Ama is a state of or products formed due to incomplete digestion, metabolism, or transformation. [[Agni|Agni]] (digestion and metabolism) is a factor responsible for changing the state of a substance. In human biology, the digestion and metabolic processes convert food and other substances into compatible and nourishing body components. If these processes are incomplete, poor or slow, then the final products formed are of poor quality. [[Agni|Agni]] is one of the most important factors responsible for [[Health|health]] (prakrita) abnormalities, and diseases ([[Vikriti|vikriti]]). [[Ayu|Life span]], strength, [[Health|health]], and immunity all depends on [[Agni|agni]]. [Cha. Sa. Chikitsa Sthana 15/03] If [[Agni|agni]] is disturbed, then proper digestion does not occur which results in improperly transformed food/metabolites are termed as ‘Ama’. [A. H. Sutra Sthana 13/25] The concept of ama in ayurveda is very important in pathogenesis of disease. One of the synonyms of vyadhi (disease) is “aamaya” which means caused by ama. [Cha. Sa. Nidana Sthana 1/05] Classification of stages of diseases (vyadhi) is based on the presence and absence of ama i.e., sa-ama avastha (stage associated with ama) and nirama avastha (stage not associated with ama). The treatment protocol also depends on stages of ama such as in diarrhoea associated with ama(ama-atisara), styptic therapy (stambhana) is contraindicated. Whereas, in the diarrhoea without ama (nirama stage) / or chronic diarrhoea (jeerna atisara), styptinc therapy (stambhana) is advised. Thus, concept of ama is significant in understanding the etiopathogenesis, diagnosis as well as treatment of diseases. This chapter describes concept of ama with its contemporary views and researches done on it.

== Diseases caused by ama ==

−

The undigested food gets fermented (shuktata) leading to onset of toxic symptoms. [Cha. Sa. Chikitsa Sthana 15/42-44] Ama further leads to various digestive disorders like amajirna (indigestion due to saama pitta), vishtabdhajirna (indigestion due to saama vata), vidagdha ajirna (indigestion due to saama kapha), visuchika (non-infectious gastroenteritis), alasaka (sluggish bowels), vilambika (gastro-intestinal stasis). [Su. Sa. Uttara Sthana 56/3] The diseases caused by ama at various dhatu level are jwara (fever), atisara (diarrhoea), pravahika (dysentery), etc. The chronic conditions caused by ama are such as grahini-dosha (functional impairment of agni), udara roga (ascites and abdominal enlargement), yakrit vyadhi (liver disorders), jalodara (ascites), shotha (oedema), pandu (anemia), prameha (obstinate urinary disease), amavata (rheumatism), etc.

The acidic nature (amla bhava) of undigested food (apakva anna) is called as suktata (acidic /sour nature of undigested food) which further acts like a visha (poison) that will further produce number of other diseases, so this can be compared to symptoms of amavisha.<ref name="ref3">Chakrapani.

When ama combines with pitta dosha, it produces pitta dominant diseases such as burning sensation (daha), thirst (pipasa), diseases of oral cavity (mukha roga), hyperacidity (amlapitta) etc. When it combines with kapha dosha, it produces kapha dominant diseases such as rajayakshma (consumption), pinasa (chronic rhinitis), prameha (obstinate urinary disease), etc. When combines with vata dosha, it produces different types of vata dominant diseases. When combines with mutra (urine) or gets lodged in mutravaha srotasa (urinary tract), to produce mutra roga such as mutrakrichhra (dysuria), mutraghata (urinary retention), prameha (obstinate urinary disease), etc. When combines with purisha (feces) produces diseases of kukshi (pelvis) or udara roga (diseases of abdomen). When combines with rasa etc. dhatu (seven major structural components of the body), then produces their respective diseases.

== Characteristics of ama ==

−

Ama possesses characteristics such as liquid (drava), heavy (guru), attains different colors, slimy (snigdha), viscid (pichchila), thready (tantumatva), foul smelling (durgandhi). Ama is etiological factor of all diseases and produces symptoms such as various types of pain (shoola), obstructs channels (srotorodhaka), undigested (avipakva), lethargic (sadanakaraka), etc.<ref name="ref4">Arundatta.

== Clinical presentations due to ama ==

There are mainly two types of ama dosha or ama dosha vikara (disease) viz; visuchika (non-infectious gastroenteritis /choleretic diarrhoea) and alasaka (sluggish bowel/intestinal obstruction). [Cha. Sa. Vimana Sthana. 2/10] Food taken in excessive quantity is the cause for sudden aggravation of all three dosha and formation of ama. All aggravated three dosha combine with ama and produce diseases like alasaka and visuchika. [A. H. Sutra Sthana. 8/5-12]

