It is a syrup and is filled with various ingredients, including a lot of sugar. I’m not sure how efficient it is. For a child in Cuba who has a respiratory condition, a friend of mine fervently requested this product. The farmer father who made the request came prepared with an empty syrup bottle for reference. The father was eager to get it because his child seems to enjoy it a lot. So, I hope. Although I don’t practice medicine, how can one refuse such a request? The expensive item was given away.
