Can the fine precipitation, which is at the top of the bottle, be avoided with the addition of Propolis MT 0.9 gr to Dextromethorfaan syrup (AD 200 ml)?

Your question is difficult to answer because I do not know which composition you use for Dextrometorfaan syrup, do you prepare it yourself?

If you prepare the syrup yourself, it might be worth trying to dilute the propolis MT with sugar syrup and then add it to the rest. I have no experience with this MT; Presumably we can only make sure that the precipitation is well mixed.

We will post the question on the website; maybe a colleague responds?
