This is a thickening agent used for people who have difficulty swallowing. By thickening liquids and foods with high liquid content, it makes swallowing easier and prevents food and liquids from entering the trachea by mistake. I bought too much, so I'm selling it. I purchased it in November of this year. It's new and unused, but it's been stored personally. There are 100 sticks in 2 bags. No individual sales.
