Dos Santos et al. reviewed several clinical trials on ayahuasca, psilocybin, LSD, and their effects and concluded that all these drugs could be beneficial in treatment of depression (especially in treatment-resistant subjects), as well as anxiety and alcohol and tobacco dependence. Confirming these findings, Stuckey also reported similar findings in the Hz bands, frequencies implicated in cross-modal sensory processing, and hypothesized a link between this and the intense synesthesia experienced during ayahuasca experiences. In a study by Cavnar , self-identified gay and lesbian ayahuasca users reported feeling affirmation of their sexual orientation. All participants reported ayahuasca rituals were pivotal to attaining abstinence or achieving less harmful patterns of drug use; they also reported ayahuasca was instrumental in understanding the causes of their addictions. In a questionnaire, 25 Northern European ayahuasca users reported increased self-awareness, being more loving, more empathetic, having greater creativity and new interests especially with nature, and having a more meaningful inner world .

Answers that were shared with a single participant were valued as 1, and answers that were shared by three or more participants were rated zero. Alternative answers that were uniquely reported by a single participant received an originality score of 2. Originality is calculated by evaluating the originality of the alternative association relative to those provided by all other participants in a session.

This finding appears counterintuitive considering existing evidence on the positive effects of psychedelic therapy for depressive symptoms . Moreover, the complexity of defensive networks is central in emotional processing and response (e.g., ). This may reflect symptomatic improvements within the sample, though the relatively low prevalence of these disorders (19.7% depressive, 14.2% anxiety, 9.2% substance use, and 10.0% alcohol use disorders) could also explain their diminished importance. This suggests, from a sociological perspective, that individuals who start and continue using ayahuasca are mature, with their personalities already formed, and that ayahuasca use is not merely about seeking to get high.

Though Ayahuasca is often praised for its therapeutic benefits, it can also have lingering effects. While this can be transformative, it may also lead to confusion, fear, or difficulty integrating the experience afterward. Some people experience paranoia, fear, or a sense of impending doom, especially if they resist the experience. It’s essential to consult a doctor before participating in a ceremony if you have any heart-related concerns.

Machine learning and statistical methods were used to examine the relationship between sample characteristics, post-ayahuasca adverse mental states, and mental health outcomes measured by the 12-Item Short Form Survey (SF-12). On the other hand, Campagnoli et al. developed a double-blind study where they evaluated the effects of ayahuasca at two concentrations in a ritualistic context, using temporal reproduction tasks in participants with experience in ayahuasca consumption. The results revealed that the beneficial effects on the mental health of ayahuasca consumers may be related to non-pharmacological factors (placebo response) but also to pharmacological factors related to the use of ayahuasca . However, the same authors developed another study, this time a placebo-controlled naturalist observational study, where the influence of ayahuasca and the setting on changes in mental health was evaluated. Information on participants’ age, physical and mental health and history and context of ayahuasca use was collected.

The results obtained indicated that both ayahuasca drinks were mutagenic for TA98 and TA100. Thus, the results are in agreement with previous studies that support the occurrence of interhemispheric fusion in altered states of consciousness . It was found that the consumption of the substance under study led to an increase in the time of dominance both in standard conditions of binocular rivalry and with binocular rivalry, with periods of dominance being longer when drinking the beverage . Finally, Frecska et al. evaluated the effect of ayahuasca on dichotic stimulus alternation. It was found that after treatment with ayahuasca, the expression of ethanol self-administration decreased, as well as ethanol intake and preference .

As far as β-carbolines concerned, they also show potential neuroprotective effects besides their MAO-inhibiting properties18. The mechanisms through which ayahuasca produces therapeutic effects are not completely understood. An open-label clinical study found significant therapeutic benefits among patients with treatment-resistant major depressive disorder (MDD) after the administration of a single dose of ayahuasca14,15. Data from observational studies suggest that ayahuasca and its active ingredient DMT may have anxiolytic properties10,11. The ritualistic use of ayahuasca has spread throughout many countries, making it necessary to study its risks and benefits. This experience inspired her to co-found the Tierra Vida Healing Center in 2008, which later evolved into the Nimea Kaya Healing Center in 2013.

Additionally, it was found that the mice used in the study, treated with DMT, performed better in memory tests than the animals in the control group . The authors concluded that the lowest doses stimulated cell proliferation and/or had the most effective neuroprotective profile . The β-carbolines and monoterpene indole alkaloids were shown to be correlated with this property, while harmine, despite showing potent neuroprotective action in 72 h, did not present a correlation with the neuroprotection profile . After analyzing the results, it was possible to verify that the samples did not present cytotoxicity in vitro, and in three samples, the cell cyclobenzaprine mixed with alcohol viability increased after 48 h . Thus, these results are indicative that harmine can exert an anti-inflammatory effect by inhibiting the NF-kB signaling pathway . The results indicate that harmol and harmine were able to inhibit NF-kB transactivity, with the latter inhibiting NF-kB transactivity induced by tumor necrosis factor-α and lipopolysaccharides and nuclear translocation in macrophage RAW264.7 cells mouse .

However, it was also concluded that greater previous exposure to ayahuasca resulted in a decrease in disability, so the continued use of this substance may be related to neuromodulatory or compensatory effects on executive function . The study concluded that acute ingestion of ayahuasca decreased stimulus–response interference and impaired working memory . Regarding the results of the Tower of London, there was a significant increase for experienced users in resolution and execution times and in the number of movements performed .

