The book "Mineral distribution in some Amazonian plants" by Marcelo Barcellos da Rosa offers a comprehensive analysis of the mineral composition of selected plant species from the Amazon region, known for their medicinal properties. Brazil, with its rich flora, particularly in the Amazon rainforest, is a promising area for the exploration of medicinal plants. This work examines specific species such as Cecropia palmata, Cecropia obtusa, Bauhinia variegata L., and others that are common in the region and utilized by the local population. The study highlights the high concentrations of essential minerals such as calcium, potassium, magnesium, zinc, copper, manganese, and iron found in these plants. At the same time, it notes that the levels of harmful elements such as chromium, nickel, cadmium, mercury, arsenic, and lead are low, indicating the safe use of these plants. This book is a valuable resource for scientists and those interested in botany and the medicinal applications of plants.
