What are the morphological characteristics of this plant?
Rubus coreanus has arching, deciduous canes that are characterized by small, sharp prickles and alternate, trifoliate leaves with serrated margins. The foliage consists of three leaflets that are typically ovate in shape and possess a slightly hairy texture on the underside. During the flowering season, the plant produces small, five-petaled white flowers that emerge from the axils of the leaves. These blossoms eventually develop into aggregate fruits known as blackberries, which transition from green to a deep, glossy black when fully ripe. The root system is perennial and allows the plant to spread through its woody stem structure.
What is the geographical distribution of this plant?
This plant is native to the Korean Peninsula, where it is widely distributed across the various provinces of South and North Korea. It primarily thrives in temperate regions characterized by hilly landscapes and mountain slopes. Within these habitats, the species is often found in forest edges, thickets, and sunny openings where it can access sufficient light. Its range is concentrated in East Asia, specifically favoring the moist, well-drained soils typical of the Korean terrain. Because it is indigenous to this specific area, it is a common component of the local wild flora.
How is this plant cultivated?
This plant Rubus coreanus requires well-drained, slightly acidic soil and full sun exposure to produce high yields of its edible berries.
Gardeners should plant it in temperate climates where it can establish a strong root system during the spring. Regular pruning is necessary to remove old canes and encourage the growth of new, productive stems. Providing consistent moisture through mulch helps prevent the soil from drying out too quickly during hot months.
Once established, the plant is relatively hardy and can thrive with minimal intervention.
What parts of this plant are used medicinally?
This plant Rubus coreanus utilizes its leaves, stems, and fruit for various medicinal applications in traditional practices. The leaves are often decocted into teas to address inflammation and support digestive health. Its stems can be processed to aid in treating skin ailments or reducing swelling. The fruit is consumed not only for nutrition but also for its potential antioxidant properties. Each part provides unique bioactive compounds that contribute to its therapeutic reputation.
According to a study published by "The American journal of Chinese medicine", the unripe fruit of Rubus coreanus is used as a medicinal extract. This Rubus coreanus fruit extract inhibits the uptake of Dil-labeled oxLDL by murine macrophage cells in a dose-dependent manner. The extract also inhibits JNK phosphorylation in macrophages treated with oxLDL in both a time- and dose-dependent manner. These results suggest that the inhibition of JNK phosphorylation is the likely mechanism for the RCE-induced inhibition of oxLDL uptake.

According to a study published by "Journal of ethnopharmacology", Rubi Fructus (RF) is the dried, unripe fruit of Rubus coreanus M IQ. (Rosaceae). This plant has been used in traditional Korean medicine to improve male reproductive function. In the study, RF was administered to 8-week-old male Wistar rats for 56 consecutive days at a dose of 1.0 g/kg daily via p.o. administration. The RF-treated animals showed significant increases in the weight of the testes, epididymal sperm count, and sperm motility. Additionally, RF increased the expression of CREM at both the mRNA and protein levels.

According to a study published by "Archives of pharmacal research", methanol extract from Rubus coreanus significantly inhibits VEGF binding to the VEGF receptor with an IC50 of approximately 27 microg/mL. Among examined fractions, the aqueous fraction showed potent inhibitory effects against the binding of KDR/Flk-1-Fc to immobilized VEGF165 with an IC50 of approximately 11 microg/mL. Sanguiin H-6 was isolated as an active principle from this aqueous fraction and inhibited the binding of KDR/Flk-1-Fc to immobilized VEGF165 with an IC50 of approximately 0.3 microg/mL. Furthermore, sanguiin H-6 efficiently blocked VEGF-induced HUVEC proliferation in a dose-dependent manner with an IC50 of approximately 7.4 microg/mL. This compound had no effect on the growth of HT1080 human fibrosarcoma cells.
The primary pharmacological activities of this plant are shown in the list below.
