Acute Adverse Effects From Fluoride Intake:
Double-Blind Experiments & Case Histories
- The Netherlands
Dr. Hans Moolenburgh organized a group of practitioners and
researchers to study the effects of fluoridation on health.
After unblinded tests on skeptical General Practitioners which
showed negative health effects (similar to low-grade poisoning),
he conducted a double-blind experiment:
"To obtain unassailable proof that nothing but fluoride in the
wayer was responsible and that the ill effects were not imaginary,
Dr. Moolenburgh's group turned to a double blind procedure. A
cooperating pharmacist prepared eight numbered bottles of drinking
water, some with fluoride, some without. Only the pharmacist knew
which ones contained fluoride. The numbers, placed in a sealed
envelope, were sent to the group's attorney. Patients who had
recovered from side effects after changing to non-fluoridated water
drank daily, one l iter of water from one of the bottles given to
them. If symptoms occurred, the number of the bottle was sent to the
attorney in a sealed envelope. Only after all the envelopes were
received were they opened in the presence of witnesses to avoid any
possibility of bias. The positive results of these double-blind
tests were published in "Fluoride" (7:146-152, July, 1974) in an
article by Dr. G.W. Grimbergen, one of the members of the group
organized by Dr. Moolenburgh.
"In addition to the original 12 physicians practicing in Haarlem and
some of its surrounding fluoridated areas, various individuals with
training in biology, chemistry, and neurology also participated in
the above study. The main symptoms exhibited by the patients were
gastro-intestinal, stomatitis, joint pains, polydipsia, headaches,
visual disturbances, muscular weakness, and extreme tiredness. A
definate relationship between the symptoms and fluoride in water was

Needless to say, The Netherlands banned toxic fluoride compounds
from their water supply.
- United States
Dr. George L. Waldbott noted a women experiencing muscular weakness
and headaches from drinking fluoridated water. After four weeks of
avoidance of fluoride-containing products, she had a dramatic recovery.
Dr. Waldbott published this case history in the International Achives of
Allergy and Applied Immunology, Volume 7, pages 70-74, 1955.
After that time, Dr. Waldbott founded the International Society for
Fluoride Research. He published over 80 clinical reports and conducted
double-blind studies which proved that water fluoridation causes adverse
effects such as muscular weakness, thyroid problems, symptoms mimicing
osteoarthritis, gastrointestinal disturbances, and a myriad of other
health problems. He published these results in respected medical
journals. He also coathured a book about his experiences with Professors
A.W. Burgstahler and H.L. McKinney of the University of Kansas entitled
"Fluoridation: The Great Dilemma" (Coronado Press, c1978).
"In or own practice, we have run down cases of hives, behavior problems,
and several patients which others had labeled neurotics to be due to
fluoride intoxication." Allergist Dr. Jonathan Forman from "Fluoride: The
Aging Factor" by Dr. John Yiamouyiannis.
There are many others who have noticed cases of serious adverse effects
from fluoridation, many which cleared up on removal of fluoride products
and predictably returned upon the reintroduction of fluoride products.
- Sample Case History
My name is Deloss E. Winkler. I was born February 4, 1914, on a farm
five miles north of Atchison, Kansas. My early schooling was in a
one-room brick school house. I graduated from Atchison High School in
1932 in a class of 130 students. The next two years I was enrolled as a
student at St. Benedicts College in Atchison, Kansas, and then went to
the University of Kansas, Lawrence, Lansas, for my junior and senior
years, graduating in 1936 with a major in organic chemistry.
I taught high school classes in Potter, Kansas, for one year, and that
summer worked for the American Can Company in Maywood, Illinois, west of
Chicago as a chemist in the Coatings Department.
In the fall I returned to the University of Kansas to work toward an
advanced degree. To help with expenses I was able to obtain a position as
an Assistant Instructor in the Chemistry Department, which I held for two
years, and then was given a two-year State Industrial Fellowship. I
received a Masters Degree in 1939 and a Ph.D. in 1941 with a major in
organic chemistry and a minor in metallurgy.
In June of 1941 I began working for Shell Development Company in
Emeryville, California, in the San Francisco Bay Area. My work was
considered vital to the war effort so I was never inducted into the armed
forces. I started at Shell as an organic chemist, but gradually
gravitated toward plastics, rubber, and polymers in general.
I have thirty-eight patents and fourteen publications in scientific journals.
In 1970 I retired from Shell when Shell decided to move its laboratories
from Emeryville to Houston, Texas, but soon accepted a position as a
polymer chemist with Beckman Instruments in Palo Alto, California.
When I started work in Palo Alto, I suffered a series of sick spells
which might be described as "flu-like", in which I experienced chronic
fatigue, muscular weakness, and muscular aches. The fatigue and muscle
weakness was so overwhelming that I was unable to perform any normal task
and was forced to stay in bed for a week each time, until I gained the
strength to return to work. This occurred about once a month, so during
my first eight months with Beckman Instruments I was absent from work
twenty-five percent of the time and *never* felt up to par. Doctors in
Palo Alto and at Kaiser Permanente in Oakland were unable to help me, and
I was beginning to despair of ever being well again. Was I going to
When my wife, who had studied fluoridation for a number of years, learned
that Palo Alto water was artificiall fluoridated, she suggested that I
carry unfluoridated water from our home in Orinda to Palo Alto for
drinking. The result was truly miraculous and I was able to lead a normal
Consultation with The Physicians Desk Reference revealed that my problem
was fluoride poisoning. Now, because of my sensitivity to fluoride, when
I travel I must buy distilled water whenever I am in a fluoridated area;
and at home, now that East Bay Municipal Utility District water is
fluoridated (since 1976), we distill all our drinking and cooking water.
Fifteen years ago, to test our diagnosis, I took part in a double blind
test in which I was given a one week supply of water at a time, sometimes
fluoridated with 1 ppm fluoride using hydrofluosilici acid, sometimes
not. (Hydrofluosilicic acid is the compound used by East Bay Municipal
Utility District to fluoridate.) Neither the doctor nor I knew which
water was fluoridated as a third person determined this. My body
accurately identified the water containing the fluoride.
In my opinion, a public water district should not use a procedure which
has the known possibility of harming any of the people using it. In the
case of fluoride, not fluoridating the public water supply will not
cancel anyone's opportunity to u se fluorides from many other sources if
they so choose, but it will respect the right of the individual who wants
to avoid fluoride.
