Phytochemicals in Clinical Studies: Current Perspective

  • Chapter
  • First Online:
Functional Food and Human Health

Abstract

Natural plants and their derived products are effective against various diseases for their prevention and treatment for several years. Availability of synthetic drugs with faster and selective responses against various diseases decreased the use of herbal products. However, due to adverse side effects of synthetic drugs, in the last few years, the clinical use of plant-derived medicines has been exponentially increased in developing as well as developed countries due to their easy availability, low cost, and least toxicity. Therefore, in recent years, several human trials have been done to analyze the toxicology, pharmacokinetics, and biologically effective dose of phytochemicals against cancer, diabetes, and bacterial and viral diseases for their clinical application. In the present book chapter, we have discussed the clinical studies on phytochemicals against several diseases including diabetes, cancer, and diseases associated with microbial infections including women health problems.
