Regulatory bodies of all serious complementary
therapies, including acupuncture and Shiatsu, prohibit their members
from claiming to be able to "cure" diseases. This is in order not to
make claims one may not be able to fulfil. The human body is a very
complex mechanism, in which many factors come into play, thus the
manner in which a particular disease develops can be different for
different individuals. It does happen sometimes that symptoms disappear
without a trace; also often that they are alleviated, but come back
from time to time. As a rule of thumb, the more chronic the condition,
the longer it will take to make the difference.
