Some have alcohol, where as others are glycerin extracts. The ones with alcohol have less alcohol than a ripe fermented banana in the recommended dosage if used as directed.  They are safe for kids to use as long as a parent administers it. If the taste bothers you, the alcohol will evaporate with heat and can be diluted more.  Please indicate if you are in recovery or have Religious beliefs that prohibit you from taking alcohol. Dr. Roberts will consider this in developing your formula.
