Humanidad is a healing center focused on the therapeutic use of entheogens and master plants to treat physical, mental and spiritual conditions.

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

The treatments are guided by Guillermo Guillen, who has worked for more than 7 years with Entheogens and Master Plants.

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.

 


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”

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”

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”

It has been a crucial part… Read More “Definitely will come back!”

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”

Heart opening experience!!

Me and my partner did 3 Kambo sessions three days in a row with Guillermo in Lake Atitlan, Guatemala. It was the most beautiful and heart opening experience.
Guillermo created such a beautiful, safe and sacred space and served with such humility that which I have never experienced before.
We are so grateful for this man, the work he is doing and all he has to offer.

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”

Worth returning for an extended process

Guillermo’s intuitive spirit is sensitive, tender, and caring – paired with a subtle but persistent intensity and focus in his heartfelt endeavor to create the space for, and assist in, (re)discovering your own ability to shatter the paradigms you’ve inherited and created. There is a true commitment from this man that embodies the sacredness and respect that this path of plants and self-liberation calls for, yet it is balanced so… Read More “Worth returning for an extended process”

Supportive and beautifully natural setting

We loved our day long couples ceremony and how welcoming and warm Guillermo´s retreat centre was. It actually made our purging pleasant! The sauna and the homemade healthy food was also amazing. Our picnic outdoors by the peaceful Lake Atitlan, the herbal tea and beet juice blend was just perfect and so comforting after our ceremony. We could not of asked for a more supportive and beautifully natural setting for… Read More “Supportive and beautifully natural setting”

The treatments are completely personalized and tailored to the individual according to their unique circumstances.

Spaces at the centre are strictly limited allowing only to treat two participants at any given time in order to ensure that proper support and guidance is available throughout their entire treatment process. For the majority part of the treatment, participants enjoy the benefits of 1 on 1 therapy, offering total privacy and thorough service.

Treatments include post process follow-up through online consultations with Guillermo to help participants with the integration into their daily life. We offer pre and post treatment support with no additional cost.
