Ginger essential oil, a must in Chinese medicine

Ginger is one of the most esteemed spices and drugs, and cultivated since ancient times in the Philippines. Its use is already mentioned in the oldest Chinese and Sanskrit writings . It was not lost on the ancient Greeks and Romans. The botanical name Zingiber comes from the Sanskrit word shringavera , which means “shaped like a deer antler”, referring to the shape of the young shoots emerging from its rhizome.

A little history

Ginger was already cultivated in India before the appearance of writing. Manuscripts dating back more than 3,500 years mention his name. But historians estimate its use dates back more than 5,000 years. In traditional Chinese medicine, ginger was a remedy associated with the treatment of diseases caused by an increase in Yin which is notably an element associated with cold as well as humidity.

In Europe, ginger was particularly popular with civilizations such as the Greeks as well as the Romans. This spice, which in the Middle Ages was considered magical and aphrodisiac, easily found its place on tables as prestigious as that of King Henry VIII .

Valnet (20th century) recommends, among other things, the essential oil for difficult digestion, diarrhea, the prevention of contagious diseases and impotence and, in local application, against rheumatic pain .

From Antiquity to the Middle Ages, it will therefore be considered a must. From the 9th century, ginger spread in Western Europe and thus settled there permanently. It became a very popular spice which, although imported in large quantities, remained relatively expensive, as it was intended for the wealthy of the time. On tables or in the medieval doctor’s office , ginger is indeed everywhere. He has such a reputation that it is even said that he could overcome the plague.

Hildegarde de Bingen takes an interest in ginger. In synergy with other plants, it treated constipation and sinusitis . From a culinary point of view, the Viandier de Taillevent (14th century) will give zinzibérine powder a place of honor, which means that it will remain current in the kitchen until the end of the 18th century, before being gradually abandoned in favor of pepper which thus dethrones the ginger of French tables.
