This study included 40 overweight adults who were at high risk of heart disease. It suggested that consuming six cups of Rooibos Tea daily for six weeks decreased “bad” LDL cholesterol. There was also a boost in “good” HDL cholesterol.

Antioxidants quercetin and luteolin which are in Rooibos Tea was shown to kill cancer cells and prevent tumor growth.

Animal studies have shown that antioxidant aspalathin may have diabetic effects. This tea may help balance blood sugar levels and reduce insulin resistance.
