I believe this is a mistake. It's the leaves of the rhubarb which have the biggest levels and the plant in general doesn't have a toxic level. Spinach leaves actually offer a higher level of oxalic acid!
Parboiling in this way has been done to remove the tartness in rhubarb for many decades! It's quite effective!
Many blessings!
