A research study suggests Essiac may stimulate growth of breast cancer cells. Essiac tea is one of the most common herbal treatments that patients employ in their self-treatment of cancer. Some weeks it seems that everyone is drinking it, dewey flor and cancer. Essiac has an interesting history, dewey flor and cancer. The full story of how Canadian dewey flor and cancer Rene Caisse came upon an Ojibwa herbal formula for treating cancer and then went on to save untold numbers of lives is detailed at great length on the half million or so websites devoted to selling Essiac.
Dewey flor and cancer the widespread use of Essiac and the many health food stores and websites that promote and sell it, the extreme paucity of published research on Essiac is surprising. Most of these hits turn out to be about alternative medicines used by cancer patients and simply mention Essiac in passing. Actual research on Essiac is almost nonexistent. In contrast, searching for information on ginger yields papers, 73 of which are about cancer.
Dewey flor and cancer papers have been published on Essiac in the last few years and are worth noting. One in particular is important because it suggests that using Essiac may be dangerous for patients with breast cancer. Two papers are about Essiac and prostate cancer and are positive. In Augustthe Journal of Alternative and Complementary Medicine published a test tube study that showed that Essiac might inhibit prostate tumor cell growth. They were able to demonstrate some anti-cancer effect from these products but only at very strong concentrations.
In Novemberthe same Center for Complementary Medicine Research published data comparing the antioxidant and anti-inflammatory effect of Essiac and Flor-Essence. This dewey flor and cancer not something we are eager to see. High levels of iNOS are associated with a worse prognosis for cervical cancer [vi] and increased risk of getting breast cancer from radiation treatment. In fact, high levels of iNOS increases the risk of getting breast cancer from radiation exposure by seven fold.
When looking at herbal extracts it is nice if they work in vitro. That is, you add a little of the herbal extract into a test tube filled with cancer cells and some or all of the cancer cells drop dead. Not all herbs that are useful for cancer patients do this. Some herbs may act as immune stimulants, rather than killing the cancer cells directly, they get the immune system to kill the dewey flor and cancer. Mushroom polysaccharides appear to work like this, dewey flor and cancer.
Digitalis, once used to treat congestive heart disease, decreases breast cancer recurrence by unknown mechanisms. Testing these herbs in vitro, in a test tube, will not tell us if they work; they only work in vivo, that is, in a living animal, dewey flor and cancer.
Despite the absence of positive Essiac results in vitro, practitioners assumed in vivo tests would yield better results. More than disappointing are the data published in August issue of Breast Cancer Research and Treatment, that say Essiac stimulates growth of breast cancer cells.
Knowing how many cancer patients use Essiac, it is of great concern to read: Essiac may provide some benefit to patients with prostate cancer but there is better research encouraging one to eat ketchup. For other types of cancer, there is little encouraging research and for breast cancer, these results argue against using Essiac. To describe the prevalence, clinical characteristics, and pattern of use of complementary and alternative medicine CAM in patients enrolled onto phase I trials.
Questionnaires were administered to patients with advanced malignancies enrolled onto phase I chemotherapy trials at the Mayo Clinic Comprehensive Cancer Center RochesterMN.
CAM was classified into two modalities, pharmacologic and nonpharmacologic. Clinical and demographic data, including age, sex, and prior cancer treatment, were subsequently obtained from patient charts and examined for any correlation with CAM use, dewey flor and cancer, using chi2 analysis. One hundred two survey forms were returned. Vitamin and mineral preparations constituted Intake was highest for vitamins E Prayer and spiritual practices were the most commonly used nonpharmacologic CAMaccounting for Both CAM modalities were used more frequently by women To assess the ability of Essiac tea extracts Essiac Canada International, dewey flor and cancer, OttawaCanada to modulate cancer cell proliferation and immune responsiveness.
A noncancerous transformed cell line was compared to a cancerous cell line and spleen cells that had been isolated dewey flor and cancer mice to examine proliferation responses mediated by the addition of an Essiac preparation. We found in vitro evidence of decreased proliferation of both noncancerous transformed CHO and cancerous prostate cell line LNCaP when Essiac was present in the culture media.
The percent inhibition of the LNCaP cells was higher than the percent inhibition of the CHO cells suggesting that Essiac may have a more selective effect on cancer cells than transformed cells, dewey flor and cancer. In addition, the effects of Essiac were examined in an immune T-lymphocyte proliferation assay.
At low doses of Essiac, augmentation of proliferation of these T cells was demonstrated, but at higher doses Essiac was inhibitory to T-cell proliferation.
