“Rasa” (Samskrit : रसः) is one among the five qualities of dravya (द्रव्यम् substance). The term “rasa” means taste or the perception of taste. Also the guna (गुणाः quality) of the rasanendriya (रसनेन्द्रियम्) is known as rasa (the rasa dhatu among the saptdhatus is distinct from this rasa) Rasas in dravya (substance) are known by their effects in our body.
व्युत्पत्तिः॥ Etymology
रस्यत आस्वाद्यत इति रसः | (Char. Samh. 1.64)[1] rasyata āsvādyata iti rasaḥ | (Char. Samh. 1.64)
Meaning: Rasa means which can be perceived by the tongue or that which can be tasted.
रसभेदाः ॥ Types of Rasas
There are shadrasa meaning six in number:
रसाः स्वाद्वम्ललवणतिक्तोषणकषायकाः| षड् द्रव्यमाश्रितास्ते च यथापूर्वंबलावहाः (Asht. Hrud. 1.14-15)[2] rasāḥ svādvamlalavaṇatiktoṣaṇakaṣāyakāḥ| ṣaḍ dravyamāśritāste ca yathāpūrvaṁbalāvahāḥ (Asht. Hrud. 1.14-15)
Meaning: Madhura, Amla, Lavana, Katu, Tikta and Kashaya are 6 types of rasa which are present in substances. These rasas are in decreasing order of providing strength to the body.
Svadu/Madhura (स्वादु / मधुरः । sweet), Amla (अम्ल । sour), Lavana (लवणः । salty), Katu (कटुः । pungent), Tikta (तिक्तः । bitter) and Kashaya (कषायः । astringent) are the 6 types of rasa. According to Ayurveda acharyas these rasas provide strength to the body when consumed through diet and medicines. Although all these rasas provide strength, not all of these have equal ability to provide strength. Acharya Vagbhata states that, these rasas are in decreasing order of providing strength to the body. This means madhura rasa imparts maximum strength whereas Kashaya rasa lowest.
रसोत्पत्तिः तथा पाञ्चभौतिकत्वम् ॥ Origin of rasa and their panchabhautikatavam
Each of the 6 rasas constitutes of two mahabhutas (महाभूतानि). For every rasa those 2 mahabhutas which are dominantly found in it have been specifically mentioned by Ayurveda.[3] The dominant mahabhutas for each rasa have been listed in the table below.
| Rasa (रसः) | Dominant Mahabhutas (महाभूताधिक्यम्) |
| Madhura | Prithvi, jala(earth+water) |
| Amla | Prithvi, tejas(earth+fire) |
| Lavana | Jala, tejas(water+fire) |
| Katu | Vayu, tejas(air+fire) |
| Tikta | Vayu, akasha(air+ether) |
| Kashaya | Vayu, prithvi(air+earth) |
For manifestation of any rasa, jala mahabhuta and Prthvi mahabhuta are essential.
रस-अनुमानम् ॥ How to determine rasa
Rasas are found in dravyas (द्रव्यम् । substances). Thus, rasa of a dravya can be determined by either tasting that dravya (i.e. on contact of dravya with tongue/ sensory organ).[4] According to Darshana shastras (दर्शनानि) rasa can be determined by three modes as follows,
- Pratyaksha (प्रत्यक्षम्। Direct perception by senses)- By directly tasting a dravya
- Anumana (अनुमानम्। Inference drawn on the basis of well established relationships that are previously known to the individual)- On the basis of its effects on body after its contact and
- Aptopadesha (आप्तोपदेशः। Knowledge obtained from trusted sources like classical treatises, Gurus etc)- As described in classical treatises/books
Here mainly pratyaksha pramana (प्रत्यक्ष प्रमाणम्) is used. When any dravya (द्रव्यम् । substance) comes in contact with rasanendriya (रसनेन्द्रियम् । Gustatory sense organ or taste buds in tongue) a peculiar taste is perceived this is called rasana pratyaksha jnanam (रसनाप्रत्यक्षज्ञानम् । Rasana- tongue, Pratyaksha-direct perception, Jnana-knowledge).
अनुरसः ॥ Concept of Anurasa
Anurasa (अनुरसः) or uparasa (उपरसः) are those which are not perceived at first (contact with body/organs) but are perceived at the end or not at all. Anurasas are perceived by anumana pramana (अनुमानप्रमाणम् । inference) but can only be understood by aptopdesha (आप्तोपदेशः । ancient literature or classical treatises). For example, Ayurveda treatises have in depth description of various metals and minerals for medicinal use. In Ayurveda, the action of each of the medicinal drug is determined based on its rasa, veerya, vipaka, karma and prabhava. However, it is not possible to taste any raw metal/mineral to understand its rasa. In such cases, description of these medicinal substances available in classical treatises helps one to understand their various properties like rasa, veerya etc. On this basis madhura rasa in Suvarna (सुवर्णम् । Gold), rajata (रजतम् । Silver) is not perceived but is known by reading classical literature which is authentic source of information on Ayurveda. This type of knowledge about rasa or anurasa is said to be through Aptopadesha pramana.
विविधाः रसाः तथा तेषां गुणाः ॥ Properties of rasa
Each of the six rasas possess peculiar properties. These properties are responsible for their specific action inside body.
