Epimedium, Hb. – YIN YANG HUO – Elfenblumenkraut
Epimedium ist ein Qi-Aufbauer der Niere mit dem Schwerpunkt des Aufbaus von Sexualhormonen.
Durch die so gewährleistete bessere Versorgung aller Organe ist es ein Mittel gegen vorzeitige Alterung. Die Verminderung von Entzündungsbereitschaft führt zu einer gesteigerten Fähigkeit Schleim in Gehirn und Gefäßen aufzulösen und zu entsorgen.
- Icariin and its derivative, ICT, exert anti-inflammatory, anti-tumor effects, and modulate myeloid derived suppressive cells (MDSCs) functions
In conclusion, our results showed that ICA, and more robustly, ICT, directly modulate MDSC signaling and therefore altered the phenotype and function of these cells, in vitro and in vivo
- Antiinflammatory effects of Epimedium brevicornum water extract on lipopolysaccharide-activated RAW264.7 macrophages
These results suggest that EB has antiinflammatory activity related to its inhibition of NO, cytokine, chemokine and growth factor production in macrophages
- Regulation of inflammatory mediators in lipopolysaccharide-stimulated RAW 264.7 cells by 2“-hydroxy-3“-en-anhydroicaritin involves down-regulation of NF-kappaB and MAPK expression.
The flavone also inhibited p65-NF-kappaB translocation into the nucleus by I kappaB alpha degradation. Therefore, 2“-hydroxy-3“-en-anhydroicaritin may inhibit LPS-induced production of inflammatory cytokines by blocking NF-kappaB and MAPK signaling in RAW264.7 cells.
- Desmethylanhydroicaritin inhibits NF-kappaB-regulated inflammatory gene expression by modulating the redox-sensitive PI3K/PTEN/Akt pathway.
These results indicate that DMAI negatively regulates canonical NF-kappaB-regulated inflammatory gene expression by functioning as an inhibitor of the NF-kappaB pathway through the suppression of redox-based PI3K activation and PTEN inactivation and therefore can be considered as a potential drug for inflammatory diseases.
- Comparison research with icariin and genistein by anti-inflammatory reaction and angiogenesis pathway to inhibit bone loss on ovariectomized rats.
Icariin inhibits bone loss on model rat through suppressing bone resorption. Genistein prevents bone loss on model rat by the pathway of inhibiting inflammatory reaction, activating angiogenesis, enhancing bone formation and inhibiting bone resorption. Moreover, pharmacological activity of genistein is more potential than icariin.
YYH-C can effectively control the bone mass loss of rats with ovariectomy-induced osteoporosis, prevent the changes in bone microstructure, and inhibit bone absorption, so as to resist high turn-over osteoporosis after ovariectomy. [Key words] total flavones of Epimedium leptorrhizum; ovariectomized rat; osteoporosis
- Erectogenic and neurotrophic effects of icariin, a purified extract of horny goat weed (Epimedium spp.) in vitro and in vivo.
Rats treated with low-dose ICA demonstrated significantly higher ICP/MAP and AUC/MAP ratios compared with control and single-dose ICA animals. Immunohistochemistry and Western blot were revealing of significantly greater positivity for nNOS and calponin in penile tissues of all rats treated with ICA. ICA led to significantly greater neurite length in cultured specimens of pelvic ganglia
It was established that oral administration of lipid-based suspension of dry extract of Epimedium koreanum in wheat germ oil improved erectile function of aged rats.
- Icariin Intervenes in Cardiac Inflammaging through Upregulation of SIRT6 Enzyme Activity and Inhibition of the NF-Kappa B Pathway
ICA upregulated the expression of SIRT6 and had an inhibitory effect on NF-κB inflammatory signaling pathways as shown by decreasing mRNA levels of the NF-κB downstream target genes TNF-α, ICAM-1, IL-2, and IL-6. Those effects were mediated directly or indirectly by SIRT6. We provided evidence that inflammaging may involve a novel link between the effects of ICA on SIRT6 (a regulator of aging) and NF-κB (a regulator of inflammation).
- Metabonomic characterization of aging and investigation on the anti-aging effects of total flavones of Epimedium.
All important age-related metabolites, such as unsaturated fatty acids, saturated fatty acids, nucleotides, carnosine, ergothioneine and amino acids, displayed age-related changes, and most of them were reset to a younger level after TFE administration. This study indicated that aging could be characterized by changes of lipid metabolisms and accumulation of free radicals. The anti-aging effects of TFE might due to the intervention on lipid metabolism and its property of anti-oxidation.
As compared with the blank group, the mean lifespan in the two EF group and the maximum lifespan in the high dose EF group were higher, and the age-dependent mortality in the high dose EF group was lower significantly (P<0.05 or P<0.01); as compared with the CR group, the mean lifespan and maximum lifespan in the high dose EF group were higher (P<0.01); but no significant difference of the subalgebra between the blank group and the high dose EF group was shown (P>0.05). Compared with the blank group, the mean lifespan in the high dose EF group was significantly prolonged under acute heat-stress at 35 degrees C (P<0.01).
- Metabonomic study on ageing: NMR-based investigation into rat urinary metabolites and the effect of the total flavone of Epimedium
The result suggests that TFE administration can markedly influence the ageing process and shows anti-ageing effects, which might due to the melioration of pyruyate metabolism and oxidative phosphorylation.
- Experimental study on effect of epimedium flavonoids in protecting telomere length of senescence cells HU
In senescence human fibroblasts 2BS cells, p16 gene mRNA expression increased, content of phosphorated Rb protein decreased and the telomere length of 2BS shortened, EF might delay the aging of cells through inhibiting the p16 gene expression, promoting the production of phosphorated Rb protein and to protect the length of telomere, but not activating the telomerase.

Neuroprotective effect of the active components of three Chinese herbs on brain iron load in a mouse model of Alzheimer’s disease.
Thus, the present study indicated that the active components of Epimedium, Astragalus and Radix Puerariae may exert a neuroprotective effect against AD by reducing iron overload in the AD brain and may provide a novel approach for the development of drugs for the treatment of AD.
