Shosha is the preparatory stage of gradual, generalized emaciation due to four distinct causative factors mentioned earlier which, if untreated or ignored, may lead to rajayakshma. One of the contributing factors of shosha is indicative of systemic depletion of dhatu occurring due to divergent causes. An important point to note here is that shosha is different from kshataksheena, a post-treatment stage of localized or generalized emaciation needing further intensive treatment.
Another commonly used term for shosha is kshaya (emaciation). However, it is imperative to clarify here that while shosha and kshaya are contextually similar and synonymous to yakshma , the specific meaning in Charak Samhita is different for all the three stages of the disease. Ayurveda is not very stringent when it comes to discerning cause-effect. Cause and effect are largely considered a continuum. While discussing the issue of cause-effect relationship between kshaya-shosha-yakshma, the concept of nidanarthakara roga has also to be kept in mind where one known disease or a morbid state can play as the nidana of another disease. That is why, kshaya is sometimes mentioned as cause of shosha too. The word kshaya in this particular context refers to pre-existing kshaya. Kshaya is of two distinct types - anuloma kshaya and pratiloma kshaya. Anulomakshaya is caused by the initial depletion of the ojas rasa situated in the heart, while pratiloma kshaya occurs due to an excessive indulgence in sexual activities leading to the depletion of shukradhatu which in turn leads to generalized vata vriddhi and vata induces shoshana of dhatus. Both these variants contribute to shoshana (qualitative and quantitative depletion of sharira dhatus or body tissues).
Shosha and kshaya can be considered as independent clinical entities warranting independent strategies for diagnosis and treatment. Either of these may prove to be a nidanarthakara factor for the occurrence of rajayakshma (i.e., if shosha or kshaya are left untreated, could lead to rajayakshma). Shosha is essentially a state of intractable emaciation, cachexia or consumption that could be equated to phthisis. It could be considered to be an intermediate state that may not necessarily exhibit any evidence of tubercular infection but because of persistent dhatukshaya(depletion of tissues) it could be logically associated with an immunocompromised state. Some patients may catch infections that may manifest into a febrile state with probable bacteriological invasion warranting appropriate treatment on the lines of rajayakshma. Because shosha and kshaya are intermediary states that are more of diagnostic significance than of significance from a core treatment perspective. Charak wrote the chapter on shosha in Nidana Sthana , while on rajayakshma in Chikitsa Sthana with the same motive.
It may appear that shosha and rajayakshma are synonymous because in this chapter there are brief descriptions of poorvarupa (preliminary signs) and ekadasha rupa (advanced stage) of yakshma. However, the manifestation of rajayakshma has been described in detail only in the Chikitsa Sthana.
While the focus of this chapter is to delineate the views of Charak, Sushruta in his text differs in his views on the relationship between shosha and yakshma. While Charak considers them as dependent entities as mentioned above, Susruta considers shosha distinctly different disease that could manifest itself in any of seven different variants caused by seven different causative factors (vyavaya or excessive sexual indulgence, shoka or sorrow, jara or rapid aging process, vyayama or excessive exercise, adhwagaman or excessive travelling, vrana or wound/trauma, and urakshata or chest injury.

There are four causes of shosha: overexertion, suppression of urges, wasting, and irregular consumption of improper food articles .
Each of these causes will be explained here in detail:
1. Overexertion as a cause

When a weak person fights against a strong one, or exercises with an excessively large (or weighty) bow (weapon), or speaks too much, or physically carries a lot of weight, or swims across a long distance in water, or is habitually subjected to forceful massage including kneading with feet, or sprints over a long distance, or is assaulted, or practices various complicated or excessive physical exercises, his lungs are “traumatized” due to excessive exertion. This aggravates vayu in the lung region, taking along kapha residing in the lungs while also affecting pitta, causing the vitiated doshas to spread upwards, downwards and obliquely. A portion of this afflicted dosha system that gets into body joints causes yawning, body ache, and fever. That which gets into the amashaya causes diseases of lungs and anorexia. That which gets into the throat causes irritation of the throat and hoarseness of voice. That which gets into the channels carrying vital breath (bronchial channels) causes dyspnea and coryza. And that which gets into the head produces distress in the head. Thus, due to wound in lungs, irregular movement of vayu causes a variety of diseases depending upon the organs it gets into. The lungs get damaged further, triggering conditions such as hemoptysis and consequently weakening the patient. This verse, therefore, advises the reader to engage in laborious activities appropriate to his strength and not overexert himself. [4-5]
2. Suppression of natural urges as a cause

