Multiple Chemical Sensitivity (MCS) is caused by living in a toxic world. The chemicals that were synthesized after World War II (including, pesticides, synthetic fragrances, cleaning products, detergents, etc.) are mostly "petro-chemicals" (petroleum based) and are quite toxic to humans.

There have been virtually no studies done on the majority of these chemicals to see how they affect humans - the industry just placed the chemicals in the environment with the assumption that they are "safe, till proven toxic", instead of the other way around.

One of the biggest offenders is PERFUME and other scented products. Did you know that many of the ingredients in your perfume are the exact same ingredients found in GASOLINE?? I didn't either! The scary thing is that the perfume industry is NOT REGULATED at all - they can put any number of chemicals in fragrance without revealing what those chemicals are - or how they affect humans. We humans are all participating in a giant "lab experiment" against our knowledge and against our will, and it's making some of us VERY sick.

The products we use on our skin are absorbed directly into the bloodstream (the reason why nitroglycerine, nicotine, and hormone patches work). The chemicals we breathe (such as perfumes, formaldehyde, pesticides, etc.) all go straight to our brains and can cause low-level to severe damage - similar to how someone can snort cocaine or glue to get a "high". Start reading labels - check for petro-chemicals, formaldehyde, and fragrance, and avoid them as much as possible. A clue that an ingredient may be a petro-chemical is the "prop" prefix. A clue that an ingredient releases formaldehyde is "Quaternium". Be careful about products labeled "fragrance free" or "unscented". Don't trust them! Read the label and be sure they don't list "fragrance" or "masking fragrance". Don't put anything on your skin you'd be afraid to eat, because the end result is the same!
