Zinc, Covid, Hypertenion

Zink und Blutdruck

A few years ago we described in a blog on www.malariaword.org the role zinc may have in diarrhea and tropical diseases. Zn2+ deficiency is a common comorbidity of many chronic diseases. In a recent weblog we describe the deleterious effect of zinc deficiency in elderly people on the development of pneumonia. Zinc deficiency has a detrimental effect on blood pressure and hypertension is one of the major causes of mortality in Covid infections. A systematic review and meta-analysis of randomized clinical trials on the effects of zinc supplementation on blood pressure in adults was made in Iran. A significant reduction in systolic blood pressure following zinc supplementation was found. However, zinc supplementation had no significant effect on diastolic blood pressure.

An analysis of a dozen of medicinal herbs in Romania showed that Artemisia absinthium is top ranking in Zn content.
