This 1 oz tincture is alcohol based.  This handy tincture always finds it way into my travel bag, especially when venturing into countries with questionable drinking water. This astringent tincture may help relieve diarrhea.
 
Suggested usage:   Put a dropperful under your tongue and hold for 30 seconds or add to a drink whenever needed.
