BAHIRPARIMARJANA IN INDIAN FESTIVALS
India, the land of diversified traditions and practices has various methods of celebrating festivals. Festivals are the essential part of everyday life. Almost all the Indian fests have been not only the occasion for being harmonious and keep united socially, understand the essentials of mythology and spiritual lightning. Par from these it has rational view of maintaining ones health throughout the year.
Manu dharma Shastra says:
A¥ÉåprÉÉã aÉëÎljÉlÉÈ ´Éã¹È aÉëÎljÉprÉÉã kÉÉËUhÉã uÉUÈ A¥ÉåprÉÉã aÉëÎljÉlÉÈ ´Éã¹È aÉëÎljÉprÉÉã kÉÉËUhÉã uÉUÈ || A¥ÉåprÉÉã aÉëÎljÉlÉÈ ´Éã¹È aÉëÎljÉprÉÉã kÉÉËUhÉã uÉUÈ | A¥ÉåprÉÉã aÉëÎljÉlÉÈ ´Éã¹È aÉëÎljÉprÉÉã kÉÉËUhÉã uÉUÈ |

One who reads treatises are better than the one who knows about dharma. One who masters meaning of treatises is better than the one who only reads. One who is Jnani or scholar is better than the one who masters it but apart from these entire one who practices it is the best. Therefore understanding the objectives behind every practice is now needed. Here are some of festivals which have been systematically placed for everyone to practice and celebrate for the achievement of complete health.
UGADI -This is the New Year for all Hindus. It occurs during Vasantha rutu, kapha prakopa kala. Abhyanga with taila is said to be done compulsory as snehana karma followed by taking bath with the water put in with neem leaves and intake of neem leaves and jaggery which are kapha chedakas.
DEEPAWALI -The trayosdashi day is meant to keep the water ready for the next day i.e narakachaturdashi .on this day the abhyanga karma before sunrise is been in practice. In some southern regions even sugandha dravyas are used for lepana and then followed by snana.This festival is during the sharath –hemantha sandhi and so prepares our body to get ready for next upcoming winter season wherein kapha chaya may take place.
RATHASAPTHAMI- This is also one of the festivals during vasantha rutu wherin the practice of keeping the leaves of Arka (Calotropis gigantea) on shoulders and performing snana karma is in practice. The kapha shamana is again foreseen here.
DASARA -A 9 day festival and devi pooja as a ritual.in some southern parts of India the leaves of shami is used to in water to take bath. This fest is in sharath rutu and has a concept of pitta shamana during sharath ruthu.
SANKRANTHI -This festival during the month of January is in hemanth-shishira sandhi kala where the winter is along with scorching sun (beginning of uttarayana kala) adding up to more dryness .The custom of tila taila abhyanga and also intake of tila and jaggery makes the body acquire snehana and maintain the state of doshas.
NAGARAPANCHAMI - In certain parts of Karnataka during this festival which is around the month of august i.e varsha rutu the custom of milk poured for rituals on the god (naga) is also poured on the back and drops of it is put into the eyes. Here godugdha which is a peeyusha as sheetha veerya balances the vata prakopa due to varsha rutu especially in the region of akshi.
TULASI POOJA - After deepawali on the next day of tulasi pooja the amalaki (emblica officinalis )which is used for pooja is then crushed and used for bath in some parts of northern Karnataka. This is again for tridosha shamana and to give alpa snehana to the skin which is rough and dry.
HOLI -The festival of colours where the natural colours made of flowers of tesu and palasha. Ancient India was fully aware of the benefits of the fragrant natural colours for our skin and health and also there therapeutic value. The ingredients of Gulal were purposely chosen for their emollient qualities. In Vrindavan, Holi is still played with actual flower petals chosen for their fragrance and colour such as rajnigandha and rose Red Sandal Wood Powder / Raktachandan / Lalchandan (Pterocarpus santalinus) has a beautiful red colour, is extremely beneficial for the skin and is used in face packs, etc. This can be used instead of Red Gulal Dry red hibiscus flowers in shade and powder to make a lovely red colour. To increase the bulk add any flour to it Sinduria, called Annato in English has a water chestnut shaped fruit which contains lovely brick colour red seeds. These yield both dry and wet colours. Crush the berries (fruits) of the Indigo plant and add to water for desired colour strength. In some Indigo species the leaves when boiled in water yield a rich blue.Red hibiscus flowers soaked in water overnight give a red which also has medicinal value. The Palita Madar / Pangri / Indian Coral tree/ (Erythrina indica), found commonly in coastal regions, has large red flowers. Soak the flowers in water overnight. Boil wood of Madder Tree in water for a deep red.this festival celebrated during start of vasantha rutu gives more glow .
On the day of homas or yajnas the gomootra or pancagavya sprinkled over the body and the place around is also a sort of bahirparimarjana karma.
Thus here is a view of concept in our festivals only regarding bahirparimarjana karma as a ritual to be performed according to customs, regions and seasons. Therefore no practices or traditions given by ancestors are untrue until and unless it is given a superstition picture.

PHARMACODYNAMICS AND PHARMACOKINETICS IN AYURVEDA
• Pharmacodynamics—what drug does to the body??
• Pharmacokinetics----what body does to drug??
That means…
• Physiological & biochemical effects of drugs & their mechanism of action at macromolecular/a sub cellular/organ system level is PD.
• Movements of the drug in & alteration of drug by the body includes ADME, binding/localisation/storage, biotransformation & excretion of the drug is PK.

