Astanga Hrudaya
द्विगुणं योजयेदार्द्रं कुडवादि तथा द्रवम् । पेषणालोडने वारि स्नेहपाके च निर्द्रवे ॥ २३ ॥
In the absence of dry herbs, wet herbs should be used in double quantities. In the units of measurement such as Kudava etc. For grinding, dissolving, or preparing a Snehapaka where no liquid is explicitly mentioned, water should be used by default.
