Gall , from Latin galla, is a term with multiple uses. It may be the round excrescence that is formed in certain trees and shrubs from the bites of some insects and infections produced by microorganisms.
For example: "On the trunk of this oak, we can observe the gills that reveal the attack of an insect", “This tree has so many guts that it has lost its original form”, "The cork oak is characterized by its gills, which it exhibits along its trunk".
Tree guts are extrusions that hang as if they were fruits; in the case of oaks, in fact, they are called oak apples and they originate after the wasps lay their eggs inside their bark. Galls have a high value of tannic acid and have long been used for the manufacture of medicines in many parts of the world.
While all oak gills appear by the action of the so-called gill wasp, vary in shape, color and size. The larvae of this species force the oak to create substances and cells that generate the gills, which in turn are used by the former as a source of food and as a refuge. It is worth mentioning that they usually do not represent a danger to the tree even if its formation is an act of defense on its part, which explains its high content of astringent compounds (it is believed that these gills are the compound most astringent organic vegetable on the planet).
The medicine China takes advantage of them as a remedy to treat, for example, hemorrhoids, ulcers and dysentery (infectious disease characterized by diarrhea with blood and bids). In North America, on the other hand, the Indians used them to heal various wounds, burns and sores. Finally, some specialists recommend them to combat gonorrhea, diarrhea and cholera.
Outside of medicinal uses, the acid Tannic gills makes them an ideal source for dyeing and tanning; various tribal groups have taken advantage of them to create different types of ornaments and curing, to work leather, ceramics and to make baskets.
Since, in principle, gills arise as a protection by the oak tree towards the action of wasps and their larvae, science has also been interested in their use as a natural pesticide. Researchers at the University of Mysore, in India, declared in 2009 that they had observed an effective larvicidal activity in the fight against the mosquito species to which the spread of malaria in urbanizations is attributed, the stephensi anopheles.
The guts are also the sides of the head of a bird, equivalent to the temples, the gills , waves tonsils : “If the fish is fresh, the gills should be reddish”, "It is a kind of small gills and short fins", "This disease attacks the gills of the fish".
In colloquial language, the use of the notion of guts is linked to the audacity wave courage : "You have to have guts to do something similar", "The judge did not have the guts necessary to respond to the victim's father", "Without guts, the battle is lost".
Guts It is also the name by which it is known in Spain to the main protagonist of Courage the Cowardly Dog , an animated series that in Latin America received the denomination of Courage the Cowardly Dog . Guts or Courage It is a dog that is always scared, but that strives to save the lifetime to its owners from attacks by monsters, aliens and other creatures. The series was aired between 1999 and 2002 , although their repetitions can still be seen.