When a person suppresses the urge to pass flatulence, urination, and bowel movement due to various reasons such as attending a royalty, being in a formal setting (in the company of sages, teachers, nobles, etc), being in the midst of women, society of gambling, or while traveling on uneven vehicle, or due to fear, environment, bashfulness or disgust, vayu gets vitiated due to suppression of urges. This vitiated vayu aggravates pitta and/or kapha, spreading upwards, downwards or obliquely depending upon the combination of afflicted doshas. As said earlier, when a portion gets into specific body parts, it causes pain, diarrhea or drying up of feces, excessive pain in sides of the chest, pain in the shoulders, irritation in throat and lungs, headache, cough, dyspnea, fever, hoarseness of voice and coryza. Thereafter, having been afflicted with these wasting complications, the patient gradually gets afflicted with shosha. Hence the wise should carefully observe the ways that promote and protect the body.
Here is the verse: Setting all other things aside, one should protect the body, because in its absence there will be complete absence of all the bodily entities. [6-7]
3. Wasting as cause

Now explained is wasting as the cause of shosha. When a person is suffering excessively from anxiety and grief, or from emotions like envy, fear, anger, etc., and if the person is also afflicted with a wasting disorder and/or using rough food and drinks, or if a congenitally weak person is subjected to fasting or malnutrition, his ojas gets diminished leading to shosha. Due to want of proper management and care, he could get afflicted with the disease having symptoms to be described later. 
4.Excessive sexual indulgence as a cause*

When a person indulges in excessive sexual intercourse habitually, his semen gets diminished. In spite of diminished semen, if he obsesses about sex mentally as well as physically and continues to engage in sexual acts with excessively determined passion, his semen is not discharged because of its already diminished state causing vayu to enter his blood vessels and blood getting discharged from the seminal passage. Now, due to loss of semen and hemorrhage, his joints loosen, the skin loses its suppleness and becomes rough or scaly, body weakens further and vayu gets vitiated. The vitiated vayuspreads in the body deficient of semen and blood, aggravating kapha and pitta and drying up the muscles and blood. Further, the vitiated vayu expels kapha and pitta, causing pain in the sides of the chest and shoulders, irritation of throat, aggravating kapha of the head and replacing it with the vitiated kapha expelled from their natural locations, causing pain in joints, body ache, anorexia and indigestion. Due to frequent cough the lungs get damaged and hemoptysis ensues, debilitating the patient further and afflicting him with wasting complications. If untreated, the patient gradually is afflicted with phthisis.
Here is the verse: Semen is the final essence of one’s food hence it should be protected because its depletion leads to many diseases or even death. [8-9]
- * This is not mentioned as a main cause of shosha in verse 3, but is a derivation of verses 8-9.
5. Irregular meals/Improper meals as a cause

This verse talks of irregular diet as a cause of shosha. When a person takes food – drinkable, eatable, chewable and lickable – irregularly in terms of nature, preparation, combination, quantity, place, time, and various dietary rules (do’s and don’ts) appropriate for his constitution, his doshas get imbalanced. These imbalanced doshas spread in the body, obstructing the openings of various channels and the flow of dhatus. In such cases, the body survives on the support of malas. Hence mala should be protected, particularly in case where the patient has already been afflicted with phthisis and in cases where the individual is emaciated or very weak. The vitiated vata causes pain, body ache, irritation of throat, chest pain, pain in shoulders, hoarseness of voice and coryza. Vitiated pitta causes fever, diarrhea, internal heat and vitiated kapha causes coryza, heaviness of head, anorexia and cough. Due to frequent bouts of cough, lungs get damaged and hemoptysis ensues, consequently debilitating the patient further and causing shosha. Having been afflicted with these wasting complications, the patient gradually becomes very weak and gaunt.
The final verse advises thus: Observing many troublesome diseases caused by irregular dieting, the wise should eat wholesome, measured and timely food with self-restraint. [10-11]

Regular use of the four etiological factors of shosha vitiates the doshas. These vitiated doshas dry up the body while afflicting it with various complications. Physicians call it rajayakshma because it is most troublesome among all the diseases (rajayakshma would literally translate to the “king of yakshmas”) or because in vedic mythologies, it afflicted Lord Moon, the king of stars.

