Ayahuasca. A bit different then herbal tea - you have to boil it for an entire day basically. Actually, I still need to reduce it today.... The entire process of making the tea is a ceremony - I even had to change my diet to make the best tea possible (it picks up subtle energy from you when you brew it). The cooking ceremony actually takes longer then the drinking ceremony (all day compared to 5-6 hours).
If it's not too personal and/or you don't mind me asking, what type of ceremonial tea? I make a lot of herbal teas, tinctures, etc. that I make in large quantities/batches at a time, but sometimes I'll make one w/certain herbs for specific purposes (like divining for example). Do you make a ceremony out of the entire process of making the tea or just use the tea for/during the ceremony itself?
Ended up also starting my 4th nettle dieta yesterday.... On a whim we decided we wanted to connect more with this plant as well (my favorite non-psychoactive plant teacher at the moment). Dieted with it 3 times last year, and we are just building on that work (each tie goes deeper). (For anyone who isnt familiar with the term "diet/dieta" in the way I am using it - it is a practice I learned in the Amazon which invites a plant spirit into your body to become a spiritual ally of yours.)
