Key Constituents
The major storage carbohydrate; a prebiotic fibre.
Anti-inflammatory and antioxidant constituents.
Antimicrobial and antioxidant 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.
Pharmacological Actions
Traditional 'alterative' / depurative for chronic skin conditions - eczema, psoriasis, acne and boils (internally and topically)
Lesser burdock (Arctium minus) leaf, flower and root extracts (rich in arctiin/arctigenin and chlorogenic acid) are cytotoxic to breast and liver cancer cells, including multidrug-resistant tumour lines (preclinical).
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
Sebaceous-gland regulator - helps balance skin oil (acne); Traditional 'alterative' / depurative for chronic skin conditions - eczema, psoriasis, acne and boils (internally and topically)
inferred from anti-inflammatory action
Arctium minus extracts show dose-dependent cytotoxicity against MCF-7 and MDA-MB-231 breast cancer and HepG2 liver cancer cells and are active against both sensitive and multidrug-resistant tumour cell lines (preclinical).
Mild diuretic supporting elimination ('detox', traditional); Traditional 'alterative' / depurative for chronic skin conditions - eczema, psoriasis, acne and boils (internally and topically)

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.

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
As a member of the daisy family (Asteraceae), it can cause allergic reactions in people sensitive to ragweed and related plants. The high inulin content can cause temporary bloating or gas.
May lower blood sugar (caution with antidiabetic medicines) and add to diuretics; avoid medicinal doses in pregnancy.
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).
External Ids
Botanical Description
Biennial herb closely related to greater burdock, forming a first-year rosette of large, heart-shaped, long-stalked leaves, green above and grey-woolly beneath, generally smaller than Arctium lappa. In the second year it produces a branching flowering stem with smaller purple thistle-like flower heads in a looser, more sprawling habit, each enclosed in a globe of hooked bracts that ripen into clinging burrs.[15]
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]
Habitat
A common weed of waste ground, roadsides, hedgerows and disturbed soil; native to Europe and widely naturalised in North America, where it is often the most common wild burdock species.[15]
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]
Harvesting
The root is dug at the end of the first growing season or early in the second spring, before flowering; leaf may be gathered through the first year. Careful identification against deadly nightshade, whose root can resemble burdock, is essential before digging.[15]
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]
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]
