Cacao Ceremony

Archaeological evidence for early cacao use

Residue studies place cacao use in the Americas thousands of years before the modern ceremony. Zarrillo and colleagues (2018) reported cacao starch grains, absorbed theobromine and ancient DNA from about 5,300 years ago at the Santa Ana-La Florida site in southeast Ecuador, which they described as the earliest evidence of Theobroma cacao use in the Americas and as pointing to the upper Amazon as the oldest known center of domestication.

In Mesoamerica, Henderson and colleagues (2007) found theobromine or caffeine in 11 of 13 pottery sherds from Puerto Escondido in what is now Honduras, with the earliest after 1150 BCE. They proposed that the earliest drinks were made from the sweet pulp around the seeds rather than from ground seeds, while noting that theobromine and caffeine occur in both, so the chemistry cannot settle which part was used.

Olmec and Maya contexts

Powis and colleagues (2011) tested 156 sherds from San Lorenzo, an Olmec center on the Gulf Coast of Mexico, and found 27 theobromine-positive samples spanning roughly 1800 to 1000 BCE across storage, serving and drinking vessels. In one elite burial context, four of eleven tested vessels were positive; the authors interpreted this as cacao served in ceremonies after interment, and they caution that the small sample limits wider generalization.

Ford and colleagues (2022) analyzed 54 Late Classic (600 to 900 CE) sherds from residential and civic contexts at El Pilar on the Belize-Guatemala border and found a cacao marker, theophylline, in 30 (56%) of them, across all contexts. They argued that earlier studies focused on ornate elite vessels and that cacao reached Maya residents beyond the elite.

Living Maya practice and colonial-era records

Kufer, Grube and Heinrich (2006) describe cacao as a ritual food plant that in many Maya groups ranks second only to maize, and report that the Ch'orti' Maya of eastern Guatemala use it in rain ceremonies tied to local environmental knowledge. Dillinger and colleagues (2000) review colonial sources, including the Badianus Codex (1552) and the Florentine Codex (1590), and report more than 100 medicinal uses of cacao in manuscripts from the 16th to early 20th centuries.

The modern ceremony

The group practice now called a cacao ceremony is documented as a recent, mainly non-Indigenous development. In a 2021 University of Oregon folklore thesis, Burby reports that sacramental cacao use became popular over the previous two decades, drawing on surveys of 118 participants and attendance at online and in-person ceremonies. About a quarter of interviewed participants credited the practice to a single American cacao company founder, while the rest pointed generally to Central and South American Indigenous practice. The thesis is a graduate study of three companies' communities, not a survey of all facilitators.

Cacao, cocoa and chocolate

Burby notes that Linnaeus named the genus Theobroma, Greek for food of the gods, in 1753, and that linguists trace the word cacao to a proto-Mixe-Zoquean loan word, kakawa, later kakaw in Maya languages. Dillinger and colleagues instead describe the word as derived from Olmec and subsequent Mayan languages, so the Olmec language attribution is not settled in these sources. English usage varies, and sources in this article use cocoa for the processed product and cacao for the plant and seed.

Cacao ceremony and ceremonial cacao

Cacao ceremony and ceremonial cacao are modern English terms. Burby reports that a U.S. cacao company founder says he popularized both phrases and the label ceremonial grade, and that competitors now use them. The sources reviewed do not define ceremonial grade as a technical or regulated standard, and Burby treats it as language used by sellers and practitioners. The term should be distinguished from historical Mesoamerican cacao drinks, which Burby, citing earlier scholarship, says were consumed as liquids, including a cold Aztec drink and a Maya hot drink.

Neo-shamanic framing

Burby situates the ceremonies within neo-shamanism and the New Age, where practitioners describe cacao as an entheogen, a plant medicine or a spirit. The thesis presents these as participants' and facilitators' own categories. Historical and pharmacological sources in this article do not use that framing, and neither do the archaeological studies of residues.

Format described by ethnographers

Burby describes ceremonies, held online or in person, that typically include an opening of the space, setting of intentions, a shared drink of cacao, guided meditation, sound or movement, journaling and group sharing. Facilitators range from company founders to independent practitioners, and many events follow the moon cycle or a set weekday. Some facilitators adapt invocations from Guatemalan elders, and some participants told Burby they left groups whose leaders did not share cacao's history.

The description above covers the general structure only. The sources reviewed do not set out standard preparation methods, quantities or protocols, and this article does not give them.

What practitioners describe

Practitioners and sellers quoted by Burby describe cacao as a gentle spirit or teacher with heart-opening and grounding qualities. They also point to compounds such as theobromine, phenylethylamine and anandamide as contributors to feelings of love, energy and openness. These are practitioners' explanations and are separate from the pharmacology reviewed later in this article.

Living Mesoamerican drinks

Cacao drinks have continued in Mesoamerican communities outside the wellness setting. The Ch'orti' rain ceremonies described by Kufer and colleagues, in which cacao is used in agrarian ritual alongside local environmental knowledge, are an example. The sources reviewed do not describe these Indigenous practices as equivalent to the modern group ceremony, and this article does not describe restricted knowledge.

Reasons participants give

In Burby's survey of 118 participants in ceremonies run by three companies, 58.5% said they consume cacao to connect with others through ceremony. In 36 write-in answers, 27.7% mentioned taste, and about 22% each mentioned access to divine wisdom, a healthy mood booster that replaces coffee, or an alternative medicine for symptoms such as anxiety, depression and premenstrual syndrome. One participant said they had discontinued all Western treatments and used cacao for autoimmune disease.

