I couldn't leave this thread without a constructive outcome. For OP and also for
@JosBoaz and
@Panpsychic, who seem to struggle with Tao of Rue tek, here is another one with more concise writing and some personal insights : forget Tao of rue and forget the hassle of manske/HCL. Freebase will cover all of your uses (oral, sublingual, smoked, even snorted), it's the most versatile form and the one who requires the less work. Here is
the tek I use for my extractions - thanks
@CosmicLion, Nexus is missing you - that I tweaked as follows :
- No need to grind/powder seeds : it's just more hassle to filter (it's not an instruction from this tek but from Tao of Rue). Time saving.
- Other than vinegar (acetic acid) can be used instead, I always use citric acid and have a pH of 4-5 in sight. If you can't measure pH precisely it's not a problem, pH strips do the job, the most important is that the water is acidified enough. Not too much because it could create an emulsion when you add the base. Weigh/measure your acid and water amounts, so you don't have longer to check the pH for next extractions.
- Start from sodium carbonate (SC) rather than converting baking soda to SC. Time saving.
- Prefer SC over lye, it requires less caution, it's less expensive and doesn't affect the yield (this tek doesn't mention lye but Tao of Rue does). Risks and cautions saving.
- You can discard first gunk from tea by passing the brew through a cotton cloth if you don't want to wait hours for the gunk settling at the bottom of the bottle (that's what I do). Time saving.
- Saturated Sodium Carbonate Solution (SSCS in the tek) can be done with measured amounts using a ratio of 2g SC/1cl water. Heat slightly the water for faster dissolving.
- Repeating the refining crude extracts steps 2 times is enough. You won't get much purer harmalas from repeating the step more times. Time saving.
- After the refining steps done twice, pour distilled water over the harmalas in the coffee filter until the water color is no longer yellowish. This is not mentioned in the tek but it's what allows to stick to only 2 refining steps.
- Dry -> enjoy.
Over time, you'll find yourself adding your own tricks, adjusting brew simmering time, using more adequate amounts of SSCS and so on.

Doing so really doesn't require high commitment. As I said, most of the time taken by the extraction is decanting time. You can expect 5% average yield of nice clear tan freebase (see pic), with variations in yield depending on seeds alkaloids content. Sometimes you might have weak seeds with only 3-4% content and sometimes (rarely) exceptionally high content seeds with 6-8%.

You can get your final product in 2-4 days if you accelerate the drying steps using a heat source. I’m never in a rush because I plan ahead for the extraction; I don’t wait until my last dose to get started.

Doses wise : freebase requires lower amounts than HCL. Tracers land start from 200-250mg doses. 400mg doses are more challenging. Expect insane tracers and stroboscopic visuals, auditory distortions, hypnagogic states and difficulties to move. My usual dose for more or less daily use is 150mg (oral) or 60/70mg (sublingual). Oral dose can be taken in capsule, freebase will be converted to salts by stomach hydrochloric acid. For faster absorption, freebase can also beforehand be dissolved in a few lemon juice (harmalas citrate), add a few water and gulp down the hatch. For sublingual use I put the powder in a capsule, drill small holes in it with a syringe needle, give it a bean shape and put it under the tongue. All should have been absorbed in about 15mn. Powder can be smoked/vaporized as it is but tend to clog if you roll it in a joint. Infused herbs to be smoked/vaporized can be done with IPA.

Those aiming for harmine/harmaline separation will need precise pH meter. It implies yield loss and more time consuming. I prefer to stick to mixed harmine/harmaline freebase. Harmaline brings its own psychedelic touch to rue experience.
Hope this helps.
