[Acceptance and use of medicinal plants in family medicine].

OBJECTIVE: To explore the degree of usage of therapeutic medical plants among the patients, physicians and health workers in a local Family Medical Care Unit of the Mexican Institute of Social Security (IMSS)). MATERIAL AND METHODS: A transversal descriptive study was performed. A questionnaire focusing on two variables was designed and validated. It was applied to 60 family physicians, a randomized sample of 130 health workers and another of 264 patients of the Family Mediccal Care Unit. Response percentage was 78%. RESULTS: The study found that 83% of family physicians accept the therapeutic use of herbal medicine; moreover, 75% use it as a therapeutic resource. Among health workers, acceptance and use was 100%, while in patients the level of acceptance was of 92% and of use it was 90%. Differences between groups are significant (p < 0.05). The more frequently used plants are Gordolobo (Gnaphalium sp.), Eucalyptus (Eucalyptus sp., probably E. globulus), spearmint (Mentha sp.), camomile (Matricaria chamomilla) and prickly pear cladodes (the vegetative parts of the prickly pear, Opuntia sp. Probably Opuntia ficus indica). CONCLUSIONS: This information agrees with previous reports about Mexico, however, in this case, data were gathered in urban areas where physicians have been trained in the biomedical paradigm of medicine.

Inhibition of non-haem iron absorption in man by polyphenolic-containing beverages.

The effects of different polyphenol-containing beverages on Fe absorption from a bread meal were estimated in adult human subjects from the erythrocyte incorporation of radio-Fe. The test beverages contained different polyphenol structures and were rich in either phenolic acids (chlorogenic acid in coffee), monomeric flavonoids (herb teas, camomile (Matricaria recutita L.), vervain (Verbena officinalis L.), lime flower (Tilia cordata Mill.), pennyroyal (Mentha pulegium L.) and peppermint (Mentha piperita L.), or complex polyphenol polymerization products (black tea and cocoa). All beverages were potent inhibitors of Fe absorption and reduced absorption in a dose-dependent fashion depending on the content of total polyphenols. Compared with a water control meal, beverages containing 20-50 mg total polyphenols/serving reduced Fe absorption from the bread meal by 50-70%, whereas beverages containing 100-400 mg total polyphenols/serving reduced Fe absorption by 60-90%. Inhibition by black tea was 79-94%, peppermint tea 84%, pennyroyal 73%, cocoa 71%, vervain 59%, lime flower 52% and camomile 47%. At an identical concentration of total polyphenols, black tea was more inhibitory than cocoa, and more inhibitory than herb teas camomile, vervain, lime flower and pennyroyal, but was of equal inhibition to peppermint tea. Adding milk to coffee and tea had little or no influence on their inhibitory nature. Our findings demonstrate that herb teas, as well as black tea, coffee and coca can be potent inhibitors of Fe absorption. This property should be considered when giving dietary advice in relation to Fe nutrition.

Microfungi on compositae in the Ruhr Basin.

Forty-three microfungi have been observed on thirty species of the Compositae occurring in several locations in the Ruhr Basin in North Rhine-Westphalia. Many fungi belong to the Ascomycetes (Erysiphales, Diaporthales, Dothideales, Leotiales and Pleosporales) and to the Deuteromycetes (Melanconiales, Moniliales and Sphaeropsidales). Other fungi wich were found in our investigation belong to the Basidiomycetes (Uredinales) and to the Oomycetes (Peronosporales). Some recorded microfungi have been discovered on new hosts in North Rhine-Westphalia and also in Germany for the first time. New for North Rhine-Westphalia are Ascochyta spec. Libert on Matricaria recutita L., Phoma exigua var. linicola (Naumov & Vassilevski) Maas on Tripleurospermum maritimum (L.) W. D. J. Koch, Phomopsis achillea (Sacc.)

Iberis amara L. and Iberogast--results of a systematic review concerning functional dyspepsia.

