Diabetes affects our blood vessels and nerves and therefore can affect any part of the body. However, certain parts of our body are affected more than other parts.
I don't think dogwoods have (much?) scent, maybe just lightly floral. The white petally looking things are not actually petals they are bracts, like a poinsettia has. There's something called an English dogwood that is very fragrant, but it isn't a true dogwood and is also known as mock orange. Bradford pears have a smell that this author described as sweaty socks, so if your tree doesn't smell very good that's probably it: http://www.gardenguides.com/106133-dogw ...
The Dogwood has a rich history other than a pretty landscape tree. The name Dogwood could be attributed to two different sources. Dogwood is a very hard and strong wood, and it was said that the term Dogwood could have easily evolved from the Celtic word dag, dagga, or dagwood over the years.The wooden dagge was simply a useful, pointed tool.t the time of the Crucifixion, it was said that wood from the Dogwood tree was selected to fashion the cross. This distressed and saddened the Dogwood tree so much that Jesus took pity on the tree, and promised that Dogwood trees will never again grow large enough to use the wood for a cross.
