Knowing this aim buy imuran master card, one can appreciate the origin of the delicate balance of herbs and spices so characteristic of Indian cuisine buy imuran now. A number of dietary incompatibilities are recognised: milk is 204 | Traditional medicine incompatible with bananas order imuran no prescription, fish with bread, while melons are claimed to be incompatible with most other foods. For hypertension, the instructions might be to drink one cup of mango juice, followed an hour or so later by half a cup of warm milk, a pinch of cardamom and nutmeg, and a teaspoonful of ghee. Cucumber is a diuretic and raita is a yoghurt-based spicy condiment that often features in Indian recipes. Ayurveda prescribes specific diets for several psychiatric disorders and for different drug therapies. It is made by soaking 10 raw almonds in water overnight, then peeling and blending them with a cup of warm milk. Administration of medicines It should be noted that, as with Chinese herbal medicine, the term ‘herbal medicine’ includes animal and mineral products as well as products derived from vegetable sources. In common with other complementary and alterna- tive therapies, the type and dose of medicine chosen are influenced by the individual’s constitution as well as by the nature of the disease. Other factors governing the choice of medicine include the age and strength of the patient, digestive capacity, degree of tolerance and psychological state. There are detailed descriptions of the methods by which medicines should be prepared. One technique, known as samskara (refinement), eliminates the toxicity of the source materials, rather like the aim of serial dilution in homoeopathy. Mixtures of medicines (sumyoga) may be administered to achieve a balanced preparation, one principle balancing another through synergism or antagonism, as with Chinese herbal medicine. The ayurvedic formula chyavanprash combines more than 25 finely powdered herbs in a base of honey and ghee. Plant-based medicines These are used by ayurvedic practitioners in a number of ways, among which are the following examples: • In the treatment of a gastric disturbance in a person exhibiting a pitta prakriti the usual remedies black pepper (Piper rotundum) and ginger (Zingiber officinale) would be administered judiciously or not at all, because they are both considered to increase pitta and may exacerbate the imbalance. This is prescribed for individuals who are Indian ayurvedic medicine | 205 elderly, malnourished, chronically ill or emaciated. The Chinese herb dong quai (Angelica sinensis) is used in the treatment of many gynaecological ailments. This product is rejuvenating and strengthening for all three doshas and all seven dhatus. Triphala comprises three of the most popular ayurvedic herbs: amalaki, bibbitakiu and haritaki. It is normally taken alone, mixed with honey or as a tea an hour after the evening meal. The medicines are supplied as mixtures of herbs in a dried form, or more usually with a suitable vehicle (anupana) to facilitate absorption. People with high cholesterol levels should be wary about taking large amounts of ghee. Only a few local hakims (traditional healers) produced their own remedies, using imported raw materials. Many of these remedies may be purchased over the counter, by mail order through Asian and English language newspapers and the internet, or brought back from visits to the subcontinent. However, finely ground deer horn as a paste may be applied to the thoracic region and is said to be of benefit in angina. The Indian subcontinent has been subject to countless invasions during its history, with diseases being imported from other geographical locations and techniques absorbed from other cultures. For medicinal use metals are traditionally taken internally after under- going rigorous purification to neutralise any toxic effects. Some examples of the medical uses of metals are: • Copper is a good tonic for the liver, spleen and lymphatics. Treatment with aromatherapy Sweet warming aromas such as musk and camphor can balance vata, while pitta is soothed by calming aromas such as sandalwood, jasmine and rose. Kapha is pacified by warming stimulating oils together with pungent oils such as eucalyptus, sage and thyme. Treatment with enema (basti) Basti introduces medicinal remedies, including sesame oil or herbal decoc- tions, in a liquid medium into the rectum. Medicated enemas pacify vata and alleviate many vata disorders, such as constipation, backache, arthritis and various nervous disorders. Indian ayurvedic medicine | 207 Treatment with massage Oil massage (Sanskrit: abhyanga) is an important treatment. While a person may perform massage on his own as part of his daily routine, trained masseurs are required to perform this therapy when it is used for disease management. A massage that is part of the daily routine lasts for 5–15 minutes, but when it is performed for treating diseases it may take about 45 minutes. Nauli is a method of massaging the internal organs, particularly the colon, intestines, liver and spleen. Indian head massage is another specialised form of massage, sometimes known as champissage from its Indian name champi, which is part of the wider ayurvedic medical approach. The head, neck and facial areas are massaged with the purpose of manipulating energy channels. The goal is to clear blocks in these energy channels that cause a build-up of negative energy which are purported to cause ailments. It claims to help stress, insomnia, ridding the body of toxins and promoting hair growth. Interest in ayurvedic massage has been growing in the west with the general trend towards holistic medicines creating a big tourist attraction in the south Indian state of Kerala. The devotees do not say that all commercialism is bad, but they do want ayurveda practised seri- ously, not turned into a side show for tourists. Boards advertising ayurvedic centres are dotted between the tourist cafés and souvenir shops on the beach at Kovalam. Most seem geared towards 1-hour massages, using oils, and most of the tourists here seem to see it as a chance to relax rather than a real medical treatment. Mind–body interventions Colour therapy Ayurvedic treatments make use of colour in their healing procedures. As the colours of the rainbow are perceived as correlating with the body tissues (dhasus) and the doshas, the vibratory energy of the colours may be used to establish psychological harmony and peace of mind. As colour is so impor- tant, patients are told to illuminate themselves and their environment in the appropriate coloured lighting. Treatment with precious and semiprecious stones Gems are thought to have healing properties that can be harnessed by wearing them as jewellery or by placing them in a suitable liquid overnight and drinking the solution. Treatment with meditation Meditation, the art of bringing harmony to body, mind and consciousness, is used to soothe the body and reduce stress. There should be no conscious effort – the mind should be allowed to relax completely (‘float’) as one listens to every sound. Treatment with yoga This is believed to calm the nervous system and balance the body, mind and spirit, as well as provide exercise.
