RESUMO

Doctor, Do You Know Red Yeast Rice? Abstract. We present cases of patients with high total cholesterol who wanted to use an alternative therapy for lowering cholesterol. An improvement in the lipid profile was found in all patients, and all tolerated the product made from red rice yeast very well. No side effects were observed. The patients who take red fermented rice consciously choose an alternative agent in the field of phytotherapy because they already have to take several conventional medicines and are no longer willing to use an additional drug of this kind. Another reason is that they no longer want to put up with the side effects they suffered from when using a common lipid-lowering drug.

RESUMO

An earlier prospective, randomised, placebo-controlled clinical trial had suggested that Bryophyllum pinnatum might have potential in the treatment of overactive bladder. Here we investigated the effects of B. pinnatum leaf press juice, fractions enriched in flavonoids and bufadienolides, and a flavonoid aglycon mixture and individual aglycons on detrusor contractility as a major target in overactive bladder treatment. The strength of the detrusor contractions was investigated using porcine muscle strips stimulated with KCl. B. pinnatum leaf press juice increased the contraction force of muscle strips. Treatment with the flavonoid-enriched fraction had almost no effect on contractility, while the bufadienolide-enriched fraction and flavonoid aglycons led to a concentration-dependent lowering of the contraction force. The data indicate that several components of B. pinnatum leaf press juice may contribute to the inhibitory effect on detrusor contractility, which in turn provides support to overactive bladder treatment with B. pinnatum.

RESUMO

Bryophyllum pinnatum (syn. Kalanchoe pinnata) is a succulent perennial plant native to Madagascar that was introduced in anthroposophic medicine in the early 20th century. In recent years, we conducted a large collaborative project to provide reliable data on the chemical composition, pharmacological properties, and clinical efficacy of Bryophyllum. Here, we comprehensively review the phytochemistry, as well as the pharmacological and clinical data. As to the pharmacology, special emphasis is given to properties related to the use in anthroposophic medicine as a treatment for "hyperactivity diseases", such as preterm labor, restlessness, and sleep disorders. Studies suggesting that B. pinnatum may become a new treatment option for overactive bladder syndrome are also reviewed. Tolerability is addressed, and toxicological data are discussed in conjunction with the presence of potentially toxic bufadienolides in Bryophyllum species. The few data available on two related species with medicinal uses, Bryophyllum daigremontianum and Bryophyllum delagoense, have also been included. Taken together, current data support the use of B. pinnatum for the mentioned indications, but further studies are needed to fully understand the modes of action, and to identify the pharmacologically active constituents.

RESUMO

BACKGROUND: Bryophyllum pinnatum has been introduced in anthroposophic medicine in Europe and is nowadays also widely used in conventional medicine. The aim of this study was to assess the prescriptions in the field of gynaecology and obstetrics in Switzerland and to document potential effects and possible adverse events of B. pinnatum. PATIENTS AND METHODS: Private practices and clinics for obstetrics and gynaecology were asked to document each prescription of B. pinnatum for their female patients during 31 months with an online questionnaire. RESULTS: At the University Hospital Zurich, at the Cantonal Hospital Winterthur as well as at 2 private practices, a total of 174 women and 208 prescriptions of B. pinnatum were recorded (several prescriptions per patient were possible). Most of the patients were pregnant (87%). B. pinnatum was prescribed as a tocolytic agent to 83% of all patients and to 95% of all pregnant patients and showed a good or a very good effectiveness. Further, 14% of the patients received B. pinnatum for sedation against their restlessness during the day and 5% for sedation against sleep problems. A decrease of the restlessness was achieved for these 2 indications. 13% of the patients suffered from a hyperactive bladder and in two-thirds of them the effectiveness of the treatment with B. pinnatum was classified as very good. In 92% of the cases, Bryophyllum 50% chewable tablets were prescribed. CONCLUSIONS: In conventional gynaecology and obstetrics, B. pinnatum is predominantly prescribed for pregnant women in case of prematurel abour, against restlessness and for hyperactive bladder. B. pinnatum showed a good effectiveness with a high benefit in the treatment of hyperactivity-associated health problems.

