What if any are the differences in strain colors?
Do certain colors contain more harmalas?

judging from the different intensities and effects reported they should entail two main variations, one is the amount of alkaloids, some are stronger and some are weaker, the other is the ratio of alkaloids, some have harmine alone, some have it with THH and harmaline etc

some colors of caapi are known to cause more tremors and shaking than others, these are typically those used by shamans but are not those given by shamans to patients.

There are actually hundreds of reported strains from many tribes. Many of which have very specific effects. Some that just teach people how to fish or hunt a certain animal. Meztiso Curanderismo practice primarily works with just 5-6 varieties for specific purposes. Most people have only know about the for of five and tend to think that those are different due to harmala or alkaloid content. Which would be the obvious notion. There's something more to it then that however. Suggestion? Or perhaps something deeper... Lord knows if they start selling a caapi strain that has been used for hundreds of years to teach how to catch fish what will happen to western aya drinkers and changa smokers!
Vegetalismo by Eduardo Luna has a fairly good list of the different vines.
Swim actually helped introduce the different colors of caapi to the ethnobotanical market years ago. It was a serious intrest of swims...

Awesome, thanks guys!
Thats insane that they have strains specific for hunting knowledge!! I had no idea.
Well im hoping to start my aya garden soon so I got some white ceilo caapi to start, seemed like the most popular and I dont think I'm ready for anything close to a shamans experience....yet
