Multiple Chemical Sensitivity (MCS)


What is MCS?

 Sufferers are affected by different triggers and their health improves when the triggers are removed. The quality of health deteriorates for people with MCS when exposed to chemicals or fragrances, more than it appears to in the general public. Multiple body systems are affected and differ from individual to individual.  Symptoms range from annoying to debilitating.



  • A person may have had an acute toxic experience that weakened their immune system

  • A person may have had smaller exposures over a long term (community buildings, outdoor pollution, workplace, home)

In recent years, some people affected by MCS and other limbic system impairments have found good results with neuroplastic programs to rewire the brain.  (see resources)

 For sufferers with Multiple Chemical Sensitivity, the avoidance of pollutants/toxicants is key to wellness.
