Activated Charcoal Drinks: Why We Skip Them
Jet-black lemonades and lattes made with activated charcoal are often sold as detox drinks. Here is what charcoal really does in the body, why it can get in the way of your medicines, and a dark, pretty drink to make instead.
Black lemonade, black ice cream, black lattes. Drinks colored with activated charcoal look striking in photos, and they are often sold with the promise that they soak up toxins and clean you out.
Activated charcoal is a real medical treatment, but for a very specific job: certain poisonings and overdoses, given quickly and under medical guidance. In an everyday drink it has no proven detox benefit, and it can get in the way of medicines you rely on. Here is the honest picture, plus a deep purple drink that gives you the same dramatic look without the charcoal.
What activated charcoal does
Activated charcoal works like a sponge in the stomach. It binds certain substances before they can be absorbed into the bloodstream. That is why emergency teams may use it after some kinds of poisoning or overdose.
Even in that setting, timing is everything. Cleveland Clinic notes that it works best within 30 to 60 minutes of the poisoning, and it does not bind all toxins. It is not used for every poison either. For example, it should not be used after swallowing corrosive substances such as lye, or petroleum products such as gasoline or paint thinner.
Blackberry Lemon Sparkler
You need
- fresh or thawed frozen blackberries75 g (1/2 cup)
- lemon, juiced1/2
- honey, optional1 tsp
- fresh mint leaves4 to 5
- chilled sparkling water250 ml (1 cup)
- ice cubes1 handful
Method
- Put the blackberries, lemon juice, mint and honey, if using, into a sturdy glass or small jug.
- Crush everything well with a muddler or the end of a wooden spoon until the berries release their dark juice.
- For a smooth drink, press the mixture through a small sieve into a tall glass. For a rustic drink, leave the crushed berries in.
- Add ice, then top up slowly with sparkling water and stir gently.
- Garnish with a lemon slice and a sprig of mint and serve straight away.
Tips
- For an even darker color, use very ripe blackberries or add a few blueberries.
- Do not give honey to babies under 12 months old. Leave it out or use a little maple syrup instead for older children.
- Make a jug for guests by multiplying the berries, lemon and mint, then adding sparkling water just before serving so it stays fizzy.
Why it does not belong in your daily drink
The same binding that helps in a poisoning can work against you. Cleveland Clinic lists a long series of medicines that activated charcoal may interact with, including hormonal birth control (estrogen and progestin), digoxin, carbamazepine, phenytoin and theophylline. Its medical advice is to take no other medicines, and no dairy, for at least 2 hours after a dose.
A charcoal drink you buy with lunch does not come with that advice. If you take daily medicine, including the pill, a casual charcoal latte could mean your medicine does not work as well as it should. Charcoal can also cause nausea, stomach pain, vomiting and diarrhea, and, more seriously, dehydration or a bowel blockage.
What the evidence says
There is no good evidence that charcoal drinks detox a healthy body. NCCIH, part of the US National Institutes of Health, reports that reviews found no compelling research supporting detox programs for removing toxins, and that most studies of detox approaches have been small or poorly designed.
Your body already has its own cleaning system. Cleveland Clinic explains that the liver and kidneys do most of the work of clearing harmful substances. Activated charcoal is a medicine with a narrow, important use, not a wellness ingredient.
Questions people ask
Is one charcoal latte dangerous?
It has no proven benefit, and it can cause stomach upset. The biggest concern is if you take daily medicine, including the pill, because charcoal may interfere with it.
Does activated charcoal cure a hangover?
There is no good evidence for that. Detox approaches in general have not been shown to remove toxins in healthy people, and charcoal does not bind all substances.
Should I keep activated charcoal at home for emergencies?
Only if a doctor advises it. Charcoal is not right for every poison and timing matters, so the best first step in any suspected poisoning is to call your poison center or emergency number.
