Does lowering oxalic acid improve Crohn's symptoms?

Oxalate from Wikipedia

Oxalic Acid in Foods

"The latest news about spinach" from world's healthiest foods
"Spinach is one of only three vegetables that we recommend boiling to help reduce its concentration of oxalic acid. We recommend boiling for just 1 minute to minimize loss of nutrients and flavor. For more on the Healthiest Way of Cooking Spinach, see the 1-Minute Spinach."

"Enteric hyperoxaluria, recurrent urolithiasis, and systemic oxalosis in patients with Crohn’s disease" in Pediatric Nephrology (2012)
"Prevalence of recurrent calcium-oxalate (CaOx) urolithiasis (UL) is up to fivefold higher in Crohn’s disease than in the general population. Treatment options are scarce and the risk of recurrent UL or progressive renal CaOx deposition, (oxalosis) based early end-stage renal failure (ESRF), subsequent systemic oxalosis, and recurrence in the kidney graft is pronounced. We aimed to find proof that secondary hyperoxaluria is the main risk factor for the devastating course and correlates with intestinal oxalate absorption. ... As UL/oxalosis has major implications for the general health in patients with Crohn’s disease (ESRF and systemic oxalosis), new medication, e.g. to reduce intestinal oxalate absorption, is definitely needed."
