Effects of orally administered activated charcoal on intestinal gas.

Hall RG Jr, Thompson H, Strother A.

The effectiveness of activated charcoal in treating intestinal gas, following a gas producing meal, was compared with a placebo. Both the number of flatus events and breath hydrogen levels were measured. These experiments showed that orally administered activated charcoal was effective in preventing the large increase in the number of flatus events and increased breath hydrogen concentrations that normally occur following a gas-producing meal.
