There are many stories about Bush Medicine being used to cure or aid in the treatment of cancer. This is particularly so in Western, and South Australia where the bush seems to have been used most. Many people who used the bush for this would vouch for the healing and extra life it has given them. Others who, like myself, have used it for a variety of illnesses have experienced exciting results
Some of these success stories may be difficult to “prove”, for several reasons. One being that most cases are not well documented. This is perhaps because alternative or holistic treatments for cancer and illnesses do not generally reach the forefront of  medical reports and information. Many people who took the Bush Tea did so "on the quiet", and of course evidence is lacking.
Mainstream medicine has shown a disinterest in the bush. However there has been several scientific studies done, with some ongoing. One current study is showing exciting results, and I am privy to a little of it, but at this stage nothing can be published.

It does not take long researching this “bush” to discover that both the properties and the effects of it are hard to pin down. One of the reasons for this is what is called a synergistic effect. This is where the whole of something as a complete unit works together to produce the effect. Many of the tests and analysis of the plant have been done by extracting certain components to see if or how they work. Often, probably because of this,  with little or unclear results. If the plant product actually works synergistically, then breaking it down also breaks the synergy, and destroys its effect.
Some who used the bush did so as a last resort, not really giving it a good chance, and yet even some of these experienced excellent results or significant improvement. History shows that mainstream medical treatments also work a lot better when used early!
Immune System and Diabetes.
My own experience and others supports the view that Maroon Bush has a powerfull effect on the immune system.
There also seems to be significant benefits in aiding the treatment of diabetes. There are several cases of people reporting a significant drop in the need for medication when using the extract. My personal belief is that the bush medicine boosts the immune system dramatically.
There are many people who are convinced they owe their health, and recovery from cancer to the Bush Medicine in the past, whether this is the case should be decided by individual research.
