Well it's not as simple as that, there's 'masculine' plants and 'feminine' plants :)
Do you have some sort of intention? Something that you wish to work with the Aya? Or would you be doing it out of curiosity? The latter not recommended.
But... if you're feeling the call... it does seem as though the universe is conspiring to bring it to your very doorstep! Ayahuasca isn't so easy to get a hold of, you can keep it in a fridge for quite a while. You might be surprised at who you could find where you are (America I presume?) to lead a ceremony, although I've never even been to America so what do I know? But if you put some feelers out with the Santo Daime community you might have some luck.
