Rating (out of 5): 1

Activated charcoal has a long history of traditional use for digestive complaints, including colic in adults, primarily due to its well-known ability to adsorb gases and toxins in the gastrointestinal tract. In various folk and alternative medicine systems, activated charcoal has been recommended to relieve symptoms such as bloating, flatulence, and abdominal discomfort, all of which can be associated with colic. The rationale is that activated charcoal’s porous structure can trap gas-producing substances or toxins, thus reducing symptoms. However, while this traditional use is widespread, scientific studies investigating the efficacy of activated charcoal specifically for adult colic are limited. Some small clinical trials have suggested a potential benefit of activated charcoal in reducing intestinal gas, but results are inconsistent and often methodologically weak. Authoritative reviews and clinical guidelines do not generally recommend activated charcoal for routine management of colic in adults due to insufficient high-quality evidence. Additionally, the mechanism by which charcoal might help is more relevant for cases of poisoning or overdose, where its ability to adsorb certain toxins is well established, rather than for functional gastrointestinal symptoms. In summary, while activated charcoal is traditionally used for colic, scientific support is minimal, and its use should be approached with caution, particularly given the risk of side effects such as constipation and interference with medication absorption.
