Traditional Medicine Finally Gets Nobel Nod

By



Traditional medicine has got its biggest stamp of approval from the scientific community up until now, with one of its practitioners finally getting the Nobel Prize for medicine in 2015.

Dr. Tu Youyou, the 84 years old lady scientist from China who introduced the anti-malarial properties of extracts of a plant (sweet wormwood) to modern medicine, is the recipient of this year's prestigious prize. Artemisinin, the compound that she extracted and discovered, is currently the most favoured and safest anti-malarial drug used worldwide, and has saved millions of lives from malaria.

The story of Dr Tu’s discovery is an interesting one. In 1967, Communist leader Mao Zedong decided there was an urgent national need to find a cure for malaria when it was spread by mosquitoes and killing Chinese soldiers fighting Americans in the jungles of northern Vietnam.

A secret research unit was formed to find a cure. Tu Youyou was appointed head of Mission 523 and dispatched to southern China where malaria was rampant. For six months, she stayed there, leaving her four-year-old daughter at a local nursery.

When she started her search for an anti-malarial drug, over 240,000 compounds around the world had already been tested, without any success.

Finally, the team found a brief reference to one substance, sweet wormwood, which had been used to treat malaria in China around 400 AD. The team isolated one active compound in wormwood, artemisinin, which appeared to kill malaria parasites.

How the original Chinese texts helped is the story that should inspire our traditional practitioners: when the team tested extracts of the compound, nothing proved effective in killing malaria initially until Tu Youyou returned to the original ancient text. After another careful reading, she tweaked the drug recipe one final time, ensuring not to boil the extract, that then destroyed the anti-malarial property, but to extract it at lower heating temperatures or through use of solvents.

What should further inspire our practitioners of CAM (Complimentary and Alternative Medicine) is that Dr Tu did not have a medical degree, no doctorate, and had never worked overseas, the three pre-requisites we often consider essential for medical discovery. She was however observant, questioning and persevering in what she pursued.

Traditional medicine is a huge market today of US $ 60 billion. Chinese traditional medicine accounts for $14 billion. Indian traditional medicine also occupies a slice of the pie.

But it is that final proof that makes a compound or extract get global scientific acceptance. And that is where our Indian traditional practitioners should do well to work hard and leave their stamp.

How do you like your Tea?

By
The way we drink our tea may not only reflect our taste and style, but our health as well. Tea drinking is around 4700 years old and had its origin in China. Leaves of the shrub Camellia sinensis (tea plant) were in use at that time as a remedy for wounds and diseases. With the legendary emperor Shenong brewing and drinking its extracts, tea drinking became a popular habit in this part of the world. The British, impressed with the brew and the customs that go with drinking it in China and Japan, tried to emulate and evolve a tea-drinking custom of their own, and soon “tea-time”became a familiar term across the globe. Every home or cafe seems to have its own flavour. The north Indian variety of “chay” is a glass of hot creamy milk (more cream as it gets more “special”) with lots of sugar and a lacing of  “tea liquor” of strong tea that grows on lower heights (Assam, Nilgiri, Sri Lanka etc). In contrast, the Chinese and Japanese prefer light green or jasmine tea without a drop of mi...

Food Fads in Liver Disorders

By
In an attempt at trying to do well to those they love, spouses and parents often enforce diets on patients of liver diseases that often turn out to be detrimental. The commonest food fad is pale insipid boiled cabbage being doled out to nauseous patients suffering from hepatitis that makes them puke even more.  The liver, in a way, is a buzzing manufacturing unit that requires lots of energy to keep its multiple functions going. And it derives all this from the food we eat. During disease, such as during an attack of jaundice, when many of the liver cells get killed, the liver attemptsdamage control by trying to regenerate quickly. For its cells to multiply however, it requires a generous supply of energy that comes from carbohydrates, and protein, the building block for its cells and tissues. Boiled green vegetables unfortunately have neither of these. Hence the situation often progresses to that of a starved liver unable to recuperate due to cut-off food suppl...

Colas have No Class

By
Cola drinks, once a symbol of American upmarket style, is now to be found perched mainly on the shelves of road-side ‘paan walas’ and local grocers. True, there still are Americans who drink more colas than water, and consume an average of 2 bottles per day of the tangy fizzy dark drink, but it has clearly fallen in stature as offering it to visitors or serving it at parties is no longer elegant. Premiere schools in Lucknow such as La Martiniere College for girls have shunned colas from their canteen for the last 4 years. The story started with extensive campaigns by HOPE Initiative (Health Oriented Programs and Education) in 2005 creating awareness among the bright students about the long term harms of cola drinks. A heated debate followed in which the rights of an individual student  was pitched against the hazards of allowing gullible youngsters to be enticed by aggressive marketing to gulp colas and fall sick. The intelligent and alert La Marts students dcided on ...
