Physicochemical Characterization of the Siddha Metallo Mineral Drug - Veera Aya Chenduram (VAC)

Abstract

Veera ayachenduram (VAC) is a metallo-mineral drug cited in Siddha text literature KannusamiyamparambaraiVaithiyam. The study aimed to standardises the VAC by evaluating its physicochemical characters such as colour, ash value, pH value analyses the heavy metal composition in modern instrumental techniques. Inductively coupled plasma optical emission spectrometry (ICP-OES) and to find out the particle size through scanning electron microscopy (SEM) and. The total ash value was found to be 7.7% w/w, acid-insoluble ash value is 1.25% w/w, water-soluble ash value is 25.32% w/w, and The pH value is 6.5. The ICP-OES reveals that heavy metals such as mercury, lead, arsenic, and cadmium are within the limit. High-resolution SEM analysis of the drug indicated the existence of nanoparticles.