A systematic review referring to efficacy and tolerability of the herbal combination Iberogast (Iberis amara planta totalis, Chelidonii herba, Cardui mariae fructus, Melissae folium, Carvi fructus, Liquiritiae radix, Angelicae radix, Matricariae flos, Menthae piperitae folium) was performed in patients with functional dyspepsia. Three placebo-controlled trials and a reference-controlled trial showed a statistical significant and therapeutical relevant reduction of the gastrointestinal symptom-scores in 595 patients. The therapeutic efficacy was also found in one observational study (2267 patients). In accordance with the available evidence Iberogast seems to be an effective phytotherapeutic preparation to reduce the symptoms of dyspepsia yet, without central nervous side effects.

Allelopathic effects of weeds extracts against seed germination of some plants.

This study investigated the allelopathic effects of various weeds extracts on seed germination of 11 crop species. Most of the weed extracts tested had inhibitory effects on seed germination of common bean, tomato, pepper, squash, onion, barley, wheat, and corn at different application rates as compared with the 10% acetone control. Chickpea seed germination was inhibited by extracts of Solanum nigrum L., Chenopodium album L., and Matricaria chamomilla L. (10%, 20% and 22.5%, respectively) at the end of 21 day incubation period. However, Glycyrrhiza glabra L., Sorghum halepense (L.) Pers., and Reseda lutea L. extracts stimulated chickpea seed germination at the rates of 95%, 94%, and 93%, respectively, compared to control. It was concluded that some of the weed extracts tested in this study could be used as inhibitor while others could be used as stimulator for the crops.

Exposure to airborne microorganisms, dust and endotoxin during processing of peppermint and chamomile herbs on farms.

The aim of this study was to determine the levels of microorganisms, dust and endotoxin in the air during processing of peppermint (Mentha piperita) and chamomile (Matricaria recutita) by herb farmers, and to examine the species composition of airborne microflora. Air samples were collected on glass fibre filters by use of personal samplers on 13 farms owned by herb cultivating farmers, located in Lublin province (eastern Poland). The concentrations of total viable microorganisms (bacteria + fungi) in the farm air during processing of peppermint herb were large, within a range from 895.1-6,015.8 x 10(3) cfu/m(3) (median 1,055.3 x 10(3) cfu/m(3)). During processing of chamomile herb they were much lower and varied within a range from 0.88-295.6 x 10(3) cfu/m(3) (median 27.3 x 10(3) cfu/m(3)). Gram-negative bacteria distinctly prevailed during processing of peppermint leaves, forming 46.4-88.5 % of the total airborne microflora. During processing of chamomile herb, Gram-negative bacteria were dominant at 3 out of 6 sampling sites forming 54.7-75.3 % of total microflora, whereas at the remaining 3 sites the most common were fungi forming 46.2-99.9 % of the total count. The species Pantoea agglomerans (synonyms: Erwinia herbicola, Enterobacter agglomerans ), having strong allergenic and endotoxic properties, distinctly prevailed among Gram-negative isolates. Among fungi, the most common species was Alternaria alternata. The concentrations of airborne dust and endotoxin determined on the examined herb farms were large. The concentrations of airborne dust during peppermint and chamomile processing ranged from 86.7-958.9 mg/m(3), and from 1.1-499.2 mg/m(3), respectively (medians 552.3 mg/m(3) and 12.3 mg/m(3)). The concentrations of airborne endotoxin determined during peppermint and chamomile processing were within a wide range 1.53-208.33 microg/m(3) and 0.005-2604.19 microg/m(3) respectively (medians 57.3 microg/m(3) and 0.96 microg/m(3)). In conclusion, farmers cultivating peppermint are exposed during processing of this herb to large concentrations of airborne microorganisms, dust and endotoxin posing a risk of work-related respiratory disease. The exposure to bioaerosols during processing of chamomile is lower; nevertheless, peak values create a respiratory risk for exposed farmers.

Aphid parasitoid complex in potato in the context of IPM in Belgium.

