Arrowroot is a plant. People use starch taken from the root and rhizome (underground stem) to make medicine.
Arrowroot is used as a nutritional food for infants and for people recovering from illness. It is also used for stomach and intestinal disorders, including diarrhea.
Some people sooth painful gums and sore mouth by applying arrowroot directly to the affected area. Babies cut teeth on arrowroot cookies.
In foods, arrowroot is used as an ingredient in cooking. Arrowroot is often replaced with cheaper starches, including potato, corn, wheat, or rice starch.
How does it work?
There is some scientific evidence that arrowroot may help get rid of cholesterol in the body. There isn't enough information to know how it works for stomach and intestinal problems or for other uses.

QUESTION
Next to red peppers, you can get the most vitamin C from ________________. See AnswerInsufficient Evidence to Rate Effectiveness for...
- Intestinal problem (irritable bowel syndrome, IBS). Early research suggests that taking powdered arrowroot three times per day with meals for one month reduces stomach pain and diarrhea in people with IBS.
- Soothing mucous membranes, such as the mouth and gum linings.
- Other conditions.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).

SLIDESHOW
Vitamin D Deficiency: How Much Vitamin D Is Enough? See SlideshowThe appropriate dose of arrowroot depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for arrowroot. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
