I heard about cell salts a few years back and was intrigued at the concept. I went on Amazon and purchased three different cell salts books. I rarely refer to the other two because this book is all I need. It is well written, most thorough and the layout makes it very easy to find what you are looking for.The first part of the book is a history of cell salts. The author devotes the next section to an overview of 'families' of cell salts. He then goes into great detail on each cell salt, one by one. This makes for fascinating reading, especially for someone like me who had no knowledge of cell salts before. The second half of the book is taken up with individual symptoms and remedies and is very well done.Mr. McCabe emphasizes that we should not wait until an event happens that might require the use of cell salts but to familiarize ourselves with the cell salts before the fact. That is very, very true.A few months after acquiring the book and purchasing the twelve cell salts, an occasion arose that gave me the opportunity to see if this cell salt business really worked. I was sitting at my computer and realized that I didn't feel so hot. Around my eye sockets, I felt flushy, my tummy was queasy and I was aching here and there. I thought "Oh no... the flu." Well, grabbed the book, looked up flu and.. there it was. It mentioned taking 4 different cell salts for 'stubborn cases of flu' in water, sipping the mixture frequently until symptoms abate. Well, that's the remedy I went for.. no half measures, ya know?I remember thinking, "yeah.. right" as I mixed up the concoction. I announced to the family that I was sick and they were on their own and went to my bedroom to crash. I sipped like crazy for an hour or so. Then I fell asleep for 2 - 3 hrs and woke up feeling human. Mixed up another glass full and even managed to eat some dinner. I still felt a little weakish and unsteady but I had lost that 'green' feeling. I thought I had it made but, the next day, I had a few unsteady spells so sipped on a few more glasses. By the day after that, I was right as rain. It was amazing.Since then, I have used the flu cure once last year for myself again and just this past week for my husband. He said his stomach was queasy, he felt lousy and his forehead felt warm to me. He thought I was nuts when I suggested my 'sip water/cellsalts' cure...(I had my fingers crossed ... lol). He sat in the recliner, head down, all listless. I sat right with him reminding him every few minutes to 'SIP'! After about a 1/2 hour his head was erect and he even commented about something on tv. A little later, he said his stomach was ok. He finished that glass and sipped on another the rest of the nite. He even ate a good dinner. I kept a glass of water/cell salts in the fridge for him to sip on throughout the next day but he was fine.I think the trick with cell salts is to apply them as soon as an event happens or at the first sign of a cold or flu or headache. They are amazing little things, these cell salts. I am so grateful that Mr. McCabe took the time to write a book like this that can be used by the amateur (like me) or the more advanced student.
