For certain people the entire world has become an allergen. No one really knows the ultimate effect of the 4 million chemicals we've created since 1915.
Food allergies are just one part of a large picture.
The biggest offender may be the seemingly harmless carpet under your feet. Most of us are exposed to over 1,200 potentially toxic chemicals in our homes. 700 in our drinking water alone. It's up to you to seek out remedies since it's for sure big business who produces these items that give off gas and other toxins aren't going to give us the remedies - which are simply to quit manufacturing these things and for us to stop buying them and buy only natural products. Ultimately, we must heal the earth before we can truly heal ourselves.
