It has 8 ways of diagnosis: Nadi (Pulse), Mootra (Urine), Mala (Stool), Jihva (Tongue), Shabda (Speech), Sparsha (Touch), Druk (Vision), Aakruti (Appearance). Ayurveda stresses the use of plant-based medicines and treatments, such as those derived from roots, leaves, fruits, barks and seeds. Some animal products may also be used like milk, fats, bones, and gallstones. Minerals, including sulphur, arsenic, lead, copper sulfate and gold are also consumed as prescribed.
