The complete database record: 4 documented constituents, 3 pharmacological actions, 7 traditional / indicated uses, with 24 cited sources.

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]

Habitat & Distribution

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

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]

Parts: Fruit (hip), Petals, Seed
Season: Autumn

Key Constituents

Vitamin C and carotenoids[5, 14]

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.

Carotenoids
Galactolipid (GOPO)[2]

A specific galactolipid fraction studied as the likely active anti-inflammatory constituent in osteoarthritis trials of standardised rosehip powder.

Flavonoids and tannins[4, 15]

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.

FlavonoidsTannins
Seed oil (unsaturated fatty acids, tocopherols, phytosterols)[16]

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.

Phytosterols

Pharmacological Actions

Anti-inflammatory[1, 2, 17, 18]

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.

Anticancer (preclinical)[4]
Antioxidant[2, 4, 5, 6, 7, 9, 14, 15, 17, 18]

Traditional & Indicated Uses

Arthritis / joint pain[1, 2, 17, 19, 20]Strong · 10/10

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.

Cognitive function[21]Preliminary · 2/10

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.

Urinary tract infection (UTI)[22]Moderate · 5/10

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.

Traditional Use & History

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]

Preparations

Rosehip powder (standardised, seedless)[1]

The form used in osteoarthritis clinical trials.

Dosage

Rosehip powder[1]

Clinical trials for osteoarthritis have most often used around 5 g/day of standardised rosehip powder. Educational reference only, not a prescription.

Safety, Cautions & Contraindications

Safety note[17, 23]Info

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.

Safety note[17, 23, 24]Info

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).

Harvest Readiness

[13]

Part: fruit
Signals: Gather the hips in autumn (late summer to October), when ripe red and softened by the first frosts.
Basis: traditional
Source Quote: Rose hips are typically harvested in late summer to early autumn, usually from August to October
Species Confirmed: 1
Notes: PFAF (REF-3322); the hips are gathered in autumn, softened and sweetened by frost. Single lineage -> provisional.

[13]

Part: seed
Signals: Collect the seeds (achenes) from the ripe hips in autumn to early winter.
Basis: traditional
Source Quote: the seeds ripen from October to December
Species Confirmed: 1
Notes: PFAF (REF-3322); the seeds ripen in the autumn/early-winter hips (October-December). Single lineage -> provisional. (The petals, also a listed part, were not separately timing-sourced this pass - gathered in early summer while in flower.)
