Urinary stone disease has become one of the common causes of morbidity and affects upto 5% of the population. Brushite or Calcium Hydrogen Phosphate Dihydrate (CHPD) also known as urinary crystal is a stable form of calcium phosphate. In the present study, the brushite crystals are grown by single diffusion technique in silica gel at room temperature. The effect of herbal extract of Ocimum Tenuiflorum is used as additive to inhibit the nucleation and growth of the brushite crystals. The crystals harvested are characterized by powder X-Ray Diffraction, UV-Visible spectral analysis and Dielectric studies. From the PXRD it is found that the crystallite size is reduced for Ocimum Tenuiflorum added CHPD crystal while comparing with pure CHPD. UV-Vis spectra shows that the optical band gap energy decreases for Ocimum Tenuiflorum added brushite crystals. The frequency and temperature dependence of the dielectric parameters were different for pure and Ocimum Tenuiflorum added crystals and throws light on the polarization mechanisms in these crystals.
