What is Ayahuasca? Uses, Mechanisms, and Safety Explained

Ayahuasca is a psychologically active tea or brew which is an attraction amongst many foreign people travelling to various destinations to explore and experience taking this tea. There are plenty of long-term advantages of having the tea, as discovered by prominent scientists. Nothing has only positive or negative side effects. Similarly, Ayahuasca has both positive and negative health effects. Here, we shall discuss all sorts of benefits, effects, origination, and history of this psychologically effective drink. 


Let us take a look at the Ayahuasca meaning.


What Do You Mean By Ayahuasca?

The tea originates in the Amazon and is also known as la purga and vine locally. The Banisteriopsis caapi vine’s stalks, along with adequate amounts of leaves from a shrub known as Psychotria Viridis, are used to make this special brew. Many other ingredients can be added as per the requirement of this drink. The Ayahuasca meaning in many religious communities and places of North America and Brazil is considered sacred and considers the drink as a spiritual beverage. Ancient Amazon tribes used it for various religious and spiritual motives. 


How is the Ayahuasca Drink Prepared?

Anciently, an Ayahuasca ceremony is led by a curandero or shaman who is a healer, and he boils the stems, stalks, and leaves of the required plants together in the water. It is done by smashing the contents so that the maximum medicinal values can be extracted. The plant material is left behind after the brew is reduced to the shaman’s liking and the water is removed. A highly concentrated liquid is produced by repeating the process, then cooled, after which all the impurities are strained. 


Can Ayahuasca Cause Hallucinations?

The leaves of Ayahuasca in India consist of DMT or N, N-dimethyltryptamine, which is an extremely strong hallucinating agent. It leads to an alternative consciousness like out-of-state experiences, hallucinations and more. We will learn more about the Ayahuasca experience later in this article. But it affects the main core brain along with the central neural network and system. 


What are the Benefits of Having Ayahuasca?

The Ayahuasca has got many benefits which are most often long-term and life-changing in reality. It affects the neurological portion of a person’s body and can positively affect brain health. DMT and other active ingredients of this tea have high neurorestorative and neuroprotective properties. It helps in protecting your brain cells by producing antioxidant compounds, and neurodegeneration is blocked. Harmine, another ingredient found in Ayahuasca in India, has memory-boosting qualities, anti-inflammatory, and neuroprotective properties. A study suggested that in four days, the growth rate of human neural progenitor cells can be increased by 70% using Ayahuasca. 


How can Ayahuasca Help in Overcoming Depression?

The overall psychological development of a person, mindfulness, and wellbeing can be increased upon taking this tea. Reports have shown that those who are said to have consumed the tea in proper amounts can even overcome depression and suicidal tendencies. The Ayahuasca experience also helps in treating post-traumatic experience, addiction problems, mood disorders, anxiety, and depressions. People have even given up on addictions after taking this tea which can impart hopefulness and increase the overall living standards of a person. 


What are the Negative Side-effects of Consuming Ayahuasca?

The consumption of Ayahuasca in India can even lead to death because of its alluring property. The most normal side-effects which are a part are diarrhoea, vomiting, panic attacks, and paranoia which can turn out to be extremely distressful. Furthermore, Ayahuasca sometimes can react dangerously with some other medicines such as weight loss medicines, Parkinson’s disease medications, antidepressants, and more.

Many diseases like schizophrenia can worsen if you intake this tea. Heart conditions such as blood pressure and heart rate can increase significantly with consumption of the Ayahuasca tea. Potential research is going on to determine whether this tea can be used to treat some serious medical conditions in the future to help the doctors.

FAQs on Ayahuasca in Biology: Effects, Benefits, and Risks

1. What is Ayahuasca and what are its main psychoactive components from a biological perspective?

Ayahuasca is a psychoactive brew originating from the Amazon basin. From a biological standpoint, its effects are produced by the specific combination of two plants. The primary psychoactive component is N,N-Dimethyltryptamine (DMT), found in the leaves of the Psychotria viridis shrub. The second key component comes from the vine of Banisteriopsis caapi, which contains β-carboline alkaloids, primarily harmine and harmaline, that act as Monoamine Oxidase Inhibitors (MAOIs).

