Cacao (Cocoa)

Theobroma cacao

Pronounced Cacao: kuh-KOW (also kuh-KAY-oh). Theobroma cacao: thee-oh-BROH-muh kuh-KOW.

Warm and dry, bitter and stimulating: a flavanol-rich circulatory and cerebral stimulant that rouses a cold, heavy, torpid low mood, opens stagnant peripheral and cerebral blood flow, and gently lowers blood pressure, while over-stimulating anyone already hot, tense, or wired.

At a glance

Botanical name
Theobroma cacao
Family
Malvaceae (the mallow family; the genus Theobroma was historically placed in Sterculiaceae, now folded into a broadly circumscribed Malvaceae under the APG system)
Part used
Seed (the fermented, dried, and roasted bean, source of cocoa mass, cocoa powder, and cocoa butter). The surrounding fruit pulp is also traditionally eaten and juiced, but the medicinal and nutritive material is the seed.
Taste
Bitter and astringent, with a rich, roasted, faintly aromatic depth. The bitterness comes from the methylxanthines theobromine and caffeine and from polyphenols; the drawing, drying astringency comes from the flavanol tannins (procyanidins). Pure roasted cacao is markedly bitter; the sweetness of chocolate is added sugar, not the bean itself.
Temperature
Warm. A bitter, stimulating seed whose methylxanthines rouse the circulation, heart, and nervous system and lift a cold, heavy, torpid state; the classical and Ayurvedic reading of chocolate is heating and stimulating. The warmth is kindling and dispersing rather than deeply nourishing, and it readily overheats an already hot or fiery person.
Moisture
Dry. Despite the richness of its fat (cocoa butter), the medicinal action of the seed is drying: the astringent flavanol tannins tighten and dry the tissues, and theobromine is a genuine diuretic that promotes fluid loss. It is a warming, drying, bitter stimulant, not a moistening demulcent.

Safety at a glance

In pregnancy

Possibly safe in moderate, food amounts; large or concentrated amounts are best avoided. Cocoa in the amounts commonly found in foods is regarded as possibly safe in pregnancy, but large amounts are possibly unsafe because of the caffeine and the lead and cadmium cocoa can contain. Total caffeine should be kept modest: ACOG advises less than 200 mg of caffeine per day in pregnancy, and cocoa (roughly 12 mg caffeine per tablespoon of powder, plus theobromine) counts toward that total. Concentrated cocoa-flavanol supplements in pregnancy are not well studied and are best avoided. (WebMD Cocoa monograph drawing on the Natural Medicines Comprehensive Database; ACOG guidance on moderate caffeine intake in pregnancy.)

While breastfeeding

Possibly safe in moderate, food amounts. Cocoa in ordinary food amounts is considered possibly safe while breastfeeding. Very large maternal intake is the concern: LactMed documents case reports in which mothers consuming very large quantities of chocolate or cocoa (on the order of 250 g of cocoa, or about 16 oz of chocolate, daily) had infants who became irritable, jittery, and had frequent stools from the caffeine and theobromine, resolving when intake was reduced. Keep to moderate amounts and watch the infant. (Drugs and Lactation Database (LactMed), Chocolate monograph; WebMD Cocoa monograph, Natural Medicines Comprehensive Database.)

For children

Ordinary food amounts are generally tolerated, but dark chocolate and other high-cocoa products are possibly unsafe for children in quantity because they can contain high levels of lead and cadmium, and the methylxanthine stimulant can disturb sleep and cause jitteriness, rapid heartbeat, and reflux. Favor small food amounts, avoid concentrated cacao and dark-chocolate loads and late-day intake, and choose brands tested low in heavy metals. (WebMD Cocoa monograph, Natural Medicines Comprehensive Database, on heavy-metal content in children; independent heavy-metal testing of dark chocolate, Consumer Reports, 2022 to 2023; NCCIH general caution on concentrated botanicals in children.)

Cautions

Cacao is a methylxanthine stimulant (theobromine, with smaller amounts of caffeine) and can cause insomnia, restlessness, anxiety, jitteriness, rapid or irregular heartbeat, and reflux, especially in sensitive people, children, and with large or late-day intake. It is a recognized migraine trigger for some people. Cocoa and cocoa powder, particularly dark chocolate and some raw cacao, can carry notable lead and cadmium, a concern with heavy or long-term use and in children. Its oxalate content is relevant to calcium-oxalate kidney-stone formers, and its methylxanthines can irritate the bladder in interstitial cystitis. Sweetened chocolate is high in sugar and fat. Theobromine is toxic to dogs and other pets, so keep it out of their reach.

General contraindications

Pregnancy and breastfeeding at large or concentrated doses (caffeine, theobromine, and heavy metals; keep total caffeine modest). Children in large amounts of dark or high-cocoa products (heavy metals and stimulant sleep disturbance). Anxiety, insomnia, cardiac arrhythmia or palpitations, uncontrolled hypertension, and gastroesophageal reflux, all of which a stimulant can worsen. Migraine-prone individuals for whom cacao is a trigger. Calcium-oxalate kidney stones and interstitial cystitis. Concurrent MAOI antidepressants (tyramine content), other stimulants, theophylline, and pharmacologic cardiac stress testing with adenosine or dipyridamole.

Stewardship

Theobroma cacao is a widely cultivated tropical crop and is not a wild-at-risk species (not listed by United Plant Savers). The real stewardship concerns are ethical and ecological: cocoa production drives tropical deforestation, especially in West Africa, and is linked to child and forced labor, while heirloom criollo genetics are dwindling. Choose Fair Trade, Rainforest Alliance, or equivalently certified, shade-grown, and where possible organic cacao, and favor origins and brands that test low for cadmium and lead.

In the traditional record

Not named in the canonical biblical texts. Cacao is a New World plant, unknown to the ancient Mediterranean and biblical world; it is native to tropical Central and South America and was a sacred and ceremonial plant of the Maya and Aztec, for whom it was a ritual beverage, a medicine, and a currency. Its botanical name Theobroma, food of the gods, coined by Linnaeus in 1753, preserves that Mesoamerican reverence rather than any scriptural reference.
