Diabetes has been recognized by western medicine since the early 1800's as being one of the most prevalent and controllable conditions affecting a large portion of the population. However, Asian cultures have recognized this fact much earlier and and have developed and been using herbal treatments for diabetes for centuries. These treatments are widely regarded as effective, even today.
It must firstly be recognized that most of the herbal treatment for diabetes are not recommended for those requiring insulin treatment. This is because the majority of the herbs being used have proven effective in helping to restore the body's ability to control the blood sugar level by boosting the effectiveness of the body's own insulin. If the body is not producing insulin there is nothing to boost and, research suggests, the use of these herbal treatments will not have the needed effect.
This has obviously produced the skeptics who claim that the proponents of herbal medication are in the business simply for the money and find argument against the use of herbs in medicine. Conversely, the herbalists claim is that since the drug companies cannot patent herbs and other herbal treatments for diabetes, they cannot make money from their use therefore they condemn them as ineffective.
