Tin is found in the tissues
and has many chemical and physical properties similar to that of carbon, silica, germanium
and lead. Tin is found primarily in the lungs and intestines. For a long time the human
biological applications were not known.
In 1970, a man by the name of Schwarz was able to demonstrate,
"that tin produced an acceleration of growth in rats and further met the standards
for an essential trace element," as quoted from Rare Earths by Dr. Joel
Wallach. While conducting the research for this informational sheet there was very little
documentation of studies or any other biochemical notations about tin to be found.
It is known, however, that tin has been implicated in hair loss and
hearing loss. A recent study conducted by Yokoi et al indicates that when there exists a
tin deficiency in rats, they exhibit poor growth, decreased food efficiency, a depressed
response to sound, and changes in mineral concentrations in various organs. These results
do need further study to confirm these conclusive statements.
Below is a list of those conditions believed to result from a Tin
deficiency:
