from kidshealth.org, and I am posting this so we can all be on the same page as far as facts are concerned.
A bruise is also called a contusion (say: ken-too-zhen), and it forms after a hard enough bump to the soft tissues under your skin. When these tissues are injured, small veins and capillaries (the tiniest blood vessels) under the skin sometimes break. These blood vessels then leak out red blood cells.
The red blood cells that collect under your skin are what cause that bluish, purplish, reddish, or blackish mark. That’s where black-and-blue marks get their name - from their color on the skin.
Some people bruise easily whereas others may have tougher skin tissue. Despite the many ways you can get them, bruises pretty much go through the same colorful changes as the body begins to heal itself.
A bruise will turn nearly all the colors in the rainbow before it finally fades away. The color changes mean that your body is metabolizing (say: meh-tab-ah-lie-zing), or breaking down, the blood cells in the skin. This is the chemical process that your body goes through to repair itself.
Imagine you’re hit with a baseball in the leg. Ouch! Your body will go through the following phases:
First, you’ll probably have a bump that will probably look red or purplish and tender. The bump might swell from the blood collecting under the tissue.
After a couple of days, the bruise will look blue (or even blackish).
After 5 to 10 days, it may look greenish or even yellow.
After 10 to 14 days, the bruise will most likely be a light brown, then get lighter and lighter as it fades away.
Most bruises will disappear after 2 weeks, and some go away even sooner. However, if a bruise does not go away after 2 weeks, you should let your parent know. To help reduce swelling or the amount of bruising after an injury, apply a cold compress to the bruise for at least 10 minutes. And next time you’re playing hard, wear your protective pads or gear to avoid bruises altogether!
ok, so now we all know exactly what a bruise is.
As for dit da jow, this medicine speeds healing by increasing the speed of the healing process along with the massage.
I believe the reason that a cold compress is used in teh above example is because a cold compress will stop the blood from flowing and will slow the bruise and decrease the immediate damage and swelling.
Dit Da Jow is used to speed the healing and you will heal faster than you normally do when you bruise provided the jow is of the correct recipe for what youa re using it for.
IE: there are quite a few jows that do nothing but make your skin sticky and smell bad lol. These are easily identified by not helping the bruise to heal faster. As it says, better to avoid this kind of damage and to condition your toughness slowly and over time. Patience is required and those with a lot of zeal have little patience, hence their frequent injury.
Take it easier, you’ll get there.
