The Nobel prize winning root of Japan

It is a plant called Wasabi which is extensively cultivated in the stream beds of mountain river valleys in  Japan, Tasmania, Hawaii and Oregon. The root of this plant is light green in color and resembles ginger. It is very nutritious and hence grated and used in Japanese cuisine. 



Japan takes the privilege of planting Wasabi for the first time. In the 10th Century AD, Japan cultivated Wasabi and introduced it to the rest of the world. Growing Wasabi is not only a difficult task but time-consuming too as the roots take a minimum of two years’ time to become fully developed. 

Hence, purchasing wasabi proves to be very expensive. The grated stems and leaves are widely used in Japanese Sushi and Salad recipes.

Wasabi’s most significant characteristic is the strong pungency. Once the stem is grated, it has to be consumed within 15 minutes; else it loses the flavor. So, the Japanese grate the stem and preserve the paste in ready-to-use tubes. Its hotness equals that of chili pepper and creates vapors that stimulate the nasal passage. The burning sensation of wasabi is short-lived compared to the hotness of chili but a bit of overdose may be quite painful. 

Wasabi has natural healing properties similar to all Indian herbs. It eradicates cancerous cells, reduces the effect of allergy, asthma and bone deficiencies and also controls blood clotting thus preventing paralysis and heart ailment.

Now we are still eager to learn, how did wasabi win a Nobel Prize ? If there is fire or smoke, the smoke alarm goes off so that we can run to safety. But, How do you wake a deaf person in the middle of the night if there's a fire?  Japanese scientists have come up with a new type of alarm which squirts the essence of wasabi whose pungent smell makes the person run away from it.  This lifesaving piece of work won the Japanese Researchers the award of the Nobel prize for chemistry.
