how much black cohosh for miscarriage

Black Cohosh: Benefits, Dosage, Side Effects, and MoreAdvert Supported byFacing My Second Unwanted PregnancyBy Lucy Ferriss I knew I was pregnant for the second time at 86th Street Metro Station. This was before the mobile phones. I left the train at 5:28; the clinic closed at 5:30. I called from the pay phone on the platform, my finger pressed against an ear while I was collapsing for the news. "Positive!" the nurse at the other end kept screaming, while I refused to understand. Two years earlier, pregnant by a husband who did not love, I chose to finish — first pregnancy, then marriage. Ardent for the reproductive choice, I could not anticipate the pain I would suffer later. The nightmares harassed me. I swore never to repeat the procedure. But here he was — single, barely scratching in Manhattan and pregnant. The first time, the error was the diaphragm, two sizes too small. This time, a condom broke up during my first intimate encounter with an older boy who was happy to ask me about New York but would have fled in a baby's news. I was well educated, liberal, feminist and rational to a failure. But when I crawled home from the subway, I called my friend from New Age Nancy and asked her "the recipe." Nancy had told me there was a way to induce herbal abortions. Miscarriage seemed more natural than an abortion, like something that just happened to you, not something you chose. The next day, during my lunch hour, I chose my way through the fusion of piles of dirty snow to a Wiccan shop in the west of the 20s, at the Ninth Avenue. At the back, from a rotating pile of hooks, I hit a dusty herbs over another. Goldenseal, black cohosh, tansy... the list continued. The guy at the counter, a skeletal figure with a goat and a black hair shock, looked at my options and avoided his eyes. The tea I made, according to Nancy's instructions, tasted like hot mud. I had to drink it three times a day with an empty stomach. It was an infallible recipe, Nancy said, although a woman she knew took three more months to cheat. But he wasn't alive in it, Nancy said. I haven't been alive for a while. I brought the herbs and an immersion coil with me at my Christmas visit house, where everyone comforted me in my divorce and wanted to know about my new exciting life in Manhattan. I avoided the nuts and the egg punch and sneaked into my room to make and drink the tea. I was drinking death, I told myself. I felt death was going through my stomach, in my veins. Nobody knew what these herbs were doing. If I was killed as well as the fetus I was carrying, maybe that was the consequence I needed to face. Who was stupid enough to get pregnant twice in so many years? Who was too stupid and obstinate to take advantage of the abortion services that we all worked so hard to make legal and safe? Me, that was who. In my diary I wrote letters to every member of my family, to my close friends, to my ex-husband and to my current lover. This beer could kill me, I confessed in the letters, and I was sorry, and I loved them. A week after I returned to New York, I stopped drinking tea, according to Nancy's instructions. Two weeks later, I came to my senses. I made the appointment at the clinic. The doctor tightened my hand after the procedure was complete. Now it's O.K., he said. It's over. It's not over, of course. At the bottom of my throat, all these years later, I still taste that tea. His remembered tang is the bitter end of repentance, the lower side of the choice. As the creature of the Stephen Crane desert, I find myself savoring, because it is bitter, and because it is my heart. Advertisement Site IndexSite Information Navigation

Blue Cohosh: A word of caution Related Articles Blue Cohosh: A word of caution October 1999; Volume 1: 81-83 By Beth Irikura and Edward J. Kennelly, PhD The blue cohosh (caulophyllum thalictroides [l.] michx., [Berberidaceae family]) has a long history of use, especially for gynecological conditions. The roots and rhizomes of blue cohosh were reportedly used by Native Americans for inducing labour or abortion. Other uses include colic, epilepsy, rheumatism, hips and sore throat. 1 In North America, blue cohosh is available in various forms, including herbal mixtures targeted specifically at women. The grass is oxytociccal and has a reputation of abortifacient. Because of the questionable activity and security of some of its constituents, the blue cohosh must be used only with extreme caution. Many herbalists advise not to use it in early pregnancies and it is better to avoid it even in late pregnancies. Background Background Blue cohosh is often used in combination with black cohosh (Cimicifuga racemosa), a plant not related to similar applications, but different chemical components and an undetermined action mechanism. 2 Both herbs received the name Algonquin cohosh, which means rough, for the appearance of their roots. From 1882 to 1905, the blue cohosh was listed (for labor induction) at the United States Pharmacopea. Although a casual survey of contemporary herbs reveals a variety of uses, the most common application is still to induce work. A recent study of 172 certified nurses-midwives (CNMs) found that, of the 90 CNMs who prescribed or encouraged the use of herbal work-stimulating preparations, 64% used blue cohosh and 45% used black cohosh.3 21% of CNM reported complications when herbs were used. Associated with the use of blue and black cohosh were nausea, meconium-stained liquid and transient fetal tachycardia. Two long-known glucosides that have been present in the blue cohosh — cauloaponin and caulophyllosaponin — may be responsible for their reported oxitocic effects. Both saponins have vasoconstrictor activity, uterin stimulant activity and cardiotoxic effects. 4 Suspects Teratogens Suspects Teratogens A recent study suggests that blue cohosh contains potential teratogen compounds.5 Several potentially dangerous alkaloids were identified in extracts of blue cohosh: anagirine, N-methylchocin and taspine. Anagyrine is a teratogen known in grazing animals. When the pregnant livestock consumes lupine (species lupina), which contains high levels of anagirine, the breed usually manifests torcid calf disease, a syndrome that includes slanted or twisted limbs, permanently rigid joints, spinal curvature and cleft palate occasionally.6 In the 1970s, statistical correlation and controlled feeding experiments established that anagirine caused deformations. 