Medicinal plants, herbal remedies
Lorestan is one of the provinces which is capable of planting medicinal
plants because of topographic conditions. Availability of these
medicinal plants in the country and the province has increased grounds
for production and even export of these plants. Today, most reputable
pharmaceutical companies in different countries use medicinal plants for
the production of drugs which is evidence of the importance of such
plants.Due to the geographical and specific climatic conditions of Iran,
Lorestan Province holds a valuable position in the production of a
variety of herbs and medicinal plants. Different climatic conditions in
Iran has caused medicinal and pharmaceutical plants to grow so that
Zagros region, in which Lorestan is Located, has become the habitat of
diverse species of forest and grassland products.
To study the medicinal plants, two characteristics of the province have to be taken into account:
First, the old history of human life in the region which indicates that
using medicinal plants has the same long history. Second, the specific
climate and weather conditions of the region has made the province a
rich habitat for such plants. For example, Hoseinieh in Poldokhtar, in
the south of Lorestan, has the minimum altitude of 350 m and
Oshterankooh, Doroud has the maximum altitude of 4050 m.
This difference of 3700 m in altitude has made the province to be the
home of a large variety of plants with different characteristics. Being
at the intersection of several weather fronts namely the Black Sea and
the Mediterranean from west, the Indian Ocean from east, the Red Sea
from south, has made Zagros region a unique ecotom in the world which is
home to unique species of flora and fauna. Lorestan is located at the
heart of such exquisite nature, i.e., central Zagros.
There are more than 1200 species of plants in Iran 167 of which have
been identified. Of these, 27 species are indigenous to Lorestan. The
area under cultivationfor medicinal plants in the province is 357
hectares, of which 4150 tons of medicinal plant is produced.
Of the eight thousand plant species in the world,2500 species are
medicinal plants and native to the province. This natural diversity has
also contributed to production variety in the region.
The most medicinal plants in Lorestan include chamomile, artichoke,
mint, fennel, chicory, lemon balm, Musk willow, coriander, cumin,
savory, anise, sesame, fumaria, anemone, sisymbriumirio, borage, yayty
cave, licorice, marshmallow, five digits, marianum, shnblyh, grass,
knotweed, about, sage and parsley, while some species such as anshk, and
savory are indigenous to Lorestan. Meanwhile, these plants have been
distributed in different cities of lorestan including Aligudarz,
Kuhdasht, Khorramabad, Poldokhtar, Chegeni, Delfan and Selsele.
It is worth mentioning that 5000dug products are originated from plants.
In our country, only 10% of drugs are of plants origin; 90% are
produced using chemicals. Besides the use of medicinal plants for
chemical products, the plants, themselves, can be used to treat
diseases. For example, mountainsavoryis effective in the treatment of
blood pressure and blood lipid.Some other plants are effective in the
treatment of skin and mucosa diseases, and bronchitis.
Mint is also effective in the treatment of infectious and digestive
diseases as well as and urinary tract. These are, of course, but a few
benefits of medicinal plants. According to natural and supplementary
drugs department of the Ministry of Health, treatment and Medical
Education, more than 700 plant products have been patented as medicinal
and are now used for diseases treatment. Additionally, more than 1/3 of
the drugs used by human being is of plant origin and this amount is
increasing. According to WHO, the proportion of using medicinal plants,
compared to chemical plants, is 15 to 3 which contributes to the
international financial balance of these drugs.Although the marketing of
pharmaceutical plants such as, Gaz, tragacanth, thyme, celery, radish,
marshmallow, cam and other edible plants are national, some other plants
such as turpentine, galbanum, kapparis and grasses borage are exported
to Asian and European countries.
Finally, the climatic diversity coupled with mountains and special
plantation productivity in Lorestan and current capabilities can make
the province the hub of medicinal plants production and provide job
opportunities for graduates of agriculture majors.
