Advancis® Easylax Charcoal is a natural food supplement combining charcoal and fennel. Activated charcoal has traditionally been used to relieve flatulence after meals, since it has the ability to absorb intestinal gases, which contributes to reducing intestinal discomfort and the feeling of an expanding stomach. Fennel is also used traditionally for flatulence and stomach swelling. This plant is also used as a digestive stimulant.
