Most of my friends know I am into making herbal concoctions for hair and body, and I must give credit to where credit is due!
My herbal BIBLE is Rosemary Gladstar's Family Herbal: A Guide to Living Life with Energy, Health, and Vitality.
I purchased this jewel from Scarlet Sage Herb Company in San Francisco many years ago. This book is very detailed and easy to understand with many herbal recipes specifically for women, men, children, and the elders. I especially love her skin and hair recipes. The back of the book contains a detailed encyclopedia (complete with pictures) of all of the herbs mentioned in the book and more. If you are a newbie herbalist or an expert looking to expand your collection, this book is an excellent starting point.
