Factors influencing self-diagnosis and treatment of perceived helminthic infection in a rural Guatemalan community

Singab A. Botanicals against some important nematodal diseases: Ascariasis and hookworm infections

Ascariasis and intestinal parasitic nematodes are the leading cause of mass mortality infecting many people across the globe. In light of the various deleterious side effects of modern chemical-based allopathic drugs, our preferences have currently shifted towards the use of traditional plant-based drugs or botanicals for treating diseases. The defensive propensities in the botanicals against parasites have probably evolved during their co-habitation with parasites, humans and plants in nature and hence their combative interference in one another's defensive mechanisms has occurred naturally ultimately being very effective in treating diseases. This article broadly outlines the utility of plant-based compounds or botanicals prepared from various medicinal herbs that have the potential to be developed as effective therapies against the important parasites causing ascariasis and intestinal hookworm infections leading to ascariasis & infections and thereby human mortality, wherein allopathic treatments are less effective and causes enormous side-effects.

The antibacterial and antifungal activity of essential oils extracted from Guatemalan medicinal plants

CONTEXT

Essential oils are prevalent in many medicinal plants used for oral hygiene and treatment of diseases.

OBJECTIVE

Medicinal plant species were extracted to determine the essential oil content. Those producing sufficient oil were screened for activity against Staphylococcus aureus, Escherichia coli, Streptococcus mutans, Lactobacillus acidophilus, and Candida albicans.

MATERIALS AND METHODS

Plant samples were collected, frozen, and essential oils were extracted by steam distillation. Minimum inhibitory concentrations (MIC) were determined using a tube dilution assay for those species yielding sufficient oil.

RESULTS

Fifty-nine of the 141 plant species produced sufficient oil for collection and 12 species not previously reported to produce essential oils were identified. Essential oil extracts from 32 species exhibited activity against one or more microbes. Oils from eight species were highly inhibitory to S. mutans, four species were highly inhibitory to C. albicans, and 19 species yielded MIC values less than the reference drugs.

DISCUSSION

RESULTS suggest that 11 species were highly inhibitory to the microbes tested and merit further investigation. Oils from Cinnamomum zeylanicum Blume (Lauraceae), Citrus aurantiifolia (Christm.) Swingle (Rutaceae), Lippia graveolens Kunth (Verbenaceae), and Origanum vulgare L. (Lamiaceae) yielded highly significant or moderate activity against all microbes and have potential as antimicrobial agents.

CONCLUSION

Teas prepared by decoction or infusion are known methods for extracting essential oils. Oils from 11 species were highly active against the microbes tested and merit investigation as to their potential for addressing health-related issues and in oral hygiene.

Ethnophysiology and herbal treatments of intestinal worms in Dominica, West Indies

In rural Dominican ethnophysiology worms reside in a human organ called the 'worm bag'. Unchecked, worms can cause illness by growing in size and number, spreading out of the worm bag and into other organs. In this study of 'bush medicine', we use a measure of cognitive salience in free-listing tasks, which reveals five plants commonly used to treat intestinal worms. These were Ambrosia hispida (Asteraceae), Aristolochia trilobata (Aristlochiaceae), Chenopodium ambrosioides (Chenopodiaceae), Portulaca oleracea (Portulacaceae), and Artemisia absinthium (Asteraceae). Bioactive compounds appear to be present in all of these plants. The cognitive salience of these plant remedies coupled with evidence of biochemical properties suggest that they provide efficacious treatments for controlling intestinal parasite loads.

Health seeking behaviour for child illness in rural Guatemala

Considerable efforts were made in Guatemala to cover rural areas with health centres, and health programmes have been launched to treat and prevent the most important childhood diseases. Despite this, the utilization rate of public health services has reportedly been low throughout the past two decades. How, and how effectively, do mothers resolve the health problems of their children? To gain better insight into health care behaviour, we conducted a health services utilization survey in two highland communities in the department of Sacatepequez in 1992-1993. We asked 324 mothers in two villages whether, and where, they had sought help the last time their children under 5 years of age had suffered from diarrhoea, fever, cough symptoms or worms. Mothers relied on home care in 63-83% of reported episodes and the use of health services-Western or traditional-was consistently low. Although Western health care was easily accessible, it was used in only 8-15% of cases. The only identifiable significant independent determinants of utilization were occupational status of the mother (RR = 1.5 if employed) and overall level of socioeconomic development of the community (RR = 1.7). Inquiry into treatments used revealed that except for worms, which were frequently treated with herbs (31%) or external remedies (20%) alone, modern pharmaceuticals predominated. Antibiotics were the remedy of choice against diarrhoea (63%), antipyretics in case of fever (83%) and cough syrups with expectorants or antitussives against cough (65%). One hundred and twenty-one of the children born after 1975 died; in only 64 cases (53%) was a Western health service consulted between onset of disease and death. No relation was found between attendance and socioeconomic characteristics of the parents, but a positive linear association between duration of the fatal illness episode and age of the child could be identified. Independent sources report a drop in infant mortality of 53 and 35% respectively in the two communities between 1977 and 1991. Our findings seem to indicate that this reduction was achieved despite under-utilization of Western health services.
