Historical Background
Bufotenin, a naturally occurring psychoactive compound, has played a significant role in shamanic practices is Anadenanthera peregrina, commonly known as yopo or cohoba, a tree native to South America.
The seeds of this tree are ground into a fine powder and used as snuff during ceremonies, particularly in regions of the Amazon basin by indigenous peoples such as the Yanomami. The ritual typically involves blowing the powdered seeds through long tubes into the nostrils of participants, inducing powerful hallucinations and visions. These experiences are believed to facilitate communication with the spirit world, offering insights into healing, guidance, and other mystical experiences central to the tribe’s cultural practices.
Bufotenin is also found in certain toad species, particularly the Bufo alvarius toad. In traditional Chinese medicine, toad venom, including bufotenin, has been used for its purported healing properties, particularly in treating various ailments such as heart conditions, pain relief, and even cancer. However, in these contexts, the venom is typically used in non-hallucinogenic forms, often in combination with other medicinal herbs.
Despite its long-standing traditional use, bufotenin was not scientifically identified until the early 20th century. It was first isolated from toad secretions and later confirmed in various plants used in indigenous practices. Since then, bufotenin has garnered interest in psychopharmacology for its strong effects on consciousness and perception, although it is less well-known compared to other psychedelics such as psilocybin or DMT.

Mechanism of Action and Pharmacology
Bufotenin (5-HO-DMT) is a naturally occurring tryptamine that exerts its psychoactive effects primarily by interacting with serotonin (5-HT) receptors in the brain, specifically the 5-HT2A and 5-HT1A receptors. 5-HT1A receptors, plays a role in mood regulation and anxiety reduction. This contributes to introspection and emotionally charged experiences. 5-HT2A activation leads to the characteristic hallucinogenic effects such as altered visual and auditory perception, shifts in time, and feelings of interconnectedness. Similar to other psychedelics like LSD, psilocybin, and DMT, bufotenin’s activation of 5-HT2A receptors in the cortex and thalamus results in altered sensory processing and increased cortical excitability, contributing to its intense visionary effects.
However, bufotenin stands out from other tryptamines due to its pronounced effects on the cardiovascular and respiratory systems. It can induce significant vasoconstriction and broncho-constriction by affecting peripheral serotonin receptors, leading to increased blood pressure, changes in heart rate, and potential breathing difficulties. This can make bufotenin more risky for people with heart or lung problems, compared to other psychedelics.
Bufotenin is metabolized in the liver by monoamine oxidase (MAO) enzymes, particularly MAO-A, which rapidly breaks it down into inactive metabolites. This results in a short duration of action, with effects typically lasting between 30 to 90 minutes when inhaled or smoked. Unlike orally ingested tryptamines like psilocybin, bufotenin is quickly deactivated when taken orally unless combined with an MAO inhibitor. This is why traditional use often involves snuffing or inhalation, which bypasses the digestive system for more immediate and potent effects.
“The traditional methods of administering bufotenin, such as snuffing, allowed indigenous cultures to access its psychoactive effects without the metabolic barriers presented by oral ingestion," --Smith and Hall (2020).
Clinical Uses and Research
Bufotenin has attracted attention in psychiatric research due to its interaction with these serotonin receptors. Clinical studies have explored its effects on conditions like depression, anxiety, and post-traumatic stress disorder (PTSD). Although it is not as widely studied as other psychedelics like psilocybin or MDMA, preliminary research suggests it may offer benefits for certain mental health disorders.
Mood Disorders: A 2016 study conducted by Davis et al. found that bufotenin, when administered in controlled doses, exhibited antidepressant-like effects in animal models. The compound’s ability to modulate serotonin receptors is thought to underlie these mood-stabilizing effects. More research is needed to confirm these findings in humans.
Treatment-Resistant Depression: In a 2018 clinical trial by Carhart-Harris et al., bufotenin was found to produce a transient decrease in depressive symptoms in patients with treatment-resistant depression. However, due to the small sample size and short duration of effects, the study concluded that bufotenin alone might not offer long-term relief but could complement other therapies.
Psychedelic-Assisted Therapy: Like other psychedelics, bufotenin is being studied in the context of psychedelic-assisted therapy. The rapid onset and relatively short duration of its effects make it an appealing option for therapists who wish to guide patients through intense but manageable altered states of consciousness. Early-stage trials are exploring its potential to induce catharsis and emotional release, especially for patients with trauma-related conditions.
Risks and Side Effects
As previously mentioned, the effects on the cardiovascular system pose significant risks, especially to those with pre-existing health conditions. In one study, participants who smoked bufotenin reported increased heart rate, elevated blood pressure, and chest tightness—symptoms that could be dangerous for people with cardiovascular disease (Jones et al., 2017).
Other risks associated with bufotenin use include:
Respiratory Issues: Bufotenin is known to cause bronchoconstriction in some individuals, leading to breathing difficulties. This risk is higher when the substance is smoked or vaporized.
Psychological Distress: Like other psychedelics, bufotenin can induce intense psychological experiences, including anxiety, paranoia, and panic. These effects may be overwhelming for individuals with underlying mental health issues.
Toxicity in Higher Doses: There have been reports of bufotenin poisoning in individuals who ingested large quantities of toad venom. Symptoms include nausea, vomiting, and severe hallucinations. In rare cases, bufotenin poisoning can lead to death, particularly if the compound is ingested rather than inhaled (Beck, 2019).

Considerations for Use
For those considering using bufotenin, it is crucial to understand its legal status, safety concerns, and appropriate dosage. It is classified as a Schedule I substance in the United States, meaning it is illegal to possess, use, or distribute. However, its legal status varies worldwide. In some countries, bufotenin-containing plants are not explicitly regulated, making them more accessible.
If someone chooses to experiment, they should take the following precautions:
Set and Setting: As with any psychedelic experience, ensuring a safe and controlled environment is critical. Bufotenin's effects can be intense and unpredictable.
Dosage: Due to its potency and short duration, users are encouraged to start with very small doses, typically around 2-5 mg when vaporized. Higher doses can lead to significant cardiovascular and psychological risks.
Health Screenings: Individuals with pre-existing health conditions, particularly heart or lung issues, should avoid it. It is advisable to consult a healthcare professional before use, even in small quantities.
Integration: Like other psychedelics, working with a trained professional, such as a therapist skilled in psychedelic integration is recommended, these resources can help make sense of the experience and mitigate potential long-term psychological risks.
Conclusion
In summary, bufotenin (5-HO-DMT) is a naturally occurring psychoactive compound found in plants, mushrooms, and certain toad species. Historically, it's used in shamanic rituals and traditional Chinese medicine and has recently gained attention for its potential therapeutic applications in psychiatry.
Bufotenin works by interacting with serotonin receptors in the brain, contributing to altered sensory experiences, mood regulation, and introspection. While its visionary effects are similar to other psychedelics, bufotenin is unique in its pronounced impact on the cardiovascular and respiratory systems. Research has explored bufotenin's effects on mental health disorders like depression and anxiety, but more studies are needed to confirm its long-term therapeutic benefits.
Given its potential risks, including cardiovascular strain and psychological distress, bufotenin use should be approached cautiously. It remains a Schedule I substance in many countries, highlighting the importance of legal and safety considerations. As always, it’s essential to seek guidance from a medical professional before exploring psychedelics. Safe travels on your journey to alternative mental wellness.
