Eden Healthfoods Activated Charcoal is an ultra-fine, medicinal grade powder, derived from coconut shell fibre. It provides a neutral pH, and has been purified and steam activated (unlike chemical activation). This increases its adsorption (bonding) capacity by making it 3-5 times more porous.
Unlike food grade charcoal powder, medicinal grade charcoal has undergone a purification process which further enhances its drawing capacity, more than steam activation alone.