I1 binding sites are found throughout the human brain, and the highest density areas include in the striatum, pallidum, hippocampus, amygdala, and substantia nigra . I1 sites are decreased in brains of depressed suicide victims, notably in the hippocampus and prefrontal cortex . More work into the functions of sigma receptors and their role in depression treatment is needed. Past experiments have shown an antidepressant-like effect in mice administered sigma-1 receptor agonists and attenuation of these effects with sigma receptor antagonists . These receptors are found throughout the nervous system, and are concentrated in the hippocampus, frontal cortex, and olfactory bulb, consistent with a possible role in depression . Harmine acts to decrease synaptic glutamate via increased GLT-1/EAAT2 expression and subsequently increasing glutamate transport .

NM, MU, and KO collected the data, MK and NM conducted the statistical analyses, SWT determined the concentrations of the ayahuasca components, MK, NM and KK prepared the first draft of the manuscript, and all authors discussed the results and contributed to the final author alex thompson manuscript. The original contributions presented in the study are included in the article/Supplementary Material, further inquiries can be directed to the corresponding author. That said, it could also be that highly motivated people with a positive attitude were attracted to participate, hence generalisation towards the general population is difficult for this type of studies. The strength of this study, being naturalistic, is also its greatest limitation. This is interesting to think of in light of what individuals report during a psychedelic experience.

• Further controlled and observational naturalistic studies assessing the eventual risks and potential benefits of ayahuasca are warranted.
• This finding is in line with previous research in which ayahuasca showed antidepressant effects at 7 and 21 days after its controlled administration in a clinical setting14,15,16.
• Additionally, ayahuasca may exacerbate symptoms in individuals with certain psychiatric conditions, particularly those involving psychosis.
• Osorio et al. , in an open label trial in an inpatient psychiatric unit, found that a single dose of ayahuasca has rapid acting anxiolytic and antidepressant effects in patients with recurrent depression.
• This pattern suggests that the potential therapeutic benefits of ayahuasca are temporary and do not persist in time, excepting for the case of depression.

Psychological and Emotional Effects

To understand the therapeutic potential related to these effects, further research with clinical populations is needed in which these effects can be assessed, including its link with therapeutic outcomes. Implicit emotional empathy increased at 1-week follow-up, whereas ratings of the trait neuroticism decreased. A single ayahuasca trip may not cure a person of depression , addiction, or PTSD in one fell swoop.

Ayahuasca experience are modulated by non-pharmacological factors 42,76 like set (personal disposition) and setting psilocybe semilanceata habitat (context). Despite this, the sample size and its global representativeness make the study results interesting to explore possible relationships between the studied variables. Finally, cultural and contextual variations among participants from different regions may introduce variability that affects the interpretation of findings across diverse populations. Perhaps the explanation is not based on the religious context but on the fact that the ayahuasca use was conducted in the context of a cohesive group where there is social support among members.

• Studies have shown that ayahuasca can increase levels of brain-derived neurotrophic factor (BDNF), a protein that promotes the growth and survival of neurons.
• While this can be transformative, it may also lead to confusion, fear, or difficulty integrating the experience afterward.
• Also, Santos et al. evaluated the sensitization and acute tolerance of ayahuasca in repeated doses through a double-blind, crossover and placebo-controlled clinical trial.
• In a questionnaire, 25 Northern European ayahuasca users reported increased self-awareness, being more loving, more empathetic, having greater creativity and new interests especially with nature, and having a more meaningful inner world .
• Finally, another interesting result and future topic of research is the positive relationship of experiencing visual distortion and spiritual significance with better current ayahuasca users’ mental health.

Many participants undergo deep emotional processing, reliving past traumas, suppressed emotions, or unresolved conflicts. While many find these experiences enlightening, they can also be overwhelming or frightening. As Ayahuasca alters brain chemistry, some individuals experience dizziness or a sense of physical weakness.

Intriguingly, some research has even suggested that ayahuasca might affect the brain’s physical structure. It’s a bit like ayahuasca leaving a protective force field around your neurons after the psychedelic experience has faded. One area of growing interest is ayahuasca’s potential neuroprotective properties. It’s like ayahuasca doesn’t just throw a wild party in your brain – it might actually renovate the whole house. It’s as if ayahuasca temporarily turns your brain into a more malleable, adaptable organ, primed for learning and change. Studies have shown that ayahuasca can increase levels of brain-derived neurotrophic factor (BDNF), a protein that promotes the growth and survival of neurons.

Summary Analysis

Religious experiences, such as connections with mythical entities or Gods, are also frequently reported . For instance, future placebo-controlled experimental studies could investigate potential non-pharmacological influences, while future longitudinal naturalistic research could further investigate the therapeutic potential of psychedelic drugs. Previously it has been suggested that neuroticism could lead to difficult experiences when taking a psychedelic (Barrett et al., 2017), though other studies did not show this relation (Studerus et al., 2012; Haijen et al., 2018). The fact that personality can change after a psychedelic experience has been shown previously (Griffiths et al., 2011; MacLean et al., 2011; Bouso et al., 2015; Johnstad 2021), however, most of the studies showed changes in openness which were not found in the present study. As hypothesized, the study found decreases in neuroticism 1 week after the ayahuasca ceremony; the other four traits were unaffected.

The ayahuasca fanatics might say that nothing wrong can come out of the plant and from its experience. But I had to learn to experience and view life through a different perspective. But the depression, anxiety and panic attacks were still on full power. In a matter of hours, I went from being fine and normal, to experiencing the worst depression that I had ever experienced, something that felt unreal.
