I think in India, hingoli is very popular....after every meal, indians take hingoli to avoid digestion and gastric problems. The best thing about hingoli is no side effects. It is ayurvedic medicine and hence no side effects.
Since last 18 months, i have been taking hingoli regulary- 4 tablets a day with water. I think it has improved my digestion.
They have more digestive products like hajmola and pudina hara but i find hingoli the best.
Just one thing- If you are starting to take hingoli, it has a extremely strong taste. I can not bother to stand hingoli taste. So i gulp 4 hingoli tablets with water every afternoon !
