  Relief, A Natural Aspirin alternative, NutriBiotic
NutriBiotic Relief tablets contain salicin, which the body converts to salicylic acid and has the same effect on the body as aspirin without any of the harsh side effects.
The body converts salicin to salicylic acid, which has the same effect on the body as aspirin (acetylsalicylic acid) without the harmful side effects.
Salicin must be metabolized in the body before it becomes salicylic acid, therefore it will take longer to begin acting than aspirin, but the effect may last longer.

 SALICINUM. - THE ENCYCLOPEDIA OF PURE MATERIA MEDICA By TIMOTHY F. ALLEN, A.M., M.D.
Next day, the first on which Salicin was given, the temperature fell after the dose of 30 grains, 0.4° in one hour and a half, and remained depressed for about three hours, and then rose to its original height in spite of the continuance of the medicine.
The only effect, therefore, of the Salicin, was very slight and temporary depression of the temperature, not maintained by the continuance of the medicine, and the diurnal fall was not quite so great as on the two previous days, though within the limits of the variation of health.
Next day, when 3 drachms of Salicin, in divided doses, was given, the temperature was not even temporarily depressed; in fact; it rose 0.6° between 9 A.M. and 1 P.M., and then slowly fell 0.3° till 3.30 P.M. The evening fall began between 7 and 8 P.M., and the diurnal variation amounted to 1.5°.

 FEBS Abstract
Cellobiose, arbutin, salicin, and esculin are sugars belonging to a group of saccharides called (beta)-glucosides consisting of two units joined by a (beta)-glycosidic bond.
All these observations indicate that for salicin, arbutin, and esculin assimilation at least two different systems are used.
Salicin, arbutin, and esculin are transported via PEP-PTS, which undergoes regulation by CcpA and BglR control proteins, whereas cellobiose is assimilated through cellobiose-specific PEP-PTS regulated by CcpA, only.

 Plant toxins: a double-edged sword - toxins may work against the plant itself Science News - Find Articles   (Site not responding. Last check: 2007-11-01)
Salicin, a toxin produced by willows, so improves one kind of willow-eating beetle's survival that the willows that produce the most salicin end up suffering the most beetle-inflicted leaf damage, report researchers at the University of California at Irvine in the Aug. 16 SCIENCE.
By measuring both leaf damage and salicin content in individual willow shrubs, the researchers discovered that the more salicin a willow produced, the more heavily it was damaged.
They also suggest that, more generally, repeated exploitation of secondary compounds by plant-eating insects may account for the great diversity of secondary chemicals that plants produce: That is, every time an insect herbivore adapts to a plant's toxins, the plant is forced to produce a new one.

In 1838, the Italian chemist, Raffaele Piria, succeeded in splitting salicin to obtain salicylic acid, which was derived from methyl salicylate, isolated from oil of wintergreen.
In addition to its antipyretic properties, salicylic acid was also found to have anti-inflammatory effects relieving stiffness and pain in rheumatic fever patients, as well as being used as a pharmaceutical and food preservative.
Due to later reports that salicin was less efficacious than sodium salicylate and often produced skin rashes, salicin last appeared in the British Pharmaceutical Codex (BPC) in 1954.

White willow, like other willows, is a natural source of salicin, a precursor of modern aspirin, and indeed it has been used for centuries worldwide as a pain reliever.
Although all parts of the plant contain some salicin, the best source is the mature bark, either fresh or dried.
Like other salicin-producing plants, white willow also reduces fever and inflammation, probably by suppressing the action of prostaglandins (hormone-like substances), which are produced by the body in response to injuries.

In the 19th century the West discovered the active constituent in willow bark to be salicin, a natural chemical which the body first converts into saligenin and then into salicylic acid.
As well, there have been various scientific studies done on white willow bark indicating that salicin is converted to salicylates in the blood.
Their comparative blood level studies show that salicin (the precursor to salicylic acid found in willow bark) may reach peak levels more slowly, but it stays active much longer than products containing only salicylic acid such as aspirin.

The active ingredient in white willow is salicin, which the body converts into salicylic acid.
Capsules, tablets, and other supplement forms that contain a standardized amount of the active ingredient, salicin, are more reliable than teas made from white willow bark because the unrefined bark contains only small amounts of salicin.
Although white willow bark is unlikely to cause the rare but potentially fatal condition called Reye's syndrome in such cases--it is metabolized differently than aspirin--the similarity to aspirin is close enough to warrant caution.
