Shirodhara is a form of Ayurveda medicine that involves gently pouring liquids over the forehead (the 'third eye'). It was developed by vaidyas (practitionars of Ayurveda) in Kerala, India for use in sukhachikitsa (restorative therapy) and can be one of the steps involved in Panchakarma. The name comes from the Sanskrit words shiras 'head' and dhara 'flow'. The liquids used in shirodhara depend on what is being treated, but can include oil, milk, buttermilk, coconut water, or even plain water.
Shirodhara has been used to treat a variety of conditions including eye diseases, sinusitis, allergic rhinitis, greying of hair, neurological disorders, memory loss, insomnia, hearing impairment, tinnitus, vertigo, Ménière's disease and certain types of skin diseases like psoriasis. It is also used non-medicinally at spas for its relaxing properties. There are specialized forms of shirodhara called thyladhara, ksheeradhara, thakradhara and jaladhara.
