the rhizome with many virtues
Ginger, whose scientific name isZingiber officinale, belongs to the family ofZinziberaceae and is native to India and tropical Asia.
Its peculiarity is the large fleshy rhizome from which the aerial stems of the plant depart.The stems are devoid of branches: the shorter ones (about 20 cm) are intended for the production of flowers while the longer ones (about 1.5 m) carry the leaves in charge of carrying out normal assimilation and photosynthesis activities.
The aromatic properties are given by its essential oil mainly made up of hydrocarbon sesquiterpenes, mainly zingiberene. The characteristic spiciness seems to be given by gingerol and zingerone and others that are found in small quantities in the fresh product but are particularly abundant in dry ginger.
The rhizome contains cellulose and numerous essential oils such as zingiberene, curcumene, camphor and compounds called gingerols and shogaoli, both responsible for the acrid aroma and its therapeutic properties. The former are found mainly in fresh ginger while the latter in dried ginger and their quantity depends on how the ginger was processed, therefore there is a substantial difference between fresh and dried ginger. In dried ginger (therefore in powder form) all its components are concentrated and also contains a high concentration of shogaol (during dehydration the gingerols are partly converted into shogaoli) which has properties similar to aspirin. more intense and therefore much more suitable for all those uses where you want to have its aroma.
The fresh root is more suitable for counteracting colds, to stimulate digestion, to dissolve phlegm, to eliminate nausea and vomiting (even motion sickness) .The powder is instead more indicated in cases of abdominal pain, diarrhea due to cold and to stop bleeding present in the urine.
