== General rules with exceptions regarding the determination of veerya (veerya nirdhaarana samanya siddhaanta and apavada) ==

−

[[Ayurveda|Ayurveda]] has termed the general rules regarding the relation and determining veerya of any [[Dravya|dravya]] based on its [[Rasa|rasa (taste)]] and [[Vipaka|vipaka]] (post digestive effect). This can be equated to the basis of the panchabhautika constitution of the [[Dravya|dravya]]. However, this rule has a few exceptions due to the variable panchabhautika configuration. More research studies can be carried out to further validate these concepts. The general rule states that a substance of ~~madhura  rasa~~ (sweet in taste) ~~and madhura~~ [[Vipaka|vipaka]] most commonly possesses [[Sheeta|sheeta]] veerya. The sour substance (amla) in [[Rasa|rasa]] and [[Vipaka|vipaka]] is generally hot (ushna) in veerya. Similarly, [[Dravya|dravya]] with pungent (katu) [[Rasa|rasa]] and [[Vipaka|vipaka]] is hot (ushna) in veerya. [Cha.Sa. [[Sutra Sthana|Sutra Sthana]] 26/45] In this category usually by assessing [[Rasa|rasa]] of a [[Dravya|dravya]] (rasa-upadeshena), one can conclude the veerya of that particular [[Dravya|dravya]]. [Cha.Sa. [[Sutra Sthana|Sutra Sthana]] 26/46] Thus, the variation in [[Vipaka|vipaka]] or veerya of a [[Dravya|dravya]] can result in variation of its [[Karma|karma]] and [[Guna|guna]] (properties) despite the quality of [[Rasa|rasa]]. [Cha.Sa. [[Sutra Sthana|Sutra Sthana]] 26/46] The following table the general rule and the exception with examples are mentioned as below:

== Superiority of veerya ==

−

Principles of drug action in [[Ayurveda|ayurveda]] can be summarized in case of equality of strength. [[Vipaka|Vipaka]] overpowers rasa, veerya overpowers rasa. [[Vipaka|Vipaka]] and [[Prabhava|prabhava]] are considered to be competitive among all these three. [Cha.Sa. [[Sutra Sthana|Sutra Sthana]] .26/68-72] [A.H. [[Sutra Sthana|Sutra Sthana]] 9/25] These factors act by overpowering and defeating one another. For instance, the hot potency (ushna veerya) of buffalo meat (mahisha mamsa) dominates the sweet taste and sweet post-digestive effect leading to the vitiation of [[Pitta dosha|pitta dosha]]. [Arundatta on A.H. [[Sutra Sthana|Sutra Sthana]] 9/25] When there is a combination of antagonistic characteristics (viruddha guna), the dominant factor will overpower the weak one (Bhuyasa Alpam Avajiyate) [Cha.Sa.Vimana Sthana 1/14] For instance, the guru, snigdha guna of milk (ksheera) dominates over its [[Sheeta|sheeta]] veerya resulting in vata shamana. [Arundatta on A.H. [[Sutra Sthana|Sutra Sthana]] 9/24]

== Concept of veerya viruddha (contradictory potencies) ==

−

Veerya viruddha is listed as one of the types amongst 18 types of viruddha aahara. [Cha.Sa. [[Sutra Sthana|Sutra Sthana]] 26/86-87] Consumption of [[Sheeta|sheeta]] veerya dravya in combination with ushna veerya dravya is stated as the example of veerya viruddha. [Cha.Sa.[[Sutra Sthana|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]

== Importance of concept of veerya ==

−

Veerya is an important factor determining the action of any [[Dravya|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|sheeta]] veerya. Thus it becomes an important factor in mentioning the qualities of any [[Aushadha|medicine (aushadha)]] or food ([[Ahara|aahara]]) dravya. The veerya of dravya is mentioned while depicting the action of that particular dravya. For instance, the [[Sheeta|sheeta]] veerya of ghee (ghrita) is responsible for the pacifying [[Pitta dosha|pitta]] (shamana) action, especially in fever (jwara) [Cha.Sa.Nidan Sthana1/39] Thus it constitutes the most important factor for administrating any [[Dravya|dravya]] in the body. The dominance of veerya enhances the activity of any particular [[Dravya|dravya]]. The pharmaceutical processes like bhavana (lavation), kala sanskara (time), samyoga (combination with other herbs) may help enhance the potency of herbs.

<li style="font-weight:bold">Study of action of ushna and [[Sheeta|sheeta]] veerya drugs on skeletal muscle The aqueous extracts (10% water infusion) total of 24 drugs, with 12 each belonging to ushna and [[Sheeta|sheeta]] veerya were tested for their activity against contractions of frog skeletal muscle (frog rectus abdominis) by using Burn model (1954)<ref name="ref16">Periasamy A, Burns DH, Holdren DN, Pollack GH, Trombitas K. A-band shortening in single fibers of frog skeletal muscle. Biophysical journal. 1990 Apr 1;57(4):815-28.</ref>. However, statistical analysis showed insignificant inhibition of both the veeryas. Therefore, the skeletal muscle experiment does not reveal any specificity about the nature of veerya.2 </li>

<li style="font-weight:bold">Effect of ushna and [[Sheeta|sheeta]] veerya drugs on the frog heart muscle The aqueous extracts if 16 ushna and 16 sheeta veerya drugs were screened on 32 healthy frog hearts. The effect of ushna and [[Sheeta|sheeta]] veerya drugs in different doses (0.2 ml and 0.4 ml) was assessed on the basis of heart rate (chronotropic activity) and amplitude (Inotropic) activity of isolated frog heart during and after perfusion).2 More depressant effect on amplitude was exercised by ushna veerya group in comparison with [[Sheeta|sheeta]] veerya group. Both [[Sheeta|sheeta]] and ushna veerya drugs showed an insignificant decrease in heart rate. Hence, the action of ushna and sheeta veerya drugs cannot be associated with positive and negative chronotropic and ionotropic effect since both the groups have not shown a specific action on frog heart rate and amplitude (NishteswarK.et.al.)2 </li>

<li style="font-weight:bold">Effect of [[Sheeta|sheeta]] and ushna veerya drugs on basic metabolic rate (B.M.R.) Two [[Sheeta|sheeta]] veerya drugs namely yashtimadhu (Glycyrrhiza glabra) and shatavari (Asparagus racemosus) and two ushna veerya drugs namely chitraka (Plumbago zeylanica) and jaatiphala (Myristica fragrans) were studied. In healthy volunteers initially B.M.R. was recorded2 and the drug was administrated three times for one day. A significant increase (P<0.05) was observed with yashtimadhu, while increase in B.M.R. with shatavari was insignificant. Ushna veerya drugs brought about a decrease in B.M.R. after administration. Both chitraka and jaatiphala showed very significant action (P<0.05). Therefore, [[Sheeta|sheeta]] and ushna Veerya, which represent the saumyatva and agneyatva of a drug or food, may be responsible for synthesizing or metabolizing the [[Dhatu|dhatu]] due to their santarpana or apatarpana actions.

Then the sample was kept on water bath for 30 minutes and again pH was recorded.2 All the screened drugs showed acidic reaction and it was evident from the present study that ushna and [[Sheeta|sheeta]] veerya drugs do not exhibit specific difference in pH values.
