2. INTRODUCTION
Ayurveda is known as science of living beings. It
concerns over the maintenance of health of healthy living
beings and restoration of health of the diseased ones.
Thus, the first aim of Ayurveda is maintenance of health
which is comprised of Dina Charya, Ritu Charya, Sadvritta
etc.
In this seminar, we are going to discuss about the
measures of maintenance of health throughout the year with
the help of Ritucharya to obtain seasonal homologation.

3. Acharya Charaka has described Ritucharya in Charak
Sutrasthan Chapter 6 whereas Sushruta described it in
Sushrut Uttartantra Chapter 64 ,While Acharya Vagbhata
described in Ashtang Hridaya Sutrasthan Chapter 3.
In this seminar, we will discuss the Ritucharya as
described by Acharya Charaka in Tasyashitiya Addhyaya of
Sutrasthana.

6. According to M. Monier Williams:-
Ritu :–
• Any settled point of time
• Fixed time
• Time appointed for any action
• Right or fit time
• An epoch, period, season
• Menstrual discharge in women
• Symbolical expression of number six

7. SANVATSARA VIBHAGA
इह खलु संवत्सरं षडङ्गमृतुववभागेन ववद्यात्|
तत्रादित्यस्योिगयनमािानंaच त्रीनृतूञ्छिशिरािीन्ग्रीष्मान्तान्
व्यवस्येत्, वषाािीन्पुनहेमन्तान्ता िक्षिणायनं ववसगं च ||
Ch.Su.6/4
Now the year, it should be known , consists of six parts
when divided according to the seasons, from among these,
the three seasons from the dewy season to the summer
represent the sun’s northern course and his period of
absorption; while the three seasons from the rains to the
winter represent the sun’s southern course and his period of
liberation.

8. NATURE OF THE AYANAS
ववसगे पुनवाायवो नाततरूिााः प्रवाञ्न्त, इतरे पुनरािाने;
सोमश्चाव्याहतबलाः शिशिराशभभााशभरापूरयछजगिाप्ययाययतत िश्वत्,
अतो ववसगााः सौम्याः | आिानं पुनराग्नेयं; तावेतावर्ा वायू सोमश्च
र्ालस्वभावमागापररगृहीतााः र्ालतुारसिोषिेहबलतनवृाविप्रत्ययभूतााः
समुपदिश्यन्ते || Ch. Su. 6/5
During the period of liberation, the prevailing winds are not
marked by excessive dryness; it is otherwise with the period
of absorption. During the former the moon with unabated
vigour aggrandizes the earth by surcharging it with her cool
radiations and nourishes it constantly; therefore the period
of liberation is characterized by the predominance of the
water element. On the other hand, the period of absorption is
characterized by the predominance of the fire element.

9. In this manner, the sun, the wind and the moon, governed
by time as well as their own special natures and orbits, are
spoken of as the causative factors of the manifestations of
the periods, seasons, tastes, humors and bodily strength.

रसांञ्स्तक्तर्षायर्टुर्ांश्चाशभवर्ायन्तो नृणां िौबाल्यमावहञ्न्त ||
Ch. Su. 6/6
During the first period, the sun with his hot rays absorbs
the moisture from the earth, and the piercing dry winds
giving rise to progressive dryness and promoting the
formation of the three tastes – bitter, astringent and pungent
respectively – lead to gradual waning of strength in men.

12. VISARGA KALA
वषाािरद्र्ेमन्तेषु तु िक्षिणाशभमुखेऽर्े

Ch. Su. 6/7
From the season of the rains to the autumn and the winter,
however, the sun who has his face to the south, being shorn
of his glory by the cumulative influence of period, orbit,
clouds, winds and rains, the moon, remaining undiminished
in power, and the summer heat having been quenched by the
rains, it is the non – dry group of tastes – sour, salt and
sweet- that increases in the given order. During this period
too the strength of the men waxes.

13. भवतत चात्र-
आिावन्ते च िौबाल्यं ववसगाािानयोनृाणाम्मध्ये मध्यबलं, त्वन्ते

In the beginning and the end of the sun’s period of
liberation and absorption respectively, the bodily vigour of
men is at its lowest; in the middle of this periods, it is the
moderate; while, it should be known, that at the end of the
former and the beginning of the latter period, the bodily
vigour is at its highest.

