Chapter 36 Asian medicine






HISTORY OF ASIAN MEDICINE SYSTEMS


Many medical systems have emerged from Asia over the centuries, including Unani, Siddha and Ayurveda. When looking in detail at these systems, obvious similarities exist—the main one being the holistic approach each of them takes in treating patients. However, differences arise when one looks at how the development of each system has been affected by non-Asian medical systems over the centuries.



Unani medicine


Unani can be literally translated from the Arabic language as meaning ‘Greek’, from the Arabic word for Greece: ‘al-Yunaan’. As an alternative medicine, Unani has found favour in Asia, especially India. In India, Unani practitioners can practise as qualified doctors, as the Indian government approves their practice. The principles of Unani medicine are based on the teachings of Hippocrates, Galen and Avicenna, and are based on the four humours (elements: phlegm (Balgham), blood (Dam), yellow bile (Safra) and black bile (Sauda). Although the principles of Unani can be traced back to year AD 2 the knowledge and teachings of the medical system were not documented until AD 1025, when Hakim Ibn Sina (known as Avicenna in the West) wrote The Canon of Medicine in Persia. The development of Unani medicine, as documented in this medical encyclopaedia, was influenced by Greek and Islamic medicine, and also by the Indian medical teachings of Sushruta and Charaka, the main texts of Ayurvedic medicine; both systems are based on the theory of the presence of elements in the human body, and the balance of these elements determines the state of a person’s health. Each person’s unique mixture of these substances determines his or her temperament: a predominance of blood gives a sanguine temperament; a predominance of phlegm makes one phlegmatic; yellow bile, bilious (or choleric); and black bile, melancholic. In Unani medicine, many medicines are based on honey, which is considered to have healing properties. Real pearls and metal are also used in the making of Unani medicine based on the kind of ailment it is aimed to heal. In today’s modern medical world, honey is often used in wound dressings to kill bacteria because the high sugar content causes movement of water from inside bacterial cells by osmosis, leading to massive dehydration and the eventual death of the infecting organisms.



Ayurveda


Ayurveda is the ancient and sacred (Hindu) system of health care, originating in India over 5000 years ago. It is purely Indian in origin and has not been influenced by other countries or their medical systems. The literal translation of the word ‘Ayurveda’ from two words in Sanskrit—āyus, meaning ‘life principle’ and veda, referring to a ‘system of knowledge’—accurately portrays the complexity and depth into which this medical system goes. A more overreaching translation can be taken as ‘The knowledge (or science) of life’. The Charaka Samhita—an ancient Indian Ayurvedic text on internal medicine defines ‘life’ as a ‘combination of the body, sense organs, mind and soul, the factor responsible for preventing decay and death, which sustains the body over time, and guides the processes of rebirth’ and is one of the earliest written texts of Ayurveda, dating back to about 300 BC (see Chattopadhyaya, Further reading). It is believed to be the oldest of three ancient treatises of Ayurveda and is central to the modern-day practice of Ayurvedic medicine. Ayurveda is concerned with measures to protect ‘āyus’, which includes healthy living along with therapeutic measures that relate to physical, mental, social and spiritual harmony. It is also one among the few traditional systems of medicine to contain a sophisticated system of surgery (which is referred to as ‘salya-chikitsa’). In today’s Western society, theemergence of holistic health systems such as Ayurveda has led to the accommodation of modern science, especially in relation to the testing of medicines, in which research and adaptation are actively encouraged. Indeed, it is perfectly possible to evaluate Ayurvedic medicines using conventional clinical trials, and this is being carried out increasingly. At present, there are only a few Ayurvedic practitioners (‘vaid’) in the West, but the rapidly increasing popularity of more holistic approaches to health—where each patient is considered unique and therefore must be treated individually—has led to the emergence of schools of Ayurveda, Ayurvedic treatment centres and more Ayurvedic medicines being imported. This approach is in contrast to Western medicine where populations are generalized and ‘normal’ means what is applicable to the majority. Many ethnic populations from India and Pakistan continue to use their own traditional remedies while living in Europe, Australia or the US. Philosophically, Ayurveda has similarities with Traditional Chinese Medicine (TCM). The familiar yin and yang—the opposing life forces identified in TCM, can be likened to the three ‘humours’ of Ayurveda—the tridosha.



Siddha medicine


Siddha, from the Tamil word for ‘achievements’, is said to have been developed by eighteen siddhars (beings who have achieved a high degree of physical as well as spiritual perfection or enlightenment), led by the great Siddha Ayastiyar. Some of his works are still standard books of medicine and surgery in daily use among the Siddha medical practitioners of today. Siddha literature is written in Tamil and the medicine is practised largely in Tamil-speaking parts of India and abroad. Like Ayurvedic medicine, this system believes that all objects in the universe, including the human body, are composed of five basic elements: earth, water, fire, air and sky. Siddha medicine is largely therapeutic in nature, and is a form of treatment of disease using substances of all possible origins in a way that balances the possible harmful effects of each substance. The principles and doctrines of this system, both fundamental and applied, have a close similarity to Ayurveda. Additionally, this system also considers the human body as a conglomeration of three humours, seven basic tissues and the waste products of the body. As in both Unani and Ayurvedic medical systems, the equilibrium of humours is considered as a healthy state, and its disturbance or imbalance leads to disease or sickness. Ancient siddhars wrote their recipes on palm-leaves for the use of future generations, and details include preparations that are made mainly out of the parts of the plants and trees, such as leaves, bark, stem, root, etc., but also include mineral and some animal substances. The use of metals like gold, silver and iron powders in some preparations is a special feature of Siddha medicine, which claims it can detoxify metals to enable them to be used for stubborn diseases. The use of mercury in the Siddha medical system is well documented and not uncommon, so patients prescribed medicines containing purified mercury should be treated only by highly qualified practitioners of the art. Over the centuries, the system has developed a rich and unique treasure of drug knowledge in which use of metals and minerals is very much advocated. The depth of knowledge required by practitioners of Siddha medicine is summarized below:









Most medicines and remedies (often common herbs and foods) used in Unani medicine (and Siddha medicine to a lesser extent) are also used in Ayurveda. Whereas Unani was influenced by Islam and Siddha by Alchemy, Ayurveda is associated with Vedic culture, and is generally considered to be the most ‘original’ form of traditional Asian medicine. The Materia medica of all these medical systems consists of many herbs made into pills, syrups, confections and alcoholic extracts, and also some metals. These traditional systems are still practised in rural communities in India and Pakistan—much more so than in cities.
