I used activated charcoal around 15 years ago when I had very bad problems with flatulence. The problem with charcoal is that it will adsorb many different things, including vitamins and minerals your body needs. I suggest that you not use it. If you feel extremely toxic, I suggest that you try using a detox tea or licorice root tea. I have used the Triple Leaf brand and Yogi brand detox teas when I felt very toxic, and got relief from them. I use licorice tea on a regular basis. Ginger, garlic, cayenne, cinnamon, and turmeric may help. Sprinle plenty of these on your food(not at the same time, and when appropriate ). Licorice root is a great detoxifier, as is alfalfa, dandelion, echinacea, goldenseal, and milk thistle. If you haven't done a parasite cleanse in a long time, then consider doing one. Peppermint is also helpful. Dring plenty of water.
