Rhodiola Rosea for Chronic Stress Disorder

This is a good review of the studies on rhodiola rosea for stress reduction, immunity, depression and mental performance. Complex biological processes are described in easy to understand language, sometimes with diagrams. I thought I knew everything about rhodiola rosea because I sell a private label extract to my clients who are stopping smoking or experiencing stress or fatigue and I have read a lot, but I actually learned a lot of new information from this book. It has a good reference section at the end. I only wish it was a bit longer. Recommended.
