Hour 59 Ayurveda – Tastes & Health I

Shad Rasa (The Knowledge of Six Tastes) Part 1

What is Rasa?

1. In Ayurveda, ‘Rasa’ refers to the ‘taste or flavour’ of a substance.
2. It is the initial sensory experience that is perceived by the tongue when a substance is consumed.
3. Rasa is considered one of the most essential aspects of food and herbs, as it directly influences the balance of the Doshas (Vata, Pitta, and Kapha) and impacts the overall health and well-being of the individual.
4. Rasa is more than just a taste in Ayurveda, it has therapeutic properties, determining how a substance will affect the body and mind.
5. The Shad Rasa (six tastes) are linked to the PanchaMahabhutas (five great elements) and play a crucial role in maintaining equilibrium within the body.

Types of Rasa

1. Sweet (Madhura)
2. Sour (Amla)
3. Salty (Lavana)
4. Pungent (Katu)
5. Bitter (Tikta)
6. Astringent (Kashaya)

These ‘six tastes or Shad Rasa’ in Ayurveda, are fundamental to understanding the impact of diet on the body and mind.

1. Relationship between Shad Rasa and Doshas :

Each taste affects the Doshas in a specific way due to its elemental composition:

1. Madhura (Sweet): Composed of Prithvi (earth) and Jala (water). It balances Pitta and Vata but aggravates Kapha. Sweet taste provides nourishment, strength, and calmness.
2. Amla (Sour): Made up of Prithvi (earth) and Agni (fire). It increases Pitta and Kapha but reduces Vata. Sour taste stimulates digestion and appetite.
3. Lavana (Salty): Consisting of Jala (water) and Agni (fire). It pacifies Vata but increases Pitta and Kapha. Salty taste enhances digestion and softens tissues.
4. Katu (Pungent): A combination of Agni (fire) and Vayu (air). It aggravates Vata and Pitta but reduces Kapha. Pungent taste stimulates metabolism and helps clear congestion.
5. Tikta (Bitter): Composed of Vayu (air) and Akasha (ether). It increases Vata but reduces Pitta and Kapha. Bitter taste detoxifies the body and helps purify blood.
6. Kashaya (Astringent): Made up of Vayu (air) and Prithvi (earth). It aggravates Vata and reduces Pitta and Kapha. Astringent taste promotes healing and drying up excess moisture.

Note :

• Bitter, Pungent, and Astringent tastes all share Air or Space elements, which aggravate Vata and pacify Kapha.
• Sweet, Bitter, and Astringent pacify Pitta due to the absence of Fire elements and their cooling nature.
• Sour, Salty, and Pungent aggravate Pitta due to the presence of the Fire element.

2. Shad Rasa and Seasonal Changes:

In Ayurveda, the influence of Rasa changes according to the season. Different tastes are emphasized or avoided based on the need to balance the body’s natural response to environmental shifts. By aligning dietary choices with Shad Rasa and seasonal influences, one can promote Dosha balance and overall well-being.

1. Spring (Vasanta Ritu): Kapha is aggravated during spring. Therefore, tastes that reduce Kapha, such as Katu (pungent), Tikta (bitter), and Kashaya (astringent), are recommended.
2. Summer (Grishma Ritu): Pitta accumulates during summer due to the heat. To pacify Pitta, cooling and soothing tastes like Madhura (sweet), Tikta (bitter), and Kashaya (astringent) are favored.
3. Monsoon (Varsha Ritu): Vata aggravation is common during the rainy season. Tastes that pacify Vata, such as Madhura (sweet), Amla (sour), and Lavana (salty), are beneficial.
4. Autumn (Sharad Ritu): Pitta aggravates in this season, so cooling tastes like Madhura (sweet), Tikta (bitter), and Kashaya (astringent) should be consumed.
5. Early Winter (Hemanta Ritu): With Kapha accumulation starting, nourishing and warming tastes such as Madhura (sweet), Amla (sour), and Lavana (salty) are preferred.
6. Late Winter (Shishira Ritu): Vata aggravation continues in late winter. Sweet, sour, and salty tastes are again emphasized to balance Vata.

• Spring (Kapha Aggravation): Pungent, Bitter, and Astringent.
• Summer (Pitta Aggravation): Sweet, Bitter, and Astringent.
• Monsoon (Vata Aggravation): Sweet, Sour, and Salty.
• Autumn (Pitta Aggravation): Sweet, Bitter, and Astringent.
• Early Winter (Vata Aggravation): Sweet, Sour, and Salty.
• Late Winter (Vata Aggravation): Sweet, Sour, and Salty.