17. HEMANT CHARYA
Doshica conditions in Hemanta:-
िीते िीतातनलस्पिासंरुद्र्ो बशलनां बली |पक्ता भवतत हेमन्ते
मात्रारव्यगुरुिमाः || स यिा नेन्र्नं युक्तं लभते िेहजं तिा | रसं
दहनस्त्य तो वायुाः िीताः िीते प्रर्ु प्ययतत || Ch. Su. 6/9 - 10
In the cold season or winter, the gastric fire in strong men,
hemmed in by the cold air all around, becomes greatly
enhanced and capable of digesting heavy food intake, both
as regards of measure and quantity of the articles.
If such gastric fire does not get sufficient amount of fuel
i.e. the food, then it consumes the body - fluids and thus the
Vata possessed of cold quality, is provoked in the cold
season.

18. Aahara in Hemanta:-
तस्मािुषारसमये ञ्स्नग्र्ाम्ललवणान्रसान्| औिर्ानूपमांसानां
मेद्यानामुपयोजयेत्|| बबलेियानां मांसातन प्रसहानां भृतातन च|
भियेन्मदिरां िीर्ुं मर्ु चानुवपबेन्नराः|| Ch. Su. 6/11 – 13
Hence in the season of snows, i.e. the winter, one should
take unctuous, acid and salt juices of the flesh of fatty
animals of the aquatic and wet – land varieties. One should
take the spit – roasted flesh of the burrowing and “Prasaha”
i.e. the tearer group of animals, followed by a potion of
Madira and Seedhu wines and honey.

19. गोरसातनिुववर्ृ तीवासां तैलं नवौिनम्|
हेमन्तेऽभ्यस्यतस्तोयमुष्णं चायुना हीयते||
Ch. Su. 6/13
One who uses habitually, in winter, milk products,
preparations of sugar cane juice, animal fat, oil, new rice,
and warm water, protects his life – span from diminution.

20. Vihara in Hemanta:-
अभ्यङ्गोत्सािनं मूञ्ध्ना तैलं जेन्तार्मातपम्| भजेद्भूशमगृहं
चोष्णमुष्णं गभागृहं तथा || िीतेषु संवृतं सेव्यं यानं ियनमासनम ्|
प्रावाराञ्जनर्ौषेयप्रवेणीर्ु थर्ास्तृतम्|| गुरूष्णवासा दिग्र्ाङ्गो
गुरुणाऽगुरुणा सिा |
One should resort to inunction, oil – massage, oil –
shampoo, hot – house sudation, sun – baths, warm cellers
and warm inner apartments in winter. In cold season, one
should have vehicles, beds and seats well covered and
spread with thick quilts and deer skin or tiger skin, silk
sheet, gunny – cloth sheets or with variegated blankets.
When winter begins, one should always wear warm and
thick clothing and should have one’s body anointed with
thick paste of eagle – wood.

21. Apathya in Hemanta:-
वजायेिन्नपानातन वातलातन लघूतन च | प्रवातं प्रशमताहारमुिमन्थं
दहमागमे ||
On the advent of the cold season, one should give up
eats and drinks that are light and provocative of Vata, and
should avoid draughts, measured diet and diluted Mantha.

22. Acharya Charaka has described Hemanta Ritucharya first
while explaining Ritucharya, and He suggested to impliment
the same regimen in Shishira Ritu also.
As the weather conditions in Shishira are getting more
cold and dry, the regimen is to be followed even more
stringely as follows.

23. SHISHIR CHARYA
हेमन्तशिशिरौ तुल्यौ शिशिरेऽल्पं वविेषणम ्| रौक्ष्यमािानजं िीतं
मेघमारुतवषाजम ्|| तस्माद्र्ैमञ्न्तर्ाः सवााः शिशिरे ववधर्ररष्यते|
तनवातमुष्णं त्वधर्र्ं शिशिरे गृहमाश्रयेत ्||
Ch. Su. 6/19 – 20
Winter and the dewy season are similar in nature; yet
there is a slight distinguishing characteristic in the dewy
season, namely, the dryness born of the sun’s absorbing
period and the cold born of clouds, wind and rain.
Therefore, the whole regimen prescribed for winter is to be
observed in the dewy season as well. In fact, the rule as to
residence in draught less and warm apartments is to be
observed even more stringently in the dewy season. One
should avoid eats and drinks that are pungent, bitter,
astringent, provocative of Vata, light and cold.