<ol style='text-align:justify;'><li style="font-weight:bold">Visuchika (gastro-enteritis): The word visuchika derived from “suchi” means needle or “suchi vidh vedana” (pricking pain). The expulsion of ama dosha (undigested food) through both upper and lower passages of the gastrointestinal tract is called visuchika (non-infectious gastroenteritis). The doshas when tend to move outwards from both upper and downwards routes means both vomiting and diarrhoea occurs simultaneously. Due to aggravation of vata and other doshas different types of pain occur as the patients feels as if his body is being pricked by needles (suchi) so the disease is named visuchika. It can be compared with gastro-enteritis due to pathogens such as Cholera bacilli. Complications caused by visuchika are, abdominal colic, vertigo, abdominal distension, tremors and rigidity by vata dosha. Pitta causes jwara (fever), atisara (diarrhoea), burning sensation within body, thirst, fainting and drowsiness. Kapha dosha leads to chardi (vomiting), heaviness of the body, unable to speak, excessive salivation and cough. </li>

<li style="font-weight:bold">Alasaka (sluggish bowels): The word Alasaka derived from word “Alasa” means no movement. When frail person having weak digestive power and excess of kapha in the body, it habitually suppresses the urges of passing flatulence, micturition and bowels and at the same time consumes sthira (solid), guru (heavy), atishushka (excessively dry), and sheeta (cold), in excessive quantities then his ingested food gets afflicted by vayu (vata dosha). Even exerting pressure does not push the undigested food out of the passage since it is obstructed by kapha, by excreta accumulated already, and also because of sluggish nature caused by all these factors. Vishtambhan (stasis) of dosha occurs so the ama remains/stagnated within the stomach i.e., food neither passes upwards nor downward. This condition is called alasaka. All the characteristic features of ama dosha, except vomiting and diarrhoea, are manifested severely in alasaka. This can be compared with Cholera sicca where, the entire body fluids are dragged into the intestines and intestines gets paralyzed and the patients dies because of tissue dehydration. Aggravated vata dosha vitiates the consumed food and kapha dosha obstructs the channels. The undigested food remains in gut without any further process. It causes irritation and colicky pain without vomiting or diarrhoea. </li></ol>

'''Dandaka alasaka''' (delayed and obstructive digestive process wherein body becomes stiff like a stick):

−

Severely vitiated dosha associated with ama spreads all over the channels of body and spreads throughout the body. The extremely vitiated dosha move obliquely towards other body channels to block them. As all body channels are blocked by ama, the body becomes rigid like wooden rod/staff (danda). This condition is critical and needs urgent medical care. Such clinical condition is known as dandalasaka/ dandaka alasaka.

The apatarpana is of three types viz., langhana (fasting), langhana- pachana and dosha avasechana (shodhana). Based on the avastha of dosha the type of apatarpana is to be advised i.e., in low grade (alpa) dosha stage, langhana (fasting) as it stimulates the digestive process by predominance of [[Agni|agni]] (fire element) and vayu (air element) mahabhuta. In moderate grade (madhyama) dosha stage, langhana and pachana (fasting with digestant) should be adopted.

In recent years, the concept of free radical theory of oxidative damage in human diseases is accepted widely. Free radicals consist of an atom or molecule which have an unpaired electron. The tendency of such atom to gain an electron from other substances makes it highly reactive species to have a high capacity to oxidize biological molecules such as lipids, nucleic acids, proteins, etc. During the disease process, infections, toxins and trauma, these free radicals get released in body and cause diseases. Free radicals play a significant role in some of the diseases like rheumatoid arthritis, inflammatory gut disorder like ulcerative colitis, diseases of connective tissue, atherosclerosis, myocardial infarction, stroke, cancer, parkinsonism, Alzheimer’s, dementia, diabetes mellitus, etc.

Ama refers to intermediate or by product of metabolism which have a tendency to block the microchannels of the body (srotas avarodha). So ama is an important factor for the manifestation of local or systemic diseases. So, ama plays a key role in pathogenesis of all diseases. [[Agni|Agni]] (digestive capacity) is not just pertaining to amashaya (stomach) or grahani only, but its present at every cellular level. So disturbance in [[Agni|agni]] can lead to formation of ama at cellular level also. This ama formation at cellular level can produce various disorders like rheumatoid arthritis etc. as mentioned above. Ama can be related with free radicals at cellular level.

Auto-immune diseases occur when immune system is attacked by anticipated response against antigen or toxins. These antigens or toxins trigger the inflammatory response. This concept of auto-immune disorders can be compared with the concept of ama. The antigen/toxins can be compared with ama, that produce improper metabolites/toxins within the body. This ama triggered inflammatory response in body results in number of the diseases. Ama at cellular level modulates the response of the body leading to develop incompatible autoimmune response that damages tissues. Crohn’s disease, psoriasis, rheumatoid arthritis, ankylosing spondylitis, are auto immune diseases caused by response against ama or antigen. The immune cells of the body do not attack the body cells suddenly, it happens because of lack of cellular communication as the cells being covered by ama or toxins. The ama is caused by weak digestive fire which affects the proper tissue production and oja (immunity) formation. So, we can consider the poor digestion and weak immunity is the root cause for auto-immune disorders. Therefore, by adopting ayurveda principles of treatment of ama, one can manage the auto-immune disorders.

