Gum arabic
Gum arabic


Gum arabic is the gum that is exuded from certain trees, such as the Acacia senegal tree. It's a source of dietary fiber that can dissolve in water.

Gum arabic tends to make people feel full, so they might stop eating earlier than they otherwise would. This might lead to weight loss and reduced cholesterol levels.

Gum arabic is used for high cholesterol, diabetes, irritable bowel syndrome (IBS), and other conditions, but there is no good scientific evidence to support these uses.

Don't confuse gum arabic with Acacia rigidula, acai, or cassie absolute (Acacia farnesiana). These are different plants with different effects.
When taken by mouth: Gum arabic is likely safe when consumed in amounts commonly found in food. Gum arabic is possibly safe when taken as medicine. Up to 30 grams daily has been used safely for 6 weeks. It can cause minor side effects, including gas, bloating, and nausea.
