Dear sirs:
I have come across some portions in our Vedas which throw quite
a lot of information on Ethnopharmacology. Many of the plants used
for various rites invariably possess medicinal properties .
For instance, Asvattah tree ( botanical name is Ficus religiosa ) is mentioned
in Taittiriya Brahmana 1-1-3 in the following terms : " Agni wished to hide
from Devas. He took the form of horse and resided in a Peepal tree for one
year. Thus came the name Asvattha for this tree ." Recently Rabideau has
pointed out in an article which appeared in American Journal of Botany
that in the leaves of Ficus species the absorption of incident light is 80-90%
and reflection is 10-20 %, whereas in other species which they examined,
the absorption of light varied between 20-60 %. Thus the Peepal tree
performs the photosynthesis to a degree which surpasses many other trees
and in this way, the environs of Peepal tree are enriched with oxygen
and the content of CO2 is reduced. Therefore people who live under this
tree live longer with good health. The Rishis praised the tree as the ojas
of the wind god.
It has potential to cure many diseases including diabetes and cancer.
It can reduce the poisonous effects of various toxic substances. The
tree contains alkaloids which are biologically active. The extract of bark
relaxes the intestines and aids digestion.
I have come across some interesting references with regard to Arkah plant
and its botanical name is Calotropis gigantea. By its very name it is
related to Sun god. On Ratha Saptami day, we use it. We use it for
Ganesa puja. Arkah is used in Satarudriya homa.
The milky juice obtained from Arkah is poisonous and the latex contains
cardiac poisons. Compositions made out of the leaves are used as herbicides
for control of parthenium grass. A tincture of the leaves is used in the
treatment of intermittent fevers. Colds, coughs, asthma , dysentry are
treated with this plant and its various parts.
It is said that " in addition to its medicinal uses, It has some unexpected
use. The plant yields petroleum ether extract rich in hydrocarbons. These
hydrocarbons are most promising as liquid fuels. These high-molecular
weight compounds can be hydrocracked to yield gasoline,diesel oil and
lubricants. The residual biomass can be utilized to get briquetted fuel,
biogas and fertilizer. " ( D.K.Sharma and C.R.Babu- Fuel science and
technology )
There are many more.
This topic can be shifted to some other thread, if necessary.
