My friend told me about Ayahuasca. He visited an Ayhuasca Retreat center Gaia Sagrada in Ecuador. I have searched internet to know about Ayahuasca. I found a website about ayahuasca, they mention there, what is Ayhuasca? 

But I am still not clear about ayahuasca retreats.  Should I I take Ayahuasca retreat or not?
