Rosehips are the fruit of the rose plant which have been used medicinally for thousands of years in the battle against the modern epidemic obesity. Animal studies have shown that its extract inhibits weight gain, decreasing visceral fat, but was not sure if this can be effective among people. Thus, Japanese researches decided to find this out and conducted a 12-week, double-blind, randomized, placebo-controlled study of 32 people who had a body mass index above 25 and less than 30. They were considered overweight but not obese according to BMI. Each day they received a chewable tablet that contained a placebo or 100 mg of rosehip extract. During this study, the participant didn’t have any diet changes. Abdominal body fat (subcutaneous and visceral fat), body fat percentage, weight, and body mass index at various times during the trial have been measured. After 12 weeks the group which consumed rosehip extract had a significant decrease on the abdominal, body, and visceral fat, abdominal weight, and BMI compared to the placebo group, so the scientists came to a conclusion that this extract may be very useful as a supplement to reduce the abdominal fat in a safe way in pre-obese people. It is expected to reduce the risk of cardiovascular disease.

How does this extract work?

The extract which has been used in the study contained 0.1% tiliroside which is a major rosehip seed constituent. It accelerates fat metabolism, improving glucose clearance. It inhibits fat accumulation in tissue stimulating the fat burning process at the same time. This substance has also anti-inflammatory, anti-oxidant, and anti-bacterial properties. Further, rosehips are high in vitamin C (100 gr. of dried rosehip contain 1,700-2,000 mg of vitamin C). It boosts the immune system and prevents or treats colds. Then, they are rich in vitamin A, E, and B complex, calcium, iron, manganese, and selenium.

They can be used in jams, jellies, juices, syrups, and teas. But they can be available in supplement form and they may relieve: chronic lower back pain, rheumatoid arthritis, and osteoarthritis of the knee and hip.
