This may be common knowledge. I am simply compiling what I have just recently learned so that others may make their own conclusions.:I think the biggest issues I keep reading with failed experiences is that they lack any similarities with actual ayahuasca dosing. This indigenous dosing, as far as I am aware, involves drinking multiple "doses" to achieve anything impressive.
According to Ott: [Ayhuasca Analogues by Jonathan Ott, 1994],
"All samples (16 total) but two contained harmine as the main alkaloid
All samples but two contained harmine as the main alkaloid, representing between 40 and 98% of the alkaloidal fraction. In the two exceptions, 42% harmine was exceeded by 47% THH in stem material obtained from Piro Indians of Peru, and 40% harmine was surpassed by 44% THH in roots of Rio Purus B. caapi, the stem, branches and leaves of which contained 77-94% of their total alkaloids as harmine. With these two exceptions, all samples contained THH as the second most important alkaloid, representing from 1-47% of the alkaloidal fraction, wheras harmaline was the third most concentrated leaf alkaloid, from traces up to 17% of the alkaloidal fraction."
"The overall average for all of the 16 samples analyzed is 158 mg carbolines and 29 mg DMT per
dose."
According to Jordi Riba et al. [Human Pharmacology of Ayahuasca: Subjective and
Cardiovascular Effects, Monoamine Metabolite Excretion, and
Pharmacokinetics 2003]
"a 9.6-liter batch of Brazilian
Daime was subjected to a freeze-drying process that yielded 611 g of
powder"
"One gram of
freeze-dried material contained 8.33 mg of DMT, 14.13 mg of
harmine, 0.96 mg of harmaline, and 11.36 mg of THH"
"The low and the high dose contained, per kilogram of body
weight: 0.6/0.85 mg of DMT, 1.0/1.4 mg of harmine, 0.07/0.09 mg of
harmaline, and 0.82/1.16 mg of THH."
This corresponds to (assuming 150lb individual)
40.9-57.95mg of DMT, 68.18-95.45mg of Harmine, 4.77-6.13mg of Harmaline, and 55.90-79mg THH.
From this we can thoroughly conclude that Harmaline has a negligible impact on the effect of most Ayahuasca brews. Furthermore, THH has been proven to be a very weak RIMA so it's efficiency in a pharmahuasca preparation should be considered negligible.
Also from Ott:
"the typical reaction to harmaline is a closed-eye contemplation of vivid imagery... which is in contrast to the ecstatic heavens or dreadful hells of other hallucinogens. But the few first-hand reports of the effects of ayahuasca potions stress powerfully emotive "hallucinogenic" or entheogenic effects - the ecstatic heavens and dreadful hells are more decidedly a part of the psychic territory of ayahuasca. As one Cashinahua Indian informant had commented:
"it is a fearsome thing, I was very much afraid""
Not from Ott, but equally important:
"Fear cannot be without hope nor hope without fear."Personal ruminations:An example of indigenous dosing mimicked effectively could be as follows:
Time - Total dose
T=0 - 50mg Harmine
T=30 - 100mg Harmine
T=60 - 150mg Harmine, 50mg DMT
T=80 - 200mg Harmine, 50mg DMT (Final dose in gulp)
This dosage outline is a rough guideline, and doses should be consumed in liquid form spread out based upon the timeline. So within 30 minutes, 100mg of harmine should be ingested. From 30 minutes onward, the liquid should be imbued with 100mg DMT (or whatever your respective dose would be based upon weight), half of which should be consumed within the next 30 minutes. The last half should be consumed in one gulp 20 minutes after the final "slow" dose.
To attenuate nausea, Deglycyrrhizinated licorice preparations can be consumed as directed, and especially prior to the administration of RIMA's. DGL increases mucus secretions within the intestines and therefor would lessen nausea. DGL also increases intestinal motility and would help move things along with repeated dosing.
I'll try this out with 3 friends and report back on my results. I think spacing out the RIMA will reduce nausea, and spacing out the DMT will allow for a more relaxed come-up. In the Riba paper, the time until peak concentrations of DMT was 1.5 hours. Dose one would give a steady introduction to effects until dose two gets fully digested and begins to take hold.
