Cocoa and dark chocolate: traditional uses, forms and sensible limits

Cocoa is not just a sweet. Behind the bar sits a bean packed with polyphenols, magnesium, potassium and theobromine, prized in Mesoamerica long before it reached Europe. This page looks at what herbalists and naturopaths make of cocoa, which forms are worth keeping in the cupboard, how to use them through the day, and who should go carefully.

A short history of the bean

• Cocoa was cultivated by Mesoamerican peoples — Olmec, Maya and Aztec — from around 1500 BC.
• Remains of large cocoa plantations, some six centuries old, have been uncovered in the Yucatán Peninsula in Mexico.
• The cocoa tree was treated as a sacred tree, and the beans served as both drink and currency.
• The bean reached Europe in 1528, first as a bitter spiced drink, long before it became a confection.

What it is credited with

• Mesoamerican tradition drank cocoa as a strengthening and stimulating beverage, taken before effort or ceremony.
• Naturopathy credits cocoa, thanks to its magnesium content, with a reputation as an anti-fatigue food during demanding periods.
• Herbalists commonly suggest a small square of high-cocoa chocolate as a comforting pick-me-up when spirits and energy are flat.
• Cocoa has a long-standing reputation as a mood food, and is traditionally offered in times of stress and nervous tension.
• Traditional practice associates a cocoa-rich diet with support for the heart and circulation, which is why dark chocolate rather than milk chocolate is the form recommended.
• In old household use, cocoa husk infusion was drunk as a warming evening drink for those who wanted the aroma without a strong stimulant.
• Cocoa butter is used in traditional skincare as a rich emollient for dry hands, elbows, heels and lips.
• Cocoa powder is valued in naturopathic cooking as a bitter note, since bitter flavours are traditionally said to wake up the appetite.

How to use it

The rule of thumb in herbal kitchens is simple: the more cocoa, the more bitter, and the more polyphenols. Choose dark chocolate at 70% cocoa or above, or work with unsweetened powder and nibs.

The daily square

• One or two small squares of dark chocolate, eaten slowly so the bitterness comes through.
• Best after a meal, or as a mid-afternoon snack when energy dips.
• Taken as a regular habit alongside a balanced diet, not as an occasional large slab.
• Keep it away from the evening if you are sensitive to stimulants.

Hot cocoa, the plain way

• Whisk a heaped spoonful of unsweetened cocoa powder into a mug of hot milk or plant milk.
• Let it stand two or three minutes so the powder swells and loses its raw edge.
• Sweeten lightly with honey only once the drink has cooled a little.
• A pinch of cinnamon, chilli or vanilla is the traditional Mesoamerican pairing.

Nibs and cooking

• Scatter a spoonful of crushed nibs over porridge, yoghurt or baked fruit for crunch and bitterness.
• Add a teaspoon of unsweetened cocoa to chilli, bean stews or a meat marinade — a classic savoury use.
• Blend cocoa powder with banana and a little milk for a quick drink before exercise.

Cocoa husk infusion

• Steep a small handful of cocoa bean shells in freshly boiled water, covered, for about ten minutes.
• Strain and drink plain; the taste is chocolatey but light, with much less stimulant than the bean.
• Keep it as a short evening ritual over a week or two rather than an all-day drink.

Cocoa butter on the skin

• Warm a pea-sized piece between the fingers until it melts, then massage into dry patches.
• Apply at night on heels and elbows, under socks or a loose sleeve.
• Store it out of the sun, since it softens quickly in warmth.

Frequently Asked Questions

The one thing to remember: choose dark chocolate at 70% cocoa or more, eat one or two squares slowly and regularly, and keep it away from bedtime.

Why does everyone insist on 70% cocoa?

Because the polyphenols come from the bean, not the sugar or the milk. The higher the cocoa content, the more flavanols and minerals in the same mouthful. Below about 70%, you are mostly eating sugar and fat.

How much should I eat in a day?

Traditional practice favours little and often: one or two small squares, taken as a habit rather than a treat binge. Eating a whole bar undoes the point, and cocoa in quantity can cause digestive upset or trigger a migraine in sensitive people.

Is cocoa powder as good as chocolate?

Unsweetened cocoa powder gives you the bean without the added sugar, which makes it a useful everyday form. Whisk it into hot milk, or stir a teaspoon into a bean stew or marinade. The taste is far more bitter than a bar, so start with a little.

Can I drink cocoa in the evening?

Cocoa contains theobromine and some caffeine, so a strong cup late at night can keep light sleepers awake. If you want the flavour without the kick, try an infusion of cocoa bean husks instead. Children in particular do better with cocoa drinks earlier in the day.

Can dogs have a little chocolate?

No. Theobromine is toxic to dogs, and also to cats and horses. Store chocolate, nibs and cocoa husk products where pets cannot reach them, and contact a vet at once if an animal eats any.
