The story of the compass is shrouded in mystery and myth, yet most will agree it begins around the time of the birth of Christ in ancient China. A mysterious lodestone whose powers affected metal was known to the Chinese emperor. When this piece of metal was suspended in water, it always pointed north. This unexplainable occurrence led to the stone's use in feng shui, the Chinese art of finding the right location. However, it was the Italians, more than a thousand years later, who discovered the ultimate destiny of the lodestone and unleashed its formidable powers. In Amalfi sometime in the twelfth century, the compass was born, crowning the Italians as the new rulers of the seas and heralding the onset of the modern world. Retracing the roots of the compass and sharing the fascinating story of navigation through the ages, The Riddle of the Compass is Aczel at his most entertaining and insightful.Binding Type: Paperback

It Doesn’t Burn
Size: 4.3 Ounce (Pack of 1)
Toothpaste burns my mouth. Idk why. Started during menopause along with the many other things that changed about myself. I do like it. It doesn’t burn. But, it doesn’t give me that clean feeling.

Pricey but great for people who need something gently on the tongue or mouth
Size: 4.3 Ounce (Pack of 1)
Great alternative to traditional Toothpaste. Its a bit pricey but if you are like me you dont have to share it with anyone else because they can use regular toothpaste. The minty flavor is subtle but does not cause irritation. Easy to just just like regular toothpaste. it doesnt have any whitening in it but is a comfort for those that need a toothpaste gently on the tongue or mouth. Still does the job

Great for people on medication that causes dry mouth
Flavor Name: Cinnamon, Size: 230 Count (Pack of 1)
I pop two of these in my mouth every evening when I get ready for bed. They stick to my gums and cause me to produce just the right amount of saliva during the night; this I don't wake up with cotton mouth!
Actually, most mornings I wake up to find I still have a little bit of the XyliMelts adhering to my gums-- even after 7 or 8 hours of sleep!
I really like the spicy Cinnamon taste- I almost want to eat them just for the taste (but I don't know if that's such a great idea!)
