I have heard that rhubarb shouldn't be eaten after July because of

eat rhubarb after this date? How dangerous is it?

Erm your kidneys get stones I think. Not pleasant if you have one of
those.

I think there was some in the shops the other day though so perhaps
not.

The theory is that the oxalic acid combines with calcium to make
insoluble calcium oxylate crystals that can cause problems in joints.

But it makes sense not to keep pulling rhubarb in order to allow the
plant to build up strength again for the next season.
