For a long time before the advent of modern medicine, people tried to use a variety of unique and material diseases, such as earthworm meal, rat droppings, hare teeth, dried toads.
Don't say it, some of these weird ** do work.
Before the invention of the toothbrush, many people would use the branches of the toothbrush tree to clean their teeth.
The toothbrush tree grows in the tropical forests of Africa, and the woody fibers of this tree are interesting, take a toothbrush-sized branch, peel off a section of the bark, and then hold the wood inside in your mouth.
When the branches are soaked with saliva, the wood fibers will spread out and become toothbrush-like hairs, and the fiber pores of the branches will secrete some milk, just like toothpaste, which can remove tartar, and it is also fruity, which is quite magical.
Recent studies have found that the tree's wood releases an antimicrobial liquid that prevents tooth infections and tooth decay. The tree even contains fluoride, which helps keep your teeth strong.
The medicinal application of honey and sugar dates back thousands of years. In ancient times, whether in Egypt, Rome or Mexico, doctors would use a paste made of sugar or honey to **burn and cut.
Sugar can dehydrate bacteria and die, while honey contains antibiotics that kill certain bacteria. Both have antimicrobial properties, reduce edema, promote autolytic debridement, stimulate macrophage migration, and promote the development of granulation tissue.
When used properly, honey and sugar are great options in the early stages of wound healing and can speed up the patient's development.
Leech is a black insect with fine lines on its body. It prefers to drink animal blood the most. Before the 19th century, leeches were the top of the pharmaceutical industry.
Legend has it that Napoleon had to rely on it to cure hemorrhoids ......
For the sake of ** patients, the ancient Greeks would sometimes try to use a few leeches to suck away the "bad blood". After the leech is "full of wine and food", it will fall from the patient with a stomach full of "bad blood".
Later, the German doctor Michelsen found that the use of blood-sucking leeches ** knee arthritis is very effective, compared with aspirin and other physical ** methods, the effect of leeches ** is very good. He once put four leeches on the knee of a patient with severe knee pain for 80 minutes, and the patient only felt a little discomfort at first, but soon after.
In fact, the key to the leech's "pain reduction" lies in the anti-inflammatory components of its saliva. It has been discovered that leeches contain a chemical called hirudin, which prevents blood from clotting. Modern surgeons, when dealing with tiny blood vessels, sometimes use hirudin to prevent blood clots from blocking the flow of blood.
The ancient Greeks, Egyptians and Native Americans, whenever they had a headache and fever, they would mash it with willow bark and apply it to their foreheads to relieve the pain. Therefore, they call the willow tree the magic tree.
People have been puzzled about this for a long time.
It wasn't until 1975 that Cleland, an American plant physiologist, discovered by chance that mashed willow bark sap contained salicylic acid, the main ingredient for making aspirin pills, thus unraveling an interesting mystery.
It turns out that the "magic" of the willow tree is that it contains natural aspirin, which has an antipyretic and analgesic effect.
