The main principles related to health are evaluated in the Greek medicine system. These factors are known as “al-Umur al-Tabiyah”, which is reasonably close to the person’s health. Therefore, an Unani doctor must consider all these principles to determine a person’s disease and its cause. Some of the central tenets of Unani medicine are as follows:
Digestion
According to the Unani system of medicine, there are four different stages of the digestive process. This involves first the stomach’s digestion and then the intestine’s digestion. The food then turns into Chyme and Cal (Chyle), which goes into the liver.
The main four stages of the digestive system are as follows:
- Hepatic digestion: This cal is converted into four different touches of humer (rasikta), called blood, phlegm, yellow bile and black bile.
- Vessel digestion: The tissues in it absorb nutrients with the help of their attractiveness power and retain them with holding power.
- Tissue digestion: It is the process of digestion which works together with other forces to form tissue.
- Expulsive digestion: The expulsive process is considered the end part of the digestive process, in which the remaining waste material is flushed out of the body.
According to Unani physicians, when any defect or function in any stage of the digestive system does not work correctly, various diseases begin to develop.
The State Of The Human Body
According to the Unani medicine, the state of the human body is classified under different headings, which include the following:
Disease: This is opposite to health, in which one or more functions of the body or organs stop working.
Health: In which all the functions and processes of the body work usually.
Neither health nor disease: This is the opposite of both above. Neither the person is ill nor completely healthy—for example, older adults or people who are recovering again after recovering from a disease.
Inner Strength
According to Greek medicine, there are usually three powers: mental (natural) strength, digestive power, and fertility. These three powers are as follows:
- Digestive power: This is the second type of internal strength present in the liver and is active in every body tissue. Metabolism power is usually driven by two different powers, known as nutrient strength and incremental power.
- Fertility: This is the third type of inner strength and is as essential as the above two powers. Reproductive power consists of two forces: productive power and creative power.
- Mental strength is also called nervous or natural power, present in the brain. Mental strength is usually composed of retention power and motivational power.
As per the Unani medicine, the inner forces are an essential part of the body, with the help of which the balance of life is maintained. When any of these strengths are affected, the body cannot function normally, and some health problem develops.
