Is South American bamboo edible?

I’ve been living in South America for a little while now and have been wanting to boil up some bamboo shoots. All my internet searches tell me is bamboo is toxic without being cooked, but won’t tell me if what species are toxic or edible in my area 😔 Does anyone know if Paraguay or it’s surrounding countries has edible bamboo? Or if all bamboo is edible after cooking long enough? cause google wont give me a straight answer
