Rooibos tea teva ember moc3/1/2024 Its beautiful, red color has dubbed rooibos as the “African red tea” or “red bush tea.” Once the plants are harvested and dried, the herbal infusion will create a reddish-brown cup. Rooibos is technically an infusion because the plucked tea is in needle form instead of the typical leaf shape. The rooibos plant has long slender leaves with yellow flowers and is usually harvested in the summer. Grown in Cederberg’s mountainous region (three hours north of Cape Town), rooibos comes from the Aspalathus linearis plant, which is part of the legume plant family. The fact it is enjoyed globally but only grown locally is perhaps what makes this tea so unique. Despite their effort to harvest beyond their borders, South Africa continues to be the only rooibos producer in the world. It may also lower LDL (bad) cholesterol and raise HDL (good) cholesterol in those at risk of heart disease.Rooibos (pronounced “roy-boss”) is an herb native to South Africa. Rooibos tea may benefit heart health by positively affecting blood pressure. Having healthy cholesterol levels is linked with a lower risk of various heart conditions, including heart attacks and stroke ( 21, 22). In a 2011 study in 40 adults with overweight at high risk of heart disease, drinking 6 cups (1,420 mL) of rooibos tea daily for 6 weeks decreased LDL (bad) cholesterol while boosting HDL (good) cholesterol ( 20). There is more promising evidence that the tea can improve cholesterol levels. However, this did not translate to any changes in blood pressure ( 18). In a study in 17 people, drinking rooibos tea inhibited ACE activity 30–60 minutes after ingestion. Rooibos tea could support heart health through several mechanisms.įirst, drinking rooibos tea may have beneficial effects on blood pressure by inhibiting angiotensin-converting enzyme (ACE), according to one older study ( 18).ĪCE indirectly increases blood pressure by causing your blood vessels to contract ( 19). However, these antioxidants may be unstable or inefficiently absorbed by your body. Rooibos tea is full of health-promoting antioxidants. Therefore, more high quality, recent research in humans is needed. This is possibly because the antioxidants in rooibos are short-lived or inefficiently absorbed by your body ( 16, 17). On the other hand, an older study in 12 healthy men determined that rooibos tea had no significant effects on blood antioxidant levels compared to a placebo ( 16). This uptick lasted for 5 hours after the participants drank 17 ounces, or 500 milliliters (mL), of tea, which was made with 750 milligrams of rooibos leaves ( 15). In one small 2010 study, blood levels of antioxidants increased by 6.6% when participants drank red rooibos and 2.9% when they drank the green variety ( 15). However, any increase documented has been small and doesn’t last long. There is some evidence that rooibos tea can increase antioxidant levels in your body. Over the long term, antioxidants may also reduce your risk of certain chronic conditions, such as heart disease and cancer ( 13, 14). Rooibos is associated with health benefits due to its high levels of health-promoting antioxidants, which include aspalathin and quercetin ( 10, 11).Īntioxidants may help protect cells from damage by free radicals ( 12).
