Pitta dosha (पित्तम् पित्तदोषः वा)

“Pitta” (पित्तम्) literally translates to “bile” or “bilious humor. It is one of three doshas (दोषाः) that are the primary foundations of Ayurveda and more specifically one of the fundamental and unique entities in the understanding of Ayurvedic anatomy, physiology, pathology and etc. Doshas are also known as bio-energies controlling the functioning of the entire body. Some consider Pitta to be equivalent to the bile described in western science, but its properties, its physiology in sharira (शरीरम्) are peculiar and distinct and must be understood from the Ayurvedic point of view. Pitta is known as “heat” in general which is originated from the “agni” mahabhuta (अग्निमहाभूतम्). Thus Pitta represnts the Fire element inside the body which chiefly performs the function of transformation in the body. Along with other doshas, dhatus (धातवः)(tissues) and malas (मलाः), Pitta dosha carries out various other functions as well e.g. vision, skin color generation, generation of hunger, thirst and intelligence etc. Among all these functions, Digestion of food along with maintenance of body temperature is the most important function of the Pitta.

निरुक्तिः॥ Etymology

The word Pitta is derived from the root as below,

‘तप’ सन्तापे | (sush. sutr. 21.5)

Here the root word is “Tapa” (तपस्) which means to generate heat or to burn.

“Santape" (संतापे) literally means to torment, this explains the feature of pitta as that which generates extreme heat.

पित्तदोषस्थानानि॥ Sites of Pitta dosha

Even though the doshas are present all over the body, there are certain sites where there is a predominance of each dosha. Pitta dosha is generally present in the middle region of the sharira, between hriday (हृदयम् | heart) and naabhi (umbilicus).

नाभिरामाशयः स्वेदो लसीका रुधिरं रसः| दृक् स्पर्शनं च पित्तस्य, नाभिरत्र विशेषतः||२|| (Asht. Hrud. 12.2)

Meaning: Pitta is situated in Naabhi(umbilicus), amashaya(stomach precisely), sweda(sweat), lasika(lymph), rasa(correlated loosely as plasma), rudhira(blood), drik(eyes), tvacha(skin). More specifically Nabhi is the chief site of Pitta.

पित्तस्य पाञ्चभौतिकत्वम् ॥ Panchabhuta composition

All the living and non-living entities (matter in the universe) has evolved from or made up of Panchamahabhutas (पञ्चमहाभूतानि). Teja Mahabhuta (तेज महाभूतम्) or Agni mahabhuta (अग्नि महाभूतम्) which literally means the fire element , is predominant in the Pitta dosha. Thus, Pitta dosha originated from the Teja mahabhuta.

अग्निपित्तयोः आश्रयाश्रयीभावः ॥ Relationship between Pitta and Agni

Pitta dosha and Agni Mahabhuta have Ashraya-ashrayi bhava (आश्रय-आश्रयीभावः) which is a unique Ayurvedic concept that precisely states the interdependency of these two separate entities. The word Ashraya means that which “depends on” and Ashrayi means that which is “the dependent”.

Agni is present in our body in the form of pitta dosha, thus Agni works in our sharira through pitta dosha.

Agni and Pitta dosha perform similar functions like Dahana (दहनम् । digestion), Pachana(पाचनम्), and abhipravartana (अभिप्रवर्तनम् । transformation). Both of these when vitiated are managed with sheeta dravya (शीतद्रव्यम् | coolant drugs) or karma ( कर्म । procedures with cooling properties). Although there are certain similarities as well. For instance, Ghrita or ghee is excellent to pacify the aggravated Pitta dosha, but at the same time ghee is used to kindle or increase the digestive fire i.e. agni. Even though they are interdependent in certain ways, while describing “swasthya” (स्वास्थ्यम्) or complete health, they are described as separate entities stating “samadosha” (समदोषः) “Sama Agni” (समाग्निः) which means a balanced state of doshas and a balanced state of Agni is required for maintenance of “swasthya. This understanding of interdependency between the two separate entities is essential for a better understanding of the disease manifestation and prognosis which helps in the planning of management.

