Rasa kalpas are popular during past and present because of lesser dosage palatability and quickness in combating disease pathology. For advising rasaou½adhas there is no need of examining in detail the do½as,dÀ½ya, avasth¡,k¡la, de¾a,and vayah and just by assessing symptoms and by yukti they can be advised.

Pharmaceutics of rasa¾¡stra

Discussion…

All the processes of rasa½¡stra are basically chemical reactions done at precisely controlled temperatures. If we study the yantra prakarana of Rashastra books various authors depicted various yantras to control the reactions as per the requirements for e.g. Damaru yantra, P¡tanayantra, Kacchapayantra, I½tik¡ yantra and etc.

Discussion…

Yantra may be defined as a plan or a design or a method or software with which a required task is accomplished. So it s not only physical equipments ’but also the planning the yantra means. In other words yantra is hardware and tantra is software part of a program. So both of them are important for a desired activity. .

Pottali kalpanaIdea behind the conception of pottali:

Vistaritasya vastuno alpibhavan¡m pottam pottam lati g»hn¡ti iti pottali.

Word pottali means to minimize, to concise and to make compact.

P¡ka of Pottali : Stainless steel vessel is taken and arrangements are made such that a rod can be kept on the walls of the container to hang the pottali.

Pottali kalpana-Procedure

The total pottali p¡tra is kept in sand bath and a v¡luka yantra is made.

Now to the container ¾uddha Gandhaka is added and total v¡luk¡ yantra is heated.

See that temperature should be given to such an extent that only sulphur starts melting. Note the temperature of the molten sulphur which should be 111O C 120– O C.

Now immerse the pottali in to the molten sulphur and tie the pottali such that it is immersed in molten sulphur with out touching the base of the vessel.

exposed to heat with a gradual step rise ie 15O C for every 1 hour till it rises to 210O C in 4 hours.

Later the pottali is removed when the molten sulphur temperature is 111O C and after cooling (sv¡ngasheeta) the silk cloth is removed carefully and excess sulphur is scraped out with sharp edge blade.

The pottali attains metallic luster and giving metallic sound when hit with a metal object.
