1. Who Was Vittorio Erspamer?
Before we examine the peptides, we need to understand the man who identified them.
Vittorio Erspamer (1909–1999) was one of the most prolific pharmacologists of the 20th century. He discovered serotonin — yes, the same neurotransmitter now central to modern psychiatry and antidepressant pharmacology. He was nominated for the Nobel Prize in Medicine twice. He spent decades cataloguing the bioactive compounds found in amphibian skin secretions, identifying hundreds of novel peptides across dozens of species.
When Erspamer turned his attention to Phyllomedusa bicolor — the Giant Monkey Frog of the Amazon — he found something that stopped him in his tracks. No other amphibian species had produced a secretion with this density and diversity of bioactive compounds. He identified 16 distinct peptides, each with measurable pharmacological activity, each interacting with different receptor systems in the human body.
“A fantastic chemical cocktail with potential medical applications unlike anything else in nature.”
— Vittorio Erspamer
This is the scientific foundation of Kambo.
2. What Is a Bioactive Peptide?
A peptide is a short chain of amino acids — the building blocks of proteins. When a peptide is described as bioactive, it means it has a measurable biological effect when it interacts with the body's receptor systems.
Think of receptors as locks and peptides as keys. Each peptide has a specific shape that fits specific receptor locks — triggering specific biological responses. Some peptides are analgesic. Some are vasodilatory. Some are antimicrobial. Some interact with the brain's mood-regulating systems.
The Key Insight
What makes Kambo extraordinary is not any single peptide — it is the simultaneous activation of multiple receptor systems by 16 different peptides working in concert. No pharmaceutical drug does this. No synthetic compound has replicated it.
3. The Opioid Peptides — Pain, Mood & Euphoria
Dermorphin
Dermorphin was first isolated from Phyllomedusa sauvagei by Erspamer's team in 1981 and subsequently identified in Phyllomedusa bicolor. It is a heptapeptide — a chain of just seven amino acids — that binds with extraordinary selectivity to mu-opioid receptors.
Mu-opioid receptors are the same receptors targeted by morphine, codeine, and fentanyl. The difference is potency and selectivity. Dermorphin's binding affinity is so high that pharmaceutical researchers have been studying it for decades as a potential pain management compound — one that could deliver morphine-level analgesia at a fraction of the dose.
In Kambo: Dermorphin is the primary contributor to the post-ceremony euphoria and sense of profound wellbeing that many participants report. It is also why the active phase, despite its intensity, is followed by a feeling of deep calm and pain relief.
Pharmaceutical research: Multiple patents pending on dermorphin derivatives for chronic pain management and opioid-sparing analgesia.
Deltorphin I & II
Where dermorphin targets mu-opioid receptors, deltorphins I and II target delta-opioid receptors with extraordinary selectivity. This distinction matters enormously in pharmacology.
Delta-opioid receptor activation is associated with:
- Mood enhancement and anxiolytic (anti-anxiety) effects
- Analgesic properties without the respiratory depression associated with mu-opioid agonists
- Potential neuroprotective effects
- Reduced addiction liability compared to mu-opioid agonists
In Kambo: Deltorphins contribute to the mood-lifting, anxiety-reducing effects reported in the days following a ceremony. They work alongside dermorphin to create the characteristic post-ceremony state — clear, calm, emotionally lighter.
Pharmaceutical research: Among the most studied Kambo peptides. Their selectivity for delta-opioid receptors makes them valuable research tools and potential therapeutic leads for depression, anxiety, and chronic pain without addiction risk.
4. The Cardiovascular Peptides — Blood Pressure & Circulation
Phyllokinin
Bradykinin-related vasodilatory peptidePhyllokinin is structurally related to bradykinin — a peptide involved in blood pressure regulation and inflammation. It causes blood vessels to relax and widen (vasodilation) and increases the permeability of blood vessel walls.
In Kambo: Phyllokinin is responsible for two of the most visible physical responses: facial swelling (increased vascular permeability causes fluid to move into facial tissues) and blood pressure drop (vasodilation reduces peripheral resistance). This is why cardiovascular monitoring is essential during Kambo ceremonies.
Bradykinin Potentiating Peptides
This is one of the most consequential discoveries in Kambo research — not for Kambo itself, but for modern medicine.
