on the above quoted question, double blind study is not necessary.
Double blind study on what claim?
Qureshi - you do know what adouble-blind placebo controlled trial means don't you?
You need to get a group of people together willing to undergo the test. The more the better but twenty would be OK to see if there really is an effect.
You should tell everyone exactly what you propose to do.
You then need to give half of the people Camphor 30C and half the stock solvent or pill - this is the placebo.
It is very important that neither the subjects or whoever gives them the remedy knows whether it is Camphor 30C or the placebo - this is the double-blinding.
You will probably need a third party to help with this bit - someone to make up 20 doses (10 of each) and mark them so that they and no one else knows which is which. This person (or persons) should not be in contact with the subjects prior to or during the test.
All the subjects will have their temperature taken before receiving the remedy (or placebo) and 15 minutes afterwards and the results recorded.
Only when this has been done should you check to see who got what.
If there is a consistent difference between the group that got the Camphor 30C and the placebo group then you are really onto something.
In fact you could be in line for
