Saxifraga

Since Saxifraga is indicated on calculi (biliar, renal), it seems interesting to remember the meaning of Saxi-fraga (from English Wikipedia):

The Latin word saxifraga means literally "stone-breaker", from Latin saxum ("rock" or "stone") + frangere ("to break"). It is usually thought to indicate a medicinal use for treatment of urinary calculi (known as kidney stones), rather than breaking rocks apart.

 "Saxifraga". National Plant Collections. Cambridge University Botanic Garden. Retrieved October 3, 2011 : The name Saxifraga is from the Latin meaning ‘stone-breaker’. This, however, refers to its ancient medicinal use for treating urinary stones, rather than the habit of many growing in and fragmenting rocks.
