Key Constituents
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.

Safety, Cautions & Contraindications
Contains cardiac glycosides: do NOT use in pregnancy, breastfeeding or infancy, in anyone with a heart condition, or alongside cardiac glycoside medicines (e.g. digoxin). The plant's cardenolide-rich latex is directly toxic - a documented case caused corneal injury through Na/K-ATPase inhibition.
Large doses are emetic and purgative (cause vomiting and diarrhoea). There is very little modern safety or efficacy data, so use only under the guidance of a qualified practitioner.
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
Erect perennial herb with hairy, unbranched stems and narrow, lance-shaped, alternate leaves (unlike most milkweeds, its sap is clear rather than milky). Vivid orange-red flowers are borne in showy, flat-topped umbel-like clusters at the stem tips, making it a prized butterfly and pollinator plant. The stout, fibrous, branching root is the medicinal part.[11]
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 dry prairies, open fields, roadsides and sandy or rocky open ground across most of eastern and central North America.[11]
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 root is dug in autumn after the plant has finished flowering and seeding, then cleaned and dried; given its cardiac glycoside content and near-absence of modern safety data, harvesting and use should only be undertaken with expert guidance.[11]
Flowers/petals are picked as they open in summer; hips are picked in autumn once fully coloured and slightly softened.[2]
Traditional Uses
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
Dried root simmered in water as a traditional expectorant and diaphoretic remedy; given its cardiac glycoside content, only under qualified practitioner guidance.
Dosage
Because the root contains cardiac glycosides and modern safety/efficacy data are very limited, no general dose is given here; use only under the guidance of a qualified practitioner, and never in pregnancy, breastfeeding, infancy, or with a heart condition or cardiac glycoside medicines. 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.