Shosha’s prodromal symptoms include coryza, frequent sneezing, excessive secretion of mucus, a sweet aftertaste in the mouth, aversion to food, exhaustion during meal time, finding fault with utensils, water, cereals, pulses flour preparations, spicy preparation and caterers who are free from fault or have a little fault. A person afflicted with shosha will experience nausea after meals, intermittent vomiting during meals, swellings in the face and feet, tendency of frequently looking at the hands, excessive whitishness in the eyes, curiosity about measurement of arms, longing for women, disgust, loathsome view of his body, frequent dreams of waterless/arid places as well as places such as deserted villages, cities, districts and regions, of forests dried, burnt and destroyed. Such a person would often be using vehicles drawn by, or coming in contact with, or riding animals like chameleon, peacock, monkey, parrot, serpent, crow, owl, dog, camel, ass and boar, and riding over heaps of hair, bones, ash, chaff and charcoal.

One having all the above symptoms of shosha should be considered curable in case his strength, muscles and blood are not wasted, he is strong and the fatal signs have not appeared. The strong and well-nourished, because of tolerance to intensity of disease and drugs, should be assumed to have fewer symptoms even if they have many, and treated accordingly.

On the contrary, the patient who is weak and has excessively diminished strength, muscles and blood should be taken as having numerous symptoms including the fatal ones, even if he has few symptoms and no fatal signs because of his intolerance to the intensity of disease and drugs. Hence he should be discarded (for treatment) because the fatal signs appear in a moment and without any apparent cause.

