The Ayahuasca diet/dieta and preparing for an Ayahuasca ceremony or retreat.
In terms of physical preparation, there is a lot of debate over what should constitute a pre-ceremony diet. When I use the term diet or dieta, I simply mean to exclude certain foods and stimulations which will allow you to connect with the plant(s). This is done for healing and to learn from the wisdom of the plant(s). You can find more info on dieting plants and trees here.
In terms of preparing for Ayahuasca this process has largely been brought in to combat the toxic diets of westerners. Any reference to MAOIs within the vine and a bad reaction with them has been referenced against pharmaceutical MAOIs. The two are not the same. In short, it is not necessary to diet before drinking Ayahuasca, although I do recommend it.
Sacrificing and streamlining your life before ceremony is a gift to the plants and a mark of reciprocity and respect. It also keeps you focussed on the journey you are about to embark on.
What I dislike is seeing half starved, exhausted people, turning up at the start of a retreat or ceremony. Please eat a hearty late lunch. If you have to break the diet as there is no other nourishment available at the time or during travel, I would rather you do that.
If you do decide to diet in preparation, I feel the following gives best results:
sexual activity of any kind, including self-love
Dark media, movies, and low vibration people
Salt (A small amount of Himalayan salt is OK if needed. By needed I mean if you become mentally erratic, disconnected, foggy, or otherwise challenged).
All spices (everything you eat should be quite bland)
All dairy (if possible, this is not a must do but it helps)
Foods fried in traditional oils (Canola, Vegetable, etc.)
Garlic, onions, leeks
All other mind-altering substances, including Marijuana
Gluten (can be eaten in moderation but works best if you avoid it completely)
No cologne, perfume
What to eat and do
All organic vegetables (except onions, garlic, leeks and spicy peppers)
Coconut oil, avocado oil, olive oil
Herbs (fresh or dried)
Salmon and trout
Organic chicken or duck
Rice, polenta, quinoa and other gluten-free grains
Corn tortillas (no flour)
Beans and pulses (unsalted)
Read books, listen to uplifting music, creatively express yourself
Journal, meditate, sing
Workout, yoga, dance
Smoke Mapacho or sacred tobacco