<ol style='text-align:justify;'><li style="font-weight:bold">A clinical study on the role of ama in relation to Grahini roga and its management by kallingadi ghanavati and tryushnadi ghrita Discussion over role of ama in relation to Grahani disease: When the vitiated dosha get confined only to the organ grahani (duodenum), then it should be called ‘Grahani dosha’. But when the vitiated doshas travels throughout the rasadi dhatus (seven bodily tissues) i.e. throughout the body, then it should be called as ‘Grahani roga’ (functional impairment of [[Agni|agni]]). The grahani and [[Agni|agni]] (digestive process) are having co-existing nature/dependent on each other (adhara adheya sambandha). This view is confirmed by corroborative evidence from recent development in pathology. The mucosal damage in the form of villous atrophy and other microvillus changes in different enteropathies affect the enzymes present in the enterocyte brush borders. When the disease process progresses, further it affects the pancreatic secretion as it depends upon cholecystokinin and secretin secretion from the enterocyte. The immature epithelial cells are unable to secrete the required amount of cholecystokinin and secretin. In the pathogenesis (samprapti) of grahani disease, Acharya Charak elaborated a series of events as below.

Indulgence in causes that vitiate [[Agni|agni]] (digestive f) → [[Agni|agni]] dushti (vitiation og [[Agni|agni]]) → indigestion (apachana) → production of ama (non-metabolized, poorly formed product) → putreification (shukta paka)→ advanced condition of ama manifestating as a poisoning codition (anna visha or ama visha) → grahani dosha (functional impairement of grahini) → grahani dushti (vitiation of grahani)→ grahini roga (diseases manifestating as functional impairement of [[Agni|agni]]/digestive funtions). Ama is the root cause of almost all diseases produced in the body and the treatment of any disease can be based on stage of the disease associated with ama (saama) & stage of the disease not associated with ama (nirama avastha).

<li style="font-weight:bold">Association of stress inducing factors (manoabhitapakara bhava) and free radical over madhumeha Discussion over association of stress inducing factors (manoabhitapakara bhava) and free radicals with chronic metabolic diseases such as diabetes mellitus type 2 (madhumeha): This research explains about how adherence with stress (manobhitapakara bhava) lead to produce ama or free radical, and in turn produces chronic metabolic diseases.

<li style="font-weight:bold">A critical and comparative study of Ama and Free radical theory with special reference to Amavata Outcome of study: Free radical is an atom/molecule that contains one or more unpaired electron, which requires neutralisation by free radical scavengers. Thus it exists in an incomplete metabolic state which is also the state of ama described as incompletely digested (avipakvam). Free radicals cause damage to cell membrane and thus the cell is destroyed. This destruction may lead to putrification and foul smell generations which is similar to one of the property of ama described as unpleasant smell (durgandham). Though ama remains in the body as isolated or not mized (asamyuktam), but due to its properties like excessive sliminess (bahupicchilam) etc. it sticks to normal healthy body tissues very quickly, similar is the case with free radicals. To seek stability in their structure they quickly attack the healthy molecules of the body and thus setting a chain reaction. The cells throughout body are continously exposed to these damaging molecules, same has been described for ama as causing sluggishness of whole body (sadanam sarva gatranam). From above one can observe that properties of free radicals are similar to the properties of ama described in classics. Now the process of production of free radicals in body and production of ama would be considered. So it may be concluded that the causative factors (nidana) such as heavy to digest (guru ), unctuousness (snigdha) etc. qualities of diet (ahara) of amavata (rheumatism) as mentioned in the classics have a specific role to play in production of ama and also in the generation of free radicals. Also the line of treatment of ama advocated in the classics is effective in reducing the level of ama as well as free radicals. So it can be inferred that a positive correlation exists between ama and free radicals.<ref name="ref10">A critical and comparative study of Ama and Free radical theory with special reference to Amavata by Gaurav sharma, Department of Basic principles, IPGT& RA, Jamnagar, 2001.</ref></li>

<li style="font-weight:bold">A critical study of Trividhakuksiyavimana w.s.r. to amotpatti and its management Outcome of study: In this study, 2 groups are there, group I (treatment group) patients have been given chaturushna churna (powder) followed by wholesome diet (pathya) and light to digest food. Whereas, in group II (control group) patients received placebo treatment and wholesome diet (pathya) and light to digest food.. Dosha (ama dosha and tridosha (vata,pitta and kapha)) when adhere to amashaya (stomach), the desired response of the medicine may not be obtained which is observed in clinical study. Due to this the 21 days duration of therapy did not produce total cure response. So, we can say that if in disease, treatment regimens opposite to disease (vyadhi viparita ausadha) doesn’t produce good response, then it is to be inferred that here amashaya (stomach) is adhered with ama dosha. In this stage, as advised in Trividhakuksiyavimana adhyaya (2nd chapter of Charak Samhita Vimana Sthana), depleting therapy (apatarpna) should be administered.
