessed because of the high cost and long travel time to health center. Of the 48 Nepalese medicinal plants assessed in the present communication, about half of the species showed affinity with the common uses of the Ayurveda, earlier studies and the latest phytochemical findings. The folk uses of Acacia catechu for cold and cough, Aconitum spicatum as an analgesic, Aesculus indica for joint pain, Andrographis paniculata for fever, Anisomeles indica for urinary affections, Azadirachta indica for fever, Euphorbia hirta for asthma, Taxus wallichiana for tumor control, and Tinospora sinensis for diabetes are consistent with the latest pharmacological findings, common Ayurvedic and earlier uses.

Conclusions

Although traditional herbal medicine is only a primary means of health care in far-west Nepal, the medicine has been pursued indigenously with complementing pharmacology and the Ayurveda. Therefore, further pharmacological evaluation of traditional herbal medicine deserves more attention.

Background

Current estimates suggest that, in many developing countries, about two thirds of the population relies heavily on traditional practitioners and medicinal plants to meet primary health care needs [1]. Although modern medicine may be available in these countries, traditional herbal medicine is often been used for historical, cultural, and ecological reasons, in particular this is due to continued availability [2], better compatibility [3] and high acceptance [4]. Traditional herbal medicine possesses greater significance in Nepal Himalaya hence interest in herbal medicine has gradually increased in recent years [5]. As a result, the medicine all over the world is nowadays revalued by extensive researches on base materials plant species and their therapeutic principles, however to date only about five percent of the total plant species have been thoroughly investigated [6-8] to ascertain safety and efficacy of traditional medicines.

Plant species have long been the principal ingredients of traditional medicine [9] and their use dates back to the beginning of human civilization [10]. Herbal medicine has clearly recognizable therapeutic effects [11] as well as some toxic side-effects [12]. Thus, Nepalese medicinal plants with ethnomedicinal properties are being screened for their active pharmacological effects [13]. The present study therefore evaluated the ethnomedicinal uses of the selected 48 second priority medicinal plants of Baitadi, Dadeldhura and Darchula districts of far-west Nepal and comparatively assessed their uses against earlier standard literature on medicinal plants of the same area, the common uses of the Ayurveda (an ancient traditional system of herbal medicine in the Himalaya) and the latest phytochemical findings.

Materials and methods

The field study for primary data collection was carried out in the Baitadi, Dadeldhura, and Darchula districts of far-west Nepal from 2006-2008. The districts stretch between 29°01' and 30°15'N latitude, 80°03' and 81°09'E longitude and 357 m - 7132 m altitude. The study sites were Anarkholi, Dasharathchand, Jhulaghat, Khodpe, Kulau, Pancheswor, Patan, Salena, and Sera (Baitadi); Brikham, Jakh, Jogbudha, Patram, and Rupal (Dadeldhura), and Dumling, Gokule, Joljibi, Khalanga, Khar (Figure (Figure1),1), Lali, and Uku (Darchula). All three districts are situated along the western borders of the country and lie adjacent to India. Due to variations in altitude, topography, and bio-climate within the districts, the diversity of medicinal plants and knowledge of utilization are vast. The subsistence use is profound particularly for home herbal healing [5,14]. There are a number of diverse ethnic groups in the area. The largest ethnic group is the Chhetri (more than 50%), followed by Brahmin (about 20%), Dalits (about 10%), Thakuri (7%), Magar (2 %), and a few other groups. The first two groups are considered privileged and the rest are considered ethnic (Janajati) and disadvantaged (Dalits). Ethnic and disadvantaged groups have easy access opportunities provided by the government.

Field surveys and data collection

Four field surveys were carried out during different seasons of the year (May, December 2006, February 2007, March-April 2008). Each survey lasted over 20 days in the field. Primary data collection, after establishing oral informed consent with the participating communities, consisted of group discussions, informal meetings, schedule surveys, key informant surveys, cross-checking, and field observations. In all surveys, four group discussions and six informal meetings were held; in total 172 individuals were consulted. Informal meetings were held in villages while staying with them. The traditional healers (Baidhyas) and women representing major ethnic groups, castes, and occupations were encouraged to participate. Baidhyas are traditional medicinal practitioners particularly of the western Nepal mid-hills [15] and adjoining areas of India [16]. Women were active participants of the informal meetings. Among the respondents, 3% were traditional healers, 12% were ethnic groups, and 21% were women.

