However, the leaf is used in A. ursinum and the bulb is used in A. sativum. A. ursinum also has higher quantities of many of the active substances than A. sativum does and upon digestion has less odor. In particular, A. ursinum has more of the water-soluble substances. As well, allicin has known side effects and is also highly unstable. We have briefly discussed adenosine and y-glutamyl peptides in this data sheet.
Flavonoids are substances in plants that often have health benefits.
Fructanes are significant because they are indigestible sugars known as oligosaccharides. Many companies market garlic products with a guaranteed allicin content. Allicin is important, but there is a wealth of research from Europe that shows that other constituents of garlic adenosine, y-glutamyl peptides, and others are equally important, if not more beneficial than allicin. Allicin can also cause side effects in some people, so products with high allicin content could be problematic. Usually ships the next business day.
