I am getting ready to start my own adventures in extractions and was wondering about Acacia bark.

Would it be better to get inner bark or root bark of the same tree?

I am hoping to aquire some acacia some day and those are my two choices.
The inner is from Taiwan while the root (as listed) is from Hawaii....


Still learning here.. sorry if I broke any rules

Also what is the rule of thumb about posting links to a site where one might aquire ACRB?

I've stumbled across something and I'm not sure if it is legit
