It might be nice but the only thing I'd be worried about is that taste lingering and affecting the herb taste.
kava kava root, lemon balm, sour d (great for colds), peppermint. I like to try out new things in there. No lingering taste when I clean it out, but each herb has some sort of benefit to your body. Just be careful with things like lavender, that can make you sick
oh, cause i was thinking about the wicked og bubble hash, im flattening out and put over grand daddy purple and vaping up with my heat island log vape. vapor bong loads. big vapor bong loads
