तयाप्रवाहितेदोषेप्रशाम्यत्युदरामयः । जायतेदेहलघुताजठराग्निश्चवर्धते ॥१८॥
6. If the diarrhea is associated with griping pain (difficulty in evacuating), then haritaki should be given as a mild laxative. 7. Once the morbid matter is eliminated through downward movement then this abdominal disease (diarrhea) gets cured, the body becomes light and the power of agni becomes strong.
