From purely a chemistry perspective, the amount of oxalate in an active dose is of minimal grounds for concern with respect to toxicity.
Quote:Some say that the levels of toxicity would be 400mg/kg, while others say that the levels of oxalic salts in typical 5-meo doses are so small (3-5mg) that it wouldn’t have any adverse effects.
Here the "400mg/kg" refers to the LD50 per kilogram of body weight of the test subject, so an 80kg human (if they were as sensitive - or insensitive - to oxalate as a rabbit) would have a 50% chance of death with 0.4x80 = 32 grams, or 32000mg, of oxalate. 5-MeO-DMT hydrogenoxalate contains just under 30% by weight of oxalate so you'd be exceeding the likely LD50 for 5-MeO-DMT well before approaching a level of harm from the oxalate present in the compound.
Calcium oxalate has a very low solubility so it's theoretically possible to convert the oxalate to the hydrochloride by mixing it with the requisite amount of calcium chloride.
“There is a way of manipulating matter and energy so as to produce what modern scientists call 'a field of force'. The field acts on the observer and puts him in a privileged position vis-à-vis the universe. From this position he has access to the realities which are ordinarily hidden from us by time and space, matter and energy. This is what we call the Great Work."
― Jacques Bergier, quoting Fulcanelli
