"For every drug that benefits a patient, there is a natural substance that can achieve the same effect."

-Dr. Carl C. Pfeiffer-

Vegetable carbon is an anciently known substance that has been widely used for thousands of years as a healing remedy. It is especially well-known for its binding and cleansing properties and is commonly used to both treat and improve digestive distress.

Due to its special surface structure, activated vegetable carbon can adsorb unwanted substances that can harm or irritate the digestive system, promoting their rapid elimination before they can be reabsorbed into the body. Activated vegetable carbon is made from 100% plant-based sources.

The right amount of vegetable charcoal can help alleviate intestinal complaints in a sustainable, natural and safe way.
