Are hollow spacees in rhubarb dangerous?

Hollow spaces in rhubarb stalks are not inherently dangerous and are often caused by environmental factors like rapid growth or nutrient deficiencies. However, it’s important to ensure that the rhubarb is fresh and properly prepared, as the leaves contain toxic compounds that can be harmful if ingested. As long as you are consuming only the stalks and they are in good condition, the hollow spaces themselves do not pose a health risk.
