Drinking caapi or rue tea is a good option. Eating rue powder must be quite disgusting. You could also extract harmala freebase from either caapi or rue. You can eat that, or you can make changa with it.
Before you experiment with harmalas, be sure to check the
substance interactions. When in doubt about a substance not mentioned there, often there's people in chat who know.
The advantage of extracted alks is that dosage is not a guessing game. From very quick reading, my impression is that 20g caapi leaf shouldn't be too much - please someone experienced with caapi correct me if that's wrong.
Changa has some advantages:
- you don't have a lot of inhibition in the digestive system, so food restrictions are more relaxed
- you don't have to wait between harmalas and DMT because you smoke them together
- you need much less harmalas (10-20mg rue alks in a hit of changa, ~200mg oral)
- the harmalas don't last much longer than the DMT
If you take oral harmalas, inhibition will last for several hours. If you also take oral DMT, this means your journey will last several hours. If you smoke the DMT instead, journey will last around 30-60 minutes. You'll still be harmala drunk for hours, can smoke more DMT if you feel like it.
I haven't done full aya/pharma yet, so i can't tell you about dosage or qualitative differences. All i know is that harmala dosage has strong influence on required DMT dosage.
One approach is to test the waters with harmalas alone (or accompanied by smoked DMT) to find your dosage for full inhibition, before ever adding DMT orally. That's the process i'm in - I've had 170, 210 and 250mg of rue alks so far, will go a little higher but i'm almost there. It tends to take longer than 30mins for me to feel full oral harmala effects. Once I'm ready for pharmahuasca, I'll start low with the DMT, like 15-25mg.
Whether tea or freebase, I'd keep a bowl handy just in case
