Before starting with Panchakarma treatment, Snehakarma (oiling treatment) and Swedana (sweating treatment) is done. Panchakarma is a method of expelling the imbalanced Doshas out of the body. Before they are expelled either by oral or anal route, the imbalanced Dosha needs to be softened, mobilized and brought into the gastro-intestinal tract for easy evacuation of imbalanced doshas. This is achieved by Snehakarma and Swedakarma. This chapter, the 13th of Sutrasthana of Charak Samhita explains Snehakarma in full detail.
Once upon a time, Lord Punaravasu was sitting with scholars. Agnivesha put forth a few doubts before Punarvasu, for the sake of the well being of the universe.

Ghrita – Ghee,
Taila – oil,
Meda (Vasa) – muscle fat and
Majja – Bone marrow
These are the best fatty substances of all. Among them ghee is the best oily substance, because of its power to assimilate effectively the properties of other substances. (Samskara Anuvartana)
Medicinal properties of ghee
Ghee balances Pitta and Vata,
it is conducive to Rasadhatu, Sukradhatu (semen) and Ojas. It has cooling and softening effect on the body. It adds to the clarity of the voice and complexion.

If one suffering from diseases of Kapha imbalance or from a disease during the course of the winter, if he is administered with oleation during evening, he will suffer from anaha (bloathing), anorexia (aruchi), colic pain and anemia. [20-21]
Anupana for unctuous substances
Ghee is to be taken with the Anupana of hot water,
oil with anupana of Yusha (vegetable soup),

Sneha Pravicharana combinations
Sneha Pravicharana – Classification of fat preparation combinations:
Oily preparations are of 63 types depending on their association with the drugs having six rasas (tastes) in isolation or variant combination. Together with the simple (unmixed) ones, these substances are of sixty four types. A physician, being expert with the habit, seasons, diseases and individual requirements should accordingly administer these sixty four types of preparations of fats and oils. [27-28]

Minimum period is 3 days.
Maximum period is 7 days. 
General indications for fat / oil therapy
Oleation therapy in general is prescribed for those who are to be given Swedana (sweating treatment) or Panchakarma therapy,
those who have roughness in the skin,
those suffering from diseases due to Vata imbalance;
those who indulge in physical exercise, wine and women,
and those who suffer from mental strain.
Contra- indications for fat administration
Oleation therapy should not be administered to such of the patients who are
eligible for Rukshana(drying therapy)
to those in whom Kapha and Medas (fat) are aggravated,
those with Kapha symptoms like excess mucus secretion from mouth and anus,
those whose power of digestion is continuously weak,

