When one takes these foods which are dry by nature, they are going to increase dryness in the body. Dryness, being opposite to the wetness and unctuousness of the body depletes these qualities in the body. All cells and tissues are held together by the unctuous and wet qualities. When these qualities are depleted by excessive dryness, the integrity of the body is lost. Excess dryness causes destruction of tissues leading to lowering of strength and immunity.

Effect on doshas

रूक्षं समीरणकरं परं कफहरं मतम्।भा.प्र।

Dryness quality increases vata and mitigates kapha. The quality is beneficial in handling high kapha conditions.

Unctuousness is the basic quality of kapha. When kapha increases, unctuousness and wetness will naturally increase beyond limits in the body. Increased unctuousness and wetness will naturally cause sluggish metabolism. Decreased digestive and tissue fire will lead to formation of ama, the intermediate products of food digestion. When ama is put into circulation, it causes multiple blocks in many channels and ducts of the body. This will cause accumulation of wastes and toxins in the body which will make the body susceptible for many systemic and dreadful ailments.

Effect on Tissues


Dryness quality is responsible for depletion of tissues. When dryness increases, it dries up the tissues and leads to their destruction. This quality immensely decreases the strength and immunity of an individual because these virtues depend on the qualitative and quantitative balance of tissues of the body.

Dryness also depletes and diminishes the color and complexion of the body. These virtues are dependent on the quality and quantity of nutritional juices in circulation, the rasa tissue and also the balance of tissues.

Our strength, immunity and colour also depends on the qualitative and quantitative balance of essence of all tissues i.e. ojas. Since dryness destroys the tissues, the ojas which determines all good features in us also is not formed properly making us susceptible to various diseases. Ojus, rasa tissue and most tissues are rich in wetness and unctuousness.

Effect on Excreta


Dryness quality drains the excreta. It absorbs liquidity of excreta and makes it dry. This is mainly related to faeces. Since faeces lose excessive moistness and liquidity, it becomes dry. Dry faeces are expelled with difficult. Over a period of time it results in constipation.

This principle is also applicable for other excreta i.e. urine and sweat. When there is more dryness in the body, the urination and sweating is also in less proportion. This further leads to increase of waste products and toxins in the body.
