More than 2000 scientific papers citing allicin are available on 'Athens', the university and scientific community database or you can look in Pub Med.
Allicin has been tested in vitro (in the lab) and proved effective against a wide spectrum of otherwise resilient threats. In vivo (in life), allicin tests very positively. It has been used recently, for example, in trials led by Dr R Cutler (Queen Mary University, London). The papers are available on a Google Scholar search (Dr R R Cutler, allicin).
