Electrochemical and spectroscopic study of therapeutic effect of Prunus avium L. tail herbal tea on formation and dissolution of calcium oxalate kidney stones

Kidney stone is one of diseases that more than ten percent of the population suffers from it. Calcium oxalate is the most well-known type of the kidney stones which no chemical medicinal treatment presented for it. The use of herbal products can be a good way to prevent the formation or dissolution of these stones. This study was carried out with the aim of determining Prunus avium L. tail herbal tea effect on the formation or dissolution of calcium oxalate.
In this study, the herbal tea of 4.0 g dried Prunus avium L. tail in 100.0 ml double distilled water was prepared and its effect on the formation and dissolution of calcium oxalate was investigated. The solubility of this salt in mixture containing 33.3% (v/v) of herbal tea was studied by complexometery and spectroscopy methods. The concentration of Ca2 in saturated calcium oxalate solution was determined by titration with 0.01 M Ethylenediaminetetraacetic acid and light emission in complexometric and spectroscopic methods, respectively. In order to investigate the formation rate of calcium oxalate salt, the titration of 0.05 M calcium chloride solution containing 33.3% (v/v) of herbal tea with 0.05 M sodium oxalate was performed.
The results of flame photometery, complexometery and conductometery techniques reveal that, although this herbal tea cannot have good effect on the dissolution of calcium oxalate stone, it significantly prevented the stone formation (P The results of this study show that Prunus avium L. tail herbal tea can be a good choice to prevent diseases in people disposed to kidney stones.
