Herbal complexing agents, which encompass both active phytoconstituents and pharmaceutical excipients, provide novel approaches to addressing these issues by employing various molecular complexation mechanisms. This book goes into detail about the basic ways that complexation works, such as supramolecular interactions, inclusion complexation (like cyclodextrins), phyto-phospholipid complexation (like phytosomes/herbosomes), and metal chelation. It goes into more detail about their important uses in the pharmaceutical industry, such as improving drug formulation and delivery, which makes drugs more soluble, stable, and available to the body, and allowing for more advanced drug delivery systems.
