It may be a natural herbal paste made with leaves of a particular type of tree and that tree is not known. Like this, there are many people who give herbal paste for curing Jaundice. Those people also never openly tell what is the paste they are supplying.
Let us analyse the thing from a logical and rational angle. The natural, Ayurvedic, homeopathic, Unani, spiritual, astrological, worshipping a particular deity etc are the various ways which people believe and go for curing their ailments. These remedies are successful to some extent but may not cure all the people as the statistical success ratio of all these methods is limited to a lower percentage if the sampling is done honestly in a large population.
These things spread from person to person and people blindly join the fray. Some politicians to get cheap popularity support it in one way or other.
There have been innumerable cases in the past where such claims when tested scientifically were found either fake or effective only to the extent of statistical success which people already achieve with good life style, yoga , natural living, puja concentration etc.
We should not believe these things until unless they are confirmed and backed by scientific investigations. We must also remember that modern allopathy and medical sciences which are backed by enormous scientific research are also not 100% effective as in many cases the patients are not cured. But we believe in this therapy because so far it has the highest success ratio.
Knowledge is power.
Beware! I question everything and everybody.