7 Anagyrine is one of the main alkaloid components of blue cohosh. It has been reported in blue cohosh rhizomes at a concentration of 290 ppm.8 Effects on humans have not been proven, but the gravity and frequency of teratogenicity in range animals are reasons for warning. Anagirine may have very different effects on humans and ruminants due to differences in intestinal flora; anagirine is thought to require metabolism by the Romanian microflora to expose teratogen effects. A reported case suggests a link between the maternal consumption of goat milk containing anagirine and birth defects in which the baby showed vascular anomaly, skeletal dysplasia and red blood cell malformation.9 FDA researchers have suggested that women may be wise to avoid ingesting anagirin at any level, until more information is made about their human activity. 8 A recent study using the cultures of rat embryos (REC) indicated that anagirine had teratogen potential only at the highest levels tested, when general morphogenesis was also affected.5 REC is an in vitro method to detect changes in the development of an embryo during the 45-hour crop period. Teratogenicity is determined by the presence of malformations that cannot be explained by a general and non-specific inhibition of growth and morphogenesis. The presence or absence of malformations is assessed separately from the determination of the state of development. The REC can identify possible neurotoxic effects. Relative inactivity of anagirine at lower concentrations can be explained by the fact that the REC cannot detect musculoskeletal deformations. N-Methylchocin is a second potentially dangerous compound identified from blue cohosh. In cultivated rat embryos, blue cohosh N-methylchocitisin caused major malformations.5 At a concentration of 20 ppm, the effects included an earlier open neural tube, poor or absent eye development, and twisted tail. The highest concentrations of methylcythein inhibited general growth and morphogenesis, as well as similar malformations. In a separate study, methylcitisine N was also found to stimulate the nodes of heart vapor in frogs, paralyze the nodes of the heart vague in dogs, and produce hyperglycemia in rabbits. 10 Some of the actions of N-methylchocin are similar to nicotine. 10 Exposure to nicotine through smoking in pregnant women has been related to poor fetal growth, neuronal dysmorphology, fetal death and cognitive deficits in surviving upbringing. 11 This epidemiological evidence has been supported by in vitro and in vivo studies. N-Methylchocin in dietary supplements containing blue cohosh has been measured in concentrations ranging from 5-850 ppm.8 No research has been carried out on the pharmacokinetics or pharmacodynamics of the blue cohosh or its constituents; therefore, the clinical significance of the experiments mentioned above remains unknown. However, women who anticipate a pregnancy may want to avoid using dietary supplements containing blue cohosh until they understand the possible in vivo teratogen effects of this botanist. Taspine, another constitutive of caulophyllum, is only in low yield (0.00013% per weight) in blue rhinoceros cohosh.5 Taspine is cytotoxic at concentrations of 0.5 ppm.12 In embryonic cultures of rats, tasine was lethal in concentrations of 5 ppm.5 Tasine is related to other phenomenal alkaloids such as morphine, heroin and codicena, which are highly cytotoxic and presumed human teratogens. 13 Adverse fetal effects in humans Adverse fetal effects in humans There are several reported cases of adverse results related to the ingestion of blue cohosh. In the best documented case, the baby suffered deep congestive heart failure associated with acute anterolateral myocardial infarction by maternal ingestion of three times the recommended dose for three to four weeks before the partition. 14 The baby required mechanical ventilation 20 minutes after partition, and showed bad perfusion, mitral regurgitation murmur, cardiomegaly and pulmonary edema. Hepatomegaly and abnormal liver function, consistent with cardigen shock, gradually dissolves. The baby was initially hospitalized for 31 days and remained in the respirator for three weeks. Two years later the child was normally developed, but still required treatment of digoxin for persistent cardiomegaly and reduced left ventricular function. Researchers ruled out other possible causes of myocardial infarction, such as anomalies in the coronary artery. In another case, a midwife advised the mother to take a mixture that included blue cohosh and black cohosh to induce the job. 15 Researchers in this case suggest that myocardial toxicity (known as associated with caulosaponin and caulofilloaponin found in blue cohosh) could explain the severe hypoxic-ischemic symptoms observed in the newborn. 16 This work has been criticized for not providing specific information on dosage, frequency or time of use, and type of preparation of herbs ingested by the patient. 17 In addition, two cases related to consumption of blue cohosh are listed in the database of the FDA's adverse event monitoring system. 18 The first involved a stroke in a baby, after the ingestion of blue cohosh with grain alcohol. In the second case, the baby developed aplastic anemia after maternal exposure to blue cohosh and unspecified products. Conclusion Conclusion Several adverse results can be explained by fetal exposure to blue cohosh. In addition, recent work indicates that the components of blue cohosh cause teratogenic effects in cultures embryos of rats. Future studies can correlate additional epidemiological evidence with animal studies. Practitioners are advised that blue cohosh is a powerful pharmacological agent and can be contraindicated during pregnancy. Women of childbearing age are urged to consult health professionals with knowledge before using this herb.
