What is Ayahuasca?

### Etymology

The word *ayahuasca* comes from Quechua, an indigenous language of the Andes. It is composed of two terms:

- *Aya*, which means "soul", "spirit" or "dead".

- *Huasca*, which translates to "vine", "rope" or "rope".

Therefore, *ayahuasca* can be interpreted as "vine of the soul" or "rope of the dead", referring to its ability to connect the user with the spiritual world or transcend the physical plane.

### History

The use of ayahuasca has a long tradition among the indigenous peoples of the Amazon, with archaeological evidence suggesting that it has been used for at least a thousand years. It has been associated with shamans and healers who used it as part of their healing rituals and spiritual exploration.

The first written records about ayahuasca come from European chroniclers in the sixteenth century who documented the shamanic practices of the Amazonian peoples. For centuries, this drink has been fundamental in the indigenous worldview, being a bridge between the physical and spiritual worlds.

### Preparation

Ayahuasca is a decoction traditionally made from two main plants:

1. **Banisteriopsis caapi** (a vine containing monoamine oxidase inhibitors, or MAOIs).

2. **Psychotria viridis** (a plant that contains DMT, a powerful hallucinogen).

The preparation process is long and ceremonial. The lianas of Banisteriopsis caapi are beaten to separate the fibers and boiled together with the leaves of Psychotria viridis in water for several hours, sometimes days, until a concentrated concoction is obtained.

The shaman or healer guides the preparation, as the process is considered sacred, and the mixture must be done in a ritualistic context with respect for the plants and the spirit they contain.

### Traditional Use

In its traditional use, ayahuasca serves a ceremonial, spiritual, and medicinal purpose. Shamans use it to:

- **Healing**: Both physical and psychological. It is believed that ayahuasca can expel diseases from the body and soul.

- **Connection with the spiritual world**: Indigenous peoples believe that ayahuasca allows communication with spirits, ancestors or beings from other dimensions.

- **Self-knowledge and personal growth**: Many cultures believe that ayahuasca can reveal deep truths about life, the universe and the individual, helping to liberate emotional blockages or traumas.

### Non-traditional use

In the last few decades, ayahuasca has gained popularity outside its traditional contexts, especially in western countries. This phenomenó has given rise to "ayahuasca retreats" in places such as Peru, Brazil and other countries, where tourists seek mystical or healing experiences.

Non-traditional uses have also led to scientific research, particularly in the field of psychotherapy, where the potential of ayahuasca to treat conditions such as:

- Depression

- Posttraumatic stress disorder (PTSD).

- Anxiety

- Additions

However, these uses have also generated preoccupation in terms of cultural appropriation and lack of respect for traditional practices.

### Effects

The consumption of ayahuasca produces powerful effects both physical and psychological:

- **Visual and auditory hallucinations**: The DMT generates vivid visions of geometric shapes, landscapes, spiritual beings and memories of the past.

- **Altered perception of time**: Time may seem to slow down or stop.

- **Emotional catharsis**: People often experience strong emotions, which may include the release of trauma or suffering.

- **Nauseas and vomiting**: These symptoms are common and are considered part of the process of cleansing and spiritual cleansing.

- **Spiritual connection**: Many users describe feeling a profound connection with nature, the universe and their own inner selves.

### Pharmacology

Ayahuasca has two main components that interact to produce its effects:

1. **DMT (N,N-Dimethyltryptamine)**: It is a potent hallucinogen that is present in various plants. Normally, the body breaks it down quickly thanks to an enzyme called monoamine oxidase (MAO).

2. **MAO inhibitors (such as beta-carbolines in *Banisteriopsis caapi*)**: These substances inhibit the action of MAO, permitting DMT to cross the hematoencephalic barrier and cause its psychoactive effects.

The combination of these two components allows DMT to be active orally, which would not be possible without MAO inhibitors.

The effects can last between 4 and 6 hours, depending on the dose and the person who consumes it. During this time, there is an increase in brain activity in areas related to perception and emotion.

### Final Considerations

The use of ayahuasca outside of its traditional context poses both ethical and practical challenges. If it has been demonstrated that it has therapeutic potential, it is not without risks, especially for people with psychiatric or cardiovascular problems. It is essential that those who wish to try ayahuasca do so in controlled environments and with experienced guides to guarantee safety and respect for this ancestral medicine.
