Among 110 plants in medicine preparation, 34 uses root, 18 uses seeds, 12 uses leaves, 10 are rhizomes other parts used are comparatively less. In Suvai 50 are bitter, 35 pungent, 18 astringent and 20 sweet. In which some of the plant parts has two tastes. In Veeriyam 77 are hot in potency and 33 are cold in potency. On seeing Vipakam 86 shows pungent and 24 shows sweet. According to Siddha fundamental, respiratory disorders are due to increases of Kapha. Kapha is Guru, cold in character which has Pruthvi and Appupanchapootha, so hot in character should be given for treatment, accordingly literature review says, in prepared medicines, most of the ingredients are hot in potency and has pungent Vipaka which has Vayu and the Vayupanchapootham and Laghu in character.
