Hi Red Cat! Welcome!
I've been meaning to reply to this fascinating thread of yours for a while. Your intro post was quite the story to read, very forthcoming, and it's great to see a septeguenarian boldly exploring altered states of consciousness. Thanks for sharing it all and I wish you the best regarding your health.
I have two things to share:
Regarding your cancer struggle: A university nearby has just started doing studies on dandelion root extracts for treating cancer. The reason they started the study is the doctors happened to notice that terminal patients with a variety of cancers who started drinking dandelion tea extracts consistently experienced remissions of the cancers. Here is a link about the clinical trial they're doing in case you're interested in this information. It certainly wouldn't hurt to drink some strong dandelion tea a few times a day as your own personal experiment over the next year: First cancer clinical trial approved.
Maybe share that with your oncologist and they can get in touch with the Canadian doctor and discuss best-guess dosage and find out how the clinical trial is going so far, before the published results eventually come out?
Regarding the prior poster's suggestion of Salvia divinorum, I second that recommendation for sure. It's an amazing plant. Thankfully, Salvia the plant, and its active ingredient Salvinorin A, is NOT a scheduled substance here in Canada yet, so we can come and go with it, grow it, or sell the live plants freely without risking a criminal record. The products/tinctures/extracts of it technically fall under Health Canada herbal supplement regulations since it's not scheduled. So far, Health Canada does not fine or enforce removal of all the not-yet-approved extracts from head shops, convenience stores, and online vendors. It's simply not a priority for them I suppose.
Everyone I've experienced Salvia divinorum with was very glad to have discovered it, and found it profoundly consciousness altering. I look forward to someday contrasting & comparing that experience with the primary subject of this website.
From personal experience, I can say with certainty that Salvia divinorum is easily grown as a houseplant in indirect light by a window, without a humidity tent, once acclimated to that environment gradually. Don't bother with the expense and hassle of setting up a complicated growing environment. Clone it into 6 plants by taking and rooting cuttings in glasses of water from the growing tips. 6 is a good amount of plants to have around for personal use. I recommend the "Luna" strain as the hardiest for low-maintenance home growing, by far. PM me if you continue to have a vexing issue getting your hands on a live plant through your extended social circle and I'll see what other ideas I can come up with that, who knows, you might not have already thought of or tried.
I love growing a wide variety of medicinal and edible landscaping plants for fun, and it's nice to see someone else interested in cultivating and revering Magic Mint.
Again, welcome!