those having aversion to food, those suffering from vomiting,
abdominal diseases,diseases due to improper digestion as well as metabolism,
those afflicted with Gara type of poison (chronic diet-poison),
the weak, emaciated, those having aversion to the intake of unctuous substances,
those intoxicated and those being administered inhalation and enema therapies.
If oleation therapy is administered to such persons, they re likely to fall victims of disastrous complications[53-56]
Signs and symptoms of incomplete oleation
Hard and dry stool, derangement of Vayu, weak digestion power, roughness and dryness of the skin- these are the signs of under oleation 
Signs and symptoms of proper oleation
Evacuation of the flatus, good digestive power, untucous and soft stool, tenderness and smoothness of the body- these are the signs of proper oleation.
Signs and symptoms of over oleation
Paleness, heaviness, stiffness, stool indicative of indigestion, drowsiness, anorexia are the signs of over oleation.
A day preceding to the administration of oleation therapy, one should take food in proper quantity.
The food should be liquid, hot and Anabhisyandi (that does not obstruct the channel of circulation / that which does not leave a coating on body channels).
It should neither be too unctuous nor a mixture of two opposite qualities (hot and cold).
When hungry, one should take alleviation (samshamana) type of oleation therapy in low doses, during lunch hours.
Samsodhana type of oleation therapy should be administered when the food taken in the preceding night has been well digested.[60-61]
Management during oleation
While under the oleation therapy, one should always use hot water,
one should not sleep during day time
one should not suppress urges of motion, urination, flatus eructation, etc.
one should avoid physical exercise, loud speech, anger, anxiety, cold and sun,
one should lie down or sit in a place well protected from wind.
Even after the completion of the course of oleation therapy one might be required to take some more unctuous substance of homologous qualities,
Adoption of wrong regimen during the course of oleation therapy will result in serious complications[62-64]
Test to identify Mridu Koshta
Therapeutic test for the diagnosis of Mridu Koshta (laxed bowel):
A person with Mridu Koshta (laxed bowel), is properly oleated by taking unctuous substance for three consecutive nights and one with Krura Koshta (costive bowels) for seven consecutive nights.
People with mridu koshta would have purgation with following –
Sugar candy, sugarcane juice, mastu(whey), milk cream from the curd, curd, payasa(milk preparation), gruel made from sesame, rice and black gram, ghee, juice of Kashmarya (Gmelina arborea Linn), Haritaki – (Chebulic Myrobalan), Amla, Bibhitaki (Terminalia belerica Roxb), raisins and Pilu (Salvadora persica Linn), even hot water or fresh wine.
But these can not produce purgative effect for those with Krura Koshta (costive bowel) because their intestine is too much dominated by Vata, Purgation is easy for those with laxed bowel, because their Grahani is dominated by Pitta and is least affected by Kapha and Vata. [65-69]
Side effects of oleation and its management
Unctuous substances taken by a person with Pitta imbalance in duodenum and having strong digestive power, gets digested quickly by virtue of the power of the digestive fire.
Strong digestive fire, having consumed the heavy dose of unctuous substance displaces the Ojas and aggravates the thirst with complications.
Even very heavy food is not enough to satisfy the digestive fire excited by oleation.
In the circumstances, unless he takes recourse to cold, water, the patient may die as a serpent lying in the midst of a heap of wood dies with the fire of its own poisonous breath.
If a patient gets thirst due to indigestion of the unctuous substances taken, the physician should administer vomiting treatment (Vamana)
The patient should again be given Vamana after being given cold water and unctouous food.
Unmixed ghee should not be taken in the event of the domination of Pitta specially when Pitta is associated with Ama.
Ghee taken in this condition brings about paleness (Jaundice) in the body and may prove to be fatal by impairing the consciousness.
If oleation therapy is not administered properly, drowsiness, Nausea, Acute constipation, Fever, stiffness, Unconsciousness, spreading type of skin disease, Pruritus, Paleness, Oedema, Piles, Anorexia, Thirst, Obstinate abdominal diseases due to the malfunctioning of the intestine including duodenum, Stillness, Suppression of speech, Colic pain and diseases due to improper digestion and metabolism will occur.
In that case Vamana, Swedana (sweating) or fasting (till the previous intake of Unctuous substance gets digested) is prescribed.
Purgation may also to be administered with due regard to the strength of the disease depending on individual cases. Complications arising out of the inappropriate oleation may also be neutralized by the intake of Takrarista (Charaka Chikitsa 14:72-75), unctuous drink and food, urine, Triphala Churna [70-78]
The oleation therapy gives rise to many complications, if it is administered at inappropriate times or is not taken in the proper dose or taken in excess or (even if taken properly but) followed by improper regimen.