Erspamer's team identified peptides in Phyllomedusa bicolor that potentiate bradykinin activity — meaning they enhance and prolong the effects of bradykinin in the body. These peptides inhibit the enzyme ACE (Angiotensin-Converting Enzyme), which normally breaks down bradykinin.
The discovery of bradykinin-potentiating peptides in amphibian secretions directly inspired the development of ACE inhibitor drugs — now among the most widely prescribed cardiovascular medications in the world.
In Kambo: These peptides contribute to the cardiovascular response — vasodilation, blood pressure reduction, and increased circulation. They are also why Kambo is absolutely contraindicated for anyone already taking ACE inhibitors or blood pressure medication.
T-Kinin
Hypotensive kinin peptideT-kinin is a hypotensive peptide — it lowers blood pressure. It works synergistically with phyllokinin and the bradykinin-potentiating peptides to produce the cardiovascular response characteristic of Kambo.
In Kambo: T-kinin contributes to the temporary drop in blood pressure during the active phase. This is why participants are always seated or lying down during a ceremony — standing during this phase risks fainting.
5. The Gastrointestinal Peptides — The Purge Explained
The purge is the most misunderstood aspect of Kambo. It is not the goal. It is not a “detox flush.” It is a pharmacologically driven gastrointestinal response triggered by specific peptides acting on specific receptors. Understanding this changes everything about how you approach a ceremony.
Phyllocaerulein
Phyllocaerulein is structurally similar to cholecystokinin — a hormone that regulates digestion, appetite, and the release of digestive enzymes. It stimulates the adrenal cortex and pituitary gland and is the primary driver of nausea and purging in Kambo.
When phyllocaerulein binds to CCK receptors, it triggers:
- Contraction of the gallbladder
- Release of pancreatic enzymes
- Stimulation of gastric motility
- Nausea and vomiting
In Kambo: This is the peptide most responsible for the purge. It is not water volume that drives the purge — it is phyllocaerulein acting on the gastrointestinal system. This is why excess water consumption does not deepen the ceremony — it only increases hyponatremia risk.
Caerulein
Neuropeptide / CCK analogueCaerulein amplifies the gastrointestinal response initiated by phyllocaerulein. It stimulates the release of gastric acid, bile, and pancreatic enzymes — essentially triggering a comprehensive digestive reset.
In Kambo: Caerulein works alongside phyllocaerulein to produce the full purge response. It also contributes to the digestive clarity many participants report in the days following a ceremony.
Bombesin
Bombesin was first isolated from the European fire-bellied toad (Bombina bombina) and subsequently identified in Kambo. It stimulates gastric acid secretion and smooth muscle contraction throughout the gastrointestinal tract.
Beyond Kambo: Bombesin receptors are overexpressed in several types of cancer cells, making bombesin and its analogues active subjects of research for tumour imaging and targeted cancer therapy. Radiolabelled bombesin analogues are being studied as diagnostic and therapeutic agents for prostate, breast, and lung cancers.
Bombesin Nonapeptide
Shorter bombesin variantA structurally shorter variant of bombesin with similar receptor binding and gastrointestinal effects. Works synergistically with bombesin and caerulein in the purge response.
Phyllolitorin
Bombesin-like peptideStimulates gastric smooth muscle contraction. Contributes to the intestinal cleansing effect and works as part of the broader gastrointestinal peptide complex in Kambo.
6. The Neuroactive Peptides — Brain, Mood & Nervous System
Sauvagine
CRF-related peptideSauvagine interacts with the hypothalamic-pituitary-adrenal (HPA) axis — the body's central stress response system. It triggers cortisol release from the adrenal glands and has stimulant effects on the colon.
In Kambo: Sauvagine contributes to the acute stress response of the active phase — the elevated heart rate, the sense of intensity, the activation of the body's emergency systems. It also contributes to the blood pressure drop and is relevant to the hyponatremia risk through its effects on fluid-regulating hormones.
Research: Studied for its potential in treating stress-related disorders and its interactions with the HPA axis — the same system implicated in PTSD, depression, and anxiety disorders.
Adenoregulin
Adenosine receptor modulatorAdenoregulin interacts with adenosine receptors — a class of receptors involved in sleep regulation, mood, and neuroprotection. Adenosine receptors are also the target of caffeine (which blocks them, producing alertness) and are implicated in depression and anxiety disorders.
