There is a popular saying in Tamil that, "உணவே மருந்து". Meaning the food we eat itself is a medicine. Rasam is the dish which is apt for the above saying. I remember my grandma making rasam almost all the days for lunch. I am fond of drinking the rasam, which my kid follows too:-)
The Pepper, Cumin, Garlic, Tomato, Tamarind syrup, and the coriander leaves, will make wonders in ailing your digestion. Want to treat your cold and cough without seeking doctor, then having rasam for a week along with cooked rice will help you. This helps in relieving constipation and gastric problems also. The first baby food with rice will be mashed rasam rice in my native regions.
