SOME DEFINITIONS

MULTIPLE CHEMICAL SENSITIVITY (MCS)
chronic, recurring disease with symptoms that resemble allergic reactions,
  but caused by the immune system of the sufferer being unable to cope with environmental chemicals;
it has become increasingly widespread as the range of chemicals in the environment has multiplied;
the name suggests that the sufferer is unusually 'sensitive'
whereas the 'sensitivity' is the result of damage by toxins

CHRONIC FATIGUE SYNDROME (CFS)
also known as Myalgic Encephalopathy or ME, it is a condition of excessive fatigue,
often with cognitive impairment and other varied symptoms;
it is classified by the World Health Organisation as a central nervous system disease of unknown etiology
that may last months or years, causing severe debility

HOMEOPATHY
from the Greek words homoios (similar) and pathos (suffering), this is a system of treatment that
involves the use of remedies without chemically active ingredients; in simple terms,
the theory of homeopathy holds that symptoms induced by a toxic substance in a healthy person
can be cured by a remedy prepared from that same substance;
it is the 'alternative therapy' that seems to offer the best means of treating MCS and CFS (see above)
