I do not apply kambo very often at all but the handful of times I did only one of them I did a pre-kambo enema for.
My memory is not 100% about exactly what I used but what I can remember is:
Place pink Himalayan sea salt in a 1-2L jar, maybe a teaspoon or two.
Then add desired essential oils the ones I used were lemon, peppermint, rosemary, myrrh. That is the ones I can remember but those are enough to accomplish your goal and likely beyond. I think it was like 2-5 drops of each and mix it into the salt pile and let it sit for an hour or two.
Then pour 1-2L's of boiling hot purified water into the jar add lid and shake vigorously for 5-15 minutes and let sit for 5 minutes after, before adding some or all of this to an enema bag first wait for it to cool to a temperature that is warmer than your insides but not hot enough to burn or flush you too early.
If you do this properly you can expect to feel like god for 3 days to a week or more, regardless if you use kambo or not.
When I first did this it dislodged massive physical blockages in my brain that I never knew I had until a few hours after doing this, I am talking about actual physical matter In the brain that does not belong not mental blockages.
Before my brain felt like a riverbed made of concrete and the fluids passing through it felt like sand, very unpleasant. After doing it my brain felt like a series of suspended fluids of different densities all moving in different directions all over the place freely amongst each other without resistance of any kind. Pretty sure it reset a considerable chunk of my brain, pretty much after doing it sensations and thoughts and imagination and essentially anything that made any part of the brain activate I would feel extremely clearly that exact location in my head activating and what direction it was flowing and what "flavour" the sensation was, and also each time this flow would be extremely strong oxytocin like electricity throughout the entire area of the brain this liquid-electricity was flowing through, so essentially every thought every consideration, every sensation every feeling for almost a week felt like a full body orgasms potency concentrated in whatever part of my brain was activated by the sensation or thought.
This last paragraph^ this event caused me to learn about brain chemistry in a direct hands on way through the language inside a language that was the plasma-like liquid electricity and the flavour of the orgasm like feeling it caused.
For maybe 2-3 weeks this persisted getting weaker every so many days until lit almost entirely stopped but there are positive changes that never went away, and that was well over a year ago.
Because of how potent all the sensations become it sort of wakes up both the observer and the experiencer at the same time and allows you to see beyond the fog of placebo and nocebo to know the reality of reality beyond duality. The way this clears the fog and things feel deeper and fuller and crystal clarity to thought and sensation will literally awaken the sleeping hyper genius in anyone who tries this enough times to get it working right, I never did an enema before but managed to get it working on my first try and I will mention that kambo did get applied after I did that enema but I highly doubt the kambo was key to this, if it was I used I think 3-5 dots on the tips of m fingers and I have done the same kambo treatment before 2 times and it never did anything like what the enema caused.
I am not saying kambo is not as amazing as what I experienced, I find the two experiences are similar but different, I find kambo to Be more body detoxing while I found this enema made me feel like all the negative physical matter inside my brain was expelled.
