#1 Aloe Vera for Oral Health

Aloe vera tooth gel has been found to be effective in several oral applications. For example, researchers compared aloe vera tooth gel with two popular kinds of toothpaste for their ability to fight germs. Overall, the aloe vera gel was similar to or even better than the conventional toothpaste used when it came to controlling cavity-causing bacteria in the mouth. Aloe vera also has been shown to be helpful in fighting plaque-induced gingivitis.

The dental healing powers of aloe vera come from the anthraquinones that reside in the latex (naturally occurring) in the plant. These compounds relieve pain by reducing inflammation. If you use aloe vera gel, be sure it contains the stabilized gel found in the center of the plant's leaves.

#2 Aloe Vera for Burn Care

We often think of first aid and burn care when aloe vera is mentioned, and for good reason. For example, experts compared the use of aloe vera gel with 1 percent silver sulphadiazine cream to treat second-degree burns. Patients treated with aloe vera healed significantly faster and also experienced significantly more and quicker pain relief than patients treated with the silver cream.

#3 Aloe Vera and Diabetes

Numerous studies have indicated that aloe vera gel is safe for lowering cholesterol and glucose in individuals who have type 2 diabetes. Other research shows that aloe vera can help improve carb metabolism in obese individuals with prediabetes or nontreated diabetes by reducing body weight, body fat, fasting blood glucose, and fasting serum insulin.

#4 Antiviral Properties of Aloe Vera

Want to fight off nasty viruses? Aloe vera gel may be an effective tool. Some research has shown that the gel has antiviral activity against herpes simplex virus type 2. In a recent study from China, researchers reported that polysaccharides extracted from Aloe vera leaves have the ability to fight the influenza virus.

#5 Aloe Vera and Heart Health

For a healthier heart, think aloe vera. Numerous studies show that aloe vera may help reduce the development of atherosclerosis by modifying certain risk factors. For example, aloe leaves helped significantly reduce levels of total cholesterol, total triglycerides, low-density lipoprotein (LDL) cholesterol, and very low-density lipoprotein (VLDL).

#6 Aloe Vera and Ulcers

Extracts of aloe vera leaves are used to promote digestion and treat peptic ulcer while the gel has antibacterial properties against H. pylori, bacteria that are involved in peptic ulcers and gastric infections. For example, one recent Italian study found that aloe vera gel was effective against H. pylori strains, suggesting the gel may be "a novel effective natural agent for combination with antibiotics for the treatment of H. pylori gastric infection."

#7 Aloe Vera and Cancer

Many studies in the lab and in animals have indicated that aloe vera has strong anticancer abilities. One of the compounds in this plant that has potential therapeutic uses for cancer is the main ingredient called aloin. It has shown protective effects against certain precancerous lesions in rats. Other studies have shown that aloe vera can help prevent the proliferation of certain cancer cells, such as lung, squamous, and glioma.

Aloe vera has been the subject of numerous scientific studies, and many of the findings have demonstrated its ability to be a significant force in the management of various health challenges. Speak with a knowledgeable healthcare professional before you take aloe vera for health symptoms or disease.
