I was having a conversation that made me go "damn the Romans for using up all the herbal birth control." Normally I'm not interested in doing time travel because I am too queer, loud, non-binary, woman coded, etc. to not get some sort of societal consequence in most of history. Also I like modern medicine and such. But, it got me thinking about how it'd be cool to be able to bring a large silphium plant back from before it went extinct.

Obviously I have no idea of the efficacy of silphium for medicinal purposes but it would be super cool to be able to grow it, sequence the DNA, and try to reintroduce it, even if only in gardens. And maybe it's actually even effective medically.

So what would you bring back?

Caveats:

• You must be able to carry the thing
• The thing will not age when traveling forward in time but you'll be able to demonstrate that you brought it from the past.
• It should be one "thing." If that "thing" is made up of multiple smaller things (not atoms ಠ⁠_⁠ಠ)... Well, if you're trying to loophole then you're on thin ice, but if a reasonable case could be made, then make it and let your fellow Tildese judge you.
• You can't bring anything back in time besides yourself, your clothes and your time machine remote control button.
• You cannot bring a person to the present. An animal that you personally can carry, and that will let you carry it, is up to you.
