This might not be for everyone, but after I lost my grandmother last autumn, I started working with mint in my grief practice, and something shifted. I’d read about the Hades and Persephone link, so I put fresh spearmint on my ancestor altar next to her photo. Didn’t expect much. Within three nights though, I had the most vivid dream of her kitchen I’ve ever had, right down to details I’d forgotten since childhood, like the pattern on her tea towels.
I’m still not sure if it was the mint’s underworld correspondence or just my subconscious latching onto the ritual, probably both, but it opened something I couldn’t reach with mugwort or wormwood. I’m still thinking about it.
