Shirovasthi is for the primary treatment for disorders of the central nervous system. Highly concentrated herbal oil is allowed to remain on the vital point of the head for approximately 60 -120 minutes. This therapy is the King's therapy in Ayurveda since it directly accesses the seat of Vata (the central nervous system). Therefore Shirovasthi is accounted as primary therapy since MS is a Vata disorder. But it shows effect only if high quality concentrated herbal oils are used. In “Charaka samhitha “(the authentic and ancient book on Ayurveda) the effect of this treatment is described as “unimaginably great”.
A leather hat is fixed over the head. Potentiated medicated oil (not the oil which is used for the body) depending upon the constitution and illness of a patient is allowed to remain for a specified time (time is recognized by Pulse).The foremost aspect of the whole treatment is the usage of potentiated herbal oils which are either used alone or as a mixture of 3 different kinds of herbal oils. The oil is replaced every 3 days for maximum efficacy (the oil can be used for many days because of high potentiality of herbs). It takes 3 weeks to prepare medicated oils which contain around 65 different herbs.