24. VASANTCHARYA
Doshica conditions in Vasanta:-
वसन्ते तनधचताः श्लेष्मा दिनर्ृ द्भाशभरीररताः | र्ायाञ्ग्नं बार्ते
रोगांस्तताः प्रर्ु रुते बहून्|| तस्माद्वसन्ते र्मााणण वमनािीतन र्ारयेत्|
गुवाम्लञ्स्नग्र्मर्ुरं दिवास्वप्यनं च वजायेत्|| Ch. Su. 6/22 – 26
The accumulated Kapha, getting liquefied by the hot rays
of the sun in the spring, affects the body – heat and thus
gives rise to many diseases. Therefore, in the spring,
purificatory procedures such as vomiting and others should
avoid heavy, acid, unctuous and sweet articles as also day –
sleep.

25. Aahar and Vihar:-
व्यायामोद्वर्तनं धूमं कवलग्रहमञ्जनम् | सुखाम्बुना शौचवववधं शीलयेर्् कसुमागमे ||
चन्दनागुरुवदग्धाङ्गो यवगोधूमभोजनः | शारभं शाशमैणेयं मांसं लावकविञ्जलम् || भक्षयेवन्नगतदं
सीधुं विबेन्माध्वीकमेव वा | वसन्र्ेऽनुभवेर्् स्त्रीणां काननानां च यौवनम् || Ch. Su. 6/24
- 26
On the advent of spring, one should resort to physical
exercise, dry massage, smoke, gargles, Collyrium and
frequent ablutions with genially warm water.
On should anoint one’s body with sandal – wood or eagle
– wood paste, eat a meal prepared of barley or wheat, flesh
of Wapity, rabbit, Indian antelope, grey quell and gray
partridge.
One should drink wholesome Seedhu or honey and enjoy
the youthful loveliness of women and gardens.

26. GRISHMACHARYA
Doshica Conditions in Grishma:-
मयूखैजागताः स्नेहं ग्रीष्मे पेपीयते रववाः| स्वािु िीतं रवं
ञ्स्नग्र्मन्नपानं तिा दहतम्|| Ch. Su. 6/27
In summer, the sun drinks up the unctuous element of the
earth. During this season, therefore, foods and drinks that
are sweet, cool, liquid and unctuous are conductive to
health.

27. AAHAR AND VIHAR:-
िीतं सिर्ा रं मन्थं जाङ्गलान्मृगपक्षिणाः | घृतं पयाःसिाल्यन्नं
भजन ्ग्रीष्मे न सीितत || मद्यमल्पं न वा पेयमथवा सुबहूिर्म्|
लवणाम्लर्टूष्णातन व्यायामं च वववजायेत ्||
Ch. Su. 6/28-29
By recourse to a diet of cold mantha sweetened with
sugar, the flesh of animals and birds of the jangala group,
ghee, milk and Sali rice, one escapes the enervating effects
of the season.
Little or no wine should be drunk or it should be drunk
diluted liberally with water. One should, further, give up
foods that are salt, sour, pungent and hot, as also exercise.

28. दिवा िीतगृहे तनरां तनशि चन्रांिुिीतले |

र्ु सुमातन च | ग्रीष्मर्ाले तनषेवेत मैथुनाद्ववरतो नराः ||
Ch. Su. 6/30-32
Smearing oneself with sandal-paste, one should sleep by
day in the cool apartment of the house, and by night, on the
terrace, cooled by the rays of the moon and open to the
breezes.
Adorned with pearls and gems, one should seek the couch,
being ministered to by waving of fans and the caresses of
tender hands which are cool with sandal-water.
In the summer season, one should abstain from sexual
intercourse, and seek the coolness of woods, waters and
flowers.

29. VARSHA CHARYA
Doshica conditions in Varsha Ritu:-
आिानिुबाले िेहे पक्ता भवतत िुबालाः |
स वषाा स्वतनलािीनां िूषणैबााध्यते पुनाः || Ch. Su. 6/33
In the body that has been impoverished by the effects
of the sun during his period of absorption, the digestive
power too grows weak. Then on the advent of the rainy
season, the digestive power readily succumbs to the
morbid effects of Vata and other humors.

30. भूबाष्पान्मेघतनस्यन्िात ्पार्ािम्लाज्जलस्य च |
वषाास्वञ्ग्नबले िीणे र्ु प्ययञ्न्त पवनाियाः || तस्मात ्सार्ारणाः
सवो ववधर्वाषाासु िस्यते| Ch. Su. 6/34-35
The humors in their turn, finding the strength of the
gastric fire weakened, get provoked aided by the effects of
moist - hot exhalations from the earth, the precipitation of
rains and the tendency to acidity in water which occur in the
rainy season.
Accordingly, the general rule that is laid down for the
rainy season is moderation.