Parasitic hymenoptera of potato aphids were collected and identified in 2000 and 2001 in 11 potato fields in Belgium. Nine Aphidiidae species, parasiting seven aphid species, were found: Aphidius ervi, Aphidius matricariae, Aphidius picipes, Binodoxys angelicae, Diaeretiella rapae, Praon abjectum, Praon gallicium, Praon volucre and Toxares deltiger. A. ervi and A. picipes were the dominant and sub-dominant species, with 54% and 28% of the primary parasite collected, respectively. Both species and T. deltiger were found on Aphis nasturti, Aulacorthum solani, Macrosiphum euphorbiae and Myzus persicae, the four most important aphid potato in Belgium. Parasitism rate of A. nasturtii and, to a lesser extent, M. euphorbiae was low compared to A. solani and M. persicae. Parasitism of A. solani was particularly high, with 63.5% in 2000 and 89.2% in 2001, and this species was the preferred host of several Aphidiid species. The abundance of alternative hosts as other crops pest aphids or non-pest aphids on wild plants in agroecosystems could explains the efficacy of these species. The biological control of A. nasturtii and M. euphorbiae by parasitic hymenoptera was poorer, and several studies need to be undertaken to find suitable parasitic hymenoptera species effective on these aphids and agro-environmental measures able to promote them.

[Evaluation of the activity on the mouse CNS of several plant extracts and a combination of them].

Some activities of seven vegetable extracts and an association of them given by oral route were tested on the C.N.S. of the mouse. Among these, Crataegus oxyacantha and, less clearly, Valeriana officinalis show some sedative activity, whereas the extract from Passiflora incarnata gives some anxiolytic effect. Matricaria chamomilla and Piscidia erythrina stand in an intermediate position between the previous ones. Hyoscyamus niger proved to be active in only one of the tests performed, whereas Atropa belladonna did not show any activity on the C.N.S. The association of the seven extracts seemed to act in a synergetic way, the resulting activity being sedative at high dosage and anxiolytic at low dosage.

Resistance of sheep to poisoning by The plant, Marticaria nigellifolia DC.

The plant, Matricaria nigellifolia, was dosed to 2 sheep to reinvestigate whether or not sheep are susceptible to pushing disease ("stootsiekte"). Each sheep received a total dose of 370 g/kg of the milled, dried plant from a batch that had caused pushing disease in cattle when given at doses as low as 10 g/kg. Neither of the sheep developed clinical disease over the trial period of 60 days, and necropsies revealed no macro- or microscopical lesions. Sheep are apparently resistant to pushing disease, which supports previous findings.

[Anti-inflammatory action of a group of plant extracts].

Use was made of Wistar albino rats in which an inflammation was induced via the simultaneous injection of caraginan and prostaglandin E1 in order to evaluate the antiinflammatory activity of 6 freeze dried plant extracts. It was found that with such model of inflammation the inflammatory effect of caraginan was strongly enhanced, which was accompanied by the rapid and prolific white blood cell extravasates. The freeze-dried extracts of St. John's-wort (Hypericum perforatum L.), potmarigold calendula (Calendula officinalis L.), camomile (Matricaria chamomilla L.) and plantain (Plantago lanceolata L. et Pl. major L.) were found to suppress both the inflammatory effect and the leukocyte infiltration. The extracts of symphytum (Symphytum officinale L.) and those of flax seed (Linum usitatissimum L.) did not inhibit the inflammation, however, they suppressed the leukocyte infiltration at the 3rd and 4th hour of the induced inflammation.

[Uterotonic action of extracts from a group of medicinal plants].

