Chromium and zinc in a series of plants used in Portugal in the herbal treatment
2001
Osorio e Castro, V.R.
Chromium and zinc are essential micronutrients for humans. Chromium's main action is thought to be the regulation of blood sugar, because chromium deficinecy is related with diabetic-like (type 2) symptoms, and chromium supplementation is associated with increased glucose tolerance and insulin sensitivity. Zinc supplementation also alleviates hyperglycaemia of the same type of diabetic patients contributing to improved insulin activity. Some Portuguese plants are commonly used as teas, alcoholic extracts or as powders by diabetic people and as medicines. Although their active principle is not yet known, the importance of their chromium and zinc content in the claimed therapeutic properties should not be disregarded.
