Recently i picked up an item which included white wine vinegar as an ingredient. After making enquiries i was told its not permissible to use such an item. However while talking to someone about this particular item i was told that one should not be so particular about everything, and this person feels that its permissible to use since its not been used as an intoxicant (the example of alcohol in medicines was given to me). Is this true? and if not, how do you respond to such a person?
