You have to differentiate between the ancient use of traditional herbs and the modern use of concentrates and extracts. DMT is already in salt-form in MHRB. Thus it will dissolve in water. But only what is available. Any DMT-salts 'locked up' inside the vegetable matrix will hardly end up in your tea. DMT-salts are only moderatly soluble in alcohol. On the other hand, the alcohol *might* soften the cellulose somewhat. But you really need a pretty strong base to do that to any appreciable degree. I would stick to one of the tried and tested ways. Somebody probably has done what you want to do at some time in the past, but the fact that we don't read about it often (or indeed at all) probably means it has failed to produce a worthwhile product.
Depending on your stance, you can choose either way:
- The traditional way. Handed down over generations. Respecting Mother Nature. Living in symbiosis with the plant. Being probably slightly more safe from a legislative point of view, after all you're doing shamanic stuff. BUT: not very efficient and rather time consuming. Plus you'll have to cook the stuff for hours producing billowing vapour in your back yard. Also it will not keep very good and can become mouldy after a few weeks, even in the fridge.
- The western way, making a fast concentrate that's easy to dose and store and highly efficient. But it uses toxic chemicals. It is (in cases other than DMT) easy to overdose. And on top of that you're definitely making drugs. The law is very clear about making drugs.
So it's your choice: are you a shaman or 'just' a westerner?
