Does Tulsi has environmental benefits too?

Recently there was a news item in Times of India which had the same heading as that of this particular post. The news claimed

(Around two decades back Dada Dham, a socio-spiritual organization brought together a team of botanists, ayurvedic scholars and environmental enthusiasts to study the environmental benefits of tulsi.)

NAGPUR: Ayurvedic medicinal values of Tulsi are well known. Our ancient scriptures have enumerated the medicinal benefits of tulsi. Its extracts are used widely for curing common ailments like common cold, headache, stomach disorder etc.
But the environmental benefits have been comparatively unknown. Around two decades back Dada Dham, a socio-spiritual organization brought together a team of botanists, ayurvedic scholars and environmental enthusiasts to study the environmental benefits of tulsi.

Now the next claim from an “eminent botanist” that the report does is startling indeed.

“Tulsi gives out oxygen for 20 hours and ozone for four hours a day along with the formation of nascent oxygen which absorbs harmful gases like carbon monoxide, carbon dioxide and sulphur dioxide from the environment,” said Shyamkant Padoley, an eminent botanist.

How would the tulsi plant (Ocimum tenuiflorum) do this? Is it anatomically so different that it is capable to do this? How does the plant regulate this 20 and 4 hour cycle? I would really like to know. How is that no other plants have this cycle? How did they detect presence of ozone, what detectors they used? What mechanisms in presently known cycle of photosynthesis account for this cycle? And if this is part of the standard photosynthesis process, then all plants should have it. This seems fishy, and a most preliminary search did not yield any positive result. All of them talk about production of oxygen and not ozone, as reported by Padoley. And if this is indeed true, it might lead to change in our conception of the photosynthetic cycle.

And if the ozone report is to be believed at all then this is what ozone does to you quote from Wikipedia article on ozone:

Ozone is a powerful oxidant (far more so than dioxygen) and has many industrial and consumer applications related to oxidation. This same high oxidizing potential, however, causes ozone to damage mucus and respiratory tissues in animals, and also tissues in plants, above concentrations of about 100 parts per billion. This makes ozone a potent respiratory hazard and pollutant near ground level.

…

There is evidence of significant reduction in agricultural yields because of increased ground-level ozone and pollution which interferes with photosynthesis and stunts overall growth of some plant species. The United States Environmental Protection Agency is proposing a secondary regulation to reduce crop damage, in addition to the primary regulation designed for the protection of human health.

…

There is a great deal of evidence to show that ground level ozone can harm lung function and irritate the respiratory system.Exposure to ozone and the pollutants that produce it is linked to premature death, asthma, bronchitis, heart attack, and other cardiopulmonary problems.

…

Ozone is air pollutant, green house gas.

To summarize this is that ozone is NOT GOOD for us at ground level! It may do us good in upper atmosphere to block UV Rays, but down here on ground it is bad. And if this claim of ozone production by Tulsi is true why is the campaign of “Tulsi lagao pradushan hatoa (Plant tulsi, remove pollution)” which follows in the article is being implemented?

Padoley, member of technical committee, ministry of environment and forest, NewDelhi, and forest tech committee, also read a paper at the International Conference on Occupational Respiratory Diseases at Kyoto in 1997 where cyclo oxygenate, an enzyme only found in tulsi was labelled for the first time. This enzyme regulates the entire mechanism of oxygen evolution. (emphasis added)

This again I am unable to understand. It says this enzyme is “only found in Tulsi”, and it also “regulates entire mechanism of oxygen evolution”. One can agree that a particular enzyme is found in a particular plant, but if this enzyme controls “entire mechanism of oxygen evolution”, how do other plants regulate their mechanisms of oxygen evolution.

Dada Dham initiated a campaign ‘Tulsi Lagao Pradushan Hatao’ in 1987 under the guidance of Narendra Dada, the institution’s head. It was under this campaign that the above mentioned panel of experts was formed. After finding out the environmental benefits of the plant, Dada Dham organized a number of programmes like street plays, nukkad sabhas and lectures to propagate the use of the plant.

Dr Dattatraya Saraf, an ayurvedic doctor and expert said, “The plant enriches the environment with oxygen almost 24X7 and also absorbs other pollutants.” He further added that if the size of the plant can be increased, the environmental benefits can be increased.

This statement that “plant enriches the environment with oxygen almost 24X7” is in contradiction to statement by above Padoley regarding 20 and 4 hour cycles. Which one is to be believed? And mind you this is just appearing a few lines later, this is either very poor editing and reporting, or hogwash to the public.

“That is why we want to urge scientists and concerned authorities to make research on the issue of increasing the height of tulsi plant. If big trees can be converted to bonsai plants then big tulsi trees can be possible too,” said Kishor Verma, PRO of Dada Dham.

This is another statement that I would like to contest. Did they compare the rate of oxygen production vis-a-vis to other plants. That is to say simply did they have any control sample? And does making “tulsi tree” make any sense (can one really do it is another question), will it really increase oxygen making capabilities, is it a linear relationship between these two variables? The water is completely muddy in this !

He also citied the research and work by other organization in support of tulsi’s environmental benefits.
“The forest department of Uttar Pradesh, with the help of an organization called Organic India Limited, Lucknow planted lakhs of tulsi saplings around Taj Mahal to protect its surface from industrial emissions. This step has yielded positive results,” Verma said.
“We are just asking the administration to take notice of these extra ordinary benefits of tulsi and take steps for utilizing them. Even simple steps like planting tulsi plants on road dividers, parks etc can bring a difference,” said Verma.

