Was trying to get a beverage to replace Coffee. Bournvita, Horlicks, Complan, Proteinex have tons of sugar (almost like Chywanprash). I am sure foodpharmer2 became an influencer dishing them (and Glucose biscuits).
True Chywanprash is full of sugar. There are sugar free versions too. If you are giving it to children, you need not worry about the sugar.
Chywanprash is good for coughs and colds.
I think Ayurveda has a lot of good products which are very good as a preventive. True they do not have evidence (RCTs), but they have been used for hundreds of years.
Not sure if Pediatricians recommend flu vaccines for children. Cost Rs.1500. I think you can get 2-3 good Chywanprash bottles.
I am planning to buy one tomorrow.
