Humanidad is a healing center focused on the therapeutic use of entheogens and master plants to treat physical, mental and spiritual conditions. The blend of Ayurvedic, Amazonian and Western medicine makes the healing center one of a kind, rescuing the best of all worlds to provide a unique solution for each participant. 

We offer personalized (1 on 1) custom made treatments for treating conditions such as depression, post-traumatic stress disorder (PTSD), addiction to barbiturates and substances that create dependency with treatments that can range from 3 to 12 months.

We offer a holistic detoxification and spiritual development processes that can range from 1 to 3 months for those seeking physical cleansing, healing and deep connection with the self. 

We also offer spiritual retreats that can range from simple detoxification processes with or without the use of an entheogen of 1 to 3 days, to longer retreats of 5 to 12 days that entail a process of purification, isolation, silence, introspection and preparation for 1 or 2 sessions with a designated entheogen.

All sessions in our treatments and retreats are private.

The treatments are guided by Guillermo Guillen, who has worked for more than 10 years with Master Plants and specializes in treating chronic physical conditions with Chlorine Dioxide Solution (CDS).

Our purpose is to reconnect individuals to their own self-healing power and guide them to find the necessary strength so they can lead their lives from the wisdom that resides within their hearts.

 


UNCONDITIONAL LOVE

Two years ago I decided to give a quality shift to my life. I quit my job and started to travel alone through Central America in a journey to discover myself. I was amazed to everything that was happening during that time, but was missing something that I needed to find. It was at the end of my 6th month, before returning my first time to Switzerland when I met… Read More “UNCONDITIONAL LOVE”

A 3 month gift beyond Words

Words alone cannot fully capture the depth of my gratitude for my experience at Humanidad, and for the profound guidance of Guillermo and Joy. As I continue to reflect on my three-month journey this past winter, I find myself in awe of the wisdom and insight I gained, which would not have been possible without the loving connection to the plants, so beautifully facilitated by Guillermo and Joy. Every purge,… Read More “A 3 month gift beyond Words”

Changed my life for the better

I experienced an 8 day spiritual cleanse with Guillermo in 2014. Those 8 Days significantly changed my life for the better. I learned to be vulnerable, to trust myself, to step out of fear. What I received on that week’s Journey has stayed with me as I have continued to grow using the lessons that came to me through the isolation process. I will be back to see Guillermo and… Read More “Changed my life for the better”

Un abrazo del universo

Llegue a este camino cuando me encontraba en una crisis de pánico, sentí que no estaba viviendo la vida que me merecía y eran tantos mis miedos que me llevaron a buscar una solución profunda y real; puedo decir que llegue con tanto miedo y prejuicios hacia el proceso y con una mente fuera de control que racionalmente nosé como me atreví a intentarlo, ahora se que era Dios guiando… Read More “Un abrazo del universo”

A defining experience that continues to guide me

I had the opportunity to visit Humanidad twice: first for a month-long diet, and then for two weeks a couple of years later. I found that the support and care I received at Humanidad was firmly grounded in love, respect, and understanding. Both experiences were profoundly transformative. I realized that this process takes time for me; the shorter dieta ended just as I was beginning to delve deeper. In future,… Read More “A defining experience that continues to guide me”

Beautiful beyond words

For years I felt the pull towards Ayahuasca, but waited for the right guide. I met Guillermo in 2016 and instantly felt at ease in his company. His way is gentle but direct, unobtrusive but inquisitive, and I am always left answering much bigger questions that what I originally came with. In 2019, I went back to do a 10-day tobacco and ayahuasca diet. This time I really understood the… Read More “Beautiful beyond words”

Transformational experience

My 5 day retreat with Guillermo has been one of the most beautiful and moving experiences of my life. I met Guillermo and his team on a talk about entheogens and medicinal plants and I immediately felt an amazing trust towards Guillermo’s respect of the healing processes and immense knowledge of the plants. Since years ago, I have been curious about exploring my inner universe through Ayahuasca and I signed… Read More “Transformational experience”

From the depth of depression to a gratefully joyous life

It was the last straw that gave me the courage to seek help; not knowing what was to come. Now, 3 years later I come to the realization that it was the greatest gift to myself. I understand now that the main reason for my depression laid in the fact that I had become a full atheist and not a good one at that. I was an angry and a… Read More “From the depth of depression to a gratefully joyous life”
