Pure Edenâ€™s â€œFood Gradeâ€ Activated Charcoal powder is 100% natural. It is made from coconut shells, contains no fillers or binders, and so is therefore twice as â€œadsorbentâ€ as tablets. Activated charcoal functions by means of a process known as adsorption, which is an electrical-type magnetic action, rather than absorption, which is more of a mechanical-type action. The activated charcoal is negatively charged and so attracts matter which is positively charged, such as toxins, chemicals and body wastes. Vitamins and nutrients are negatively charged, so are therefore not affected by activated charcoal. It can be taken internally by mixing it with water, added to your favourite dishes and drinks or used externally in the form of a poultice or in many DIY beauty remedies. Under no circumstances must you swallow the powder if it is not mixed. The most common side effects include: Black stools. The reason for this is due to the colour of the activated charcoal. If your stools are suddenly very black, it does not mean that there is anything wrong your stools. In fact, the black colour is completely harmless, and can hardly be called a side effect. Constipation is another potential side effect. The charcoal powder must be mixed with water when you take it. It's recommend that when you take Pure Eden Activated Charcoal internally, you follow it with a second glass of water. If you are at all inclined to constipation, keep your system well hydrated to prevent any problems.