All plant species encountered during field observations were recorded. Medicinal plant species were collected during the day and displayed during evening meetings for discussion. Both the collections and surveys/discussions were facilitated by local assistants, and the information was sought about vernacular dialects, indigenous uses of the species and participants' priority on species. Ranking was followed to categorize the first, second and third priority medicinal plant species. The species enumerated in the present study were the second priority medicinal plants of the local communities with informant consensus factor less than 0.85. The first priority medicinal plants with quantitative ethnomedicine were already discussed [14,17].

Matching information from at least three respondents (mentions) was counted as a common response for the analysis. The single most common folk use of each species was valued for further discussion. Common species and mono specific genera which were well known by their dialect names were used only for discussion and not managed as voucher specimen for further identification. Voucher specimens were collected, and vernacular names and folk uses were recorded for each specimen. Specimen collection was made following Cunningham [18], and plants were identified to species level. Most of the species were identified in the field using literature [19,20]. The remaining unidentified species were identified and housed in Kathmandu at Tribhuvan University Central Herbarium (TUCH), Department of Botany, Tribhuvan University, Nepal.

The observations of the present survey were compared to earlier observations, latest common phytochemical findings and common uses of the Ayurveda. The common uses of the Ayurveda were taken from the following literature [21-27]. Literature [28-33] of Nepal were used as reference for earlier ethnomedicinal information of the same area. Pharmacological information was retrieved from internet sources (available till June, 2010) and relevant journals; most of them were accessed from USA. About 240 research papers and articles were reviewed for analysis.

Results and Discussion

Traditional herbal medicine

Traditional herbal medicine has been used since ancient time in many parts of the world where access to formal and modern healthcare is limited. Nepal is not exempt and in mid-hills, mountainous and rural areas of the country where access and services are limited, herbal medicine is the basis of treatment of most illness through traditional knowledge. It is estimated that approximately 90% of the Nepalese people reside in rural areas where access to government health care facilities is lacking [30]. These people rely predominantly on traditional herbal medicine. Traditional medicine is made available via ancient, natural health care practices such as tribal lore, home herbal remedy, and the Baidhya, Ayurveda and Amchi (traditional healing system of Tibet and mountain areas of Nepal) systems. The former one is innate to the tribal group (i.e. Raute in study area) [34]. Home herbal remedy and the Baidhya system are indigenous to far-west Nepal [14,15] and are partly influenced by the Ayurveda [35]. Extant of home herbal remedy in far-west Nepal is also due to relatively homogenous resource users and less encroachment from immigrants. Home herbal remedy and Baidhya system, yet transformations of the Ayurveda, are well established and practiced in the study area. The Amchi system is widely accepted and practiced throughout high altitude areas of Nepal [10] and is important in Darchula district, albeit with some modifications [29].

As communicated by Kunwar et al. [17], the knowledge base for traditional herbal medicine stems from spirituality, customs, livelihood strategies and available nearby resources. Medicinal herbs are main ingredients of traditional herbal medicine, and the traditional herbal medicine is considered as the main lifeline [36], the first choice [37], fewer side-effects, better patience tolerance, relatively less expense, and cultural acceptance and long history of use, in comparison to western medicine. Thus, the traditional herbal medicine has not only survived but also thrived in the trans-cultural environment with its intermixture of ethnic traditions and beliefs. Most of the time, this knowledge is passed on orally and therefore is endangered. Particularly the Amchi knowledge is passed down through dedicated apprenticeships under the tutelage of senior Amchi [38]. Although traditional herbal medicine is effective in treatment of various ailments with considering ritual and socio-cultural customs [39], very often the medicine is used indigenously with indifference to the scientific knowledge and their possible side effects were overlooked. The dearth of reports of adverse effects and interactions probably reflect a combination of under-reporting and the benign nature of most herbs used [40]. Therefore, the traditional herbal medicine deserves a great scope of research in the light of modern science.

