Hi all this is my first post here... I've been reading the Nexus for a while it recently decided to jump in. My first question is how do you know what you're getting as far as root bark goes is actually what it supposed to be ? It's easy for someone to label something and give it to you as mhrb or whatever you're trying to buy but really it could be anything ? Due to current laws not like there's a lot of oversight seems like website pop-up here and there for a little while and then disappear. Let's just say for example you bought something online you thought was mhrb and you did a basic A/B extraction how would the average person know if the product that got was what they were looking for ? If some unscrupulous supplier gave you some random ground-up bark is it possible that what you're extracting could be harmful ? Is there anything that looks similar to spice that could be extracted from different kinds of bark that you wouldn't want or are the types of extractions listed here specifically targeting certain types of alkaloids meaning that if you have the wrong bark you wouldn't get anything for my pull ?
