why should the filter in water doctor or pureit be cleaned once in 6 months?

The water doctor or pureit water filter we use at home contains activated carbon as the adsorbent. Activated carbon has the  potential to remove odour colour micobes organic and other in organic impurities.  All these impurities get adsorbed (not absorbed) on the surface of the carbon. Every time water passes through the carbon the impurities get adsorbed and Clean water gets filtered. This process goes on till the surface can hold the impurities.  After the whole surface is filled with a layer of impurities the activated carbon can no more hold impurities and it slowly starts desorbing. When we don't change filter desorption takes and when we drink this water infact we are consuming all microbes accumulated along with desorbed impurities.
Therefore we should change the filters or best way is to boil water for at least 15min and drink.

How can we remove bad odour or smell inside a fridge?

Keep some charcoal powder in a bowl. Or activated  carbon.  This removes the smell. Activated carbon is a very good adsorbent.  It can adsorb colour smell and microbes. 

How to prevent growth of parthenium?

Spraying a mixture of salt and soap solution prevnts growth of parthenium.
Most effective way is to spray copper sulphate

How to get rid of unwanted hair or facial hair?

One best way is using pumice stone everyday along with soap. This reduces hair growth.  Use of pumice for 2 to 3 months gives gold results.

What is so special about turmeric?

A recent survey revealed less cancer statistics in South India compared to other countries.  We use lot of turmeric wh contains curcumin, an anti cancer agent. Our ancestors have used turmeric with salt.  Curcumin with salt forms sodium salt of curcumate wh facilitates absorption of curcumin .Hence in our food preparations its good to add turmeric and salt together. Prep like mor kuzhambu are thus good and should be taken once a week.

how to clean your white vegetable cutting board?

Normally those who use a white vegetable cutting board feel that how much ever you clean the board it still is dirty with all stains. Add few drops of Rin Ala onto the wet board leave it for 15min and wash off with soap to get a white clean board
It really works! !

how to combat vitamin deficiency in a natural way avoiding tablets?

For long I have wondered why we take so many vitamin tablets when our body can absorb only very less of it.
Vitamin B1 or thiamine deficiency can be overcome by taking rice waterwash with a pinch of salt.
Vitamin C by taking Lime juice with salt
Vitamin D by simply standing for some time in morning sun
Vitamin A by taking carrot  in empty stomach or carrot juice with a spoon of milk

In general we can get intake of all vitamins by including greens veg and fruits

why is abishekam (pooja) milk good?,

Milk is a natural bleach. It can remove dirt and dissolve elements to a small amount. Ancient temples have idols made of panchaloga (madeof 5metals) .our body requires minerals in small quantities . our ancestors have standardised this amount as few millilitres- the amount given to us after abhishekam In take of this milk once a week replenishes our essential mineral intake. 
IN my opinion lets not avoid this milk when given in temples and lets visit temples a week!

Alarming Vitamin B12 deficiency- Tingling feel? you may be Vitamin B12 deficient!

Vitamin B12 deficiency is a silent deficiency disorder on a increase in vegetarians!
Tingling feeling, tiredness, nervous weakness are some of the notable symptoms seen in this deficiency. When somebody pulls a chair strongly a normal person get annoyed but does not  physically much bother us. But this is not so in the case of vitamin B12 deficient people. It produces a strong tingling effect. Mostly palm and feet sense this feeel more and even intake of tablets for a period of time does not cure this. Injections of B12 - methylcobalamin seem to be more effective.

So how do we combat this deficiency or take some precautionary measure to avoid this!
Vitamin B12 is present in appreciable amounts in liver of animal foods. Vegetarian foods lack vitamin B12. Soya has meagre amounts of this vitamin. Hence this deficiency is called a vegetarian disease. 
If you are a non-vegetarian, give your child liver before the age of 15 when the absorption of vitamin b12 is appreciable. This will not produce this deficiency in your life time.!