In Kambo: Adenoregulin may be one of the key contributors to the sustained mood-lifting effects reported by participants in the days and weeks following a ceremony. Its interaction with adenosine receptors could explain why many people with depression or anxiety report significant improvement after Kambo.
Research: Adenosine receptor modulators are an active area of research for depression, anxiety, and neurodegenerative conditions.
Phyllomedusin
Tachykinin peptidePhyllomedusin is a tachykinin — a family of neuropeptides that affect smooth muscles throughout the body. It stimulates salivary glands, tear ducts, and intestinal smooth muscle.
In Kambo: Phyllomedusin is responsible for several of the more unusual physical responses during a ceremony — increased salivation, tear production, and intestinal contractions. It contributes to the full-body nature of the Kambo response.
Neurokinin B
Tachykinin neuropeptidePart of the tachykinin family, involved in neurological signalling across multiple body systems and reproductive hormone regulation. Contributes to the broad neuroactive profile of Kambo.
Preprotachykinin Peptides
Tachykinin precursorsPrecursor peptides processed by the body into active tachykinin compounds. Part of the biochemical complexity that makes Kambo difficult to replicate synthetically.
7. The Antimicrobial Peptides — The Immune Connection
Dermaseptins
The dermaseptins are a family of antimicrobial peptides — not a single compound but a group of related peptides with broad-spectrum antimicrobial activity. They have demonstrated activity against:
Bacteria
Including antibiotic-resistant strains
Fungi
Including Candida species
Parasites
Including Leishmania and Trypanosoma
Enveloped Viruses
Including herpes simplex
Why This Matters
In an era of rising antibiotic resistance, antimicrobial peptides are one of the most active areas of pharmaceutical research. Dermaseptins from Phyllomedusa species are among the most studied, with multiple research groups investigating their potential as novel antibiotic leads.
In Kambo: The dermaseptins contribute to the immune-related effects some participants report — reduced susceptibility to illness, faster recovery from infections, and general immune resilience in the weeks following a ceremony. These are reported effects, not medical claims.
8. Why Synergy Is Everything
This is the most important section of this entire article.
Every pharmaceutical company that has studied Kambo has attempted the same thing: isolate the most potent peptide, synthesise it, patent it, sell it.
None have succeeded in replicating the full effect of the natural secretion.
The reason is synergy.
When you administer dermorphin alone, you get opioid analgesia — and opioid side effects. When you administer phyllocaerulein alone, you get nausea and purging — without the mood effects. When you administer sauvagine alone, you get a stress response — without the resolution.
But when all 16 peptides are present simultaneously — as they are in the natural secretion — something different happens. The peptides modulate each other's effects. The opioid peptides soften the intensity of the gastrointestinal response. The cardiovascular peptides regulate the stress response. The neuroactive peptides create the conditions for the post-ceremony clarity.
The whole is genuinely greater than the sum of its parts.
This is why Jason Fellows describes Kambo as “the original peptide therapy” — and why over 70 pharmaceutical patents are pending without a single successful synthetic replication of the full effect.
The synergistic interaction of all 16 peptides is what makes Kambo unique. It is also why the natural secretion, administered by a trained practitioner with proper protocols, remains the only way to access this effect.
9. What Pharmaceutical Research Tells Us
The pharmaceutical interest in Kambo peptides is not speculative — it is documented and ongoing:
| Peptide | Research Area | Status |
|---|---|---|
| Dermorphin | Chronic pain, opioid-sparing analgesia | Multiple patents pending |
| Deltorphin | Depression, anxiety, addiction | Active research |
| Dermaseptins | Antibiotic resistance, antifungal | Multiple patents pending |
| Bombesin analogues | Cancer imaging and therapy | Clinical research stage |
| Bradykinin potentiators | Cardiovascular disease | Already in clinical use (ACE inhibitors) |
| Adenoregulin | Depression, neurodegenerative disease | Early research |
| Sauvagine | Stress disorders, HPA axis | Active research |
The fact that pharmaceutical companies are investing heavily in synthesising these compounds is the strongest possible validation of their biological activity. These are not folk remedies. These are pharmacologically active compounds that the world's most sophisticated drug development organisations are trying to replicate.
