Respected doctors, I read article in Lybrate on haritaki, if I take about 1 table spoon of it only works for stubborn constipation but I feel very much tired otherwise suffer from unbearable constipation, previously I have tried ayurvedic, allopathic homeo etc etc no relief only haritaki gives relief but cause tiredness I tried various time to take but zeroed at 6 pm evening, it cleans strongly from 8 pm upto 9-30 pm exhausting kindly advice.
