Animals Whose Healing Powers Might Surprise You

Some pet owners just love to get some sloppy kisses from their four-legged fur babies at the end of a long, hard day of work, but for others, dog drool is just plain gross. Like it or not, though, there's a reason our canine pals are so quick to use their tongues. Licking wounds is actually an instinctual response in dogs and other animals alike (yes, even us humans), because their saliva has tissue factors which promote blood clotting, which in turn is responsible for the scabs that stop a cut from bleeding freely. They can also ward off serious pathogens that might infect their puppies, which is why it's common to see a nursing dog giving her newborn regular tongue baths.

But experts caution against humans turning to their pooches for some salivary support in times of need, because while doggy dribble is great for healing their own open wounds, they also contain a bevy of bacteria that could be harmful for us two-legged types. Dogs' mouths commonly contain bacteria called pasteurella and bartonella, which can cause infection to humans whose gashes are exposed to some of those delicious doggy kisses. They can also harbor parasites that can have serious consequences when spread to people. In other words, while dogs might be able to speed up their own wound recovery process with a little lip service, owners should stick to stocking the medicine cabinet for their own boo-boo treatments.

Snakes are some of the most universally feared animals on the planet because, even though the vast majority aren't venomous, one bite from a poisonous snake can be deadly. However, researchers also have reason to believe that even the scariest of these slithery beings could be helpful to humanity as well. According to the New York Times, neurologists have linked the venom from the Malayan pit viper — an animal known to cause fatalities with its gashing bite — to dissolving blood clots.

The properties of the venom, experts say, can decrease the thickness of blood, preventing the kind of clots that cause many human strokes to become severely disabling, or even a death sentence. By purifying the substance, and giving it to stroke victims within a limited window of time, these experts believe they can reverse the potential for the clot to be life-threatening or cause irreparable brain damage, saving lives and increasing quality of life for stroke survivors as well.

According to researchers from the University of Missouri, children within the spectrum of autism can benefit greatly from having a pet in the home. Among the patients studied for the team's project, kids who had pets of any kind were much more apt to socialize with others, compared to those who didn't.

Gretchen Carlisle, one of the study's conductors, told The Daily Mail, "These kinds of social skills typically are difficult for kids with autism, but this study showed children's assertiveness was greater if they lived with a pet." She added that even when the child wasn't quick to interact with others, the presence of a pet served as a conversational ice breaker of sorts. "Kids with autism don't always readily engage with others, but if there's a pet in the home that the child is bonded with and a visitor starts asking about the pet, the child may be more likely to respond," she explained.

With humans, one traumatic wound can lead to severe bleed-out or infection and can be fatal, but dolphins can patch themselves up from the nastiest of gashes with amazing speed and continue on with their daily lives, relatively uninhibited by pain. Dr. Michael Zasloff from Georgetown University told NPR in 2011 that he believes properties that make the underwater mammals so resilient could be beneficial to us landlubbers as well. "Dolphin blubber makes compounds like organohalogens that act as natural antibiotics and keep the tissue from getting infected," he explained. "When the animal restores its wound, it regenerates the complex structure of blubber. It doesn't create a scar; it produces a sort of patch that ultimately is woven back into the surrounding tissue."

The potential for that healing property to translate to humans, he explained, is in the involvement of stem cells, which may contain proteins that could help heal our own wounds ... while limiting the pain process as well. By investigating the tissues that makes up dolphins' blubber, researchers hope to isolate the microbial agents that destroy the dangerous bacteria that would make such wounds fatal in people and find the "long-sought natural morphine that we've been looking for."

In 2015, researchers in the United Kingdom discovered a potential chemical link between hibernating bears and humans who suffer neurodegenerative disorders, like Alzheimer's Disease and dementia. As detailed by BBC, scientists studied the sleeping bears and discovered that, while they slumber through the winter, 20 to 30 percent of their cranial synapses shut down. This part of the bears' brains were successfully reawakened when their bodies returned to the outside in spring.

They discovered that the chemical which allows for this phenomenon is RBM3, which experts believe could be introduced to patients suffering from neurodegeneration, to prevent brain cells from dying off as they normally would during the onset of those diseases. The hope is that memory loss and diminishment of functionality could be prevented by application of an artificial version of that agent.
