Open Access Medical Books

Individuals are increasingly taking personal responsibility over their health, both in 
the prevention and treatment of disease. This is particularly true for a wide variety of 
chronic or incurable diseases such as cancer, diabetes, arthritis or acute illnesses 
readily treated at home like common cold. During the last fifty years the practice of 
herbalism has become mainstream throughout the world. This is due in part to the 
recognition of the value of traditional medical systems, particularly of Asian origin, 
and the identification of medicinal plants from indigenous pharmacopeias that have 
been shown to have significant healing power, either in their natural state or as the 
source of new pharmaceuticals. When mixtures of several crude extracts are used in 
formulations, enhancement of the beneficial effects or greater toxicity is expected 
through either synergistic amplification or diminishment of possible adverse side 
effects. It is also presumed that their combination could prevent the gradual decline in 
efficacy that is frequently observed when single drugs are given over long periods of 
time. Nowadays such remedies can still be found in ethnic and health food stores, but 
are also available in pharmacies and grocery stores. Unfortunately there is no 
universal regulatory system that ensures that these remedies are what they say they 
are, do what is claimed, or most importantly, are safe. Many patients with chronic 
allergic conditions seek complementary and alternative medicine therapies. This trend 
has begun to attract interest from mainstream health care providers and scientific 
investigators and has stimulated government agencies to provide support and 
guidance for the scientific investigation of complementary and alternative medicine.
This effort may lead to improved therapies and better health care/patient outcomes.
This book presents an update on the most promising herbal remedies. The objectives 
of this book were to determine the bioactivities of herbal medicines by giving some 
examples of recent research outputs. Results of this study are aimed toward helping 
avoid potential drug-herb interactions; helping decision makers to decide on the 
proper policies in the medical and the non-medical fields concerning herbal remedies 
and other types of complementary and alternative medicine.
