Related: Why Rasasindhura is not toxic

Researchers have employed a multidisciplinary project to prove non-toxicity of Rasasindura.
The study carried out in Bhabha Atomic Research Centre (BARC) and Raja Ramanna Centre for Advanced Technology came out with the conculsion that – “Our work not only helps to understand the non-toxicity of Rasasindura but also establishes the Ayurvedic synthesis method for a well controlled end-product,” researchers led by Dr Gebdutta Lahiri from BARC wrote in the latest issue Journal of Synchrotron Radiation.

In this study, researchers used samples of Rasasindura prepared as per Ayurvedic protocols.
The results obtained by the scientists apply only to the sample they used and not to any commercially available sample of Rasasindura.

Scientists used five analytical tools and procedures with Rasasindhura and nanoparticles of lab-based red á-HgS to prove that the structure of Rasasindura is indeed the very stable, á-HgS.

Surface organic groups or organic groups were absent in both.
Because of the special affinity of Hg to Sulphur, Hg-S bonds are very strong. Other workers have shown that accumulation of á-HgS in the human body is very low. Absorption of á-HgS by the gastro-intestinal tract is only 0.2 per cent; the fraction reaching the kidney is much lower at only 0.02 per cent. HgS is 10,000 times less toxic than methyl mercury.

The researchers showed that complete oxidation occurred in Rasasindura and free mercury or organic mercury was absent in it. They used synchrotron-based X-ray Absorption Fine Structure (XAFS) method to prove 100 per cent HgS formation in Rasasindura.

They found that that Rasasindura contains nanocrystals of about 20 nm size. Particle distribution is better controlled in Rasasindura than in á-HgS, made in laboratories. The paper proves that toxicity cannot be decided by elemental analysis alone.