2. Why are two different plants required to prepare Ayahuasca, and what is their combined biological role?

The use of two plants is crucial due to a synergistic biochemical interaction. The DMT from Psychotria viridis is orally inactive on its own because it is rapidly broken down in the digestive system by an enzyme called Monoamine Oxidase (MAO). The Banisteriopsis caapi vine provides harmala alkaloids, which are Monoamine Oxidase Inhibitors (MAOIs). These MAOIs temporarily inhibit the MAO enzyme, allowing the DMT to be absorbed into the bloodstream and cross the blood-brain barrier, where it can then exert its psychoactive effects on serotonin receptors in the brain.

3. What are the typical physiological and psychological effects experienced after consuming Ayahuasca?

The effects of Ayahuasca are profound and vary between individuals. Common effects include:

  • Physiological Effects: Increased heart rate and blood pressure, nausea, vomiting (often termed 'the purge'), and pupil dilation.
  • Psychological Effects: Intense visual and auditory hallucinations, altered perception of time and reality, deep introspection, retrieval of suppressed memories, and strong emotional experiences ranging from euphoria to fear.
These effects are primarily driven by DMT's action on serotonin 2A (5-HT2A) receptors in the cerebral cortex.

4. How does Ayahuasca's effect on the Default Mode Network (DMN) in the brain relate to its reported psychological benefits?

The Default Mode Network (DMN) is a large-scale brain network that is most active during wakeful rest and self-referential thought, such as rumination and thinking about the past or future. Research suggests Ayahuasca significantly decreases activity in the DMN. This reduction is hypothesised to temporarily dissolve rigid patterns of thinking and the sense of self, allowing for new perspectives and insights. This neurological 'reset' is believed to be a key mechanism behind its potential benefits for conditions like depression and PTSD, which are often characterized by an overactive or rigid DMN.

5. What are the potential therapeutic benefits of Ayahuasca being explored in scientific research?

Scientific research is investigating several potential therapeutic applications for Ayahuasca, although it is not an approved medical treatment. Preliminary studies suggest potential benefits for:

  • Mental Health Conditions: Showing promise in treating treatment-resistant depression, anxiety, and post-traumatic stress disorder (PTSD).
  • Substance Dependence: Some studies indicate it may help individuals overcome addiction to substances like alcohol and nicotine.
  • Neurogenesis: The harmine component has been shown in vitro to stimulate the growth of new brain cells, suggesting potential neuroprotective properties.

6. What are the primary biological risks of Ayahuasca, and why is it contraindicated with certain medications like SSRIs?

The primary biological risks are both psychological and physiological. Psychologically, it can induce intense anxiety, paranoia, or psychosis, especially in individuals with a predisposition to mental health disorders. Physiologically, the main danger stems from its MAOI properties. It is strictly contraindicated with Selective Serotonin Reuptake Inhibitors (SSRIs) and other antidepressants because the combination can lead to a life-threatening condition called serotonin syndrome, caused by an excessive amount of serotonin in the brain. It also poses risks for individuals with pre-existing cardiovascular conditions due to its effects on heart rate and blood pressure.

7. From a metabolic standpoint, how long do the effects of Ayahuasca typically last in the body?

The duration of Ayahuasca's effects is governed by its metabolism. The onset of effects usually begins 30 to 60 minutes after ingestion. The peak experience occurs around 1 to 2 hours into the session and the entire experience typically lasts for 4 to 6 hours. The MAOIs in the brew slow down the metabolism of DMT, extending its presence and effects. Once the MAO inhibition subsides, the remaining DMT is rapidly metabolised by the liver and excreted from the body.
