In India, there are Doctors of Ayurveda who see patients in Ayurvedic Hospitals and local clinics. Vaidyas, the Ayurvedic Doctors, who move to the US are not allowed to practice to their full capacity here unless they are also MDs but many have spoken of the apparent miracles they saw in their practices in India.
Here in the US, many people come to Ayurveda or Traditional Chinese Medicine after they have exhausted all the treatments that westernized "conventional" medicine has to offer with little or no relief. At this point where a serious disease has already manifested even Ayurveda may not cure the disease but only help one manage it. According to Ayurveda, there are six stages of the disease formation process and disease can be prevented or cured if changes are made in diet and lifestyle in the first four stages. By attacking the root of the potential disease one can prevent the disease.
In cases where the disease is rooted in exposure to toxins one must also either remove the toxin from the area of exposure or remove oneself from the area of exposure before then taking the diet and lifestyle steps to help clear the toxin from the tissues (this might require a specialized process called "Panchakarma", a protocol used for thousands of years to help detoxify the body). The exposed person must then remain vigilant and continue to support the body's health and learn to understand how small seemingly trivial symptoms such as intestinal gas formation, acid reflux, headaches, or fatigue could point to the accumulation of the "Doshas" (the arrangements of the Five Elements that make up the body's structure and govern its functions), the aggravation of the "Doshas" in their normal sites of accumulation, the overflow of the "Doshas" into neighboring sites, and deposition of the "Doshas" into sites of weakness that then will become the first manifestations of the disease.
Once the initial symptoms of the emerging disease become apparent, westernized "conventional" medicine can begin to treat but some diseases are easily cured while others are not. At this stage and beyond Ayurveda and TCM can still provide supportive care, improving and maintaining the strength of the patient while s/he is undergoing standardized treatments.
Below is a link to a brief article about the possibilities of using Ayurveda and Traditional Chinese Medicine to support patients with mesothelioma, a disease resulting from exposure to asbestos. If you know someone with this disease or simply wish to learn as much as you can feel free to explore the rest of the site for information about symptoms, standard treatments, the different ways the disease can manifest, as well as resources for veterans and others.
