Astanga Hrudaya
स्नेहे सिध्यति शुद्धाम्बुनिःक्वाथस्वरसैः क्रमात्। कल्कस्य योजयेदंशं चतुर्थं षष्ठमष्टमम् ॥ १६ ॥
oil or ghee is prepared from pure water, decoction, or juice extract used as the liquid in that order, then the quantity of Kalka (paste) should be 1/4th, 1/6th and 1/8th to that of Sneha (oil or ghee). (This means, if water is the liquid, then kalka: Sneha: water = 1:4:16; if kwatha is the liquid, then kalka: Sneha: liquid = 1:6:24; if Swarasa – herbal juice extract is used, then kalka: Sneha: liquid = 1:8:32).