The present assessment showed that traditional herbal medicine has flourished in rural areas where modern medicine is parsimoniously accessed as a result of the high cost and long travel time to health center. Moreover inadequate modern medical resources/facilities and government subsidies also made traditional herbal medicine pertinent in Nepal. It is estimated that there is one physician for every 20,000 people whereas there is more than one healer for every 100 people in Nepal [41,42]. Herbal medicine prescribed by healers is either preparation based on single plant part or a combination of several plant parts. However, we dealt only the primary one for further discussion in the present study. Many of the plants most often used in study area to treat ailments are also commonly used all over Nepal. Particularly the ethnic groups and scheduled caste are the major stakeholders of the traditional herbal medicine [43], so, traditional medicine is still the mainstay of health care in the rural areas of Nepal where the majorities of the denizens are from ethnic groups and scheduled castes.

Medicinal plants and their uses

Of the 48 species from 46 genera and 40 families (Table (Table1)1) discussed in the present study, indigenous uses of about 70% species resembled to the earlier ethnomedicinal reports. The indigenous uses of about 50% species had affinity to the Ayurveda, and about 40% species were found to have efficacy in pharmacology. Fabaceae, Moraceae and Rosaceae were represented by the greatest number of species (3 each), followed by Euphorbiaceae and Lamiaceae (2 each) for herbal medicine in study area. A total of 30 ailments were reported in the present study, and among these inflammation, cuts & wounds, diarrhea & dysentery and fever were considered as common, and the maximum number of medicinal plant species were used against, six species to each category and four for the latter. Similar observation of maximum number of species used for fever and cuts & wounds was reported by Manandhar [34]. The plant parts used for herbal remedies were bark, flower, fruit, leaf, milk/latex, root/rhizome, seed, shoot, wood, and the whole plant. Plant parts root/rhizome, leaf, and fruits, etc. were most frequently utilized.

Pharmacology

The results obtained support prior observations, pharmacology and Ayurvedic uses concerning the following species: the crude extracts of Acacia catechu for cold and cough, Aconitum spicatum as analgesic, Aesculus indica for joint pain, Andrographis paniculata for fever, Anisomeles indica for urinary affections, Azadirachta indica for fever, Euphorbia hirta for asthma, Taxus wallichiana for tumor control, and Tinospora sinensis for diabetes. This probably explains the use of these plants by indigenous people against a number of infections as transcend from transcultural environment with following home herbal remedy, Ayurveda and Baidhya systems. It is known that the families Rutaceae and Meliaceae are among the richest and most diverse sources of secondary metabolites among the angiosperms [44], and the species of Meliaceae are known to have intense antimalarial characters due to highly oxygenated terpenoids [45]. Use of leaves of Azadirachta indica (Meliaceae) as antipyretic is widely used in study area (Table (Table1)1) and throughout Nepal [46] was substantiated by the nimbidin flavonoids [47,48]. Oleic acid and gedunin of A. indica are also reported to be an in vitro antimalarial [49-51]. Other species contributed as antipyretic in home herbal remedy in study area were Andrographis paniculata (Acanthaceae), Aconitum spicatum (Ranunculaceae) and Osmanthes fragrans (Oleaceae).

Andrographolide and neoandrographolide from Andrographis paniculata own anti-inflammatory activity [52,53]. Its diterpene exhibits antioxidant and hepato-protective properties [54-57]. Immunostimulant [58], antibacterial [59], analgesic [60] and antiprotozoal [61] characteristics of A. paniculata extract have also been demonstrated. These values probably explain the use of A. paniculata by the indigenous people against a number of infections and fever. Crude root extract of Podophyllum hexandrum (Berberidaceae) was used as hepato-protective, despite the hepatotoxic character reported due to its lignans [62]. Podophyllotoxin has manifested antimitotic activity and capability of inhibiting DNA, RNA and protein synthesis [63]. There were seven species in study area exhibiting hepato-protective effects. Among them, six were pharmacology based and three were folkloric. Plant extracts of P. hexandrum and Andrographis paniculata showed hepato-protective characters consistent with the folk use and pharmacology.

