"There is hope for herbalism and natural healing in the 20th century. Everywhere a revival of interest and a new spirit of inquiry are evident... The debt to plants as the original sources of valuable modern medicines is today more readily acknowledged... The current revival of interest in the values, properties, and uses of nature's products gives hope that thousands of years of accumulated knowledge will not be completely buried in the stampede so dubiously named progress."
- John Lust, The Herb Book
