==Importance of deepana==
Digestive fire (Agni) is one of the most important concepts in Ayurveda. A qualitative or quantitative reduction in the digestive fire is considered as the cause for all diseases.[A.Hr.Nidana Sthana.12/1]<ref name=Hridaya/> Maintaining the digestive fire in its normal level is essential to maintain health. Deepana helps to kindle the digestive fire.
The deepana property is attributed to a wide range of drugs, food materials and even some of the regimens also. Among them the best material which increases the digestive fire is fats/oils (sneha) [Cha.Sa.[[Chikitsa Sthana]] 15/201]. The drugs which possess the deepana property is having the predominance of [[Agni mahabhuta]].[Su.Sa.Sutra Sthana.41/6]<ref name= Susruta> Sushruta. Sushruta Samhita. Edited by Jadavaji Trikamji Aacharya. 8th ed. Varanasi: Chaukhambha Orientalia;2005.</ref>
*The tastes (rasa) which have deepana property : Salt (lavana), Bitter (tikta) [Cha.Sa.[[Sutra Sthana]] 26/43], Spicy (katu) [Su.Sa.Sutra Sthana.42/10]<ref name=Susruta/>
*Drugs which possess deepana property: Anethum sowa(shatapushpa), Tinospora cordifolia (guduchi), Azadirachta indica(nimbi), Sentalum album(chandana), Prunus cerasoides(padmaka), Piper longum(pippali), Piper nigrum(maricha), Zingiber officinale(sunti),Aegle marmelos(bilwa), Clerodendrum phlomidis(agnimanda), Cyperus rotundus(musta), Terminalia chebula(haritaki) etc.
*Food items which possess deepana property: Hot water [Su.Sa.Sutra Sthana.45/39]<ref name=Susruta/>, coconut water [Su.Sa.Sutra Sthana.45/43]<ref name=Susruta/>, cow’s milk <ref name=Susruta/>, breast milk[Su.Sa.Sutra Sthana.45/57]<ref name=Susruta/>, buttermilk, alcohol, honey, salt, asafoetida etc.
*Regimen which possess deepana property: Bath [A.Hr.Sutra Sthana.2/16] <ref name=Hridaya/>
==Importance in preservation of health and prevention==
In rainy season the digestive fire is naturally less because of the effect of season and there is aggravation of all the doshas. So the person should follow the diet and drugs which have deepana property in order to prevent the occurrence of diseases. [Su.Sa.Uttaratantra.64/7]<ref name=Susruta/>
==Importance in management of disease==
Deepana is indicated in large number of diseases. Few examples are the following
*in the treatment of fever (jwara) with hotwater [Cha.Sa.[[Chikitsa Sthana]] 3/144]
*in [[kapha]] gulma with buttermilk (takra) [Cha.Sa.[[Chikitsa Sthana]] 8/119]
*in grahani roga with buttermilk [Cha.Sa.[[Chikitsa Sthana]] 15/117]. Deepana is always indicated in all types of grahani disease.[Su.Sa.Uttaratantra.40/182]<ref name=Susruta/>
*for patients of tuberculosis (rajayakshma) suffering from bouts of diarrhea (atisara). [Cha.Sa.[[Chikitsa Sthana]] 8/134]
*for the removal of distaste in the mouth.[Cha.Sa.[[Chikitsa Sthana]] 8/136]
for the treatment of debility due to injury(kshatakheena).[Cha.Sa.[[Chikitsa Sthana]] 11/84]
*for the treatment of piles/hemorrhoids (arsha). [Cha.Sa.[[Chikitsa Sthana]] 14/250]
*for the treatment of [[ama]] which gets stuck inside the intestine (pakvasaya) [Cha.Sa.[[Chikitsa Sthana]] 15/75]
*in the beginning stages of kshayaja kasa [Cha.Sa.[[Chikitsa Sthana]] 18/150]
*[[vata]] lodged in the alimentary tract.[Cha.Sa.[[Chikitsa Sthana]] 28/89]
*If [[vata]] is occluded by food (annavruta vata) [Cha.Sa.[[Chikitsa Sthana]] 28/196]
*Occlusion of apana by samana [Cha.Sa.[[Chikitsa Sthana]] 28/206]
*Occlusion of udana by apana[Cha.Sa.[[Chikitsa Sthana]] 28/211]
*For the treatment of distension of abdomen(admana) [Su.Sa.Chikitsa Sthana.5/26]<ref name=Susruta/>
The medicines should be administered along with the food in order to attain the deepana effect. [Su.Sa.Uttaratantra.64/75]<ref name=Susruta/>
==As a prerequisite for purification therapy==
Before purificatory therapies digestive(pachana), deepana, oleation and sudation therapies should be performed. Through deepana the doshas gets detached from the body tissues or body channels [Hemadri on A.Hr Sutra Sthana 13/29]<ref name=Hridaya/> and thus facilitates an easy, effective and safe purification therapy.
==After the purification therapy==
After the purification procedures, the power of the digestive fire diminishes. To bring back the digestive fire to its normalcy the diet plan which has deepana property should be advised. In case of bloodletting also after the procedure, the need to protect the digestive fire is highlighted. [A.Hr.Sutra Sthana.27/52]<ref name=Hridaya/>
Some of the medicines with deepana property
*Taleesadi churna [Cha.Sa.[[Chikitsa Sthana]] 8/146]
*Takrarishta [Cha.Sa.[[Chikitsa Sthana]] 14/75]
*Pippalyadi gritha [Cha.Sa.[[Chikitsa Sthana]] 14/118]
*Dantyarishta [Cha.Sa.[[Chikitsa Sthana]] 14/147]
*Dadimadi gritha [Cha.Sa.[[Chikitsa Sthana]] 16/46]

==Current researches==
Ghrelin is an orexigenic hormone secreted from the stomach. The concentration of ghrelin in plasma has been reported to rise before food intake and it falls after the ingestion of food. While administered peripherally there was an increase in food intake and it also activates a group of neurons in hypothalamus called AgRP(agoutirelated peptide) neurons. Asprosin is another orexigenic hormone that activates AgRP directly.
In animal studies, it is observed that AgRP neurons become activated when there is deficiency in calories and becomes less active when they are fed. In already fed animals when the AgRP neurons were activated through chemical or light stimulus they start to eat intensely. So these neurons are considered as hunger promoting neurons.<ref>L R Beutler, Z A Knight. A spotlight on appetite. Neuron. 2018 February 21; 97(4): 739–741. doi:10.1016/j.neuron.2018.01.050</ref>
Leptin is an anorexigenic hormone secreted by adipose tissue. Its main function is to maintain adequate fat storage in body. A fall in leptin level stimulates hunger.<ref>M L Andermann, B B Lowell. Towards a wiring-diagram understanding of appetite control. Neuron. 2017 August 16; 95(4): 757–778. doi:10.1016/j.neuron.2017.06.014.</ref>
The mode of action of deepana drugs is still unclear. More research works are needed in this regard to show whether deepana is having any action over hormones, neurons etc.
