== Concept of veerya in the context of pharmaceutics ==
The intactness of veerya or efficacy is also termed as ‘shelf life’ of different pharmaceutical preparations. This concept was described by Sharangdhara<ref name="ref13">Sharangdhar, Sharangdhar Samhita, Paribhasha Prakarana, Prathama khanda, 1/51-53, sixted edition 2016, Chaukhamba Orientalia , Varanasi , Page No. 8</ref> in his paribhasha as follows-

== Concept of veerya viruddha (contradictory potencies) ==
 +
<p style='text-align:justify;'>Veerya viruddha is listed as one of the types amongst 18 types of viruddha aahara. [Cha.Sa. Sutra Sthana 26/86-87] Consumption of sheeta veerya dravya in combination with ushna veerya dravya is stated as the example of veerya viruddha. [Cha.Sa.Sutra Sthana 26/92] For instance, milk consumption of cold potency and fish of hot potency are contradictory. The dietary guidelines (aahar vidhi Vidhana) advise avoiding the consumption of veerya viruddha as it can result in occurrence of several diseases [Cha.Sa.Viman Sthana1/24] </p>

== Importance of concept of veerya ==
 +
<p style='text-align:justify;'>Veerya is an important factor determining the action of any dravya. The duality of action in the form of catabolism or anabolism is well understood by the two types (dwividha veerya) i.e. ushna and sheeta veerya. Thus it becomes an important factor in mentioning the qualities of any medicine (aushadha) or food (aahara) dravya. The veerya of dravya is mentioned while depicting the action of that particular dravya. For instance, the sheeta veerya of ghee (ghrita) is responsible for the pacifying pitta (shamana) action, especially in fever (jwara) [Cha.Sa.Nidan Sthana1/39] Thus it constitutes the most important factor for administrating any dravya in the body. The dominance of veerya enhances the activity of any particular dravya. The pharmaceutical processes like bhavana (lavation), kala sanskara (time), samyoga (combination with other herbs) may help enhance the potency of herbs.</p>

<p style='text-align:justify;'>Veerya is the subject of extensive research, especially considering the ayurveda pharmacology. Dr. Nisteshwar K. has conducted a few animal experiments to establish the scientific validity of concept of veerya.<ref name="ref15">Nishteswar K, Basic concepts of Ayurvedic pharmacology , Chowkamba Sanskrit Series Office, Varanasi.
