Herbal medicine is a very popular alternative to modern drugs. This series of books explain how herbs work, advise on herbs suitable to remedy specific complaints, as well as giving instructions on making your own herbal remedies from raw ingredients.
This is a good book, just not useful to me. It is intended for Europe, US, Canada and its neighbors. Many of herbs mentioned aren't either available in India or are overpriced. If you are from the above countries, it may come of use. Science behind is explained very well. It is a waste that it isn't useful for me especially considering it was published by a publisher from my own city.
