Extracts of Black cohosh (Cimicifugae rhizoma) have been used for the treatment of climacteric complaints for decades. A significant number of woman entering menopause exhibit the following symptoms: getting hot flushes, night sweats, irritability, depression, and anxiety, A reduction of the frequency of hot flushes equivalents and hints on the antidepressant activity of Cimcifuga extracts. In the present work, we have screened several 80% ethanol extracts from medicinal plants and found that the extracts from Cimicifugae Rhizoma(Black cohosh:승마) have inhibitory effect on catecholamine secretion in bovine chromaffin cell. Since this extract inhibited 1,1-dimethyl-4-phenylpiperazinium iodide (DMPP)-induced catecholamine secretion, but did not inhibit KCl, bradykinin, and veratridine-evoked case, this inhibitory effect is mediated by nicotinic acetylcholine receptors with noncompetitive manner.

PURPOSE. The purpose of this study was to evaluate bone response to anodized titanium implants coated with the extract of black cohosh, Asarum Sieboldii, and pharbitis semen. MATERIALS AND METHODS. Forty anodized titanium implants were prepared as follows: group 1 was for control; group 2 were implants soaked in a solution containing triterpenoids extracted from black cohosh for 24 hours; group 3 were implants soaked in a solution containing extracts of black cohosh and Asarum Sieboldii for 24 hours; group 4 were implants soaked in a solution containing extracts of pharbitis semen for 24 hours. The implants from these groups were randomly and surgically implanted into the tibiae of ten rabbits. After 1, 2, and 4 weeks of healing, the nondecalcified ground sections were subjected to histological observation, and the percentage of bone-to-implant contact (BIC%) was calculated. RESULTS. All groups exhibited good bone healing with the bone tissue in direct contact with the surface of the implant. Group 2 ($52.44{\pm}10.98$, $25.54{\pm}5.56$) showed a significantly greater BIC% compared to that of group 3 ($45.34{\pm}5.00$, $22.24{\pm}2.20$) with respect to the four consecutive threads and total length, respectively. The BIC% of group 1 ($25.22{\pm}6.00$) was significantly greater than that of group 3 ($22.24{\pm}2.20$) only for total length. CONCLUSION. This study did not show any remarkable effects of the extract of black coshosh and the other natural products on osseointegration of anodized titanium implants as coating agents. Further studies about the application method of the natural products on to the surface of implants are required.

Purpose: Menopausal syndrome is caused by urgent changes of sex hormone in women. The hormonal therapy can soothe the problems of menopausal patients, but it can increase the probability of another disease, such as breast cancer, heart attack, etc. So the demand of alternative herb therapy is increasing in Western countries. In Korea, herbal medicine is imported and used by Western doctors. To know and use the alternative herbal medicine, Korean Medical doctors should know their efficacy and safety. Methods: We researched the Medline(Pubmed) with the key word such as 'CAM', 'herb' and 'menopause'. We selected the herbs known as treating the menopausal syndrome and researched the similar or same herbs that are used in Korean medicine by the scientific name and efficient ingredients. To evaluate the efficacy of the herbs, we compared the herbs that were differently defined in alternative and Korean medicine Results: Balm, black cohosh, chaste berry, dong quai. evening primrose oil. ginkgo, St. John's wort, valerian root, and sarsaparilla were chosen as prevalent herbs used in alternative medicine. The pharmacologic effect of Black cohosh, licorice root, St. John's wort were recognized. But these three herbs are not usually prescripted for menopausal patients in Korean medicine. So we could apply these three herbs as one of Korean medical treatments. The efficacy of other herbs cannot be surely prescripted for menopausal patients. Conclusion: The efficacy and safety of alternative medicine is not proved yet. But to diversify the treatmental methods of Korean medicine, we need to prove and use these medicine as one of Korean medical treatment.

Objectives : We present some opinions to reduce the risk of herb-drug interactions through scanning "About Herbs" of the Memorial Sloan Kettering Cancer Center Website. Methods : We searched the Memorial Sloan Kettering Cancer Center Website of About Herbs and investigated herb-drug interactions. Results : There are 237 herbs and 196 drugs on About Herbs. 81.1% of herbs have fewer than 2 interactions listed.: 86.3% of drugs fewer than 3 interactions. Especially, 13 herbs were reported to have interactions with inclusive chemoagents on About Herbs. Only L-theanine has positive interaction with inclusive chemoagents. The others have negative interactions with inclusive chemoagents. 12 single chemoagents were reported to have interactions with some herbs. Especially tamoxifen-black cohosh, methotrexate-glutamin and aldesleukin-Huang Chi have positive interactions to increase the effects of the chemoagent. Conclusions : We should urgently create a risk management system of herb-drug interactions and take note of the risk of herb-drug interactions. We should build up systemic, evidence-based informations on popular herbs used by Korean cancer patients and herb-drug interactions in oncology like About Herbs.

