Does a cough syrup with honey break veganism?
Short answer
The definition talks about possibility and practice. Medicine you need is not a purity test. If a honey-free equivalent exists, it is fine to choose it. Do not drop treatment for a label.
This is a values-plus-health axis, not a fact that “honey in syrup = moral collapse”.
This is not medical advice. Ask a pharmacist about the ingredients if you want a honey-free version.
