Method of Administration of Bhallatak Rasayan

  • Is done in the month of Sahas or Agrahayana (November-December) or Sahasya, i.e Pushya  (December-January),
  • It is administered to a patient after his body has been smeared with cooling, unctuous and sweet herbs. (This is because, Bhallataka is very hot in nature and may cause excessive burning sensation in the patient).
  • In the beginning, 10 fruits of Bhallataka should be well boiled in 8 parts of water.
  • After boiling, when 1/8th of water remains, it is filtered, added with milk and given to the patient after his mouth has been smeared with ghee.
  • Ten fruits should be added every day by one fruit till the number becomes thirty and thereafter, it should be decreased by one fruit per day till it reaches the original number – ten.
  • It should not be further increased because thirty fruits of Bhallataka is the maximum dose.
  • Following this procedure, one thousand Bhallatakas can be administered.

Pathya – Recommended diet

  • After digestion, the person should take the rice of Shali or Shashtika along with milk and ghee.
  • After administration for a few days, the person should take milk only twice per day. (Milk acts as a coolant and will take away the hot effect of Bhallatak).

I know its very hot or pungent in original. But i need original one , i know how to dilute it or use it. But tell me how to extract it or which company sell that original , rare bhilawa oil.
