The Principles of Ayurveda: Dhatus
The word ‘Dhatus‘ originates from the word ‘DHA’ which means foundation or basis. The word ‘Dhatu’ in Sanskrit means “that which binds together”. Dhatus is element. Our body is constructed of Dhatus. The base of survival and growth is Dhatus. For the purpose of maintaining life the Dhatus take various forms in the body. The Dhatus make up various organs and body systems. The Dhatus are the bases of development and nourishment. The mind is supported by Dhatus. The Anatomy and the physiology of the human body are dependent on Dhatus.
According to Ayurveda the seven Dhatus are:
1. Rasa: It is the preliminary Dhatu. It is derived for food digestion. Each and every cell, tissue and part of the body is nourished by Rasa. This is done by circulation of the nutrients. The loss of appetite and other problems are possible if the Rasa is on the increase. Deficiency of Rasa leads to loss of weight, retarded perception of senses, fatigue and dry skin.
2. Rakta : Rakta is also known as blood. It is a fluid connective tissue. It is considered basis of life. Many vital functions of the body are served by Rakta. The Rakta keeps us alive. It provides glow and vigor to the body. It nourishes the intellect and the muscles. Disorder related to Rakta can cause tumors, tiredness, boils, high blood pressure and anemia.
3. Mansa: Mansa strengthens and supports the fat or Meda Dhatu. It is a derivative of blood. It is responsible for providing stamina and physical strength to the body. Disorders in Mansa are expressed as tumors around the neck, face, thigh, abdomen or genitalia.
4. Meda: Meda means the adipose tissue. It acts as the store house of fat. It lubricates the body and provides energy. It insulates the body.
5. Asthi: Asthi means the bone tissue. It forms the skeleton and supports the muscular tissue. Among the connective tissue it is the hardest.
6. Majja: Majja means the yellow and red bone marrow tissue. It is present within the cavities of the bones. It produces the blood cells. It nourishes the semen. Its deficiency may result in sunken eyes and osteoporosis.
7. Shukra: This Dhatu is associated with female and male reproductive system. It is responsible for production of children. The source of Shukra is the Majja.
For perfect health one requires appropriate quantity and quality of each Dhatu and the functioning of these Dhatus should be balanced.
Agni is the Digestive Fire which in modern biological terminology is Enzymes. Agni in other words the enzyme is found in the gastrointestinal track. The gastrointestinal tract is also know and alimentary canal. The alimentary canal digests the food. The three doshas on proper normal digestion result in samagni. The aggravated state of the doshas governs the digestive activity. The digestive activity could be excessive, deficient or healthy. The three agnis produced by the three doshas are Vishamagni (irregular fire), tikshnagni (sharp fire) and mandagni(mild fire)
‘Dosha‘ in Sanskrit means ‘that which maintains and controls the body ‘. The word ‘Tri’ means Three. The Tridoshas are Vata, Pitta and Kapha. The Tridoshas cannot be seen by the naked eye. In this universe particularly in man all the activities are set into three main fundamental functions which are destruction, creation and organization. According to Ayurveda the health is maintained because of the Tridoshas.
“Panch maha bhootas” means 5 basic eternal elements. Every non living being and every living being in this universe is an amalgamation of five basic eternal elements. These five basic elements are
Herbs play a very important role particularly in modern times when the harmful effects of over-medication and food processing have assumed startling proportions. Herbs are generally related to six tastes i.e. sour, salty, sweet, bitter, pungent and astringent. They are now being more and more used in cosmetics, tea and food, as well as alternative medicines.
Even in the history of India, the ayurvedic vaidyas used these medicinal herbs since a very long time. The knowledge of ayurvedic medicines developed amongst the Hindu’s through the four sacred books of Hindu wisdom. The rig-veda, contained the sacred Hindu chants, medicine formulations, description of the surgeries, amputations etc. along with the help of numerous herbs. The ayurvedic vaidyas and the other literates used these herbs in a number of forms like oil, concoctions, paste, filtrate etc. as a treatment for numerous diseases. The oral medicines that were taken are usually in the form of pills or powders which were combined with sugar. Somewhere around in 1200, BCE a literate named Punarvasu Atreya initiated the first medical school in India in the state of Punjab. Later, some seven years after this a professor from this school, named Charaka gathered about 500 distinct herbs and created herbal remedies from them and thus created the Charaka Samhiti which today is considered as one the greatest ayurvedic books. The Hindu herbal medicines mainly are categorized under two main categories.
