Rose Hip Inhibits Chemotaxis And Chemiluminescence Of Human Peripheral Blood Neutrophils In Vitro And Reduces Certain Inflammatory Parameters In Vivo
| Effect |
None |
| Trial Design |
Cohort |
| Trial Length |
1-6 months |
| Number of Subjects |
13 |
| Gender |
Both Genders |
| Age Range |
30-44, 45-64 |
| Body Types |
Average |
Notes for this study:
Rose hip supplementation at 10g (low dose) or 45g (high dose) in otherwise healthy persons appeared to reduce C-reactive protein by 20-40% at the higher dose and also reduced creatinine concentrations. There was no observed effect on other parameters measured aside from chemotaxis, which was reduced by over 50% in 12/13 persons.
Effects Of Rose Hip Intake On Risk Markers Of Type 2 Diabetes And Cardiovascular Disease: A Randomized, Double-blind, Cross-over Investigation In Obese Persons
| Effect |
Decrease |
| Trial Design |
Double blind |
| Trial Length |
1-6 months |
| Number of Subjects |
31 |
| Gender |
Both Genders |
| Age Range |
30-44, 45-64 |
| Body Types |
Obese |
Notes for this study:
Supplemenation of a high dose (40g) of rosehip powder via a beverage daily for six weeks in obese persons without diabetes was able to reduce blood pressure mildly (3.7%) with minor reductions in total cholesterol due to the LDL component, although no other measured biomarker was changed.
Daily Intake Of Rosehip Extract Decreases Abdominal Visceral Fat In Preobese Subjects: A Randomized, Double-blind, Placebo-controlled Clinical Trial
| Effect |
None |
| Values |
207.8 vs. 213.1 placebo vs. rose hip. Not significant. |
| Trial Design |
Randomized trial |
| Trial Length |
2-4 Weeks |
| Number of Subjects |
32 |
| Gender |
Both Genders |
| Age Range |
30-44, 45-64 |
| Body Types |
Overweight |
Notes for this study:
32 subjects with a BMI between 25 and 30 were enrolled in this single-blinded12 week study that compared 100 mg rose hip extract to placebo. At the end of 12 weeks, bodyweight and abdominal fat area was significantly lower in the rose hip group compared to placebo, with no changes in caloric intake as measured by food diaries. No changes in blood chemistry or blood pressure was seen.
Funding issues for this study:
Three authors not involved in the data analysis were employees of the company which manufactured the rose hip extract used in this study.
Rose Hip Herbal Remedy In Patients With Rheumatoid Arthritis - A Randomised Controlled Trial
| Effect |
None |
| Trial Design |
Double blind |
| Trial Length |
1-6 months |
| Number of Subjects |
89 |
| Gender |
Both Genders |
| Age Range |
45-64, 65+ |
| Body Types |
Average |
Notes for this study:
Rose hip supplementation at 5g for six months in persons with rheumatoid arthritis appeared to show benefits on a health assessment questionnaire (HAQ) at six months yet not three. While there was a trend to improve overall symptoms of rheumatism by clinician rating and DAS-28 rating, the rating scale selectively looking at pain in joints (HAQ patient pain scale) failed to find any benefit. C-reactive protein trended to decrease but failed to reach statistical significance.
Degree of improvement on the global symptoms reached 30% (physician rating) and 19% (DAF-28) relative to baseline values.
