Rosehip Safety in Humans: Toxicity, Side Effects, and Food Safety
Toxicological Safety and Genotoxicity of Rosehip Extracts
Studies evaluating the safety of rosehip extracts, including standardized polyphenol-rich preparations, have found no evidence of genotoxicity or significant toxicity. In animal studies, rosehip extract did not cause gene mutations, chromosomal aberrations, or micronucleus formation, and no adverse effects were observed even at high doses (up to 1000 mg/kg) over a 90-day period. These findings suggest a high margin of safety for rosehip extract consumption in terms of toxicity and genetic safety .
Clinical Safety in Human Use
Systematic reviews of clinical trials investigating rosehip supplementation for cardiovascular and metabolic health have generally reported a favorable safety profile. While the efficacy of rosehip for lowering cholesterol and blood glucose is mixed, no serious adverse effects have been consistently reported in these studies. However, the reviews emphasize the need for more research to determine optimal dosages and long-term safety in diverse populations .
Rare Adverse Events: Case Report of Kidney Injury
Despite the overall positive safety profile, there are rare reports of adverse effects associated with excessive rosehip consumption. One case described a woman who developed acute interstitial nephritis (AIN), a form of kidney inflammation, after consuming large amounts of rosehip tea over two months. The report suggests that excessive intake may trigger inflammatory responses in susceptible individuals, highlighting the importance of moderation and medical supervision, especially for those with pre-existing health conditions .
Food Safety and Microbial Contamination
Rosehips, like other wild berries, can carry diverse microbial communities on their surface, including both beneficial and potentially pathogenic bacteria and fungi. While the presence of these microbes is typical for unprocessed berries, proper handling and processing are important to minimize any food safety risks. The study underscores the need for good hygiene practices when consuming or preparing rosehips, especially in raw or minimally processed forms .
Safety in Osteoarthritis and General Use
Meta-analyses of rosehip powder for osteoarthritis pain relief have not reported significant safety concerns, though the data is limited and longer-term, larger-scale studies are needed to fully confirm its safety profile. The available evidence suggests that rosehip is generally well-tolerated as a nutraceutical .
Conclusion
Current research indicates that rosehip extracts and supplements are generally safe for human consumption, with no evidence of genotoxicity or significant toxicity at typical doses. Clinical studies and meta-analyses support a favorable safety profile, though rare adverse events such as kidney inflammation have been reported with excessive intake. As with any supplement, moderation and attention to individual health status are advised. Proper handling is also important to ensure food safety when consuming unprocessed rosehips. Further research is needed to confirm long-term safety and optimal usage guidelines in diverse populations 1235+1 MORE.