पित्त-इन्द्रियसंबंधः ॥ Association with Indriya

Indriyas (इन्द्रियाणि) are the sensory & motor organs through which knowledge is perceived and response in generated. ‘Indra” which means “atman (आत्मन्)” or soul experiences this knowledge. There are five sense organs “Chakshu”(चक्षु । Vision), Shrotra (श्रोत्रम्। Auditory), ghrana (घ्राणम्। olfactory), rasana (रसना । gustatory) and  Sparshana(स्पर्शनम् । tactile). Among these 5 sensory organs, Chakshu (Eye) and Sparshana / Twak (Skin) are the 2 organs where Pitta predominantly resides and controls the functions or these organs.

1. Chakshurendriya (चक्षुरेन्द्रियम्) - The eye is the seat of type of pitta known as Alochaka pitta and is responsible for the visual perception.
2. Sparshanendriya (स्पर्शनेन्द्रियम्) - Twak or skin is the seat of type of pitta known as Bhrajaka Pitta and is responsible for the maintenance of body temperature, provides luster to the skin, and helps in the sensation of touch.

Gunas/ Attributes

(Char.sutr.1.60) (Asht.hrud.sutr.1.11) (Sush.sutr.42.7)

1. Sasneha - slightly Unctousness or oiliness  
2. Tikshna - Teekshna means the Sharpness or the penetrating property of pitta dosha
3. Ushna -Ushna or Hot or to generate heat. The maintenance of body temperature which is one of the functions of Pitta dosha is because of this quality.
4. Laghu -Laghu means Lightness that is present in Pitta dosha due to its origin in Teja Mahabhuta. This property is essential for a physician while prescribing treatment.
5. Vistra -pitta dosha in its natural form has a bad Odour.
6. Sara - Sara means mobility, the property which is unstable in nature and has the capacity to put things in motion.
7. Drava- Drava means Fluidity or liquidity which explains the form of pitta dosha.
8. Peeta - Peeta means Yellow, here it directly implies to the color it has, which provides other entities which it comes in contact with.
9. Vishada -Vishada means cleansing property that is related to the Agni mahabhuta. This property stated the cleansing nature of pitta dosha.

The Gunas or the properties of doshas are important for the purpose of diagnosis and treatment. The dravyas or the drugs that have properties opposite to the pitta dosha are used for pacifying it and the properties similar to that of pitta dosha cause vitiation.

Pathological state of Pitta dosha

Factors affecting pitta dosha

(Sush.sutr.21.20) (Asht.hrud.sutr.1.8) (Asht.hrud.sutr.12.21) (Asht.hrud.nida.1.16)

There are certain factors that are responsible for the vitiation of Pitta dosha. Change in season, age and etc cannot be avoided, although external factors like diet and lifestyle can be controlled to avoid vitiation of pitta dosha in an individual. Any individual with dominant pitta dosha can avoid the below-mentioned external factors for a balanced state of dosha in the body.

Natural Factors

1. Season - Pitta dosha gets naturally accumulated in Varsha rutu (monsoon), undergoes the Prakopa stage (vitiation)  in Sharada Rutu(autumn), and gets pacified in Hemanta rutu (early winter).
2. Age - Pitta dosha is dominant during middle age (appx 40-60 yrs)
3. Circadian rhythm - Pitta gets vitiated during midday and night.
4. Stage of digestion - During “Jiryateanne‘ (mid-digestion) the pitta dosha is id dominant

External factors

1. Diet and lifestyle - Food that is dominant in Katu(pungent), Amla (sour), and lavana (salty) rasas(tastes) causes aggravation of the pitta dosha
2. Emotional - Krodha(anger), Shoka(grief) and Bhaya (fear) vitiate the pitta dosha and vice versa.

Basic aspects of management of vitiated Pitta dosha

(Char.sutr.20.16)

Dravyas which are predominantly in Madhura(sweet), tikta(bitter) and kashaya(Pungent) rasas (taste precisely) which have Sheeta guna or cooling property are used for the treatment of Pitta dosha diseases. Also, the Panchakarma therapies like Virechana(purgation), Snehana(administration of oil, ghee, etc), parisheka() and Abhyanga(massage) must be carried out with the drugs having the above said properties, with appropriate dosage and time of administration.

Virechana or purgation is considered the best treatment for the treatment of Pitta dosha disorders or imbalance. Acharya Charaka explains this with the help of a metaphor, stating the Pitta dosha when pacified in the amashaya itself which is the seat of the pitta dosha the other organs afflicted with the Pitta get managed as well, similarly, the fire chamber cools down when the fire is extinguished.
