By a News Reporter-Staff News Editor at Biotech Week -- A new study on Drugs and Therapies is now available. According to news reporting out of Araraquara, Brazil, by NewsRx editors, research stated, "Herbal medicines have been widely used around the world since ancient times. The advancement of phytochemical and phytopharmacological sciences has enabled elucidation of the composition and biological activities of several medicinal plant products."
Our news journalists obtained a quote from the research from Sao Paulo State University, "The effectiveness of many species of medicinal plants depends on the supply of active compounds. Most of the biologically active constituents of extracts, such as flavonoids, tannins, and terpenoids, are highly soluble in water, but have low absorption, because they are unable to cross the lipid membranes of the cells, have excessively high molecular size, or are poorly absorbed, resulting in loss of bioavailability and efficacy. Some extracts are not used clinically because of these obstacles. It has been widely proposed to combine herbal medicine with nanotechnology, because nano-structured systems might be able to potentiate the action of plant extracts, reducing the required dose and side effects, and improving activity. Nanosystems can deliver the active constituent at a sufficient concentration during the entire treatment period, directing it to the desired site of action. Conventional treatments do not meet these requirements."
According to the news editors, the research concluded: "The purpose of this study is to review nanotechnology- based drug delivery systems and herbal medicines."
