I love essential oils and have used them for several years. I am completely uneducated on the herbal aspect of healthy living. This book has been a godsend for my education. Thanks to this book I am beginning to learn and appreciate herbs and herbal remedies. This book has improved my ability to keep myself healthy. This book explains the information in a simple way that even a novice can understand. I appreciate that Mrs. Westover adds some experiences and preferences in her commentary. It helps me know where to start. Jumping in can be very intimidating but the information in this book helped me find the confidence to just start somewhere.
