My wife purchased this item on my prime account, so here is her review:
I had been reading about cell salts in a few places and wanted a reference book. I got recommendations from a few sources and this book and a biochemic book kept coming up. I ordered this through amazon due to price, availability, and free prime shipping. I got the biochemic book and Luyties cell salts (all 12 plus bioplasma) through 1800homeopathy.com.
Between my two books, anyone in my family can look up symptoms or cell salts and cross-reference the books and self-diagnose with confidence. The biochemic book is good for quick use and brief answers. This book gives a better understanding of cell salts and how they work and more complete answers and case studies. The two books complement each other well and I have not felt a need to buy any others. I love cell salts!
