Safety, Cautions & Contraindications

Safety note[14]Info

Tannin-rich: high or prolonged intake may cause stomach upset or constipation and can reduce the absorption of iron and some medicines taken at the same time.

Safety note[14]Caution

Diarrhoea persisting more than 3-4 days, or with fever or blood in the stool, needs medical care. Use in pregnancy and breastfeeding is not recommended in the absence of data.

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

Low, sprawling to semi-erect perennial herb (Rosaceae) with wiry stems. Leaves are palmate, typically with 4-5 leaflets and large leaf-like stipules that give the impression of more leaflets. Flowers are small, yellow and four-petalled - unusual among Potentilla species, most of which have five petals. The thick, woody rhizome is reddish inside when cut, the origin of the old name 'bloodroot' for this European species.[14]

Height: Low, sprawling to semi-erect, stems to about 30-45 cm
Habit: Low, sprawling to semi-erect perennial herb
Leaves: Palmate, typically 4-5 leaflets, with large leaf-like stipules
Flowers: Small, yellow, four-petalled (unusual among Potentilla species)
Stem: Wiry, sprawling to semi-erect
Root: Thick, woody rhizome, reddish inside when cut
Fruit: Small dry achenes (typical Rosaceae)
Flowering Period: May-September

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 to Europe and western Asia, common in acidic grassland, heath, moorland, open woodland and pastures on poor, well-drained soils.[14]

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

The rhizome is dug in autumn or early spring, when tannin content is highest, then cleaned and dried.[14]

Parts: Rhizome
Season: Autumn or early spring

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

Tormentil rhizome has an official European herbal-monograph tradition for mild diarrhoea and inflammation of the mouth and throat, reflecting its long folk use as a powerful astringent for gut and mucous-membrane complaints. Modern trials confirm its ellagitannin-rich rhizome shortens the duration of infectious (rotavirus) diarrhoea.[8, 14, 15]

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

Decoction[14]

Dried rhizome simmered in water, the standard astringent preparation for diarrhoea.

Tincture[15]

Alcoholic extract, taken diluted or used as a gargle/mouthwash.

Gargle/mouthwash[15]

Diluted decoction or tincture used for sore throat and mouth inflammation.

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

Decoction/tincture[14, 15]

EMA/ESCOP guidance suggests around 4-6 g dried rhizome (or an equivalent decoction), divided into 2-3 doses daily, for diarrhoea, or a diluted tincture used as a gargle several times daily. Educational reference only, not a prescription.

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.
