Botaaniline kirjeldus
Verev kurereha on mitmeaastane rohttaim kurerehaliste sugukonnast, perekonnast kurereha. Taim võib kasvada kuni 50 cm kõrguseks. Taime varred on kaetud pikkade harali karvadega. Vars ise on püstine või lamav, see hargneb, moodustades kompaktse ja kohevama puhma. Lehed on sõrmjagused (tavaliselt 5-7 jaoga), millest iga jagu on omakorda kaheks jagunenud. Lehe iseloomulik harunemine eristab teda teistest perekonna liikidest.  [1,2] Õieraod on enne ja pärast õitsemist longus, kuid õitsemise ajal muutuvad need püstiseks. Õiekate kaheli, viietine. Tupplehed lahklehised, elliptilised, karvased, tipust pika teritunud lineaalse jätkega. Õiekroon lahklehine, kuni 2 cm läbimõõduga, purpurpunane, naastukesed pügaldunud. Tolmukaid 10, tolmukaniidid tumeroosad kuni lillad. Emakas on viietine, harunenud viieks sissepoole kaardus emakakaelaks. Õitsemisperiood kestab tavaliselt maist oktoobrini. Vereva kurereha õied on hermafrodiitsed. Taime tolmeldavad putukad, eriti kärbsed. Taime vili on kuiv jaguvili, mis küpsemisel lagunevad viieks osaviljaks.  [1,2] 

Levila
Taim on pärit Euroopast ja parasvöötme Aasiast. See on laialt levinud suuremas osas Euroopast kuni Kaukaasiani. Kirde-Iirimaal on see harv aiapõgenik. [2] Kasvukohana eelistavad kaunid õitsejad lubjarikkaid ja kuivi muldasid, seega Läänemaad, saari ja Põhja-Eestit. [3] 

Toime ja kasutamine
Taimes leidub flavonoide, katekiine, polüfenoolhapet ja kondenseerunud tanniine. Ekstraktil on herpese viirust inhibeeriv toime.  [4]

Botanical Description
The bloody crane´s-bill (Geranium sanguineum) is a perennial herbaceous plant from the Geraniaceae family and the Geranium genus. The plant can grow up to 50 cm tall. Its stems are covered with long, spreading hairs and are upright or sprawling, branching to form a compact and bushy clump. The leaves are palmately divided (typically with 5–7 lobes), each lobe further divided into two segments. This distinctive leaf branching differentiates it from other species in the genus. [1,2]

Flower stalks droop before and after flowering but become upright during blooming. The perianth is double-layered and five-parted. The sepals are free, elliptical, hairy, and tipped with a long, pointed linear extension. The petals are free, up to 2 cm in diameter, purple-red, and notched at the apex. The plant has 10 stamens with filaments that are dark pink to purple. The ovary is five-parted, with five inwardly curved styles. The flowering period usually lasts from May to October. The flowers of the bloody cranesbill are hermaphroditic and are pollinated by insects, especially flies. The fruit is a dry schizocarp that splits into five mericarps upon ripening. [1,2]

Distribution
The plant is native to Europe and temperate Asia and is widespread across most of Europe, extending to the Caucasus. In northeastern Ireland, it is a rare garden escapee. [2] This attractive flowering plant prefers calcareous and dry soils, making it well-suited to western Estonia, the islands, and northern Estonia. [3]

Effects and Uses
The plant contains flavonoids, catechins, polyphenolic acids, and condensed tannins. Extracts from the plant have been found to inhibit the herpes virus. [4]