Alkaloids are most common in flowering plants, especially in Fabaceae, Ranunculaceae and Solanaceae [64]. Some alkaloids (aconitine, anisodamine, berberine, charantine, leurosine) show antidiabetic effects [65]. Berberine of Tinospora sinensis (Menispermaceae) is antidiabetic [66-68], but higher doses may be antagonistic [69], which strongly support the folkloric use of the plant extract. According to Marles and Farnsworth [70], there are about 1,000 species of plants that can act as an antidiabetic and approximately 80% of these are used in folk herbal medicine. Antidiabetic reports of Azadirachta indica, Carum carvi, Tinospora sinensis and Vitex negundo stated in the present communication were pharmacologically rationale and that of A. indica and T. sinensis was folk-based.

Euphorbiaceae species are generally characterized by milky latex [71], and sticky saps are co-carcinogenic, and can cause severe skin irritation and are toxic to livestock and humans [72]. They are rich in active compounds including terpenoids, alkaloids, phenolics and fatty acids, having ethnopharmaceutical uses [73]. Sapium insigne (Euphorbiaceae) is skin irritant, and commonly used as fish poison in study area and throughout Nepal [28]. Both the water and methanol extracts of Euphorbia hirta (Euphorbiaceae) are antibacterial [74,75] and effective as expectorant [76,77] and broncho-dilator [27], which is consistent with the folkloric use in treatment of respiratory complaints.

Pharmacologically, curcumin of Curcuma species (Zingiberaceae) acts as an anti-inflammatory [78-80], antibacterial [81], antiviral [82], antifungal [83], antitumor [84,85], antispasmodic [86], and hepato-protective [87]. The oxygen radical scavenging activity of curcumin has been implicated in its anti-inflammatory effects [88,89] thus curcumin may prove useful as a drug for arthritis, cancer, HIV [90-92] and high blood pressure [93]. Wide range of pharmacological reports including antibacterial and antiviral complements the folk use to treat paralysis. Rhizome extract of the plant was widely used for skin diseases (bruises, injuries, etc.) in west Nepal [15] and in the Ayurveda [21].

The folk use of Acacia catechu (Fabaceae) wood tea as an expectorant fairly corroborated the pharmacological properties because the tannin and cyanidanol [94,95] of the plant impart astringent activity which helps to recuperate diarrhea. Tannins are also known as antimicrobial [96] and triterpenoids are beneficial for inflammation and cancer [97]. The hepato-protective and hypoglycemic properties of A. catechu could be attributed to the quercetin [98] and epicatechin [99] respectively. Leaf extracts of Taxus wallichiana (Taxaceae) inhibit pregnancy in rats [22], vitiate blood disorders [100] and control tumor growth [101]. In the study area, Taxus leaf juice is used for treatment of cancer and bronchitis.

Lectins of Cannabis sativa (Cannabaceae) possess haema-gluttinating properties [38] which corroborate the indigenous use of the leaf extract to control bleeding. Crude leaf extract of Vitex negundo (Verbenaceae) is recommended as antitussive and anti-asthma [102], antibacterial [103], antifungal [104], hypoglycemic [105], anti-cancer [106], acne control [107], inhibitor of edema [108,109] to tracheal contraction [110]. However, it did not corroborate the folk use for stomachache but was partially complemented by earlier observations [30,111]. The unlike uses of the species after thorough scrutiny, under different medical systems and comparisons pose more research scopes. Several instances are rational behind a certain function of a phytomolecule sometimes inconsistent to the pharmacology and ethnopharmacology. Moreover, while advocating herbal medicine as alternative therapy, toxicity of plants should be borne in mind.

Lichens and their metabolites have manifold biological activity: antiviral, antibiotic [112], antitumor, allergenic, plant growth inhibitory, antiherbivore, ecological roles and enzyme inhibitory [113,114]. Usnic acid and vulpunic acid (produced by mycobiont) of lichens are mitotic regulators [115] and own antibiotic properties [116]. Parmelia sulcata lichen manifests antibacterial and antifungal activities [117,118]. Use of Parmelia species to treat warts [119] is analogous to its folk use. Folk use of wood tea of Quercus lanata (Fagaceae) as a laxative may verify the actions of tannin. Tannins reveal activities against central nervous system disorders [120] and inflammation [121,122]. Further pharmacological evaluation of the extracts of those species which reveal weak pharmacological validities are needed before they can be used as therapeutic potentials.