Virechana (Purgation) is to be administered three days after the completion of the oleation therapy. During food prescribed during this interval of three days, the patient should take unctuous liquid and hot porridge together with meat juice.
The Vamana (vomiting treatment) is to be administered one day after the completion of the oleation therapy. The food prescribed during this interval of one day is the same as indicated in the preceding verse.
The regimen prescribed in connection with the purgation are to be followed with regard to the alleviation type of oleation therapy also.
Indications for the administration of fat preparation
Unctuous preparations rather than pure unctuous substances are to be prescribed for persons who have aversion of taking unctuous substance, those who are in the habit or regularly taking, unctuous substances, wine, those with Mridu Koshta (laxed bowels) and those who cannot resist to physical strain. 
The meat juice of Lava (Common quail), Tittira (black partridge), Mayura (peacock), Hamsa (swan), Varaha (Pig), Kukkuta (red squr fowl), Go (Cow), Aja (Goat), Aurabhra (wild sheep) and fish are useful in oleation.
The drugs required to be mixed with meat juice are
Yava – Barley (Hordeum vulgare), Kola( Zizyphus jujube Lam),
Kulattha(Dolichos Biflorus Linn), Sugar candy,
Crystal sugar, Dadima – Pomegranate, Curd, Sunthi(Zingiber officinale Rosc), Pippali – Long pepper fruit – Piper longum (piper longum Linn) and Maricha – Black pepper fruit – piper nigrum (Piper nnigrum Linn).
If sesame seeds together with unctuous substances, Phanita (A preparation of sugar cane), Krishara (a type of gruel) added with sufficient quantity of unctuous substance and Kambalika (sour milk mixed with whey and vinegar) prepared with sesame seed, are taken before meals, they are useful in oleation.
One having drynesss should take Phanita (a prepration of sugar cane), ginger juice and oil together with wine.
After they have been digested he should take his meal with minced meat.
A person with Vata body type can be oleated by taking oil, together with the upper portion of wine, muscle fat, marrow milk and Phanita (a preparation of sugar cane).
One gets oleated by taking warm milk fresh from the cow mixed up with sugar and unctuous substance or cream of the curd along with Phanita.
Pancha prasritaki Peya – type of gruel prepared with milk and black gram and added with unctuous substance in sufficient quantity oleates immediately.
Pancha prasritaki Peya is prepared of ghee, oil, muscle fat, marrow and rice- Prarita(96 g) of of each. This is prescribed for one in need of oleation therapy.
Juice of pork made unctuous by adding ghee and salt, if taken properly twice a day oleates immediately.[83-90]
Specific Contra- Indications of Substances used in oleation Therapy
One suffering from spreading type of skin disease, oedema and obstinate urinary disorders should not use meat juice of domestic, marshy and aquatic animals, sugar candy, curd, milk and sesamum seeds.
If necessary, such patients should be oleated by means of ghee duly prepared with therapeutically useful during or with Pipali – long pepper, Haritaki and Triphala.
A physician should prepare unctuous drink with the juice of Raisin, and Amalaki (Emblica officinalis Gaertn), sour curd, ginger, long pepper and black pepper. By taking this, one gets oleated.
The medicated ghee best suited for the purpose of oleation therapy is to be prepared with the decoction of Barley, jujube, horse gram, Alkalies, Wine, curd and ghee prepared out of milk. [91-94]
Oleation therapy in genital disorders
Therapeutic preparation for oleation in the treatment of diseases of the female genital tract and semen is to be made with oil, marrow, muscle fat, ghee and the decoction of Badara – Zizyphus jujuba Lam, Triphala. 
Sadya Snehana – Simile
Sadya Snehana – Simile regarding the effect of quick oleation:
As a cloth absorbs certain amount of water but oozes out the water in excess, so the oleation theraphy used just in proportion with the digestive powder gets digested (that is, it is ineffective for the purpose of oleation);
It oleates only when it is administered in excess. Or as water poured on a cold earth pot in quick succession oozes out after slightly saturating the latter, so, oleation therapy administered in quick succession in a day, goes waste without oleating properly. [96-97]
Salt in Sadyo Snehana
Role of salt in Sadyo Snehana – quick oleation:
Unctuous drink prepared with salt oleates an individual instantaneously because salt is by nature Abhisyandi (that obstructs the channel of circulation), unctuous, Sukshma (that passes though subtle channels), hot, Vyavayi (which gets digested only after its absorption and pervasion in the whole body).
Routine for administration
Routine for the administration of different therapeutic measures:
Oleation therapy is required to be administered first; then sweating therapy is to be applied; finally elimination therapy is to be administered after the administration of oleation and fomentation.
To sum up:-
Lord Punarvasu has described in response to the question, the various types of oleation, the procedure for oleation, all the related complications and the preparations of various drugs useful for this therapy.
Thus ends the thirteenth Chapter on “Oleation” of Sutra section of Agnivesha’s work as redacted by Charaka.
