Gandusha is a procedure of holding any liquid in the mouth to its full capacity without any movement inside. This is one the treatment which is commonly used in Urdva jatrughatha rogas and Mukha rogas (Head and Neck diseases and Oral cavity disorders). Gandusha is also explained as one of the procedure in Dinacharya (Daily regimen).

The action of Gandusha can be explained in both local and systemic action. The action of Gandusha exerts increased mechanical pressure inside the oral cavity. The chemical constituents of the drug which is present in the liquid stimulates pressoreceptors that are present in the mouth. These pressoreceptors sends signals to salivary nuclei. As a result parasympathetic nervous system and motor fibres in facial and glossopharyngeal nerves helps to increase the output of salivary secretion which predominantly contains water and removes metabolic waste present in the oral cavity.
Gandusha will helps in secretion of salivary amylase present in saliva and lingual lipase secreted by lingual gland present at the dorsum of the tongue which initiates the digestion of carbohydrates and fats respectively.
The warm medicated liquid with its active ingredients and chemical constituents irritates the oral mucosa and increases the vascular permeability. Therefore the lipid soluble drugs get rapid absorption into systemic circulation as the mucosal layer, inferior to the sublingual layer is thin and highly vascular.
