WEEDS AND MEDICINAL PLANTS OF SHAWAR VALLEY, DISTRICT SWAT
Shawar valley located on 350 07’ to 350 22’N and 720, 29’ to 720 39’E was analyzed for weeds as will as medicinal plants. There are 49 weed plants, out of 49 weeds 30 plants are used as traditional medicines. Among these, 37 are herbs, 06 are shrubs, 03 are trees and 03 are climbers. In the primary health care these folk medicinal plants have significant role for the inhabitants of Shawar valley. Especially the people who can not afford allopathic drugs are tempted to use of such medicinal plants.
Key Words: Medicinal value, ethnobotany, Northwest Frontier Province.
The valley of Shawar lies in District Swat, Tehsil Matta in the Hindu Raj Mountains. It can be traced at 350 07’to 350 22’ and 720, 29’ to 720, 39’ North latitude and East longitude, respectively (Pers. Comm. Department of Geography, University of Peshawar, Pakistan). The total area of the valley is 4877 ha, while the total population of the valley is 20,163. Literacy rate is 12.6%; male and female education at Matric level is 200 and 13 individuals, respectively. The valley comes under the Sino Japanese Region (Ali and Qaisar, 1986; and Robert et al., 1995). Geography of the valley also shows that in the West it is bounded by Niage Dara (Dir), in the North by Dir Kohistan, in the Northeast by Beha valley. Totano Banday and Mian Kalay Biakand in the South of Tehsil Kabal and Tehsil Matta, respectively.
The valley comprises gently rolling topography in its Northern, Southern and Western side. Southern hilly areas are gently sloping while the Northern part moderately goes to high elevation. Precipitation is in the form of rain, monsoon in summer and heavy snowfall in winter. The area establishes west Himalayan moist types of forests (Beg and Khan, 1974). The valley has Oak, Blue Pine, Fir and Spruce forests.
Its highest peak in the North is Landay Sir and Chota Sir having an altitude of 2900 m and 3900 m above sea level, respectively while mean altitude of the plain area is 1400m. Majority of the people residing in the area are Yousafzai Pukhtoon associated with very limited population of Sayed, Molla Khail and the hilly areas are inhabited by Gojer Khail. Ninety-five percent (95%) people are involved in agriculture, horticulture and cultivate their own farms while other five percent (5%) are working aboard in the Middle Eastern countries.
Ethnobotanically, valley is rich in medicinal plants and most of the people are using these plants as a primary source of health care. Among these medicinal plants Acorus calamus used as stimulant, emetic, carminative and as expectorant. Similarly Adatoda vasica, Dioscorea deltoidea and Xantoxylum armatum are used for different diseases (Ur-Rahman, 1999; 2000; 2001). Hedra helix is common liana plant and its leaves contain chromium, zinc and manganese which are hypoglycemic trace elements, is reputed as a folk hypoglycemic medicinal plant. It is also known that aqueous extract of Hedra helix L. has significantly lowered the blood glucose level of alloxan_induced diabetic rabbits and also plays an important role in blood metabolism (Ibrar, 1998; 2000). Annually a large number of medicinal plants are harvested and bought by the local shopkeepers of the valley.
MATERIALS AND METHODS
Geographical information was obtained from the Department of Geography, University of Peshawar. For plant collection, cutter, newspaper, vasculum, and altimeter were taken. Plants were collected, pressed in newspapers with the help of plant presser. On the spot, local name, locality and date of collection were written. Papers were changed from time to time to absorb water from plants. Plants were transferred to herbarium sheets of standard size 14// and 16//. Plants were identified from the flora of Pakistan.
For knowing the ethnobotanical profile of the people, a questionnaire was developed and filled through interview randomly through different walks of life i.e. farmers, Shop keepers involved in medicinal plants business, Hakims and elders of the area. With the help of questionnaire, plant uses and the indigenous knowledge regarding the traditional uses of plants was collected. The knowledge thus extracted from local people regarding their medicinal value has been tabulated in Table-1.
RESULTS AND DISCUSSION
Present study is based on 49 species among which 30 are medicinal plants, 25 are medicinal as well as weeds and 19 are purely weeds belonging to different families and representing Dicot, Monocot and Pteridophytes. Depending upon plant habit, they were broadly divided into herbs, shrubs and trees.
Among herbs are Acorus calmus, Adiantum capillis veneris, Ajuga bracteosa, Ajuga parviflora, Cannabis sativa, Mentha longifolia, Paeonia emodi, Plantago major, Polygonum plebejum, Rumex hastatus , Sorghum halepense, Thymus vulgaris, and Cannabis sativa while Zantoxylum armatum a shrub.
Tree species consist of Ailanthus altissima, Pistacia integerima, Ficus carica, Juglans regia and Zizyphus sativa Gaertn while one species of Adiantum capillus venesis belongs to Pteridophytes.
Ethnobotanically some of the species reported here have multiple uses e.g the delicious nuts of walnuts are edible, also used in culinary preparation, fruits are mental tonic and also used as sexual tonic. Leaves and bark used for teeth cleaning, flowers are used as antiseptic while bark is used in tea factory for tea processing as dying agent. Similarly Berberis lycium is used for jaundice, cooling agent, used for ulcer, colic, aphrodisiac and its fruits are used by children as sour food, hedge plant and used as fuel plants. So plants are natural custodian natural chemical compound and used for multi purposes (Table-1).
