I just bought this one for my 10 year old daughter yesterday. She has runny nose for 4-5 years. I take her to see doctor on and off. But No use. Last night I gave her twice table and this morning no runny nose. The sales lady said try to decrease to 1 tablet a day later and eventually no need to take this. Her experience is 6 months to build up your body condition.
Not expansive product. Can give a try. I m not the promotor of this product. Just a regular consumer. I just hope this can help some people.
