Panax pseudoginseng Wall. Family Araliaceae is a very rare 30-60 cm tall erect herb distributed in the interior temperate mountainous regions of Sikkim, Bhutan, Nepal and China, recorded in the Western Himalayas from Pithoragarh district in Uttar Pradesh.
The root of Asian ginseng contains active chemical components called ginsenosides (or panaxosides) that are thought to be responsible for the herb's medicinal properties. The root is dried and used to make tablets or capsules, extracts, and teas, as well as creams or other preparations for external use.

The North Sea was once isolated from surrounding oceans and its change to a more fresh water state led to a significant reduction in the diversity of life, say a team of German and British scientists who have used fossilized shark teeth to reconstruct the climate of the North Sea during the Palaeogene period, between 40 and 60 million years ago.
The Palaeogene was a time when greenhouse conditions prevailed and mammals began to diversify in the wake of the mass extinction event that saw the demise of the dinosaurs, along with 65% of all species.
The state of Rajasthan is situated between 23º3’ and 30º12’ N latitude and 69º30’ and 78º17’ E longitude . The total land area of the state is about 3,24,239 km² , out of which about 1,98,100 km² is arid and rest is semi arid. The physical features are characterized mainly by the Aravallis and to the some extent by the vindhyan formation, and the Deccan trap. A major portion of western Rajasthan has desert soils and sandy plain. Sand dunes occupy a greater part of western Rajasthan ( 1,20, 983 km²). The soils of the desert plains are loamy sand to loam and eastern part has alluvial soil which support good forests and agricultural crop. Occurrence of saline soils with pH up to 9.0 is a common feature in sandy area of Rajasthan.
On the big list of environmental challenges we face, you might worry about volcanic ash or industrial soot or farting cows ... some people are even concerned by an obscure greenhouse gas named carbon dioxide. But you probably aren't concerned about the global impact of those rare rocket launches.
Going green is big, though, so efforts to make green rocket propellant are getting funding. Thus, NASA and the Air Force Office of Scientific Research are pleased to accounce they have successfully launched a small rocket using an environmentally-friendly, safe propellant comprised of aluminum powder and water ice, called ALICE.
When Earth was cooling from its fiery creation, the sun was faint and young, far too weak to keep the oceans of earth from freezing without some help from greenhouse gases; they kept water, essential for the creation of life, liquid on our young planet.
But what were they? A team of researchers from Tokyo Institute of Technology and University of Copenhagen's department of chemistry say ancient rocks have provided a possible answer, and they report the results in PNAS.
"The young sun was approximately 30 percent weaker than it is now, and the only way to prevent earth from turning into a massive snowball was a healthy helping of greenhouse gas," says associate Professor Matthew S. Johnson of the Department of Chemistry at University of Copenhagen.
One of the biggest mistakes environmentally conscious people make is thinking that an 'organic' pesticide is somehow superior to an inorganic one. The word 'organic' may be the most misunderstood word in western Civilization because there is no structural difference in complex, carbon-based molecules whether they were created in a lab or on a tree.
Nature understands exactly what organic means, including what pesticides are designed to do. Whether or not a small group of people consider them organic is irrelevant - you won't want to eat food treated with Pyrethrin even though it is considered completely 'organic', for example.
But marketing wins big battles so people want foods produced in more natural ways - enter rosemary, thyme, clove, and mint.
British start-up Novacem has developed a "carbon-negative" cement, meaning it absorbs more carbon dioxide over its life cycle than it emits.
Cement is a big ol' polluter - with an annual production of more than 2.5 billion tons, Reuters says
, conventional "Portland" cement is responsible for an estimated 5 percent of global CO2
emissions, more than the airline industry.
Treelines are not responding to global warming the way previous projections said they should, according to the first global quantitative assessment of the relationship between warming and treeline advance published in Ecology Letters.
The study tests the consensus that treelines have been globally advancing in response to the warming climate since 1900.
A new process that cleans wastewater, generates electricity, and can remove 90 percent of salt from brackish water or seawater, was reported by an international team of researchers from China and the U.S.
Clean water for drinking, washing, and industrial uses is a scarce resource in some parts of the world. Its availability in the future will be even more problematic. Many locations already desalinate water using either a reverse osmosis process -- one that pushes water under high pressure through membranes that allow water to pass but not salt -- or an electrodialysis process that uses electricity to draw salt ions out of water through a membrane. Both methods require large amounts of energy.
