Liquid Cardamine...

[Treewyrm]

Ok, I understand. I guess I just feel like an infocard for a rare or unusual item should include several rumors about the item, which are clearly listed as rumors, rather than only including one rumor and making it sound like fact. 'an easy way for Outcast smugglers to supply the drug to House inhabitants' indeed.

I don't have a certain answer to that I am afraid. See, the problem is that there are no guidelines about how such infocards are written, it is that they are in general tend to stay neutrally informative across the game, wikipedia-like. But so is wikipedia also very far from being comprehensive knowledge base, just providing basic concepts and general information. So I'd say consider item description infocards something like wikipedia topics, hence they don't contain rumors in them for most of the part as things there have to have a fact base (that is as far as "facts" go in fictional universe), not every wild assumption.

But I do have a few ideas to put in NPC rumors regarding Liquid Cardamine around, so instead of cluttering infocards it's NPCs who will provide a little more than what's generally available.
