Mastu

मस्तु

Mastu (whey/curd water) is the liquid that separates from the solid portion of curd. It is lighter than both curd and buttermilk. It is sour-astringent in taste, light, appetizing, and absorbent. It is beneficial in Grahani (IBS), Atisara (diarrhea), and conditions of weak Agni. The text considers Mastu a lighter alternative to Takra (buttermilk) for persons who cannot tolerate even buttermilk due to extremely weak digestion.
