Key Constituents
The hip is exceptionally rich in vitamin C and carotenoids, underpinning its traditional tonic use. Quantified in commercial dried fruit at beta-carotene 7.25 mg/100 g and lycopene 2.34 mg/100 g fresh weight.
A specific galactolipid fraction studied as the likely active anti-inflammatory constituent in osteoarthritis trials of standardised rosehip powder.
Contribute to antioxidant activity. Leaves carry a higher total phenolic, flavonoid and phenolic-acid content than the hips, and leaf infusions were the only preparation to show antibacterial activity in vitro.
Cold-pressed rose hip seed oil is high in linolenic acid, with phytosterols up to 6485 mg/kg, tocopherols up to 1125 mg/kg and carotenoids up to 108 mg/kg; p-coumaric acid methyl ester predominates among its phenolics.
The dominant bioactive class, driving much of the antioxidant and anti-inflammatory activity.
Studied for immunomodulatory, hepatoprotective and gut-microbiota-modulating effects.
Concentrated in the hips, underpinning their traditional food-tonic use.
Isolated from the root and studied for antioxidant/neuroprotective activity.
Pharmacological Actions
In vitro, the lipophilic (n-hexane and dichloromethane) rose hip extracts inhibited COX-1, COX-2 and 5-LOX-mediated leukotriene B4 formation; the aqueous and methanol extracts were inactive.
Traditional & Indicated Uses
Two placebo-controlled crossover RCTs of standardised rosehip powder (5 g/day) report reduced WOMAC pain and reduced rescue-medication use in knee/hip osteoarthritis, consistent with the existing meta-analysis.
inferred from anticancer action
Animal evidence only. In high-fat-diet/streptozotocin diabetic rats, R. canina ethanol extract (250 mg/kg) improved recall and long-term memory and reduced hippocampal insulin resistance, amyloid-beta and acetylcholinesterase activity. No human data; the effect is reported in a diabetes model, not in healthy or cognitively impaired people.
inferred from anti-inflammatory action
inferred from anti-inflammatory action
One triple-blind placebo-controlled RCT (n=400) found that 500 mg R. canina fruit capsules twice daily for 20 days after caesarean section reduced the incidence of urinary tract infection. The incidence of cystitis specifically did not differ significantly between groups. Prevention in a post-surgical population; not evidence for treating an established UTI.

Safety, Cautions & Contraindications
Rosa canina (dog rose) hips are generally recognized as safe (GRAS) for consumption, widely used in teas, jams, and supplements. They are highly nutritious but may cause minor digestive upset (nausea, diarrhea) in some users. The small, irritating hairs around the seeds should be removed before consumption.
Duke (2002) rates dog rose hips as +++ with clinical evidence (score 2) for astringent activity and experimental support for antioxidant and diuretic effects. Dog rose hips are exceptionally rich in vitamin C and bioflavonoids. They are traditionally used for cold and influenza prevention, urinary tract health, and mild diarrhea. Duke notes the diuretic (score 1) and lipoxygenase-inhibitory activities as experimentally documented. The fruit is considered food-grade safe (Duke, 2002).
Generally safe as a food plant. Rose hips should be used after removing the achenes (seeds and inner hairs), which can cause irritation. Allergic reactions are rare. No significant drug interactions documented.

Botanical Description
Scrambling, thorny deciduous shrub (Rosaceae), 1-5 m, with arching, prickly stems bearing hooked thorns. Leaves are pinnate with 5-7 oval, toothed leaflets. Pale pink to white, five-petalled flowers are followed by bright red-orange, egg-shaped hips (the fleshy hip is an accessory fruit; the true fruits are small hairy achenes inside it) that ripen in autumn and often persist into winter.[2]
Dense, thicket-forming deciduous shrub (Rosaceae), 1-1.5 m tall (occasionally to 2 m), with stems densely covered in numerous straight, bristly thorns. Leaves are pinnate with 5-9 deeply veined, glossy, leathery leaflets. Large, fragrant, deep pink to white, five-petalled flowers are followed by large, tomato-red, flattened-globose hips.[2]
Habitat
Native throughout Europe, north-west Africa and western Asia, common in hedgerows, woodland edges, scrub and roadside verges on a wide range of soils.[2]
Native to coastal eastern Asia (Japan, Korea, China, far-eastern Russia), typically growing on sand dunes and coastal scrub. Widely planted and naturalised as an ornamental and hedging shrub, notably tolerant of salt spray, wind and poor sandy soils, in temperate coastal regions worldwide.[2]
Harvesting
Hips are picked in autumn once fully coloured, then dried for tea or powder, or processed fresh for syrup. The fine, irritant hairs surrounding the seeds inside the hip must be removed before consumption.[5]
Flowers/petals are picked as they open in summer; hips are picked in autumn once fully coloured and slightly softened.[2]
Traditional Uses
Rosehip has a long European folk tradition as a vitamin-C-rich tonic for colds and general immunity, and as a mild diuretic and astringent for urinary and digestive complaints. Modern clinical trials on standardised rosehip powder show a modest, reproducible benefit for osteoarthritis pain and stiffness.[1, 2]
Rosa rugosa has a long East Asian tradition - particularly in Traditional Chinese Medicine, where the flower is known as 'Mei Gui Hua' - as a mood-regulating, digestive and menstrual-cycle-supporting remedy, and the vitamin-C-rich hips are used as a food tonic. Modern research on its flavonoid- and polysaccharide-rich extracts supports broad antioxidant, anti-inflammatory, hepatoprotective and immunomodulatory activity.[2]
Preparations
The form used in osteoarthritis clinical trials.
Dosage
Clinical trials for osteoarthritis have most often used around 5 g/day of standardised rosehip powder. Educational reference only, not a prescription.
Traditional guidance suggests roughly 3-6 g dried flower per cup as an infusion, or hip tea/syrup at similar strength, taken once or twice daily. Educational reference only, not a prescription.
