Endothelial cells surround the lumen of blood vessels and modulate many physiological processes, including vascular tone, blood fluidity, inflammation, immunity and neovascularization. Many pathological conditions, including hyperglycemia, may alter endothelial function through oxidative stress,
Oxygen toxicity and related free radical reactions are implicated in numerous pathophysiological conditions, like atherosclerosis, inflammation, gastric ulceration, neuronal degeneration, tumour promotion. The flowers of Matricaria chamomilla, Asteraceae, have been used therapeutically for
