Its beneficial widespread effect on health is attributed to sulphur compounds and particularly to thiosulfinates. Odorless and stable, alliin is the most abundant sulfur compound in whole, unbruised Garlic. When the clove of garlic is cut or crushed, the enzyme alliinase is released from its compartment and transforms S-allyl-L-cysteine sulfoxide or alliin into diallyl thiosulfinate allicin, the characteristic compound of garlic flavor. This very unstable thiosulfinate is rapidly degraded to related organosulfur compounds. Allicin is often thought of as the "active ingredient" in Garlic, and has been the subject of numerous scientific studies, but its a fairly unstable compound that likes to react with itself.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