31. Aahar and Pathya
उिमन्थं दिवास्वप्यनमवश्यायं निीजलम्|| व्यायाममातपं चैव व्यवायं
चात्र वजायेत्| पानभोजनसंस्र्ारान्प्रायाः िौराञ्न्वतान्भजेत्||
व्यक्ताम्ललवणस्नेहं वातवषाार्ु लेऽहतन | वविेषिीते भोक्तव्यं
वषाास्वतनलिान्तये || Ch. Su. 6/35-37
One should in particular avoid watery mantha, day –
sleep, frosts, river – water, exercise, sun and sexual
intercourse during this season.
One should, as a rule, take foods and drinks that are well
seasoned, in combination with honey.
On the very cold days marked by stormy winds and rain,
one should, even in the rainy season, take unctous articles
with pronounced acid and salt tastes for the sake of
alleviating Vata.

32. अञ्ग्नसंरिणवता यवगोर्ूमिालयाः | पुराणा जाङ्गलैमांसैभोज्या

वा | माहेन्रं तप्यतिीतं वा र्ौपं सारसमेव वा || Ch. Su. 6/38-39
One, taking care to preserve his gastric fire, should take
old barley, wheat and Sali rice together with the flesh and
well seasoned soups of the jangala group of animals.
One should drink, mixed with honey, a small measure of
decocted honey – wine or rain water, well – water or lake –
water that has been boiled and cooled.

33. Vihara:-
प्रघषोद्वतानस्नानगन्र्माल्यपरो भवेत ्| लघुिुद्र्ाम्बराः स्थानं
भजेिक्लेदि वावषार्म्|| Ch. Su. 6/40
In the rains one should have recourse to friction –
massage, dry massage, bathing, wearing of perfumes and
garlands, light and clean habiliments, residing in the rain –
house (house designed for residing in the rains) i.e. free
from damp.

34. SHARAD CHARYA
Doshica conditions in Sharad Ritu

When the body, which has become habituated to the cold
of rains, is suddenly heated by the rays of the sun in the
autumn, the accumulated pitta in the body is generally
provoked.

35. Aahar,Vihar and Pathya
तत्रान्नपानं मर्ुरं लघु िीतं सततक्तर्म ्| वपिप्रिमनं सेव्यं

In this season one should partake of eats and drinks that
sweet, light, cooling, slightly bitter, and curative of pitta, in
due dose and when really hungry.
Also, one should take the flesh of grey quail, grey
partridge, black buck, wild sheep, wapiti and hare, Sali rice,
barley and wheat.
When the rain clouds have disappeared, one should resort
to a potion of ghee medicated with bitter articles, to
purgation and depletion of blood,

One should avoid exposure to the sun, also should avoid
in this animal fats, oils, exposure to frosts, flesh of aquatic
and wet – land animals, alkalis, curds, day – sleep and
easterly winds.

37. HANSODAKA

Ch.Su.6/46-48
The water of the autumn which is well heated by the rays
of the sun during the day and well cooled by the rays of the
moon by night, perfected and freed from impurities by the
course of time and detoxicated by the radiations of the star
Agastya ( Canopus ) and which is clear and pure, is called
Hansodaka ( Pure water which is beloved by swans ).
This autumnal water is crystal clear and clean, and the use
of this water for bathing, drinking or immersion is as
beneficial to the body as ambrosia.

38. िारिातन च माल्यातन वासांशस ववमलातन च |
िरत्र्ाले प्रिस्यन्ते प्रिोषे चेन्िुरश्मयाः ||
Ch. Su. 6/48
Garlands of autumnal flowers, spotless garments and
exposure to moonlight in the early part of the night are
recommended in the autumnal season.

39. IMPORTANCE OF RITUCHARYA
तस्याशिताद्यािाहाराद्बलं वणाश्च वर्ाते | यस्यतुासात्म्यं ववदितं
चेष्टाहारव्यपाश्रयम ्|| Ch. Su. 6/3
According to Ayurveda, an enhancement of strength and
lusture includes happiness etc. caused by the maintenance of
tissue elements.
Acharya Charaka says that the seasonal dietary and
regimen practiced by a man who knows the seasonal
homologation with regard to behavior and diet, promote his
vigor and complexion.

