In German Language :The best little handbook I have ever seen. It describes in very short ways all 12 Schuessler Cell salts and the additional cell salts up to number 24. the numbering is the original Schuessler way and not the american way. The book lists all possible ailments and gives recommendation on treatment also the amount of celol salts you should take. This book is a small pocket book which you can carry in you purse easily. no useless talking no endless explanation. all short and very well done in overwiev.
