I've never been a fan of Doctor OZ! Groups of notable physicians are collaborating to take Dr. Mehmet Oz MD, to task on what they’re calling outlandish claims and bad medical advice. Their suggestion is to no longer pay attention to that man behind the curtain!
Read this about your dog licking you and your wounds, straight from from the University Of Florida Medical Research Labs....
"Researchers at the University of Florida at Gainesville have discovered a protein called Nerve Growth Factor (NGF) in saliva. Wounds that were treated with NGF actually healed twice as fast as untreated wounds, indicating that if a dog does lick a humans wound, it could in fact lead to a faster recovery. In addition, Dr. Nigel Benjamin, a clinical pharmacologist with St. Bartholomew’s Hospital and the London School of Medicine and Dentistry, has conducted research indicating that when saliva comes into contact with skin, a natural component of saliva called nitrite, breaks down into nitric oxide, a chemical compound that is very effective in protecting cuts and scratches from bacterial infections.
The scientific research that has been conducted has mainly focused on the helpful compounds and antibiotics that are found in dogs saliva. Menno Oudhoff of the University of Amsterdam has found simple proteins called histatins in saliva, which are well known for their ability to ward off infections. In fact, some histatins also prompt cells from the skin’s surface to close over a wound more quickly. Oudhoff further noted, “The first thing that needs to happen for wound healing is to activate the migration of epithelial cells.”
Note that there are some dangers of letting a dog lick a DEEP open wound, so always take precautions. The anaerobic bacteria called Pasteurella is found in dogs saliva as well and can cause serious infections when introduced deep into an open wound.
Although the healing properties outweigh the negative impacts, there will always be a number of people who find it in their best interest to treat a wound by cleaning it with soap and water, then covering with an antibiotic cream and a bandage."