Historical medicinal claims

Dillinger and colleagues report that colonial and later manuscripts recommended cacao to restore weight, stimulate apathetic or exhausted patients and aid digestion, and that chocolate paste served as a vehicle for bitter medicines. These are records of historical belief and practice, and the review does not test whether the uses were effective.

Ceremony-specific research

No controlled study of a cacao ceremony as a health intervention was found in the sources reviewed. A PubMed search for the phrase cacao ceremony on 2026-10-06 returned eight records, covering archaeology, nutrition and psychology, and none was a clinical study of a ceremony. The ceremony literature located is ethnographic and describes participants' experiences and beliefs.

Constituents of cacao

Smit (2011) reviews the pharmacology of cocoa and concludes that the effects of theobromine in people are under-researched. He judges caffeine the most convincing candidate among constituents proposed to explain why people like chocolate, though a role for theobromine cannot be ruled out. He considers most other constituents unlikely to have a psychopharmacological effect because of very low concentrations or because they do not reach the brain. This review is of chocolate and cocoa foods, not ceremonial preparations.

Cocoa flavanols and cardiovascular outcomes

The Cochrane review by Ried and colleagues (2017) pooled 35 randomized trials (40 treatment comparisons, 1,804 mainly healthy adults) of flavanol-rich cocoa or chocolate lasting 2 to 18 weeks, with a mean of about 9 weeks. It found small reductions in systolic and diastolic blood pressure, each about 1.8 mmHg, and rated the evidence moderate because of unexplained heterogeneity, with some sign of reporting bias in industry-linked trials.

The COSMOS randomized trial (Sesso and colleagues, 2022) gave 21,442 older US adults a cocoa extract providing 500 mg of flavanols daily or placebo for a median of 3.6 years. Total cardiovascular events did not differ significantly (hazard ratio 0.90, 95% CI 0.78 to 1.02), while cardiovascular death, a secondary outcome, was lower (HR 0.73). These results concern a standardized extract and do not apply to ceremonial drinks.

Mood and cognition

Scholey and Owen (2013) systematically reviewed chocolate and cocoa constituents and mood. Of eight studies on mood, five reported improved mood or less negative mood, and of eight on cognition, three showed clear cognitive enhancement. The authors state that it is unclear whether mood effects come from the sensory properties of chocolate or from its pharmacology. The review did not test group ceremonies.

Appropriation and commerce

Burby notes that scholars may view ritualized cacao consumption as an appropriated trend, comparable to marketing of single-origin craft coffee, and that selling ceremonial-grade cacao can be read as marketing that exoticizes the people who produce it. He also reports that the three companies he studied publicly discuss colonialism and appropriation, partner with Maya cooperatives or reforestation groups, and that one founder states he is not a Maya shaman. Burby says the question of appropriation deserves its own study, and the sources reviewed do not include Indigenous Maya commentary on the ceremony.

Sources and sourcing

Burby reports that sellers advertise cacao made by Maya families in Guatemala, and that participants value knowing its origin. Claims of an original or ancient recipe are reported only as marketing statements in the thesis, and this article does not verify them.

Stimulant effects and tolerability

Cocoa contains theobromine and caffeine. The Cochrane review reported that adverse effects in trials were infrequent: gastrointestinal complaints in 8 of 760 people taking cocoa (1%) versus 3 of 754 controls (0.4%), plus a few reports of headache and jitteriness. One trial reported laxative effects from high theobromine content, and another study cited by the review, using 850 to 1,000 mg of theobromine, reported nausea, vomiting, headache and diarrhea. Smit notes that animal toxicity findings cannot be directly extrapolated to people but that domestic animals need protection from chocolate and cocoa foods.

Medicines and medical conditions

Van den Eynde, Gillman and Blackwell (2022), reviewing the diet for people taking classic monoamine oxidase inhibitors, report tyramine levels of 3 mg/kg or less in several chocolate samples, and cocoa products are not among the foods they flag as risky. They also note that stimulants such as caffeine may have an exaggerated effect in people taking these drugs, and they cite a case of coffee-induced hypertension on tranylcypromine. The review does not assess ceremony-scale quantities. People who take antidepressants or other prescription drugs, or who have heart rhythm, blood pressure or anxiety problems, should ask their prescriber or pharmacist about stimulants.

Pregnancy and caffeine

Lyngsø and colleagues (2017) pooled observational studies of coffee and caffeine and found higher risk of spontaneous abortion at 300 mg of caffeine daily (relative risk 1.37) and 600 mg daily (relative risk 2.32), while noting little association with fertility. This evidence concerns caffeine rather than cacao, and the sources reviewed do not quantify caffeine in ceremonial cacao, so no figure for cacao can be drawn from them.

Cadmium and lead

Abt and Robin (2020), writing from the U.S. Food and Drug Administration's food safety center, report that cocoa and chocolate can contain cadmium and lead from natural and human sources, with higher cadmium observed in some cocoa originating from parts of Latin America. They say mitigation methods are still being identified. The review is about cocoa and chocolate products in general, and it does not address ceremonial cacao specifically or give a safe level for it.

Care boundaries

A cacao ceremony is not a medical treatment. Burby's survey includes a participant who stopped conventional treatment for an autoimmune condition, and no source reviewed supports using cacao in place of medical care for any condition. Anyone with a medical condition, taking medication, pregnant or breastfeeding should check with a clinician, and necessary care should not be delayed or replaced.