Water extracts (infusions) from a group of medicinal plants were studied in terms of their activity enhancing the uterine tonus in a series of experiments with a preparation of an isolated rabbit and guinea pig uterine horn. In a final extract concentration of 1 to 2 mg crude drug per 1 cm3 the plants ranked in the following descending order with regard to their tonus-raising effect on the uterus: camomile (Matricaria chamomilla L.), potmarigold calendula (Calendula officinalis L.) cockscomb (Celosia cristata L.), plantain (Plantago lanceolata L. et Plantago major L.), symphytum (Symphytum officinale L.), shepherdspurse (Capsella bursa pastoris L.), St.-John's wort (Hypericum perforatum L.). No effect showed the infusions of flax seeds (Linum usitatissimum L.) and bearberry leaves (Arctostaphylos uva-ursi L.). The combined preparation 'Antiinflamin', consisting of a pooled freeze-dried extract from three plants and chemotherapeutic agents produced a good enhancing effect, in the form of 'comprets' for intrauterine application at the rate of one compret per 2500 cm3.

Investigation of the effect of chamazulene on lipid peroxidation and free radical processes.

Oxygen toxicity and related free radical reactions are implicated in numerous pathophysiological conditions, like atherosclerosis, inflammation, gastric ulceration, neuronal degeneration, tumour promotion. The flowers of Matricaria chamomilla, Asteraceae, have been used therapeutically for conditions in which oxidative stress is supposed to be implicated. We considered interesting to investigate the effect of Chamazulene, the active substance of chamomile, on free radical processes. Membrane lipid peroxidation was induced by Fe2+/ascorbate and assessed as the 2-thiobarbituric acid reactive material. The hydroxyl radical scavenging activity was studied as the competition of Chamazulene with DMSO for HO. generated by Fe3+/ascorbate. Finally, the interaction of Chamazulene with the N-centered stable free radical DPPH was estimated photometrically (517 nm). It was found that Chamazulene inhibited lipid peroxidation in a concentration and time dependent manner presenting an IC50 of 18 microM after 45 min incubation. It could also inhibit the autoxidation of DMSO (33 mM) by 76% at 25 mM, and had a weak capacity to interact with DPPH. In conclusion, Chamazulene presents interesting properties concerning radical processes.

Validation of a capillary electrophoresis method for the quantitative determination of free and total apigenin in extracts of Chamomilla recutita.

A capillary electrophoretic method for the quantification of free and total apigenin in methanolic, ethanolic and glycolic extracts of Chamomilla recutita L. Rauschert (Asteraceae) is described. The method was validated for measurement of apigenin in the range 5.00-300 microg/mL (r2 = 0.993) and showed coefficients of intra-day (replicability) and inter-day (repeatability) variability of better than 2%. The limits of detection and quantification were 3.80 and 11.5 microg/mL, respectively, and the average recovery was 102.0 +/- 0.8% at three concentration levels of apigenin. Free and total apigenin contents in the extracts were, respectively, determined as 106 and 903 microg/g (methanolic extract), 77 and 817 microg/g (ethanolic extract) and 11.0 and 247 microg/g (glycolic extract).

Isolation, identification and stability of acylated derivatives of apigenin 7-O-glucoside from chamomile (Chamomilla recutita [L.] Rauschert).

The major flavonoids in the white florets of chamomile (Chamomilla recutita [L.] Rauschert) were rapidly purified using a combination of polyamide solid-phase extraction and preparative HPLC. From the combined LC/MS, LC/MS/MS, and NMR data the apigenin glucosides were identified as apigenin 7-O-glucoside (Ap-7-Glc), Ap-7-(6"-malonyl-Glc), Ap-7-(6"-acetyl-Glc), Ap-7-(6"-caffeoyl-Glc), Ap-7-(4"-acetyl-Glc), Ap-7-(4"-acetyl,6"-malonyl-Glc), and a partially characterised apigenin-7-(mono-acetyl/mono-malonylglucoside) isomer. Malonyl and caffeoyl derivatives of Ap-7-Glc have not previously been identified in chamomile. The two mono-acetyl/mono-malonyl flavonoids have not previously been reported in any plant species. These acylated glucosides are unstable and degrade to form acetylated compounds or Ap-7-Glc. The degradation products formed are dependent on the extraction and storage conditions, i.e. temperature, pH and solvent.
