Diseases caused by aama
आमसंज्ञां स लभते बहुव्याधिसमा-श्रयः (Vachaspatyam762)
The concept of aama or aama as the entity is the cause of several diseases. Aamavata, alasaka, visuchika, aamatisara to mention a few.
Acharya Charaka explained specifically alasaka and visuchika as prime diseases caused by aama.
Alasaka
The non-expulsion of undigested food or aama from the body is alasaka. There is obstruction cause because of kapha dosha along with the involvement of weak agni. (cha.vim2.12)
Visuchika
The expulsion of undigested food or aama dosha through upper and lower passages meaning, vomiting and diarrhoea is visuchika. (cha.vim.2.11)
Aamavata
Excessive unctuous food when taken right after the exercise, in the presence of weak agni, this food doesn’t get digested appropriately and aama is formed. This aama gets circulated with the help of vata dosha in the whole body and finally accumulates in the sandhi sthana (joints) causing pain, fever, heaviness of the body, and other symptoms. This is very commonly co-related with Rheumatoid arthritis. (madh.nida.25.1-6)
Aamaatisara
When excessive heavy, unctuous, dry food, incompatible food is taken on a chronic basis and untimely, the food does not get digested appropriately and aama is formed, this leads to amatisara. Aamatisara is mildly co-related with dysentery. Where there is a pain in the abdomen, increased motion frequency along with other symptoms. (madh.nida.3.1-11)
Management of Ama disorders
(cha.vim2.13)
In visuchika, langhana(therapeutic fasting) is advised followed by a strict dietary regimen. Application of suppositories and Further,if still not managed Virechana or Purgation is done.
In certain cases of ama disorders, ahara (food) is not recommended at all, because the derangement of agni(digestive fire) is incapable of digestion. And food intake can derail the agni(digestive fire) further leading to the severity of the disorder.
Also, Aptarpana means fasting or undernutrition is adopted as well.
Nidana privarjan chikitsa method is adopted as well, which means the exclusion of the factors which caused the disease in the first place.
When the aama is skilfully digested basti chikitsa is administered systemically.
Administration of Pachana and Deepana dravya.
Pachana –
Pachana means digestion. It is karma or the action of a certain drug on the body. The dravya or drug that acts by digesting the undigested food or aama in the body is the pachana dravyas. These dravya digest what is undigested without stimulation of the agni (digestive fire). one such example of Pachana dravya is Haritaki(Terminalia chebula). (sha.purv.4.1)
Deepana
Deepana means stimulating, here it means stimulation of digestive fire meaning agni. Thus, the karma of the dravya which initiates the kindling of agni(digestive fire) is termed deepana dravyas. One such example of deepana dravya is shatapushpa(Anethum sowa). Hot water, and cow’s milk are examples of depana karma dravya which are used routinely (Sush.Sutra 45.39 and 51) . Snana (bathing) is also one example of deepana karma(Asht.hrid sutr 2.16).
Pachan, snehan (anointing) and swedana(therapeutic steam) methods of dosha expulsion should be adopted according to the rutu(season) and bala(strength) of the patient, pathway of expulsion(vamana or emesis, virechana or purgation). (Asht,hrid.sut.13.29)
Saamadosha (ash.hrid.sut.13.27)
When doshas(vata, pitta, kapha) and dhatus, like rasa, rakta etc are contaminated because of aama formation then these doshas are termed as sa-aama doshas. And when a certain individual is affected with any disease when doshas are in sa-ama condition the diseases are also in sa-ama stage. This is important from a Vaidya’s or physician's point of view while planning the treatment.
Sama pitta dosha
Asht.sutr.13
Sa-ama dosha lakshana| Symptoms of sa-ama dosha in body (ash.hrid.sut.13.23-24)
1. Obstruction of strotas(channels/passage)
2. Laziness
3. Heaviness in the body
4. Loss of strength
5. Exhaustion
6. Constipation
7. Indigestion
Management of saama dosha
When sa-ama doshas arespread across the body, when they are unified with dhatus(tissues), shodhana chikitsa method or expulsion of doshas from the body should not be adopted. Shamana chikitsa(pacification of doshas through oral medication) must be adopted initially. (ash.hrid.sut.13.28)
On the contrary, when the doshas are highly vitiated, they get expelled out in the form of vomit or diarrhoea, and these doshas should not be stopped. If done so are capable of producing diseases. (ash.hrid.sut.13.31).
