Ayurveda Basics Book

[Jordan Tucker]

Consideredby many scholars to be the oldest healing science, Ayurveda is a holistic approach to health designed to help people live long, healthy, balanced lives. The term Ayurveda is taken from the Sanskrit words ayus, meaning life or lifespan, and veda, meaning knowledge. It has been practiced in India for at least 5,000 years, and has recently become popular in Western cultures. The basic principle of Ayurveda is to prevent and treat illness by maintaining balance in the body, mind, and consciousness through proper drinking, diet, and lifestyle, as well as herbal remedies.

There are two main types of Ayurveda: traditional and Maharishi. Maharishi is a version of traditional Ayurveda based on translations from the classical texts by Maharishi Mahesh Yogi. Both types of Ayurvedic practitioners:

Maharishi Ayurveda emphasizes the role of supreme consciousness in maintaining good health and promotes transcendental meditation (TM) as a way to experience the pure consciousness of the universe. It also highlights the expression of positive emotions and the need to attune your life to the natural rhythms of your body.

According to Ayurvedic beliefs, just as everyone has a unique fingerprint, each person has a distinct pattern of energy, a specific combination of physical, mental, and emotional characteristics. Ayurvedic practitioners also believe there are three basic energy types called doshas, present in every person:

Everyone has vata, pitta, and kapha. But usually 1 or 2 are dominant in a particular person. Many things can disturb the energy balance, such as stress, an unhealthy diet, the weather, and strained family relationships. The disturbance shows up as disease. Ayurvedic practitioners prescribe treatments to bring the doshas back into balance.

From a Western medical perspective, stress relief seems to be one of the ways Ayurveda works to help fight illness. For example, studies have found that transcendental meditation (TM), a component of Maharishi Ayurveda, lowers anxiety. Other studies have found that Ayurveda lowers blood pressure and cholesterol, slows the aging process, and speeds recovery from illness. Many herbs used in Ayurvedic medicine have antioxidant effects, meaning they may help protect against long-term illnesses, such as heart disease and arthritis. Many Ayurvedic practitioners also recommend a vegetarian diet which is believed to be better for your heart than diets containing red meat.

Ayurvedic treatment focuses on rebalancing the doshas. On your first visit, the practitioner will take a detailed medical history, check your pulse, feel your abdomen, examine your tongue, eyes, nails, and skin, and listen to the tone of your voice. The practitioner will also ask you questions about your general health, paying special attention to your lifestyle, diet, habits, and surroundings. The practitioner will then recommend ways to restore your natural dosha balance, which almost always includes changes in lifestyle, especially diet. Practitioners draw from more than 20 types of treatment. The most commonly prescribed include:

The goal of Ayurvedic medicine is to prevent diseases. Studies have suggested that Ayurveda may be effective at reducing the risk of heart disease. For example, one study found that Ayurveda helped reduce plaque and reverse the thickening of artery walls known as atherosclerosis in both healthy adults, as well as adults at high risk for heart disease. Atherosclerosis is a slow, complex disease in which cholesterol, fats, and other substances build up in the inner lining of an artery. This buildup, known as plaque, can lead to heart attack and stroke.

A number of Ayurvedic herbal remedies have been examined, though high-quality studies are lacking. For example, guggul (Commiphora mukul), a traditional Ayurvedic medication used to treat high cholesterol, is widely used in India. It appears to block production of cholesterol in the liver, lowering cholesterol levels. Fenugreek (Trigonella foenum graecum) seeds can lower LDL (bad) cholesterol and triglycerides (fats in the blood), and raise HDL (good) cholesterol levels. Its effects seem to come from its ability to lower the absorption of cholesterol in the intestine, and may be related to the high fiber content of the seed. The high fiber content of fenugreek seeds may also help control blood sugar if you have diabetes.

Most Ayurvedic therapies, such as pranayama and rasayana, are unlikely to have negative side effects in people who are psychologically healthy. People with serious mental health issues may benefit from these therapies. But they should only pursue them under the guidance of a knowledgeable psychiatrist or psychologist.

Ayurvedic herbs may interact with medications. Like all herbs, they are not right for every person. So speak with your physician. In addition, heavy metals such as lead and mercury have contaminated some Ayurvedic herb supplements. Ask your health care provider about choosing quality supplements for you and your family. Be sure to talk to your doctor before trying Ayurveda, especially if you take medicines or have to eat a special diet (to control diabetes, for example).

Although none of the 50 states offer a license to practice Ayurveda, there are several institutions across the U.S. that have educational programs, including The California College of Ayurveda in Grass Valley, California, and the Kerala Ayurveda Academy in Foster City, California. The school issues a certificate of Clinical Ayurvedic Specialist, at www.ayurvedacollege.com. Another sources of information is the Ayurvedic Institute at www.ayurveda.com.

