Chapter 32 Ayurveda
The Science of Life and Mother of the Healing Arts
Introduction
Ayurveda is one of the most ancient systems of medicine known today. The origins of this science of life (Ayu—life and Veda—knowledge), although difficult to pinpoint, have been placed by scholars of ancient Indian Ayurvedic literature somewhere around 6000 BC.1
History
The Development of Ayurvedic Medicine
Hindu legend holds that, after seeing the suffering of human beings, Lord Brahma, the god of creation, elaborated ways to ease that suffering to Daksha, who, in turn, taught them to the Ashwin twins. Figure 32-1 presents the chronology of Ayurveda’s development.
The Major Schools and Specialties
School of Physicians (Atreya Sampradaya)
Charak wrote a complete text on Ayurvedic medicine in which he revised the work of Agnivesh. Charak’s text described the Tridosh physiology (Vat, Pit, and Kaph), seven Dhatus (tissues), and three Malas (excretions). His text covered the pathophysiology and treatment of diseases, human constitution (Prakriti), classifications and preparations of drugs, diet, “right conduct,” medical ethics, and many other aspects of medicine.
Branches of Ayurveda
Ayurveda encompasses eight specialties or branches. They comprise a system developed to prevent and cure disease, as well as achieve and maintain excellent health. Table 32-1 lists the branches.

Philosophy
• The close relationship between humans and the universe (that humans are a microcosm, a universe within themselves, whereas the external environment is the macrocosm).
• The source of all existence is cosmic consciousness, manifest as male (Shiva or Purusha) and female (Shakti or Prakriti) energy.
Five Basic Elements and the Universe (Panchbhuta Philosophy)
The Rishis perceived that consciousness consists of these five basic elements: ether (space), air, fire, water, and earth. At the beginning of the world, consciousness was without form, existing as the subtle vibration of the cosmic “soundless” sound Aum.
Five Elements and the Senses
The five elements also connect with the five senses: ether—hearing, air—touch, fire—vision, water—taste, and earth—smell, and they are present in certain physiologic functions. Expressing the functions of the sensory organs are five actions (Table 32-2). In this manner, the elements are directly related to humans’ abilities both to perceive the external environment in which they live and to respond to it:
• Ether is the medium through which sound travels. The ear is the organ of hearing, expressing its action through the organ of speech, which creates meaningful sound.
• Air is related to skin and the sense of touch. Its organ of action is the hand, which is especially sensitive. The hand performs the actions of holding, giving, and receiving.
• Fire produces light, heat, and color, and is thus related to vision and direction. Its organ is the eye.
• Water relates to the organ of taste. The tongue is also related to the action of the genitals, the penis, and clitoris. In Ayurveda, the penis and clitoris are called the lower tongues. By controlling the upper tongue, one naturally controls the lower tongue.
• The earth element relates to the sense of smell, and the nose is its organ.
