The objective of this work was to evaluate the in vitro diagnosis of calcium oxalate kidney stones using a solution made from a mixture of Bryophyllum pinnatum powder, apple cider vinegar, and lemon juice. Two surgically removed stones were dipped in this solution and the results showed that the kidney stone completely dissolved in the lemon juice solution, while a considerable weight reduction was observed in the apple cider vinegar solution. Fourier transform infrared spectroscopy and Raman spectroscopy confirmed the dissolution process. Scanning electron microscopy images revealed cluster formation and aggregation of particles. This in vitro study proves that a mixture of Bryophyllum pinnatum powder and lemon juice is an effective remedy for removing kidney stones.
Urolithiasis is one of most common renal disorders, characterized by the formation of kidney stones (renal calculi) through the crystallization process within the urinary system. The frequently observed renal calculi are calcium oxalate renal calculi and treatment is done by shock wave method or lithotripsy which is harmful for other cells of the internal system. The objective of this work was to evaluate in vitro diagnosis of calcium oxalate kidney stones in the aqueous solution of Bryophyllum pinnatum. The B. pinnatum powder was mixed in apple cider vinegar and lemon juice separately to make solution 1 and 2 respectively. Apple cider vinegar and lemon juice were used as solvents due to their acidic and body compatible nature. Two surgically removed stones was dipped in solution 1 and 2. After two weeks, kidney stone of weight 2.7 g is completely dissolved in solution 2 while a considerable weight reduction of other kidney stone has been observed in solution 1. Fourier transform infrared (FTIR) spectroscopy results show the presence of two strong absorption peaks at 610 and 912 (cm-1) in both solutions after dissolution of urinary stones are related to calcium oxalate dehydrate (COD). Raman spectra further confirm the dissolution of COD in solution having Raman shifts at 504 and 910 (cm-1). Cluster formation and aggregation of particles has been observed in scanning electron microscopy images. This in vitro study proves that a mixture of Bryophyllum pinnatum powder and lemon juice is a best remedy to remove kidney stones.