Ayurveda (/ˌɑːjʊərˈveɪdə, -ˈviː-/; IAST: ayurveda)[1] is an alternative medicine system with historical roots in the Indian subcontinent.[2] It is heavily practiced throughout India, Nepal, Bangladesh, Pakistan and Sri Lanka, where as much as 80% of the population report using ayurveda.[3][4][5] The theory and practice of ayurveda is pseudoscientific; some ayurvedic medicines have been found to contain toxic substances.[6][7][8][9]

Ayurveda therapies have varied and evolved over more than two millennia.[2] Therapies include herbal medicines, special diets, meditation, yoga, massage, laxatives, enemas, and medical oils.[10][11] Ayurvedic preparations are typically based on complex herbal compounds, minerals, and metal substances (perhaps under the influence of early Indian alchemy or rasashastra). Ancient ayurveda texts also taught surgical techniques, including rhinoplasty, lithotomy, sutures, cataract surgery, and the extraction of foreign objects.[12][13]

Historical evidence for ayurvedic texts, terminology and concepts appears from the middle of the first millennium BCE onwards.[14] The main classical ayurveda texts begin with accounts of the transmission of medical knowledge from the gods to sages, and then to human physicians.[15] Printed editions of the Sushruta Samhita (Sushruta's Compendium), frame the work as the teachings of Dhanvantari, the Hindu deity of ayurveda, incarnated as King Divodāsa of Varanasi, to a group of physicians, including Sushruta.[16][17] The oldest manuscripts of the work, however, omit this frame, ascribing the work directly to King Divodāsa.[18]

In ayurveda texts, dosha balance is emphasized, and suppressing natural urges is considered unhealthy and claimed to lead to illness.[19] Ayurveda treatises describe three elemental doshas: vāta, pitta and kapha, and state that balance (Skt. sāmyatva) of the doshas results in health, while imbalance (viṣamatva) results in disease. Ayurveda treatises divide medicine into eight canonical components. Ayurveda practitioners had developed various medicinal preparations and surgical procedures from at least the beginning of the common era.[20]

There is no good evidence that ayurveda is effective to treat or cure cancer.[11] Some ayurvedic preparations have been found to contain lead, mercury, and arsenic,[10][22] substances known to be harmful to humans. A 2008 study found the three substances in close to 21% of U.S. and Indian-manufactured patent ayurvedic medicines sold through the Internet.[23] The public health implications of such metallic contaminants in India are unknown.[23]

The earliest classical Sanskrit works on ayurveda describe medicine as being divided into eight components (Skt. aṅga).[28][29] This characterization of the physician's art, "the medicine that has eight components" (Sanskrit: चकत्सयमष्टङ्गयम्, romanized: cikitsāyām aṣṭāṅgāyāṃ), is first found in the Sanskrit epic the Mahābhārata, c. 4th century BCE.[30] The components are:[31][26][32]

The central theoretical ideas of ayurveda show parallels with Samkhya and Vaisheshika philosophies, as well as with Buddhism and Jainism.[34][35] Balance is emphasized, and suppressing natural urges is considered unhealthy and claimed to lead to illness.[19] For example, to suppress sneezing is said to potentially give rise to shoulder pain.[36] However, people are also cautioned to stay within the limits of reasonable balance and measure when following nature's urges.[19] For example, emphasis is placed on moderation of food intake,[37] sleep, and sexual intercourse.[19]

The three postulated elemental bodily humours, the doshas or tridosha, are vata (air, which some modern authors equate with the nervous system), pitta (bile, fire, equated by some with enzymes), and kapha (phlegm, or earth and water, equated by some with mucus). Contemporary critics assert that doshas are not real, but are a fictional concept.[41] The humours (doshas) may also affect mental health. Each dosha has particular attributes and roles within the body and mind; the natural predominance of one or more doshas thus explains a person's physical constitution (prakriti) and personality.[38][42][43] Ayurvedic tradition holds that imbalance among the bodily and mental doshas is a major etiologic component of disease. One ayurvedic view is that the doshas are balanced when they are equal to each other, while another view is that each human possesses a unique combination of the doshas which define this person's temperament and characteristics. In either case, it says that each person should modulate their behavior or environment to increase or decrease the doshas and maintain their natural state. Practitioners of ayurveda must determine an individual's bodily and mental dosha makeup, as certain prakriti are said to predispose one to particular diseases.[44][38] For example, a person who is thin, shy, excitable, has a pronounced Adam's apple, and enjoys esoteric knowledge is likely vata prakriti and therefore more susceptible to conditions such as flatulence, stuttering, and rheumatism.[38][45] Deranged vata is also associated with certain mental disorders due to excited or excess vayu (gas), although the ayurvedic text Charaka Samhita also attributes "insanity" (unmada) to cold food and possession by the ghost of a sinful Brahman (brahmarakshasa).[38][44][46][47]
