Err century plants (if you mean agaves), don't have limbs?

I wonder what you pruned ?

Called them limbs, cause they r too big to be called leaves?

Wiki:
"The juice from many species of agave can cause acute contact dermatitis.[16] It will produce reddening and blistering lasting one to two weeks. Episodes of itching may recur up to a year thereafter, though the rash is no longer visible. Irritation is, in part, caused by calcium oxalate raphides. Dried parts of the plants can be handled with bare hands with little or no effect."

Mentioned in this chart.

Sorry you are one of the unfortunate folks sensitive to such things. I am too! TY for sharing what happened to you.
