I think that as also some scientist suggest that liver dysfunction is the main cause of many diseases such as renal disease , atherosclerosis even some types of diabetes and failure in detoxification function of the liver may lead to accumulation of toxin and by aging of persons this waste will affect the normal function of the blood vessel and may lead to blood hypertension , then the healthy liver means no risk blood pressure , so I will ask you , how we are able to maintain healthy and powerful liver from 20 year old up to 90 years old ?
