My magical section includes herbs with a folklore history of magical properties - garlic to ward off vampires, mugwort for wild dreams, skullcap for the bite of a mad dog (plus just its name...), fennel to repel witches, clover for good luck, etc. Cannabis fits right in, as does Tagetes lucida (a mild hallucinogenic). I find it fun to research and mix them up. I had a very lovely dictamus which emits a volatile gas in the evening that you can light off, but it just up and died on me and is rather difficult to find (looking to replace it). I also had some absinthe which was a huge and sprawling plant, but I have terrible luck with any artimesia and it died before I could experiment with it.
I initially used Everclear as the vector for the insomnia tincture but found that way too harsh on my throat which is why I went to the rum - still pretty strong but not as biting. I keep it in a dropper bottle and only take about a half a dropper full if/when I wake up in the middle of the night. Since I don't take it on a daily basis, I think I will add valerian to the mix on my next batch and maybe a touch of honey to smooth it out a bit. This is one of the easiest concoctions to make - I just jam as many leaves as I can fit into a quart jar, cover with rum, let it steep for a month or so, then strain it.
My herb garden also has sections for culinary, medicinal, insect repellants, relaxation, female issues (aka the bitch corner), cosmetics, and the back is reserved for the tall boys - lovage, helenium, angelica, euphorbia, foxglove. This garden used to be our vegetable garden but was repurposed several years back to herbs.