The compounds which contribute to the antioxidative properties are polyphenols [123], vitamin C [124], β carotene [125], anthocyanins [126], and flavonoids [127]. Ellagic acid of Fragaria nubicola (Rosaceae) is also responsible for antioxidant activity [128]. Antioxidants are associated with reduced risk of cancer and cardiovascular diseases [129] and many other ailments [130]. Antimicrobial and anti-inflammatory properties of Fragaria fruit extracts [101,131] are consistent with the folkloric use as remedy for skin diseases and wounds. The usage of root powder of Potentilla fulgens (Rosaceae) as a dentifrice is common in the study area and throughout Nepal [132,133] and it is in accord to the Ayurvedic uses. However, the usage is yet to be verified pharmacologically.

Wogonin of Scutellaria discolor (Lamiaceae) is considered as a most potent antiviral [134] and anxiolytic [135] compound. Plant root extract is also useful for rheumatism [136]. Whole plant and leaf paste is useful for cuts & wounds, which probably rationalize the activities of wogonin. Linalool also possesses an anxiolytic effect [137], and this effect probably substantiates the folk uses of Skimmia anquetilia (Rutaceae) leaves as medicine for headache and freshness. Linalool is the main constituent of Skimmia root. The indigenous uses of six species Arisaema flavum, Ficus religiosa, Rhododendron campanulatum (Figure (Figure2),2), Smilax aspera, Solena heterophylla and Sterculia villosa repudiated to any of the comparables, since these uses were additional to the Nepalese ethnomedicinal vault and these addition demands further research.

Figure 2

Aconitum spicatum (Ranunculaceae), taken alone is poisonous, so it is never used alone by the local communities. A paste made from its roots is applied as antipyretic and analgesic after mixing with Terminalia chebula (Combretaceae). Folk use of root extract of A. spicatum as an analgesic is consistent to the anti-inflammatory activity of caffeic acid found in the plant extract [138]. About 80% of plant alkaloids possesses anti-inflammatory properties and among them isoquinoline (berbamine, berberine, cepharanthine and tetrandine) was the most active [139,140]). Diterpenoid alkaloids, commonly isolated from the plants of Ranunculaceae family, are commonly found to have antimicrobial properties [141]. Folk uses as antipyretic and analgesic of A. spicatum root extract are validated by the in vitro antimicrobial properties. In some cases, multi-component therapy has been practiced and considered as effective as Kareru et al. [142] observed in Kenya, but the present assessment considered only the primary one to discuss. We believe that the associate plants must also be considered as excellent candidates for future studies to determine the mechanisms of their activity, as well as for the isolation and identification of active constituents [143,144]. Thus, traditional herbal medicine renders primary health care needs of two thirds of the rural population of the Nepalese, represents a largely unexplored source for potential development of new drugs [145,146].

Conclusions

Validation of the ethnomedicinal uses of 48 Nepalese medicinal plants using comparative assessment with the common uses of the Ayurveda, earlier studies and the latest phytochemical findings showed that the folk uses of only about 50%, 70% and 40% of plant species respectively exhibited affinity. The folk uses of Acacia catechu for cold and cough, Aconitum spicatum as an analgesic, Aesculus indica for joint pain, Andrographis paniculata for fever, Anisomeles indica for urinary affections, Azadirachta indica for fever, Euphorbia hirta for asthma, Taxus wallichiana for tumor control, and Tinospora sinensis for diabetes are consistent with the latest pharmacological findings, as well as common Ayurvedic and earlier uses. However, the frequent folk uses of Arisaema flavum, Ficus religiosa, Rhododendron campanulatum, Smilax aspera, Solena heterophylla and Sterculia villosa of study area repudiated at all. The preliminary results obtained from the present assessment indicate that further investigation of ethnopharmacology is worthwhile. The validity assessment from the present research provided the potential to identify, research, and use which plants and their ingredients are the most significant for treatment of particular diseases.