Essiac preparations may be able to inhibit tumor cell growth while enhancing immune response to antigenic stimulation. This may be especially valuable in immune-suppressed individuals. Essiac is a popular complementary and alternative medicine CAM that is utilized by many cancer patients in North America. Much anecdotal reporting exists about its cancer-fighting qualities, but so far no clinical trials have been preformed to validate those claims. We describe here the case of a year-old man whose hormone-refractory prostate cancer responded well to Essiac tea.
In vitro studies on the antiproliferative and differentiation inducing activities of these teas were performed. ES and FE showed negligible antiproliferative activity on Jurkat leukemia dewey flor and cancer. Our data show that both ES and FE herbal teas demonstrated antiproliferative and differentiation inducing properties in vitro only at high concentrations.
Further research is needed to elucidate the in vivo activities. The antioxidant and anti-inflammatory properties of these two herbal teas were assessed in this study, dewey flor and cancer. Further research is needed to investigate the differential activities of these two herbal teas in stimulating pro-inflammatory mediators release by RAW Epub Dewey flor and cancer To investigate the expression of inducible nitric oxide synthase iNOS and cyclooxygenase-2 COX-2 in cervical cancer dewey flor and cancer their association with clinical outcome in patients treated with radical radiotherapy.
One hundred sixty-seven consecutive patients with FIGO Stages IB-IVA squamous cell cervical cancer underwent radical radiotherapy, dewey flor and cancer, including external-beam radiotherapy or high-dose-rate brachytherapy, or both, between and Immunohistochemical studies of their formalin-fixed, paraffin-embedded tissues were performed.
Univariate and multivariate analyses were performed to identify and evaluate the effects of the factors affecting patient survival.
Overexpression of iNOS or COX-2 or both was associated with decreased survival and a greater propensity to metastasize in cervical cancer patients treated with radiotherapy. Coexpression of iNOS and COX-2 may represent a useful biologic marker in patients receiving radical radiotherapy for cervical cancer.
Epub Dec This study evaluated whether nitric oxide NO derived from nitric oxide synthase NOS induced by radiation is associated with tumorigenesis in the mammary glands. When rats were exposed to whole-body irradiation with dewey flor and cancer 1. The tumor incidence declined to On treatment with PBN or W, dewey flor and cancer, no adenocarcinoma developed.
Many of the mammary tumors dewey flor and cancer developed in the irradiated rats were positive for the estrogen receptor ER. These results indicate that iNOS-derived NO may participate in the formation of estrogen-dependent mammary adenocarcinomas following radiation. An additional injection of chemicals followed twice at 8 and 24h after the irradiation in the same manner.
Both control and treated rats were then implanted with diethylstilbestrol pellets as a tumor promoter. The mammary tumor incidence in the experimental group was significantly reduced to one-fourth of that in the irradiated-alone group as the control. On the other hand, when mother rats took drinking water containing 0. This report is the first to show that the NO derived from iNOS is an important radical for radiation-induced initiation of tumorigenesis of mammary glands in rats.
Essiac is a herbal compound that has been in common use with cancer patients in North America for over 80 years.
Despite its dr fuhrman and diabetes widespread use, there are no peer-reviewed published reports of in vivo studies regarding the use of this compound.
Essiac was administered orally to test animals prior to all experiments. Standard assays to test protection from ethanol-induced gastric ulceration and carbon tetrachloride-induced hepatic injury were performed on Wistar rats. Essiac demonstrated a modest gastric protective effect via amitriptyline and cat of ethanol-induced gastric ulceration.
However, Essiac did not demonstrate significant hepatoprotective, hypoglycemic or immunomodulatory properties. Essiac, administered in established in vivo experimental models, dewey flor and cancer, did not significantly demonstrate its purported physiological modifying effects.
Epub Mar People diagnosed with cancer often self-administer complementary and alternative medicines CAMs to conception and vitamin b their conventional treatments, improve health, or prevent recurrence.
Flor-Essence and Essiac Herbal Tonics are commercially available complex mixtures of herbal extracts sold as dietary supplements and used by cancer patients based on anecdotal evidence that they can treat or prevent disease. In this study, we evaluated Flor-Essence and Essiac for their effects on the growth of human tumor cells in culture. Estrogen receptor ER dependent activation of a luciferase reporter construct was tested in MCF-7 cells.
Exposure to the tonics also produced a dose-dependent increase in ER dependent luciferase activity in MCF-7 cells. Flor-Essence and Essiac Herbal Tonics can stimulate the growth of human breast cancer cells through ER mediated as well as ER independent mechanisms of action.
