Abstract:
Background: Uroliths are composed of organic matrix and organic & inorganic crystalloids.
Siddha drugs are used for the management of urolithiasis along with Musa sapientum inner stem
(inner core of pseudo stem) extract as the adjuvant.
Objective: To evaluate the in vitro antiurolithic effects of Siddha drugs Silasaththu paspam,
Nandukkal paspam and Venkara paspam with and without Musa sapientum inner stem extract as
the adjuvant on oxalate stones.
Methods: Fresh Musa sapientum inner stem extract strained through muslin cloth (333μl) was
diluted with 50mL deionized water. Oxalate stones (75.0mg) were treated with 3.3mg of each
different Siddha drugs (Silasaththu paspam, Nandukkal paspam and Venkara paspam) with and
without adjuvant (15mL) and incubated at 37°C. Deionized water (15mL) with the stone was used
as the control. After 24h, the solutions were decanted and the process was repeated 7 for days.
The decanted solution was analyzed for calcium, oxalate, magnesium, inorganic phosphate and
uric acid. The results were analyzed using IBM SPSS version 25.0.
Results: Cumulative release of calcium from oxalate stone into each of Silasaththu paspam,
Nandukkal paspam and Venkara paspam with the adjuvant were 4.678 (±1.12), 3.345 (±0.84) and
2.656 (±0.07) mg respectively, while cumulative release of oxalate from oxalate stone into above
were 3.047 (±0.84), 3.025 (±0.71) and 2.156 (±0.68) mg respectively. And cumulative release of
calcium from oxalate stone into Silasaththu paspam, Nandukkal paspam and Venkara paspam
without the adjuvant were [2.627(±0.98) mg], [1.994 (±0.91)] and [1.635 (±0.84) mg]
respectively while cumulative release of oxalate from oxalate stone into above were [1.848
(±0.48) mg], [1.804 (±0.87) mg], and [1.034 (±0.85) mg] respectively.
Conclusions: All selected Siddha drugs showed better in vitro litholytic activity with adjuvant
rather than alone. Silasaththu paspam with Musa sapientum fresh extract of inner stem showed
the highest in vitro litholytic effect on oxalate stones.
