Rooibos potentially protects heart cells

According to the latest newsletter by the SA Rooibos Council, studies have shown that herbal plants and medicine may be an alternative way to protect the heart against disease.

Under the guidance of Dr. Gerald Maarman at Stellenbosch University, Pamela Sithelo investigated the ability of Rooibos to protect heart cells against the toxic effects of a molecule called angiotensin-II, (AnII), the same molecule involved in the development of high blood pressure. Heart cells were exposed to high levels of Ang-II to induce excessive growth and death, after which cell viability was measured.

In this first-of-its-kind study, it was shown that Rooibos prevents angiotensin-II (Ang-II) from causing excessive growth and death of heart cells.
