The science of why Rooibos is good for you

Rooibos protects the heart and other vital organs
Drinking six cups of Rooibos per day helps to keep the heart healthy by preventing oxidative damage to the lipids (fat molecules) in your blood, enhancing glutathione (antioxidant of the body) levels and by improving the blood lipid profile. It also reduces total blood cholesterol levels, especially the level of “bad” LDL cholesterol (Phytomedicine, 2011).

Rooibos promotes heart health by inhibiting the activity of angiotensin-converting enzyme, or ACE. This enzyme is believed to be involved in the development of cardiovascular disease, and therefore ACE inhibitors are used to treat hypertension and heart disease (Public Health Nutrition, 2010).

Chrysoeriol, an antioxidant in Rooibos, can prevent and treat vascular disease by inhibiting the migration of smooth muscle cells inside the aorta, a key cause of the narrowing or hardening of the arteries that may lead to a heart attack (Journal of Pharmacological Science, 2009). Chrysoeriol is also an effective bronchodilator, and it helps to lower blood pressure and relieve spasms (European Journal of Nutrition, 2006).

Rooibos reduces stress
Rooibos lowers the production of cortisol – the “stress hormone” – in the body, thereby lowering the effect of the body’s stress response (Journal of Steroid Biochemistry and Molecular Biology, 2011).

Rooibos shows potential in treating diabetes
Aspalathin – the main antioxidant in Rooibos – helps muscle cells to use glucose more effectively and therefore to maintain normal blood sugar levels in mice with type 2 diabetes (Phytomedicine, 2009).

Rooibos protects against oxidative stress in diabetic rats, and it recommended to prevent and treat diabetic vascular complications (Physiology Research, 2006).

Rooibos protects the liver
Rooibos prevents the development of fatty liver disease – a potentially serious condition where fat accumulates in liver cells (Phytomedicine, 2011).

Rooibos helps damaged liver tissue to regenerate, and is recommended as an effective way to prevent and treat liver disease (General Physiology and Biophysics, 2008).
