The Unani system of medicine owes, as its name suggests, its origin to Greece. The term “UNANI” is derived from the word “UNAN” which means Greece in Arabic. It was the work of the Greek philosopher-physician Hippocrates {Buqrat In Arabic} (460-377 B.C.), who freed medicine from the realm of superstition and magic and gave it the status of science. He considered illness to be natural rather than a supernatural phenomenon, and he felt that medicines should be administered without ritual ceremonies or magic. The theoretical framework of Unani System is based on the teachings of Hippocrates. By his method of careful study and comparison of symptoms, he laid the foundation for clinical Herbal Medicines.

After Hippocrates a number of other Greek scholars enriched the system considerably. Of them Galen {Jalinus in Arabic} (131-200 A.D.) stands out as the one who established its foundation on which Arab physicians like Rhazes {Al-Razi in Arabic} (850-932 A.D.) and Avicenna {Ibn-Sena in Arabic} (980-1037 A.D.) constructed an imposing edifice. Galen introduced and practiced the Unani system of Herbal Supplements in pre-Islamic Egypt, serving as Royal court physician to the King of Egypt and under his patronage, researched, experimented and developed hundreds of new Herbal formulations and cures for almost all types of diseases.

Imbibing what was best in the contemporary systems of traditional Herbal System in Egypt, Syria, Iraq, Persia, India, China and other Middle East and Far East countries enriched the Unani system. That is why this system is known, in different parts of the world, with different names such as Greco-Arab Medicine or ”Unani Tibb”, Ionian Herbal Medicine, Arab Herbal Medicine, Islamic Herbal Medicine, Traditional Herbal Medicine, Oriental Herbal Medicine, etc.

In India

In India, Unani system of Medicine was introduced by the Arabs and soon took firm roots in the soil. When Mongols ravaged Persian and Central Asian cities, scholars and physicians of Unani Herbal Supplements fled to India. The Delhi Sultans, the Khiljis, the Tughlaqs and the Mughal Emperors provided state patronage to the scholars and even enrolled some as state employees and court physicians. During 13th and 17th century A.D. Unani Herbal Supplements had its heyday in India. During the British rule Unani system of Herbal Supplements suffered a setback due to withdrawal of State patronage, but continued to be practiced as the masses reposed faith in the system. An outstanding physician and scholar of Unani Medicine, Hakim Ajmal Khan (1868 – 1927), championed the cause of the system in India.

Fundamentals
According to the principles and philosophy of Unani System, disease is a natural process, its symptoms are the reaction of the body to the disease, and the chief function of the physician is to aid the natural forces of the theory. Unani System is basically based on Humoral Theory.

The Humors (Akhlat)
According to Unani system of Medicine, diseases are natural processes and the symptoms are body’s reaction to them. Human body has self-preservation power (Quwwat-e-Mudabbira) that maintains the balance of the 4 humours. Unani treatment facilitates body to regain or strengthen this balance. It follows the humoural theory that postulates presence of four humours in the body namely, Dam (blood), Balgham (phlegm), Safra (yellow bile) and Sauda (black bile). The temperaments of persons are expressed by the words sanguine, phlegmatic, choleric and melancholic according to the preponderance in them of humors — blood, phlegm, yellow bile and black bile, respectively. The humors themselves are assigned temperaments — blood is hot and moist, phlegm is cold and moist, yellow bile is hot and dry, and black bile is cold and moist. Every person is supposed to have a unique humoral constitution which represents his healthy state. As long as these humors exist in normal balance, normal quantities and in the normal region of the body, the humor system will work in the normal way. Any imbalances to the humor constitutions or changes in their quantity and quality result in diseases. To maintain the correct humoral balance there is a power of self- preservation or adjustment called Quwwat-e-Mudabbira (medicatrix naturae) in the body. If this power weakens, imbalance in the humoral composition is bound to occur which causes disease. In Unani Herbal Supplements, great reliance is placed on this power. Unani System used in this system, in fact, help the body to regain this power to an optimum level and thereby restore humoral balance, thus restoring health. Also, correct diet and digestion are considered necessary to maintain humoral balance.

Another distinctive feature of the Unani system of Herbal Supplements is its emphasis on diagnosing a disease through Nabz (pulse), a rhythmic expansion of arteries which is felt by fingers. The reading of the pulse permits a rather straightforward assessment of several factors: 1) which humor is out of balance; 2) what is the nature of the imbalance; that is, excess of heat or coldness, wetness or dryness; and 3) which of the primary organs are effected. Other methods of diagnosis include examination of Baul (urine), Baraz (stool), etc.

Prevention of Disease
Unani system of medicine recognises the influence of surroundings and ecological conditions on the state of health of human beings. The system aims at restoring the equilibrium of various elements and faculties of the human body. It has laid down six essential prerequisites for the prevention of diseases and places great emphasis on the maintenance of proper ecological balance and on keeping water, food and air free from pollution. These essentials, known as “Asbab-e-Sitta Zarooriya”, are air, food and drinks, bodily movement and repose, psychic movement and response, sleep and wakefulness, and excretion and retention.

Types of Treatment
Unani system has various modes of treating an ailment depending upon the nature of the ailment and its causes, such as Ilaj-bil-Tadbeer (Regimental therapy), Ilaj-bil-Ghiza (Dietotherapy), Ilaj-bil-Dawa (Pharmacotherapy) and Ilaj-bil-Yad (Surgery).

The weakness of certain organs is corrected by administering the same organ of an animal by way of food; for instance, disorders and weakness of liver are treated by feeding the patient on liver. Likewise heart, kidneys and brain are administered in treating the ailments of these parts. Sometimes, the patient is even asked to forego food altogether.
