Inflammation is the word that we use to describe the immune systems' hyper reaction in a part of the body. We often experience this as heat, because there is a general assumption by the immune system that when something is wrong in the body, there is a foreign invader, such as a bacteria or virus, that needs to be killed off with heat, and so the body automatically raises the set temperature to assist with this. There is also heat experienced in a local area when the body send chemical to literally burn up foreign invaders by generating chemicals with extra oxygen molecules to the area. The ancients referred to this as Calor (heat), and it brings with it: Rubor (redness), Dolor (pain), and Tumor (swelling).
If there is a bacteria or virus present, then this process helps kill off the invasion (or in the case of a virus, sends it into dormancy), and then everything calms down and the inflammation dissipates. But in the post-modern world, we have come to realize that really, it is only certain bacteria that trigger these reactions in the body, and only in some people. It turns out that there are trillions of bacteria in the human body, and we actually have more bacteria in us than cells. So what is it about certain bacteria or viruses that trigger these reactions in certain people at certain times? And why does the inflammatory process go haywire in certain people, so that their immune system begins to attack their own tissues?
Genetics seems to play a role in some of these processes. We have already identified certain gene mutations that predispose people to certain errors in the immune system, and all indications are that we will find more. But these gene mutations seem to have another mechanism, that over time, regulates them, and this is called epigenetics, or soft inheritance. Epigenetics involves the adding or removing of small chemical groups that decide which genes are available for transcription and which aren't, and the indications are that genes that are shut down or stuck on for long periods of time become vulnerable to mutation, and this is the constant dynamic of adaptation that Nature has used to govern our relationship to our environment.
Although we are only at the beginning of our understanding, already we know that certain herbs and certain gut bacteria have particular effects on epigenetic markers and can be used to effect them. One well known herb that has been studied for its epigenetic ability to turn off the inflammatory process is curcumin, but there are many other herbs that can be used in this way.
Working with Nature to turn off inflammatory processes through epigenetics is a much safer alternative to using steroids that also turn off the protective mechanisms of the immune system.
