विपाक

Introduction:

To know the action of Dravya in the body it is necessary to know the properties of that Dravya by which it performs the actions in the body. विपाक is one of the properties of Dravya. The drug action seen on the body is a resultant effect of any of Rasa, Gun`a, Veerya, Vipaaka and Prabhaava. विपाक is of three types as Madhura, Amla and Kat`u. Though their actions are similar to the respective Rasa, they are different from the respective Rasa as they become functional after the processing of Agni on Dravya.

A.H.Su.9/20

This is the definition of विपाक. After coming in contact with Jaatharaagni, transformation occurs in the constitutional configuration of Mahaabhoota of Rasas and the resultant constitutional change is called as विपाक.¹

In the process of digestion all the Rasas undergo three Avasthaapaakas i.e. Madhura, Amla and Kat`u simultaneously and the resultant change that dominates after the complete process is called as Vipaaka. Vipaaka is of three types 1. Madhura, 2.Amla, 3.Kat`u

Rasa And विपाक Relation:

Rasa	विपाक
MadhuraLavan`a	Madhura
Amla	Amla
Kat`uTiktaKashaaya	Kat`u

This is a general rule for विपाक since there are exceptions like Aamalakee is Amla Dravya and still has Madhura Vipaaka; Kulattha has Kashaaya Rasa and Amla Vipaaka etc.

Opinions about विपाक:

1. Pancha Bhautika Vipaaka–

   Su.Su.46/526
   Here Aahaara is told as Panchadhaa Vipakva and hence विपाक is considered as of five types namely Paancha Bhautika.²
2. Dvividha Vipaaka-

The three Vipaakas told earlier are further categorized into Laghu and Guru based on Bhautika domination. Madhura विपाक has Aapa and Prithvi Mahaabhoota dominating which are Guru in nature hence it is Guru Vipaaka. Kat`u Vipaaka has domination of Agni and Vaayu Mahaabhoota which are Laghu in nature hence it is Laghu Vipaaka. Amla Vipaaka has domination of Prithvi and Agni Mahaabhoota but its effects are similar to Laghu hence it is Laghu Vipaaka.

Difference between Rasa and विपाक:

Though the resultant change is named after Madhura,Amla and Kat`u Rasas, there is basic difference in them.Rasas are perceivable by Rasanendriya but विपाक is not perceivable by sense organs directly.But the effects it shows on the body are similar to those of Madhura, Amla, Kat`u Rasa.Therefore it is called as Rasaihi tulyaphalah and not merely Rasaihi Tulya.³

Effects of विपाक on Body⁴:

C.Su.26/61-62

विपाक	Effect On Dosha	Effect On Dhaatu	Effect On Mala
Madhura	Kaphakara	S`hukrala	Srushta vin`mootra
Amla	Pittakrit	S`hukranaas`hana	Srushta vin`mootra
Kat`u	Vaatala	S`hukrahaa	Baddha vin`mootra

Here S`hukra is representative of all the Dhaatu. S`hukrala indicates increase in all the Dhaatu. S`hukranaas `hana indicatesdeclining in quality of S` hukra and incapability to increase its quantity. Similar is in the case of S`hukrhaa, where quantity also affects.

Here are some examples of विपाक:

• Madhura Vipaaka- Gokshura has Madhura Rasa and Madhura Vipaaka and it increases urine, pacifies vitiated Vaata Dosha and increase Dhaatu. Godhuma has Madhura Rasa with Madhura Vipaaka and it increases Kapha and all the Dhaatu as well as Mala.
  
  Exception – Yava i.e. Barley which is Madhura Rasa Dravya has Kat`u Vipaaka and hence doesnt pacify Vaata but increases it.
• Amla Vipaaka- Chaangeree is Amla Rasa Dravya having Amla Vipaaka hence increases Pitta Dosha and Mala.
  
  Exception- Aamalakee has Amla Rasa as Pradhaana Rasa but its विपाक is Madhura hence instead of increasing Pitta it pacifies vitiated Pitta.
• Kat`u Vipaaka- Maricha has Kat`u Rasa and Kat`u Vipaaka due to which it increases Pitta; it also reduces Mala and Dhaatu.

Exception– Pork has Kat`u Rasa and still it has Madhura Vipaaka hence it doesnt vitiates but pacifies it.⁵
