I couldnt find reliable information about COUFRELIV Ayurvedic Syrup by that name. Its possible there is a spelling error or it might be a lessknown/local brand.
Heres what I suggest:
Check spelling / alternative names
It might be a variant or miswriting of Cofreliv, Cofreliv, Cofreliv Syp, Cofrelive, etc. Also Cough + Liv(ing) or similar. Try checking the label or the pharmacy for the exact name.
Ask a pharmacist / check packaging
The package may list the manufacturer, batch number, ingredients. That will help identify it.
Use safer, known alternatives
Meanwhile, if your aim is relief of cough or respiratory symptoms, you can use known Ayurvedic cough syrups (with doctors/herbalists advice) such as Charak Kofol which is well documented.
