Background:
Rajata Sindura (RS) is a mercurial preparation, known for its properties like Rasayana (rejuvinating), Balya (strengthening), Vrushya (aphrodisiac), Medhya (increasing intellect) and can cure various diseases when used with appropriate adjuvant. It is prepared with Hingulottha Parada (purified mercury), Shuddha Gandhaka (purified sulfur) and Shuddha Rajata (purified silver) in a proportion of 1:1:4. Process standardization and characterization of RS are not reported until date.
Aim:
Pharmaceutical standardization and characterization of Rajata Sindura.
Materials And Methods:
Purified mercury and silver were triturated to form amalgam, followed by the addition of purified sulfur to prepare Kajjali and lavigated with Vatankura (leaf buds of Ficus benghalensis Linn.) swarasa (juice). This Kajjali was processed by Kupipakwa method.
Results And Conclusion:
RS was prepared in 33 h with 20.25% yield. Scanning electron microscope coupled with energy dispersive spectroscopy analysis has shown Mercury 86.21%, sulfur 13.27% as major elements; iron, calcium, potassium, magnesium and silver were other detected minor elements. X-ray diffraction report revealed the chemical nature of RS as HgS compound, having cubic crystal structure.