Best source of Vit B12: rain water, soy milk, Liver (meat)

does iron interfere with calcium absorption in food?

THERE ARE SEVERAL RESEARCHES AND ARGUEMENTS related to absorption of minerals from food.  Its true that iron competes with calcium absorption but does not interfere. Also food preparations are a mixture of varied nutrients. Hence when speakung of a normal diet calcium absorption is not interfered by iron. Except when we take gelusil or such exexternal calcium sources iron absorption may be interfered. Otherwise milk helps in absorption of vitamins particularly vit a d e and k since these are lipid soluble.  Hence in short iron will only compete with calcium and not interfere.

Always synergistic effect only plays a role as far as food prep are concerned.

Ward off evil eyes with salt , pepper and dry red chillies? is it a myth?

Its is customary to use common salt, pepper and red chilly to ward off evil eyes. This is normally done for children mostly for kids. In south India it is common . After few days from birth, this is followed. The science behind it speaks of the chemistry our ancestors knew. Amazing!

Common salt , pepper and chilli take up the bacteria and virus surrounding a person( lets say when your mother uses these in her closed fist and does the suthi podufying ( excuse my language- so that  bloggers understand) with the intention of warding off all evil eyes, all virus, bacteria and other germs are taken up in this medium and this prevents infection. This is also the principle involved in Reiki treatment where the surrounding air is cleansed to cure a disease. To expose our body surroundings to more salt, it was made mandatory to use salt , pepper etc taken around 3 times or nine times both clockwise and anticlockwise direction and to discard without turning back !. The salt does not provide the optimal environment for the microbes to grow. In case of child birth, the new born is visited by many people relatives, neighbours and many well wishers . Increase in number of visitors over a closed area ( since the new born is confined to a closed space) increases microbial concentration in the room . Hence this system was adopted wherein salt removes microbes in the air in the closed space. 

so in the case , when a kid achieves something, a mother is excited and does this suthi poduthal- whenever there is an achievement, people have the habit of congratulating, shaking hands etc which causes more transfer of microbes. HEnce be young or old, using salt to ward off this microbes slowly became warding off evil eyes. 

IF your kid or yourself suffer from an infection be it a fever, common cold or any other pain, using a handful of salt and taking it all over your body from top to bottom and all over the body- clockwise and anticlockwise for atleast 2 minutes will ease you from pain. THis salt should immediately be washed off. 

WARD OFF MIGRAINE BY SIMPLER MEANS!

Migraine is a common problem noted when there is sodium deficiency. At the onset of headache, a glass of water with salt and lime should  be taken. The lime peel can be applied on the forehead. This will ward off the migraine. 

Multani Mitti (Fuller's earth) is nothing but a form of mud

 or clay. When this is mixed with honey or curd or lime 

juice or milk it not only gives glow to your face but also 

relieves you from headache.

What is fever? Why should you take a course of antibiotics?

What is fever?
Fever is a symptom indicating the presence of  a foreign substance in the body be it a objects or bacteria, virus etc. There is an increase in temperature which should be brought down by wet cloth swab. This is to ensure that we dont lose moisture from our body and get dehydrated. The functioning of  most of the organs is also disturbed when the temperature of the body increases. HEnce care should be taken to bring down the body temperature. 
Do not immediately give crocin or any anti-pyretic tablet . Analyse the causative for the onset of fever. 
When doctor prescribes a dose of tablets say 8 tablets , do not skip these. 
Bacteria forms spores when you take the first tablet. It becomes inactivated. Immediately we feel that we are cured. No fever! No tab!
But the bacteria is only inactive. With the second tab it still more hardens the cell wall as a self defense. Further doses act on the cell wall and kills the bacteria. If you stop with two tablets , the bacteria inside the spore starts multiplying and after few days there would be an outburst of bacteria which would act with full vigour . In this situations the common broad spectrum anti biotics might be resistant.
that is why you should take a full dose of prescribed antibiotics or medicine
