The extract decreased the crystal size by 5.22%–82.62% depending on the degree of supersaturation. Through analysis of the projected area of the crystals, the extract was found to shift the phase of the crystals from COM to calcium oxalate dihydrate (COD). This shift in phase is significant with a COM to COD shift of 88.26% at 0.5 mg/mL of extract and 91.53% at 1.0 mg/mL of extract. SEM images revealed aggregation of crystals at 0 mg extract/mL. At 1.0 mg extract/mL, the scanning electron micrographs showed discernible crystal unit boundaries.
