Teaching about medicinal plants at school: Following in the footprints of Frei Veloso

Abstract

Brazil is home to the richest, most important and diverse flora in the world. This fact reveals the great plant potential of the country in the development of medicines, cosmetics, nutraceuticals and other innovative products (NEWMAN & CRAGG, 2012). In addition to the vast biodiversity, Brazil also has a rich socio-diversity, built over the centuries by the miscegenation of Amerindian, African and European cultures (VALLI & BOLZANI, 2019). However, despite its recognized potential, native vegetation in Brazil is undergoing an intense process of destruction, caused by a sequence of highly impactful economic cycles, which began with the exploitation of pau-brasil, in the 16th century (DEAN, 1996). Currently, only 7% of the Atlantic Forest is preserved, while other ecosystems such as the Amazon, the cerrados and the caatinga are being rapidly replaced by monocultures of eucalyptus, sugar cane, soy and cattle raising. The consequences of these processes on useful and medicinal native plants are dramatic: a study carried out by the Center Specialized in Aromatic, Medicinal and Toxic Plants Ceplamt/UFMG (supported by FAPEMIG) between 2004-2005, with the population of the mining area of Estrada Real, in Minas Gerais, showed that, even among the elderly inhabitants of rural areas, knowledge about the medicinal applications of native plants was forgotten (BRANDÃO & MONTEMOR, 2008). As a consequence, most of the plants used today as medicines are exotic species, that is, native to other continents, but which have been introduced here since the beginning of Portuguese colonization (FERRÃO, 2004).

“…Taking into account the pre-test score of 29 and post-test scores of 87, it is observed that the results of this study overlap with Kassimbekova et al (2021). Similarly, Brandão et al (2023) emphasized the importance of medicinal plants and the necessity of teaching them to students in their study "Teaching Medicinal Plants at School: In the Footsteps of Frei Veloso". When the literature is examined, it is seen that the studies are aimed at application in medical gardens and educational gardens (Reyes 2021;Osma, Guapacha and Saavedra 2016).…”

“…Ön testlerinde yüksek yeterlilik düzeyine sahip birey sayısı kontrol grubunda 9, deney grubunda 8'dir. Son testlerde bu sayı kontrol grubunda 12'ye, deney grubunda ise 15'e yükselmiştir.Benzer şekildeBrandão et al (2023) "Okulda Tıbbi Bitkilerin Öğretilmesi: Frei Veloso'nun İzinde" çalışmasında tıbbi bitkilerin önemini ve öğrencilere öğretilmesinin gerekliliğini vurgulamışlardır. Makalede, tıbbi bitkilerin insan sağlığı, ekonomi ve çevre için önemli bir yere sahip olduğu belirtilmektedir.…”
