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.

 


Brought a whole new meaning of life

To sum up my stay, Guillermo has brought a whole new meaning into my life and I have a completely new healthier and sustainable mindset.

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 life reset

I left Humanidad about three months ago, after a one-month psycho-spiritual development treatment, and I am still processing the changes that have happened since then. I came with a rather vague idea of what to expect, both in terms of process and teachings, and left with lessons that will stick with me for life and opened new paths of self-exploration. It was intense at times, but Guillermo supported me at… Read More “A life reset”

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”

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”

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.
