The hibiscus is the name of the plant, the carcadé, the name of the floral cup of this plant, and the bissap, the name of the drink that is prepared with this chalice, and that we drink in Senegal, Egypt and much of sub-Saharan Africa.The HERBIER DE FRANCE hibiscus flowers are used as an infusion against hypertension. Incorporating hibiscus tea daily would reduce prehypertension and mild hypertension, as well as drugs prescribed for this purpose. That's what researchers at Boston's Tufts University said at the last annual meeting of the American Heart Association (AHA). The hibiscus is the plant, the carcadé the floral cup of this plant, and the bissap, the name of the drink that is prepared with this chalice, and that we drink fresh in Senegal, Egypt and in much of sub-Saharan Africa. It is a digestive plant, refreshing, diuretic and depurative. African medicine also gives it a hypotensive action, as well as an influence on the functioning of the uterus during childbirth. But these virtues are still little studied in Europe. Finally, hibiscus is increasingly used to replace chemical dyes in the food industry.
