The Allimed® 100 capsule pack provides a month's supply of stabilised allicin What is allicin? When fresh garlic is cut or crushed, an amino acid, allicin, combines with an enzyme, allinase and a chemical reaction starts. The first compound that is formed is Allicin. Allicin, generated from fresh garlic, changes into a series of other sulphur compounds, known as thiosulphinates. Allicin is described as the 'mother' substance of garlic, which is responsible for the majority of its remarkable properties.