40. RITUSANDHI :-
In order to keep the homeostasis, one has to take care of
his dietetics and other regimen of life during the change of
seasons, as one accustomed to one particular routines of a
season, if happens to face the change of another, he is bound
to follow certain principles advocated in Ayurveda under the
heading of Ritusandhicharya.
It is the period which precipitates at the junction of two
seasons when a person gives up the established dietetics and
regimen of one season and accepts the new of another
season.

41. The Ritusandhi though principally has been accepted by
Acharya Charaka but it is only explained in Ashtang
Sangraha.
It has been said that the last seven days of the previous
and the first seven days of the ensuing season ( fourteen
days ) is called Ritusandhi.One should give up and start the
regimen of the previous and coming season simultaneously
to avoid the unhomologous diseases.

42. YAMADANSHTRA :-
This term has been used by Acharya Sharangdhara
representing a junction period of Kartika (Oct. - Nov.) and
Margashirsha (Nov. – Dec.).
This period has been designated to be influenced by
Yamaraja – the one who takes away the life of the
individual.The text reveals that the last eight nights of
Kartika and first eight nights of Margashirsha is called
Yamadanshtra and one who takes meals in less quantity,
remains happy in these period.
The period is of great importance due to forming a
junction of two Ayanas (Visarga and Aadana) of the year.

43. MODERN PERSPECTIVE
The weather has found to have a profound effect on
human health and well being. Medical disorders such as
bronchitis, peptic ulcer, adrenal ulcer, glaucoma, goiter,
eczema and herpes zoster are related to seasonal variations
in temperature.
Humidity has also a considerable influence on morbidity
in the winter because cold, dry air leads to excessive
dehydration of nasal passages and the upper respiratory tract
and increased chance of viral and microbial infection.
Even birth rates and sperm counts appear to be affected
by meteorological phenomena.

44. Floris AD et.al(2009) examined the effect of birth season
on fetal development and longevity and found that
significantly increased birth weight, gestational age and
longevity in individuals born during the autumn and winter
seasons of the year.
These individuals also established statistically significant
lower prevalence rates for fetal growth restriction and
premature birth. Also they observed increased temperature at
the time of birth linked with adverse effects on fetal
development and longevity.
Heart failure and cerebrovascular accidents have been
correlated many times with ambient monthly temperatures.
Seasonal change in skin disease was reported in Nepal.

45. According to research the metabolic and temperature
response to mild cold were investigated in summer and
winter in a moderate oceanic climate. The average metabolic
responses during cold exposure were significantly higher in
winter as compared to summer.
Fast changes in temperature are probably may produce a
number of physiological changes in the body. Rapid drops
may affect blood pH, blood pressure, urination volume and
tissue permeability.
Also, platelet counts in healthy subjects were significantly
higher in summer than in winter. Hormone secretions are
periodic variation release that may be influenced by seasonal
variation, same is observed in case of liver function and
serum uric acid and Triglycerides levels.

46. Some study suggests that systolic and diastolic blood
pressure values differed significantly across the four seasons
and in these seasons, due to moderate cold, heat and rain the
season having common character are most convenient and
not harmful to body and drugs.
Therefore the evacuation therapy like emesis etc. are
stopped in season ending with early winter, summer and
rainy season except in case of emergency.
In emergency therapy should administer carefully after
modifying the seasonal effects by artificial means.

47. SUMMARY AND CONCLUSION :-
Thus, recent researches showed the effect of season on
healthy as well as diseased person. But there is lack of
knowledge about preventive aspect.
Acharya Charaka not only mentioned the preventive
aspect but also mentioned how treatment should be given
considering seasonal effects.
This indicates that Acharya was aware about the
variations in physiological parameters in various seasons.

48. Due to change in global environment due to global
warming, there are marked seasonal variations observed in
India and abroad. Heavy rainfall with extended Monsoon
season or vary short duration of Rainy season with scanty
rainfall as described by Acharya as Atiyoga and Hinyoga
respectively are observed nowadays.
Thus, the seasonal regimens prescribed by Acharya if
followed cautiously and strictly will surely prevent many
diseases known to be produced due to lack of seasonal
homologation.
This marks the importance of Acharyas thoughts which
are still applicable and useful for the preventive perspective
of Ayurveda.

49. As qouted by Acharya Dridhbala in Ch. Si.12/53;
धचकर्त्सा वञ्ननवेिस्य सुस्थातुरदहतं प्रतत ||
The science of therapeutics, compiled by Acharya
Agnivesha for the well being of the healthy and the ailing.
We could say that the earlier purpose is well served by
the means of Ritucharya.