RESUMO

A quantitative assay for determination of the main bufadienolides bersaldegenin-1-acetate (1), bersaldegenin-3-acetate (2), bryophyllin A (3), and bersaldegenin-1,3,5-orthoacetate (4) in Bryophyllum pinnatum leaves and manufactured products was developed and validated. The assay involved extraction by pressurised liquid extraction, followed by quantification by ultrahigh performance liquid chromatography-tandem mass spectroscopy. The ultrahigh performance liquid chromatography-tandem mass spectroscopy method was applied to various batches of leaves harvested on several dates from plants grown at two locations (Brazil and Germany). In addition, press juices prepared from plants cultivated in Germany and Brazil were analysed. The total bufadienolide content ranged from 16.28 to 40.50 mg/100 g dry weight in leaves from plants grown in Brazil. The total content of these four bufadienolides was significantly lower in plants cultivated in Germany (3.78-12.49 mg/100 g dry weight, resp.). The total amounts of bufadienolides were 0.091-0.163 mg/100 mL and 0.89-1.16 mg/100 mL in press juices obtained from plants cultivated in Germany and Brazil, respectively. When analysing single leaves from individual plants, the content of bufadienolides was markedly higher in young leaves. For comparative purposes, the content of these bufadienolides was also determined in Bryophyllum daigremontianum and Bryophyllum tubiflorum. Bersaldegenin-1,3,5-orthoacetate (4) was predominant in the leaves of B. daigremontianum and in the stems of B. tubiflorum, while the leaves of B. tubiflorum contained very low amounts of 1-4.

RESUMO

HYPOTHESIS: Cancer patients frequently suffer from poor sleep quality. Bryophyllum pinnatum is a herbal medication used in anthroposophic medicine, which has been shown to be associated with improvements in sleep quality during pregnancy with only few and minor or moderate side-effects reported. In this study, the sleep quality of cancer patients during treatment with B pinnatum was investigated. STUDY DESIGN: In this prospective, observational study, cancer patients suffering from sleep problems were treated with B pinnatum (350 mg tablets, corresponding to 50% of leaf pressed juice [Weleda AG, Arlesheim, Switzerland], dosage at physician's consideration, but most frequently 2 tablets with evening meal and 2 before going to bed). METHODS: Sleep quality (Pittsburgh Sleep Quality Index [PSQI]), daily sleepiness (Epworth Sleeping Scale [ESS]), and fatigue (Fatigue Severity Scale [FSS]) were assessed at the beginning of the treatment and after 3 weeks. Possible adverse drug reactions perceived by the patients during the treatment were recorded. From the 28 recruited patients, 20 completed both questionnaires and were considered in the present analysis. Data are expressed as mean ± standard deviation. RESULTS: Patients were 61 ± 10.4 years old and the majority were female (17 out of 20). During treatment with B pinnatum, the PSQI decreased from 12.2 ± 3.62 to 9.1 ± 3.61 (P < .01), and ESS changed from 8.4 ± 3.18 to 7.1 ± 3.98 (P < .05). There was no change in FSS. The treatment was well tolerated by the majority of patients, with only 6 patients reporting discomfort that might have been caused by B pinnatum (fatigue n = 3, dry throat n = 1, agitation n = 1, difficult digestion n = 1). No serious adverse drug reactions were detected. CONCLUSION: B pinnatum may be a suitable treatment for sleep problems of cancer patients. Controlled, randomized clinical trials of the use of B pinnatum in sleep disorders are urgently needed.

RESUMO

Bryophyllum pinnatum is a succulent perennial plant native to Madagascar which is used in anthroposophical medicine to treat psychiatric disorders and as a tocolytic agent to prevent premature labour. We performed a metabolite profiling study in order to obtain a comprehensive picture of the constituents in B. pinnatum leaves and to identify chromatographic markers for quality control and safety assessment of medicinal preparations. Preliminary HPLC-PDA-ESIMS analyses revealed that flavonoid glycosides were the main UV-absorbing constituents in the MeOH extract of B. pinnatum. Two phenolic glucosides, syringic acid ß-D-glucopyranosyl ester (1) and 4'-O-ß-D-glucopyranosyl-cis-p-coumaric acid (2), as well as nine flavonoids (3-11) including kaempferol, quercetin, myricetin, acacetin, and diosmetin glycosides were unambiguously identified by 1H and 2D NMR analysis after isolation from a MeOH extract. The flavonol glycosides quercetin 3-O-α-L-arabinopyranosyl-(1 → 2)-α-L-rhamnopyranoside 7-O-ß-D-glucopyranoside (3) and myricetin 3-O-α-L-arabinopyranosyl-(1 → 2)-α-L-rhamnopyranoside (4) were new natural products. With the aid of HPLC-PDA-APCIMS and authentic references isolated from the related species B. daigremontianum, the presence of four bufadienolides, bersaldegenin-1-acetate (12), bryophyllin A (13), bersaldegenin-3-acetate (14), and bersaldegenin-1,3,5-orthoacetate (15) was detected in B. pinnatum.
