Safety, Cautions & Contraindications

Safety note[11, 13]Caution

Lower urinary tract / prostate symptoms must be medically assessed first to exclude prostate cancer. The evidence is mixed and rests on small, short, methodologically weak trials, so men with moderate or severe BPH should not rely on it instead of proven treatment.

Safety note[11]Info

Generally well tolerated, with mild gastrointestinal effects the most common report.

Safety note[11, 12, 13]Caution

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.

Safety note[11, 12, 13, 14]Info

Duke (2002) does not include a dedicated entry for Japanese rose (Rosa rugosa) in the Handbook of Medicinal Herbs, Second Edition.

Botanical Description

Evergreen tree (Rosaceae), 10-30 m tall, with dark, fissured, red-brown bark (the source of the common name 'red stinkwood', from its unpleasant smell when cut). Leaves are glossy dark green, leathery, oblong with finely toothed margins. Small white, five-petalled flowers are borne in axillary racemes, followed by small reddish-brown, two-lobed fruit.

Height: 10-30 m
Habit: Evergreen tree
Leaves: Glossy dark green, leathery, oblong, finely toothed
Flowers: Small, white, five-petalled, in axillary racemes
Stem: Dark, fissured, red-brown, aromatic bark
Root: Deep woody root system
Fruit: Small, reddish-brown, two-lobed fruit
Flowering Period: Variable, often twice yearly in its native range

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]

Height: 1-1.5 m (occasionally to 2 m)
Habit: Dense, thicket-forming deciduous shrub
Leaves: Pinnate, 5-9 deeply veined, glossy, leathery leaflets
Flowers: Large, fragrant, deep pink to white, five-petalled
Stem: Densely covered in numerous straight, bristly thorns
Root: Woody, suckering root system
Fruit: Large, tomato-red, flattened-globose hips
Flowering Period: June-September

Habitat

Native to montane forests of central and southern Africa (and Madagascar), growing at moderate to high altitude (roughly 900-3400 m). The species is CITES-listed and conservation-threatened owing to over-harvesting of bark for the pharmaceutical trade.

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

Bark is traditionally stripped from mature trees. Unsustainable stripping - especially removing bark all the way round the trunk - kills the tree and has driven population decline, so sustainable, partial and rotational bark harvesting or cultivated sources are recommended.

Parts: Bark
Season: Not standardised; sustainable/rotational harvesting recommended

Flowers/petals are picked as they open in summer; hips are picked in autumn once fully coloured and slightly softened.[2]

Parts: Flower, Fruit, Petals
Season: Flower in summer; hips in autumn

Traditional Uses

Prunus africana bark has a traditional use in East and Central African ethnomedicine for urinary complaints, and its extract (marketed as Pygeum) became one of the most widely used European phytotherapy remedies for benign prostatic hyperplasia (BPH) symptoms in the 20th century. Clinical evidence for symptom benefit is moderate but drawn from small, methodologically weak trials.[11]

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

Standardised lipophilic bark extract (capsule)[11]

The clinically studied commercial form, standardised for phytosterol content.

Flower tea/infusion[2]

Dried petals or flower buds steeped in hot water - the classic Traditional Chinese Medicine preparation.

Standardised extract[1, 2]

Concentrated flavonoid/polysaccharide extract used in research.

Dosage

Standardised extract[11]

Clinical trials have most often used around 100-200 mg/day of standardised lipophilic bark extract, divided into two doses. Educational reference only, not a prescription; any prostate or urinary symptom should be medically assessed first.

Flower infusion[2]

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.
