It seems we need probiotic and certain enzymes in our gut to make it function properly. In allopathy, they have supplements for this. How does Ayurveda promote this. I am aware of curd and butter milk snd also about fermented foods like idli dosa. I have problem with curd and butter milk. They give me severe headache and urad dal also puts too much load in my digestion. Would like to know natural methods by which I can improve my gut flora.
