May protect against heart disease

Rosehip tea may enhance heart health due to its high antioxidant content. Several studies have found a link between vitamin C consumption and the risk of heart disease. A meta-analysis of 13 trials found that taking at least 500 mg of vitamin C per day was related to a considerable reduction in LDL (bad) cholesterol and blood triglycerides, two risk factors for heart disease. Furthermore, observational studies have connected a lack of vitamin C to an increased risk of dying from heart disease.

Flavonoids are abundant in rosehips. These antioxidants have been demonstrated to lower blood pressure and enhance blood flow to the heart in persons with high levels. A 6-week trial of 31 obese people revealed that those who ingested a drink containing 40 grams of rosehip powder per day had considerably lower blood pressure and LDL (bad) cholesterol levels than those who did not. However, the researchers speculated that the powder's high fiber content, which is absent in rosehip tea, may have contributed to the favorable benefits.
