This book may only be 24 pages long but it has some very good information contained in its pages. Its written well, has good pictures and describes numerous herbs and their uses. It might not go into great detail about the origin of the herbs but it is an excellent refernce book that fits quite neatly into a tack box, making it perfect for stable use (although watch out as the book seems to sprout legs and walk into other peoples possesion!).
It has some very useful recipies that work. This book is essential to anyone wanting to use a more natural way of treating their horse. You most certainly get more than you pay for!
