Long before Western medical advances existed in any form, the Chinese had a complete and comprehensive system of medical that ran the gamut of ailments that any person could conceivably suffer. Everything from headaches to pulled muscles, and everything in between, had its own remedy. Traditional Chinese medicine has been around for 30 centuries or more, and is still in practice in many parts of the world.
In modern times, a lot of people see traditional Chinese medicine as a very viable alternative to modern solutions. Many of the treatments involves for sicknesses are completely organic, which ends up producing a remarkably short list of side effects compared to modern pharmaceuticals. Even if you don't factor in cost, that fact alone makes it a very attractive fit for people who have decided to choose to live a more natural lifestyle that's more in sync with nature. The number of people that have decided that they are better off minimizing the number of artificial ingredients that enter their body is on the rise, and that's largely what this system of medicine is all about.