Cimicifuga racemosa (Black cohosh) has been used as therapeutics for pain and inflammation in Korean folk medicine. The potential effects of cimicifuga racemosa extract on mast cell dependent allergy reaction, however, have not been well elucidated yet. In the present study, we investigated the effect of cimicifuga racemosa extract on the allergy reaction using mast cell dependent in vivo and in vitro models. The oral administration of cimicifuga racemosa extract showed inhibitory potential on the compound 48/80 induced active systemic anaphylactic shock. cimicifuga racemosa extract also significantly inhibited the anti DNP IgE induced passive cutaneous anaphylaxis (PCA) reaction and acetic acid induced vascular permeability. In addition, cimicifuga racemosa extract inhibited the beta hexosaminidase release and TNF alpha and IL 4 mRNA induction by DNP HSA in rat leukemia mast cells, RBL 2H3. but cimicifuga racemosa extract didn't affected to RBL 2H3 cell viability. These results demonstrated that cimicifuga racemosa extract has an anti allergic potential and it may be due to the inhibition of histamine release and cytokine gene expression in the mast cells.

The medicinal plant Cimicifuga Racemosa (Black cohosh) has been used to treat many kinds of neuronal and menopausal symptoms, such as arthritis, menopausal depression, nerve pain, etc. Here, we examined the effect of Cimicifugoside (CF), one of triterpene glycosides which have been known as pharmacologically active ingredients of C. Racemosa, on nicotinic acetylcholine receptor (nAChR)-mediated catecholamine (CA) secretion in bovine adrenal chromaffin cell. Cimicifugoside inhibited calcium increase induced by 1,1-dimethyl-4-phenylpiperazinium iodide (DMPP), a nAChR agonist with a half maximal inhibitory concentration (IC50) of 18${\pm}$2${\mu}$M. In contrast, cimicifugoside did not affect the calcium increases evoked by high K$\^$+/, veratridine, and bradykinin. The DMPP-induced sodium increase was also inhibited by cimicifugoside with IC50 of 2${\pm}$0.3${\mu}$M, suggesting that the activity of nAChRs is inhibited by cimicifugoside. Cimicifugoside did not effect on the KCl-induced secretion but markedly inhibited the DMPP-induced catecholamine secretion which was monitored by carbon-fiber amperometry in real time, and by high performance liquid chromatography (HPLC) through electrochemical detection. The results suggest that cimicifugoside selectively inhibits nAChR-mediated response in bovine chromaffin cells.

Actein is the well-known active ingredient of Cimicifugae rhizoma (Black cohosh). In this study, we investigated and compared the binding affinity of tubocurarine, actein, and actein derivatives on the B&C domain of the acetylcholine binding protein through in silico computational docking studies. The three-dimensional crystallographic structure of the acetylcholine binding protein B&C domain was obtained from the PDB database (PDB ID: 2XYT). An in silico computational autodocking analysis was performed using PyRx, Autodock Vina, Discovery Studio Version 4.5, and NX-QuickPharm based on scoring functions. The actein showed an optimum binding affinity (docking energy), with the acetylcholine binding protein at -10.50 kcal/mol as compared to the tubocurarine (-9.80 kcal/mol). The interacting amino acids tryptophan 84 and tryptophan 147, in the B domain of the acetylcholine binding protein active site, significantly interacted with the actein and 27-deoxyactein, and (26R)-actein. The centroid XYZ grid position of the tubocurarine was X=38.300689, Y=112.053467, and Z=51.991022, but the actein and its derivatives showed values around X=26.4, Y=127.3, Z=43.7. These results clearly indicated that actein and its derivatives could be a more potent antagonist to the acetylcholine binding protein than tubocurarine. Therefore, the extract of Cimicifugae rhizoma or actein containing biomaterials can substitute for the botulinum toxin-mediated acetylcholine receptor regulation, and be applied to the anti-wrinkle cosmetics industry.