(Study of props) (Study of effects)
The pharmacological , toxicological & clinical efficacy of a drug are attributed to 5 qualities of a drug broadly classified as rasa ,guna,veerya,vipaka & prabhava.the pharmacodynamic & kinetic actions of ayurvedic drugs (single & compound ) are difficult to explain in terms of modern pharmacology. It is not the single chemical entity as in case allopathic drugs, acts as a receptor & elicits a response. Moreover the drug therapy is not generalized as ijn the case of allopathic drugs. The drug selectivity is according to doshas and to see the panchabhouthik compatibility of the drug & individual. Classification of drugs into mrudu, madyama & teekshna is an eye-opener to modern therapeutics on the rationale of selection of drugs for the treatment of various diseases.

Concept of Panchamahabhoothas
q The PANCHAMAHABHOOTHA theory is important as Medicinal chemistry is for modern medicine.
q “BHOOTHA” is defined as the minutest matter which will prove its existence through certain charecteristic features or it is the factor which produces all the organic and inorganic materials. ( pÉÔ xɨÉrÉÉqÉç )
q Vaisheshikas explained on the basis of Paramanu & trisrenu.
q Sankhyas proved it on basis of Pancha tanmathras & mahabhuthas.
q PMB’s related to elements H,O,N,P,S,C.etc
q Panchatanmatras means the physical properties of matter while Panchabhuthas are indicators of chemical properties of atom along with physical properties. Therefore PTM’s have horizontal expansion in periodic table while PMB’s have linear/ vertical expansion like groups in periodic table.
q Sthavara and jangama act as good medicines.
Three kinds of activities
v Bhutatma –activity in the micro matter.
v Jeevatma– activity in organic matter.
v Paramatma—activity in the galaxy.(imperceivable.)
Ayurveda describes the dravya on the basis of bhootha predominance in it. The QSAR (quantity structure activity relationship) of a drug is quite similar to pharmacological action of dravya resulting from its panchabhouthik configuration.
Concept of Samanya,Vishesha,Samavaya.
- Similar properties enhance qualities. (ekavrutthi and ubhaya vrutthi)
- Opposite properties reduce or the most powerful will overcome the others.
- Factors involved are samyoga,samskara desha ,kaala.
- Dravya samanya,guna samanya,karma samanya.
- Athyantha samanya,madhya samanya,eka desha samanya.
- Dravya vishesha,guna vishesha,karma vishesha.

Basics of Ayurveda
Pharmacology
The materia medica of the Ayurveda, composed of the five basic elements, has been categorized according to the derivatives o f these elements. They include: taste (rasa), potency (virya), taste of the digestion product (vipaka), properties (guna), specific properties (prabhava) and action (karman).
Taste (rasa) is six fold: sweet (madhura), sour (amla), salty (lavana), sharp (tikta), bitter (katu) and astringent (kasaya). Each taste is composed of two of the five elements. The condition of the food substances after digestion is also expressed in terms of taste (vipaka), however it can only be sweet, sour or sharp.
The properties (guna), are grouped in 10 pairs, each one complementary to the other: heavy and light, cold and hot, fat and dry, slow and sharp, stable and labile, soft and hard, clear and slimy, smooth and raw, fine and massive and viscous and liquid.
The potency (virya) of a drug is defined as its capability to express its property. Sometimes, potency is grouped in the same way as the property, but for practical reasons, it is usually expressed in terms of hot (ushna) and cold (shita).
The specific property (prabhava) distinguishes two drugs that have the same taste, taste after digestion and potency. This might be due to the composition of the drug or the location in the body where the drug acts.
Finally the action (karma) of a drug on the body is expressed in terms of the three doshas. A drug can increase or decrease the vata dosha, the pitta dosha and the kapha dosha.
The drugs used in Ayurveda are made by several processes from vegetable and mineral raw materials. Mostly plant alkaloids are the active ingredients.
Concept of DRAVYA
- Seat for rasa guna virya and vipaka.
- Medium of existence.
- Vyvasthitatwa (stability)
- Nityatwa (eternity)
- Swajaati avasthana (geno-specificity)
- Panchendriya grahyatva(perception)
- Ashrayatva (host for properties )
- Arambha samarthya(initition of action.)
- Sastra pramanya (classical references)
- Kramaapekshitatva(degree of maturity)
- Ekadesha sadyatva (utility of part used)
- Taratama yoganupalabdhi( avail for grading)
- Vikalpa samarthya (possibility of pharmaceutics)
- Pratighatha samarthya (malleability )

As mentioned earlier also every thing in this universe are composed of panch mahabhoot hence rasa are also no exception to it.
Rasa plays a very important role in body therapeutically and also in diagnosing a certain disease. It has a great significance in determining the vata, pitta and kapha’s involvement in the actual cause of a disease. As it has been know to you that any kind of vitiation of dosha causes disease in body. Hence excess of in take of certain rasa or deficiency of rasa causes imbalance in are tridosha.

Conclusion:One should not advise about the drug based on its rasa b’coz even when rasa of drugs is similar actions may differ.
Vipaka
When we eat or drink a substance it comes in the contact with jathar Agni (digestive fire). If the jatharagni is in its normal state it is able to digest (pachana) the substance eaten. During this digestion the food undergoes many bio transformational changes. In this process of paak (physiological condition of digestion) due to different degrees of digestion, the transformation of rasa takes place. This changing of rasa of the substance into a certain similar or dissimilar rasa is called vipaka. After completion of digestion, the substance or the food ingested would produce certain action by which we can know the process under which the substance has undergone. Hence vipaka is judged by anumana (inference made after observation). The effects of vipaka commences after the full digestion is completed. These vipaka are of there types.