Now the (summing up) verse –
He is capable of treating the king who knows, in essence, the etiology, symptoms and prodroma of shosha.
Thus, ends the sixth chapter on diagnosis of shosha in Nidana Sthana in the treatise composed by Agnivesha and redacted by Charak. [16-17]
Tattva Vimarsha / Fundamental Principles
- Wasting or emaciating conditions like shosha occur because of four factors: Sahasa (overexertion), Sandhaarana (suppression of natural urges), Kshaya (emaciation), and Vishamasana (Dietary error).
- The common effect of the four factors is dhatukshaya (loss of body tissue), especially rasa which is responsible for maintaining vyadhikshamatya (Immunity).
- Sahajabala (Innate immunity) is fundamental to prognosis of the disease. If sahajabala is intact, the outcome of treatment is favorable, even if the symptoms are full blown.
- Etiological factors, dosha vitiation and clinical features help in understanding the pathophysiology of the disease.
Vidhi Vimarsha / Applied Inferences
The point of significance in this chapter is the identification of the intermediary clinical state called shosha which is the precursor to rajayakshma, a pathological state warranting early diagnosis and treatment as a promotive health care strategy. Sushruta acknowledges the specific role of microbial infection through direct physical contacts as the real cause, while Charak emphasizes upon the role of pre-existing progressive weakness and emaciation accompanied with lowered vyadhikshamatva (poor immune strength) as some of the key causative factors responsible for the entire spectrum of the disease complex that includes shosha, kshaya, and rajayakshma. This fundamental idea for which Charak devotes one full chapter in Nidana Sthana is an original contribution of Charak, drawing specific attention to the fact that the host factor and host resistance against disease is more important than the causative microbial organism in case of contagious diseases like tuberculosis. It also endorses the Ayurvedic stand that the solution lies in enhancing or strengthening the immunity of the host and not merely in tackling the microorganisms afflicting the person. Use of antibiotics, as is prevalent in western medicine, is now dwindling because of their adverse side effects and rapidly emerging problems associated with drug resistance. In fact, there is now a growing consensus that an idea of an antibiotic war in medicine is anti-life and anti-health.
The recent advances in biomedical sciences unfolding the shape and role of genome, epigenome and microbiome in human health have partly proven the generic fact that our genes, our environment and “friendly” microbes are our collective friends and are an integral part of our being. They are protective tool for the immune-enhancing through positive life style, healthy dietetics and regulated use of rasayana remedies. Rasayanas are described in Ayurveda for promotive and preventive health care as well as for promotion of longevity.
Recent researches on rasayana drugs such as amalaki and ashwagandha have appeared in certain high impact journals. Lakhotia et al, in their 2012 study on drosophilia model, have recorded marked DNA repairing effects besides better maturation rate and healthier and longer life span in fruit flies treated with amalaki rasayana. Similarly, Kuboyama et al (2005) have reported that withanolide-A, isolated from the ashwagandha rasayana, has significant regenerative effect on neurons. Singh et al (2008) reported neuro-nutrient impact of Ayurvedic rasayana therapy while Jayprakash et al (2013) reported the neuroprotective role of ashwagandha in experimentally induced Parkinsonism. In view of the conceptual strength and the recent scientific studies now it could be suggested that rasayanas like amalaki, chyavanprasha and ashwagandha should be used in the management of shosha, kshaya and yakshma with great advantage, besides administration of other therapeutics described in Ayurvedic texts.
As mentioned earlier, Ayurvedic texts propound the doctrine of an immunocompromised state as the precursor of chronic wasting diseases like shosha, kshaya and yakshma. Sushruta, while describing the samkramaka (contagious diseases) specially, observes that jwara, shosha, rajayakshma, abhisyanda or conjunctivitis, and kushtha (or dermatoses such as leprosy) spread from person to person by contact. The spread of such diseases may be prevented by avoiding personal contacts and by promoting vyadhiksamatva or immunity with the help of leading a healthy lifestyle, following good nutrition and through administration of rasayana therapy.
Ojas (vital essence of the body)
The Ayurvedic classics describe a unique hitherto-less-known concept of ojas (vital essence of the body) that is responsible for biological strength (including immunity). Ojas is the final product of tissue nourishment and is quintessential to all the seven dhatus namely rasa, rakta, mamsa, meda, asthi, majja, and shukra. Sushruta describes ojas as the param teja of the saptadhatus and as the bala or biological strength of an individual. Ojas is of two kinds, namely, para ojas and apara ojas. Para ojas is subtle and present in very minute quantities in the heart while apara ojas is gross and as much as half an anjali (handful) in quantity spread all over the body. Para ojas is vital to life and any damage or vitiation of it may lead to instant death. Apara ojas is responsible for gross immune strength.
The oja-bala (ojas strength) derived from ojas has been categorized to be of three kinds: sahaja bala or primary natural immunity, kalaja bala or acquired immunity through environmental factors such as climate etc., and yuktikrit bala or artificially-induced acquired immunity. The classics prompt to utilize these three resources to enhance the bala/immunity in order to prevent all ailments especially chronic wasting diseases and contagious diseases, such as shosha, kshaya and yakshma.
The texts describe three categories of bala-dosha or disorders of bala which are comparable to three categories of immune disorders such as :
- Oja-vyapat (immune-aberrations and allergies),
- Oja-visransa (dislodged immunity and autoimmune disorders), and
- Oja-kshaya (immunodeficiency).
There are specific methods and approaches to tackle the three categories of immune disorders.
It cannot be overemphasized that while looking at the above mentioned ancient classical descriptions on ojabala and bala-dosha it seems immunology was already highly advanced in the Samhita period of Ayurveda and the knowledge in this field was almost comparable with the latest basic knowledge of immunology as known today.
Ancient Ayurvedic leads in Microbiology
It will be pertinent to review the concept of microbiology and parasitology in Ayurvedic classics in the context of immunity and body resistance. Ojas, bala and vyadhikshamatva need to be adequate within the body for it to possess immunity. Though the role of microbes in pathology was not known in modern medicine 200 years ago, Ayurveda had a good knowledge of their role, albeit of a primitive nature. Ayurveda describes two kinds of organisms, namely prakrita (non-pathogenic) and vaikrita (pathogenic). Also described are two categories of pathogens/parasites, namely, external and internal. The internal organisms are mainly of three categories in terms of their natural environments: those that thrive on mucus (shleshma), those thriving in fecal matter, and those thriving in blood. Some of these, particularly the ones thriving in fecal matter seem to be intestinal parasites while others simulate microbes. The texts repeatedly advocate protecting surgical wounds from these organisms. There is also a clear description of vector borne diseases and that diseases such as leprosy, tuberculosis, conjunctivitis and fever as contagious diseases spread by contact with other patients or vectors.
It is interesting to note that these ancient texts recognized the existence of “friendly” non-pathogenic organisms and their functions - something that is only now being considered the greatest discovery in microbiology .It is claimed by modern scientists that our living body is made up of 10 trillion somatic cells and is home to some 100 trillion friendly microbes. This “empire” of microbes is called Microbiome. Understanding the relationship between the microbiome and the human being, the animal and the environment - is as important as unravelling human genome. The microbiome is like a well structured organ with unique functions and hence needs to be protected in the same way as we protect our other vital organs like liver, heart or kidney. This recognition of the existence of these friendly prakrita (non-pathogenic organisms) by Ayurveda thousands of years ago is of great historical significance.
