Wow, this is a lot of information, RavensAscent! Thank you!
What book did you get this from?
I also found out that this plant, like most succulents, is hardy and can withstand desert climates. In addition, they readily propogate - injure the plant by pulling off a leaf or starving it of water, and new plants will sprout out of its stem and leaf cuttings, ready to continue its lineage. So, perhaps that does attest to its protection qualities, as it is strong enough to protect its own survival against such onslaughts.
It does have a strange weakness: If you water it and it gets strong, direct sunlight, the water stored in its fleshy leaves can “cook” inside. The plant takes on what appear to be scabs, as if to let you know it’s burning.
I’d always wondered how other people learn what to do with their herbs. I don’t always get the same information from a plant that others do. Take datura for example. Someone told me that it’s good for dream magic and psychic repair. But talking to datura and researching it myself, my impression was completely different, in that datura possesses strong baneful qualities. Since I have no reason to curse anyone right now, I haven’t worked with datura.
