What does it involve?
Practitioners of Ayurveda may combine special diets, Ayurvedic medicines, cleansing, yoga, meditation, massage, breathing exercises, and visual imagery to treat their patients. Ayurvedic medicines often consist of complex mixtures of herbs, minerals, metals, and/or animal products. Ayurvedic cleansing can include special diets, internally and externally applied oils and herbs, massage, nasal washing, sweating, vomiting, laxatives, enemas, and even bloodletting. Gentler cleansing methods may be used for the frail or ill.
To diagnose illness, Ayurveda practitioners closely observe a patient’s tongue, nails, lips, and the body’s 9 “doors”: the eyes, ears, nostrils, mouth, genitalia, and anus. They also listen to the lungs and observe the pulse, then take a detailed history of the patient’s life and health. Through these observations, practitioners claim to evaluate a patient’s doshas, or primary life forces. Practitioners say that each person is dominated by one of three doshas, but is influenced to some extent by all three. The dominant dosha describes a person’s physical, emotional, and spiritual characteristics as well as his or her daily habits and lifestyle.
According to Ayurveda practitioners, balancing a person’s doshas not only enables the various organs of the body to work together, it also establishes a person’s connection to the environment and the cosmos.
When planning a course of treatment, Ayurveda practitioners take into account the state of a patient’s doshas and the relationship between the doshas and other factors such as emotions, illness, physical activity, lifestyle, diet, relationships with other people, and even the four seasons, colors, and the time of day. Practitioners strive to harmonize all of these factors so that their patients can attain health and well-being.
What is the history behind it?
Ayurveda is thought to have appeared in India more than 5,000 years ago. It emerged from an ancient body of knowledge called the Vedas. In fact, veda is the Sanskrit word for knowledge. From these Vedas, India developed its moral, religious, cultural, and medical codes. Many of the beliefs and practices of Ayurveda are similar to those of ancient Chinese medicine.
Ayurveda practitioners in India are trained in state-recognized programs. Today, modern medicine is also available to most people in India, especially in urban areas. One study found that 15-20% of people with common ailments preferred Ayurvedic treatment for them. But more than 80% of Indian people said they preferred modern medicine for serious illnesses.
With the interest in Ayurveda from developed countries, practitioners began practicing and teaching Ayurveda in the United States. Today, there are Ayurvedic clinics and a growing number of training programs in North America. The National Ayurvedic Medical Association (NAMA) web site lists more than a dozen US training programs for those who want to learn Ayurveda. NAMA started by recommending a minimum of 500 hours of training before starting to practice. As of 2011, NAMA is working to standardize levels of Ayurvedic practice in the US based on the practitioner’s areas of competence.
What is the evidence?
Although Ayurveda has been largely untested by Western researchers, there is a growing interest in integrating some parts of the system into modern medical practice. In fact, a few of the herbs and substances have been purified into drugs that are used (along with other medicines) to treat cancer. Early studies suggest that other parts of Ayurveda may have potential therapeutic value.
Laboratory and clinical studies have suggested that some Ayurvedic herbal preparations may contain substances that have the potential to prevent and treat certain types of cancer. Randomized clinical trials in humans are needed to learn about the possible role of Ayurveda in cancer prevention and treatment. The National Cancer Institute (NCI) funded a series of laboratory studies to evaluate 2 Ayurvedic herbal remedies (called MAK-4 and MAK-5). The studies so far have shown some promise against tumors in rats and cancer cells in lab dishes. To date, there are no reports of tests of these 2 herbal remedies in humans.
In a controlled clinical trial of cancer patients in India, researchers found an Ayurvedic herb mixture worked as well as a standard laxative for relieving constipation caused by pain relieving drugs. In 2 small controlled clinical trials, an herb used in Ayurveda (mucuna pruriens ) was found to reduce symptoms in patients with Parkinson’s disease. Many other individual herbs and spices used in Ayurveda are being studied in the laboratory or in animals. Some are already being tested in human clinical trials to find out if they can be used to treat or prevent cancer. These studies use methods of conventional laboratory and clinical research and are intended to find out whether substances used in Ayurveda can be used with conventional cancer treatment. We are not aware of any scientific research addressing the relevance of Ayurvedic concepts, such as cleansing, to cancer treatment. There is no convincing clinical evidence so far to suggest that traditional Ayurvedic treatments can have a substantial impact on the growth and spread of cancer. (For more information, see documents on individual herbs, such as Turmeric . Garlic. Gotu Kola ).
Are there any possible problems or complications?
These substances may have not been thoroughly tested to find out how they interact with medicines, foods, or dietary supplements. Even though some reports of interactions and harmful effects may be published, full studies of interactions and effects are not often available. Because of these limitations, any information on ill effects and interactions
below should be considered incomplete.
Some aspects of Ayurveda, such as enemas, laxatives, bloodletting, and inducing vomiting, can be harmful and potentially cause serious complications. Many people with cancer already have low blood cell counts as a result of the disease itself, and removing additional blood can worsen fatigue and other symptoms. Inducing vomiting or diarrhea can cause imbalances of electrolytes (salt and minerals) in the blood.
The potential interactions between Ayurvedic herbal preparations and conventional drugs and other herbs should be taken into consideration. Some of these combinations may be dangerous.
There have been reports of lead, mercury, and arsenic in some Ayurvedic herbal preparations sold in US and international markets. Between 1978 and 2009, more than 80 cases of lead poisoning were reported in the medical literature in people using Ayurvedic mixtures. Patients with lead poisoning can suffer nausea, vomiting, abdominal pain, miscarriage, and/or anemia. Because these symptoms occur with many other illnesses, it is likely that many people who have lead poisoning are never suspected of having it. Even when cases are found, very few are actually reported in medical journals, so this is but a fraction of the actual number of people affected.
Some people have allergies to certain plants and may react to combinations of Ayurvedic mixtures that contain them. Some people taking Ayurvedic herbal medicines have had serious heart rhythm problems and low blood pressure from taking too much of the herb aconitum or aconite.
Enemas also have some dangers. Illness and even deaths have resulted from contaminated equipment, electrolyte imbalance, or perforation of intestinal walls. People with certain diseases of the colon may be at higher risk of bowel injury. In addition, fluids, herbs, and other substances that are added to the enema can be absorbed into the body through the colon walls. In some cases, this can result in fluid overload, toxicity, or allergic reactions. For more on this, see our document called Colon Therapy .
Always tell your doctor and pharmacist about any herbs you are taking. If you use Ayurveda, it should be delivered by a trained therapist who knows all of your medical history and allergies.
Relying on this type of treatment alone and delaying or avoiding conventional medical care for cancer may have serious health consequences.
