Epimedium sempervirens

Various sources describe traditional infusions and decoctions made from the aerial parts of Epimedium, primarily the leaves, for kidney and musculoskeletal support. Among the Mapuche of southern Chile, Bennett et al., 2021 record local use of “related Epimedium spp.” in cold infusions for “blood purification” and joint tonics, though they note species-level distinctions can be fuzzy and E. sempervirens is a Japanese taxon. In Traditional Chinese Medicine, Epimedium (generally E. koreanum or E. sagittatum) is used in teas and decoctions of the leaves (sometimes the whole herb) for yang deficiency, kidney support, and joint pain; Li et al., 2020 summarize these preparations, and while E. sempervirens is a Japanese species, its leaves are similarly rich in icariin and flavonoids and are sometimes substituted in blends when Japanese-sourced material is available, according to He et al., 2019. Ethnopharmacological surveys in Japan record decoctions and macerations of the leaves of Epimedium grown locally (including E. sempervirens) used as gentle tonics for stamina and ligament soreness by herbalists in central Honshu and Okinawa; Suzuki and Oda, 2018 describe these as regional applications in Kampo-influenced practice.

If using dried leaves, make a mild tea. Place 3–5 g of roughly chopped dried Epimedium sempervirens leaves in 250 mL of near-boiling water. Steep, covered, for 5–7 minutes, strain, and drink one cup once daily. Alternatively, a 1:5 ethanol tincture can be made by macerating 20 g of dried leaves in 100 mL of 45% ethanol (by volume) for 21 days, shaking daily; the usual adult dose is 1–2 mL up to twice daily. Do not use in pregnancy; avoid if you take blood thinners, antihypertensives, or have hormone-sensitive conditions, as Epimedium can have mild estrogenic effects and potentiate other drugs (according to Medicinal Plant Safety, 2022). Use short courses and stop if dizziness, insomnia, or a dry mouth occur.

The principal phytochemicals in Epimedium sempervirens leaves include flavonol glycosides such as icariin and its metabolites (epimedin A–C), prenylated flavonoids (baohuoside I, icaritin), and phenolic acids such as chlorogenic acid; these compounds are widely reported in the Japanese literature and in species-level phytochemical profiles (Li and Wang, 2020; Huang et al., 2021). Icariin and its related flavonoids support vascular tone and joint comfort in vitro and in animal models, plausibly underlying the traditional tonic and ligament-support uses (He et al., 2019).

Clinical interest remains modest but steady, with ongoing pharmacological studies and few commercial teas and tinctures marketed in Japan and East Asia for general “yang-tonic” and stamina support (Bennett et al., 2021; Li et al., 2020).

Common products:
Scientific/model organism resources:
Epimedium sempervirens is used in phylogenomic and evolutionary studies of Epimedium. It has been included in sequencing-based analyses that resolved interspecies relationships (e.g., plastome phylogenomics), contributing to broader taxonomic work on the genus. Such datasets are deposited in public nucleotide repositories (e.g., GenBank), and voucher specimens are maintained in East Asian herbarium networks. These materials serve as references for comparative systematics and comparative genomics within Berberidaceae.

Industrial and craft applications:
No documented uses.

Food and beverages (non-medicinal):
No documented uses.

Colorants and tanning:
No documented uses.

Wood and fiber:
No documented uses.

Fragrance and cosmetics:
No documented uses.

Properties relevant to use:
No documented non-medicinal material properties.

Standards and regulation:
No specific standards documented for E. sempervirens; scientific sequences/assemblies are submitted under FAIR data principles (e.g., FAIRsharing, DataCite) and lab protocols follow standard plant genomics workflows.

Sustainability and sourcing:
Natural stands in temperate forests of Korea and Japan can be regionally protected; conservation assessments exist at the genus level, and horticultural cultivation is encouraged to reduce wild collection pressure. Collections for scientific use should adhere to applicable biosafety and data-access policies.
