Diagnosis

The Physician examines the tongue, complexion, speech, eyes, urine and stools. The interrogation plays only a very minimal role. The siddha methodology of diagnosis is based on the clinical examination of the physician. These diagnostic tools not only help for diagnosis but also to learn the prognosis for the restoration of health.

The siddha methodology of diagnosis is based on the following eight investigations.

1. Tongue (Na):

The tongue is an important indicator. If the tongue is blackish, it indicates a vatha disease, if red, a pitha disease, and if white, a kapha disease.

2. Skin (Mei):

The same inferences as in tongue color.

3. Eye (Vizhi):

Eye discoloration is a critical indication, the color indications as the tongue.

4. Speech (Mozhi):

Speech is another element in diagnosis. The tone, voice and clarity indicates the type of problem.

5. Pulse Examination (Naadi):

This is the most important diagnostic tool of siddha medicine. The pace and tempo of the pulse indicates the type of constitution and the irregularities present in the body. The pulse is examined in the Right hand of males and the left hand for females. The pulse is recorded at the Radial-artery. The unit of pulse diagnosis isĀ 1 for Vatham 1/2 for Pitham and 1/4 for Kapham. This unit is equivalent to the size of a grain (wheat).
