“…Over the past decade, there has been a dramatic increase in the demand for medicinal plants for use in traditional medicine (TM) and contemporary and alternative medicine (CAM) in both developing and developed countries (Lee et al 2008). In China, TM accounts for about 40% of all health care delivered (WHO 2002) and, in Amazonia, medicinal plants serve as the main form of healthcare for a majority of the populace (Shanley and Luz 2003).…”

This study considered traditional ethno-medicinal practices of rural people of Feni district, Bangladesh, focusing on their utilization of medicinal plants and associated indigenous knowledge. Ninety households were interviewed using a semistructured questionnaire. Plant resources are used to treat 26 different ailments ranging from simple cuts to diabetes. In total, 46 medicinal plants are as used, of which a third are trees. Homesteads are the primary source and few medicinal plants are cultivated. Aboveground plant parts are most used, particularly leaves. The diverse patterns of use of different medicinal plant parts shows the considerable indigenous knowledge of rural people and is generally widely available.

“…Because these areas take up a large chunk of useable land from the indigenous people, denying them ownership rights, and resources exploitation which they had hitherto enjoyed in the past (Dikobe 1995, Mbaiwa, 2005, many local communities in protected areas resists such land "usurpation." This antagonism to protected areas by the local people can be traced to several identified factors (Chambers, 1986;Dikobe, 1995;Ferraro, 2002;Gillingham & Lee, 2003;Shanley and Luz, 2003;Wittemyer et al, 2008;Mundia & Murayama 2009). The reasons may vary from one protected area to another (Fig 1).…”

“…When not harvested properly, the habitat is damaged, (Shanley & Luz, 2003), leading to decline or loss of low density plant species (Cunningham, 1993). Sometimes the level of poverty among the local communities is so high that one can not contemplate the prospect of getting treatment without these herbs, given that most locals can not afford the medical bills in orthodox medical facilities even if they were provided in the area.…”

“…It rather continues to impact negatively on the habitat of the protected area. The temptation also to earn income as a result of the booming traditional medicine market has also encouraged the illegal exploitation of exotic plant species (Shanley & Luz, 2003) and the poaching of wildlife of medicinal importance in many countries. However, this factor is rather extrinsic, as it does not relate to the basic need of the locals.…”

This review identifies some intrinsic and extrinsic factors that tend to drive the destruction of habitat, game poaching and unsustainable utilization of plants products by communities surrounding many protected areas around the world, leading to wildlife and plant species decline. Intrinsic factors are basic needs of the locals; those needs are intricately tied to land and poverty. Other factors also exist such as increased population, trade in endangered species and deforestation that are extrinsic and not the immediate needs of the local communities in protected areas but nevertheless contribute in forcing the communities to abandon the path to sustainable utilization of natural resources in protected areas leading to habitat fragmentation, depletion and loss of wildlife and plants species

“…However, the intense mixture of cultures (Native, African and European) during the last several centuries has led to a progressive substitution from native medicinal plants to other species from elsewhere in Latin America (Dean, 1996). The accelerating destruction of Brazil's botanically rich native ecosystems has also contributed to a gradual loss of knowledge about native plants used in traditional medicine, including those found in areas of the Atlantic Forest and the Amazon where accelerated occupation takes place (Begossi et al, 2002;Brandão et al, 2004;Shanley & Luz, 2003;Shanley & Rosa, 2005).…”

RESUMO: "Influencia do método de preparação na baixa eficácia de produtos fitoterápicos: o exemplo do João da Costa e Associações ® ." Plantas medicinais nativas do Brasil foram usadas por décadas pelas indústrias farmacêuticas nacionais para criar seus produtos. Neste estudo, foi investigado o produto João da Costa e Associações ® (JCA) comercializado por mais de trinta anos para o tratamento de dismenorréia e outros problemas relacionados à saúde da mulher. JCA é preparado pela decocção de Himatanthus lancifolius (Muell. Arg.) Woodson (Apocynaceae), Chondodendron platyphyllum Miers (Menispermaceae), Gossypium herbaceum L. (Malvaceae), Rosmarinus officinalis L. (Lamiaceae) e Echites peltata (Apocynaceae), seguido de adição de açúcar. A eficácia de JCA foi verificada por meio da avaliação da atividade antinociceptiva. Já a composição química foi determinada por analises em HPLC/ DAD. Uma fraca inibição da segunda fase da nocicepção foi observada no teste da formalina, indicando uma ação semelhante aos antiinflamatórios esteroidais e não esteroidais. Apesar de ser preparado pela decocção de cinco plantas, a análise no HPLC apresentou somente dois picos, e nenhum deles correspondeu aos componentes observados nos extratos etanólicos preparados com as mesmas plantas. Os resultados sugerem que o método de preparação de JCA promove a perda dos componentes químicos das plantas e interfere consideravelmente na eficácia do produto. Unitermos: espécies nativas, produto comercial, Himatanthus lancifolius, Chondodendron platyphyllum, Gossypium herbaceum, Echites peltata.ABSTRACT: Native medicinal plants have been used for decades by Brazilian pharmaceutical companies to create commercial products. In this study, we have investigated the herb-combined product João da Costa e Associações ® (JCA) commercialized for thirty years to treat dysmenorrhoea. JCA is prepared by decoction of Himatanthus lancifolius (Muell. Arg.) Woodson (Apocynaceae), Chondodendron platyphyllum Miers (Menispermaceae), Gossypium herbaceum L. (Malvaceae), Rosmarinus officinalis L. (Lamiaceae) and Echites peltata (Apocynaceae), followed by addition of sugar. The efficacy of JCA was verified by antinociceptive studies. The chemical composition was determined by fingerprint analysis in HPLC/ DAD. A weak inhibition of the second phase of the nociceptive effect induced by formalin indicated an activity similar to those steroids and notsteroids anti-inflammatories. Despite being prepared by decoction of five plants, the fingerprint analysis showed only two peaks. None of them corresponds to the chemical compounds observed in ethanol extracts prepared with the same plant material. We argue that the methods of preparation of the formulas should be considered in studies of multi-herbs products, since they can be the responsible for inefficacy or low activity of such products.
