Viruddha Ahara: improper combination of substances leading to incompatibility and disease

Viruddha Ahara:


The word Viruddha leads to two factors i.e. on combining two, three things, the stronger one shades or overpowers the weaker ingredients. It has been stated that in a combination of so many opposite qualities, the majority of the power packed qualities overpower the weaker qualities.


The second meaning of Viruddha indicates about the combination of two substances which are not having an affinity for each other. So far this interpretation of Viruddha is concerned, it has been applied in Ayurveda in the context of dietetics & various combinations having such affinity for each other have been discussed at length. On this basis it may be concluded that such type of Ahara or foodstuff which is composed of substances having no affinity at all may be defined as Viruddha or Viruddhahara

Simply, Ahara that which vitiates dosha and which is antagonist to the dhatu in the body is known as viruddha ahara.

In the lexicographic literature various other terms are also used such as –


Ananukula or Pratikula (Shabda Kalpadrum) –which is having an adverse effect or unfavourable

Anapayukta – which is unpropetious

Pratisiddha – prohibited

Apathya – incompatible diet

After eating raddish, garlic, basil one should not take milk because of the risk of skin disorders.

All sour liquids are antagonistic to milk.

Hot honey taken by a person induces toxicity and lead to death.

Likewise honey and ghee in equal quantity, hot water after taking honey are antagonistic.

Examples of Incompatibility/ Antagonistic (Viruddha -Aahara)


1) Veerya viruddha- (potency incompatibility) – Fish + milk

2) Sanskar viruddha- (Processing incompatibility) Heated Honey

3) Matra viruddha- (dose incompatibility) – Honey + Cow’s ghee – mixed in equal proportion.

4) Krama viruddha – Hot water after taking honey

5) Kala viruddha- (Time incompatibility) Pungent substance in summer & Cold substances in winter

6) Krama viruddha-(Order incompatibility) -Consuming curd at night.

7) Samyoga viruddha- (Combination incompatibility) – Fruit Salad / Milk+ Banana

8) Parihar viruddha (contraindication incompatibility) -Consuming cold water immediately after having hot tea or Coffee.

Definition of Antagonism of Foods:
The substances which are contrary to “deha-dhatus” (the body tissues) behave with “virodha” (antagonism) to the tissues. This antagonism may be in terms of properties of the substances themselves, combination, processing, place, time, dose etc. or natural composition.

For An Example of Antagonism of Foods:
One should not take fish with milk. Combination of both of them is madhura
(sweet); madhura vipaka, “mahabhisyandi” (creates great moisture in the tissues when the tissues are being created and it obstructs the channels), because milk has sita (cold) virya and fish has usna (hot) virya the result is
“viruddhavirya” (antagonistic in terms of potency), due to conflicting viryas; it vitiates blood and due to being mahabhisyandi, creates obstruction in channels.

Results of taking antagonistic foods:
impotency, blindness, erysipelas, ascites, pustules, insanity, fistula-inano,
fainting, narcosis, tympanitis, spasm in throat, anaemia, ama visa, leucoderma,
skin diseases, grahaniroga, oedema, acid gastritis, fever, rhinitis, genetic disorders and even death.

Measures to counteract disorders caused by antagonistic foods:
Emesis, purgation, use of medicines for pacification, and prior conditioning of the body with similar substances.

Purgation, emesis, pacification or prior use of wholesome substances alleviates the disorders caused by antagonistic food. Antagonism becomes inert due to: suitability, small quantity, strong digestive power, in young age, in persons having: unction, physical exercise, and strength.



The eighteen types of viruddha ahara mentioned in the classics like desha, kala, agni, matra, etc. are understood with the help of examples like Agni viruddha

In mandagni condition consuming guru snigdha ahara. In condition like dyspepsia where impairment in gastric, bile, pancreatic secretions are present, due to increased intake of mamsala ahara which are rich in amino acids and lipids impaired metabolism.

Satmya viruddha Person satmya with katu ushna dravya sevana consuming increased swadu sheeta dravya.

Persons habituated with rich spicy diet like pepper which causes irritation of gastric mucosa leading to increased gastric juice secretion, if increased intake of chilled soft drinks in such person’s causes constriction of gastric mucosa leading to less gastric juice secretion.

Avastha viruddha after nidra consuming kaphavardhka ahara like curd. After sleep basal metabolic rate of the body is reduced, curd which is rich in fats and carbohydrates requires more time for digestion.

The rest types of viruddha ahara are analyzed and understood scientifically in the same manner as explained above.
