Ayurveda: The Science of Self Healing by Vasant Lad
You can purchase the book HERE at Amazon.com
Vasant Lad's best-selling book clearly explains the history, principles and practical applications of Ayurveda. Many beautiful illustrations, diagrams and charts accompany the text.
It was the first book that I read. It's basic, but a good introduction.
Let me know what you think :)