The reporter and also the editor make no effort to correct these glaring inconsistencies in the report itself, forget about doing nay research on the topic, or verifying the claims made by these people. Maybe this was like the paid news that is talked about a lot these days.
What I find here i that the agenda of what is to be done was already set, the conclusions were already drawn, by our ancestors, written in black and white in ancient texts. The point was only to justify what they were doing, and trying to provide a “scientific basis” of what they already believed to be true (for whatever reasons, mostly religious, and presence of a religious organization in this sort of confirms this).
A good example of pseudo-science and bad science reporting.

Science, a humanistic approach

Science is an adventure of the whole human race to learn to live in and perhaps to love the universe in which they are. To be a part of it is to understand, to understand oneself, to begin to feel that there is a capacity within man far beyond what he felt he had, of an infinite extension of human possibilities . . .
I propose that science be taught at whatever level, from the lowest to the highest, in the humanistic way. It should be taught with a certain historical understanding , with a certain philosophical understanding , with a social understanding and a human understanding in the sense of the biography, the nature of the people who made this construction, the triumphs, the trials, the tribulations.

RMS on Success

“Success” is not our goal; we’re not here to win a race, we are here to win freedom. I didn’t write GCC with the idea of making a “better” C compiler. I wrote it so there would be a freedom-respecting C compiler, and while I was at it, I did the best job I knew how. We didn’t develop GNU to have a “better” operating system than Unix; we developed it so we could have a freedom-respecting operating system. It’s the same today.

Computers in Teaching and Learning

The question of whether a computer should be used in teaching and
learning, is no more interesting than the question whether a book
should be used for reading.
The interesting question is of how to use the computer to teach and
learn, and how not to use it to teach and learn.

CURE Logo

In earlier post we had seen the CUBE Logo, now in this post we will see, CURE Logo. CURE stands for a cure of problems of CUBE and is Collaborative Undergraduate Research and Education. The idea is to propagate the spirit and activities via making many-many centres across India and when one centre gets the know-how, it starts acting as a centre itself. This has enormous potential and is also not so easy, if we are planning to form a network of 20,000 odd colleges across India. Hats off to this initiative by Dr. M. C. Arunan.
Since the idea was to propagate the via forming numerous nodes, and absence of a centralized structure, we came up with the Pythagorean Tree as one of the possible candidates for the logo. The Pythagorean Tree is a fractal structure which is self similar. This also reflects the spirit of CURE and CUBE, that the size of the institute or its location should not reflect on the facilities or the opportunities that it provides to its students.
In this program an initial batch of students , lets call them Batch-0 is trained for performing a series of experiments . At end of their training which is a hands on, they give a talk on their work. In the next step, these students build these facilities at their alma mater and maintain them. This is the first iteration of the program. After this iteration, the Batch-0 students, who have handled these biological systems for some time now and carried out some investigations become mentors for the next batch of students. Lets call these as Batch-1. Now we conduct another session of training, in this the Batch-0 students act as mentors for Batch-1 students. Thus at end of this training another iteration of the programme is completed. So the second iteration builds on the first one. Then for the Batch-2 students, the students from earlier batches act as mentors, thus at each stage we are increasing the mentors as well as the facilities available for doing research. Iteratively, collaboratively we can sure reach the 20,000 odd under-graduate colleges in India

In the logo the base triangle forms the basis of all the structure, this we call as Batch-0, and rest of all others are based on this. And since this is an iterative, self-similar figure, none of them are different from one another, neither are the squares different. For example the small branch sitting on top of the large branch is a similar to the larger branch. If we scale it. it would be the same.

Lack of research facilities at the undergraduate level , is most often cited as cause for poor education at that level. And the facilities come expensive. This was we can make in-expensive or some times zero-expense facilities for college education and get the students involved. This logo is released under Creative Commons Share Alike License.

The Illusion Of Democracy

But, of course, corporate media professionals have long propped up the illusion that the public is offered an ‘impartial’ selection of facts, opinions and perspectives from which any individual can derive a well-informed world view. Simply put, ‘impartiality’ is what the establishment says is impartial.
The major political parties offer no real choice. They all represent essentially the same interests crushing any moves towards meaningful public participation in the shaping of policy; or towards genuine concern for all members of society, particularly the weak and the vulnerable.
US media analyst Robert McChesney observes:

‘In many respects we now live in a society that is only formally democratic, as the great mass of citizens have minimal say on the major public issues of the day, and such issues are scarcely debated at all in any meaningful sense in the electoral arena.’ (McChesney, Rich Media, Poor Democracy, The New Press, 2000, p. 260).

Elites And Us

The longer this worldwide disparity and inequality is perpetuated, the more the masses will revolt and the faster we will internally replicate the Israeli model of domestic control – drones overhead, all dissent criminalized, SWAT teams busting through doors, deadly force as an acceptable form of subjugation, food used as a weapon, and constant surveillance.

Love, personal qualities and infection

She said: “It seems to me that everyone has a quality that can get the better of love. Is stronger, you see. Like pride. Or honesty. Or moral – even intellectual, even emotional – integrity. Take two people in love. The only thing that can really upset things is this personal quality in one of them. Other people don’t come into it at all. Except in a roundabout way – as intruments of jealousy, for instance. Don’t you agree?”
I wasn’t sure about anything, but I said yes.
“Another thing about love,” the girl with ringlets said, “is its extraordinary infection. Has it ever occured to you that when you’re in love with someone you’re really wanting to be loved yourself? Because that, of course is the natural law. I mean, it would be odd if every time one person loved another person the first person wasn’t loved in return. There’s only a very tiny percentage of that kind of thing.”
