For some reason, I've waited on Maci_gumball for her herb and riddle for almost a month.... I broke my own rule by waiting that long, but- I own copyright issues.

Anyways, I've decided to make my own riddle:

When in anxiety, I help the most,
Burns, cramps too.
For little time, the cats use me,
I help the most with constipation.
What am I?

Worst riddle ever
