The value of Wachters' Sea Vegetation

Value of Sea Vegetation
Following are quotations from research concerning the potential
production and activity of antibiotic, antibacterial, antimicrobial, antifungal,
and antiviral substances in seaweeds. These have been taken from a number
of reports, quotations and bibliographies of which some are given here. Space
does not permit presentation of these reports in their totality.
Time here does not permit us to go on and on with quotations
and many studies have been prepared and completed on the various antibacterial,
antimicrobial, antibiotic and antiviral properties of sea plants. The files
and research papers contained in the Josephine E. Tilden Memorial Museum and
Library contain numerous reports on testing performed and completed in these
areas. It should be noted here that these compounds are found in the sea plants
used in The Wachters' Blend of Marine Algae.
- "If we take inventory of the more than 40,000
species of land plants of which at least 10,000 have been chemically and
pharmacologically screened in one way or another, our record of success
has been somewhat impressive. Should not the carbohydrates, amino acids,
biotoxins, enzymes, steroids, and other chemical products of the sea have
similar therapeutic uses in pharmacy and medicine? The gains from the years
of studies with land organisms from chemical isolation of pharmacologistical
evaluation and more sophisticated equipment than that which is now available
in the modern laboratory for these studies are surely assets in our turn
to the resources of the sea. We must now organize the search more effectively
for the therapeutic agents which the oceans will surely yield." Sources

Rhode Island. Excerpts from Drugs From the Sea.
- "In the protistans, which include the red, brown,
and green algae, the diatoms and dianoflagellets, there are many members
possessing a wide range of pharmacological activity. Generally the red,
brown and green algae contain useful phycocolloids and vitamins and some
contain antibiotic principals."
- "Digena simplex has yielded kainic acid, a valuable
Vermifuge or anthelmintic against the parasitic round worm, Acaras lumbircoides,
the whit worm, Trichuris trichura and tape worm, Taipia supp."
- "Another seaweed Laminaria coloustoni species
yield the polysaccharide, laminarin, which consists essentially of B-B-Glucose
residues. The highly sulfated derivities of Laminarin have anticoagulant
properties comparable to heperin."
- "One unique use of sodium alginate is seen in
its availability to inhibit uptake of radiostrontium for the human gastrointestinal
tract. In human test, 0.36 microcurides of Sr 85 was administered orally
20 minutes after an oral administration of ten grams of sodium alginate.
Twenty-six days later, 0.48 microcurides of Sr 85 was given orally. In both
phases of the experiment, samples of excreta and blood were collected in
the body retention of Sr 85 as measured by means of Windscale whole body
counter. Based on blood plasma, urine and body retention measurements, sodium
alginate reduced the uptake of radiostrontium from the gastrointestinal
tract by a factor of about 9. This discovery is of great importance and
Sr 90 is probably the most hazardous of all long lived fission products
occurring in nuclear weapon fallout. The use of sodium alginate appears
to be able to remove this contaminant from the body without seriously effecting
the availability of calcium, sodium or potassium to the body." Hesp,

- "Kamimoto showed that seaweed extracts inhibit
the growth of pathogenic bacteria. In studies of the antibacterial activity
of other extracts obtained from British seaweed Chester and Stott found
Halidrys siliquosa, Pelvetia canaliculata, Laminaria digitata and Polysiphonia
fastigiata especially noteworthy."
- "There has been a considerable interest in characterising
the antimicrobial substances responsible for the reported activities of
diverse marine seaweeds through either extracts of the brown Sargassum netans,
and Chondria littoralis were studied with alumina and paper chromatography
by Martinex Nadal and Co-workers."
- "Volatile organic acids called the "Sargano
small complex" were prepared and demonstrated to have broad-spectrum
antibacterial and antifungal activity as well as cytotoxic activity against
K B tumor cells. " Quoted from Antimicrobial Substances from the Sea,

- "In bone grafts already sulfated polysacchardoids
from seaweeds have been used in films which are placed between the bones
to be grafted so that the growth of connective tissue will be stimulated
in the graft will start growing together in a more rapid pace than normal."
- "Seaweed sulfated polysaccharides increase the
growth of connective tissue in collagen and it has been shown that the sulfated
polysaccharides of the body must be involved in connective tissue growth
in some manner. Experiments have shown that the sulfated polysaccharides
may be involved in arthritis and are active in promoting and helping the
healing process of the body (Highton)."
- "In experimental work it was noticed that carragenan
(extract of red algae) among other sulfated polysacchardois protected guinea
pigs from ulcers produced by injection of histamine."
- "It was also expounded that carragenan reacted
with the mucoid lining of the stomach and gave a protective layer through
which pepsin and acid has difficulty in passing." From the use of seaweed
extracts in the fields of food and medicine. Sydney D. Upham, Rockland,
