The name "acacia" is derived from the Greek word "akis" meaning "sharp point," and relates to the sharp thorny shrubs and trees of tropical Africa and Western Asia that were the only known acacias at the time that the name was published. The Australian acacias are commonly called "wattles" because of their pliable branches that were woven into the structure of early wattle houses and fences.
Acacia is commonly present in chewing sticks, mainly as an antimicrobial with activity against Streptococcus fecalis. Acacia has also shown some cholesterol-lowering and antidiabetic properties, although there is insufficient evidence in support of these uses.
Acacia is generally considered to be safe. Adverse reactions appear to be mild, with occasional gastrointestinal symptoms.
Acacia has been used to treat high cholesterol, diabetes, cancer, gingivitis, stomatitis (mouth sores), pharyngitis, and indigestion in children. Acacia gum is used as a food additive. Acacia concinna is often used in cosmetics.
These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.
The available data shows promising results; however further studies are warranted.
Hypercholesterolemia (high cholesterol)
There is preliminary evidence that acacia may not be helpful for hypercholesterolemia.
*Key to grades:
A: Strong scientific evidence for this use;
B: Good scientific evidence for this use;
C: Unclear scientific evidence for this use;
D: Fair scientific evidence against this use (it may not work);
F: Strong scientific evidence against this use (it likely does not work).
The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below. Astringent, blood clots, cancer, contraception, cosmetic, dandruff, diabetes, flavoring agent, food additive, gingivitis, hepatitis, HIV, indigestion, infection, inflammation, leprosy, lice, parasites (visceral leishmaniasis), pharyngitis, renal failure, sexually transmitted diseases (Acacia nilotica), stomatitis (mouth sores).
The below doses are based on scientific research, publications, traditional use, or expert opinion. Many herbs and supplements have not been thoroughly tested, and safety and effectiveness may not be proven. Brands may be made differently, with variable ingredients, even within the same brand. The below doses may not apply to all products. You should read product labels, and discuss doses with a qualified healthcare provider before starting therapy.
Adults (18 years and older)
There is no proven safe or effective dose for Acacia. Traditionally, 5 grams twice daily for four weeks has been used.
Daily use of a chewing stick of Acacia arabica may be effective for plaque; studies have shown positive results in as little as seven days.
Children (younger than 18 years)
Insufficient available evidence.
The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.
Avoid in individuals with a known allergy or hypersensitivity to acacia or the Fabaceae or Leguminosae family. There is cross-sensitivity between acacia and rye grass pollen allergens and date palm.
Avoid in individuals with a known allergy or hypersensitivity to pollen, particularly mimosa, other pollens, bee pollen, other inhalants and foods containing related substances.
Side Effects and Warnings
Acacia gum is regarded as safe when used orally and in amounts commonly found in foods. Acacia has generally recognized as safe status (GRAS) for use in foods in the United States.
When sucked or chewed, acacia may cause gastrointestinal disturbances and neurological side effects.
Allergic reactions including asthma, rhinitis, conjunctivitis and rash may occur.
Acacia senegal can cause minor gastrointestinal disturbances such as bloating, loose stools, and flatulence. Side effects may diminish with continued use.
Iridocyclitis, a type of anterior uveitis, can be caused by acacia thorns.
Use cautiously in patients taking amoxicillin or iron.
Use cautiously in patients with respiratory disorders
Be aware that the fiber of acacia may impair the absorption of oral drugs.
Be aware that tannins from Acacia catechu L. plant may contribute to oral and esophageal cancer when combined with other substances that also contain high amounts of tannins.
Pregnancy and Breastfeeding
Acacia is not recommended in pregnant or breastfeeding women due to a lack of available scientific evidence.
Most herbs and supplements have not been thoroughly tested for interactions with other herbs, supplements, drugs, or foods. The interactions listed below are based on reports in scientific publications, laboratory experiments, or traditional use. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy.
Interactions with Drugs
Acacia may affect the absorption of amoxicillin when taken concurrently; doses should be separated by at least four hours.
Use of acacia as a surfactant (substance that lowers surface tension) may increase the intestinal absorption of some anticancer drugs.
Mixing acacia with a substance containing more than 50% concentration of ethyl alcohol may cause acacia to become insoluble.
Acacia can be gelatinized by solutions of iron salts.
Theoretically, the fiber in acacia may impair the absorption of oral drugs.
Interactions with Herbs and Dietary Supplements
Theoretically, the fiber in acacia may impair the absorption of oral herbs and supplements.
Theoretically, tannins from Acacia catechu L. plant may contribute to oral and esophageal cancer when combined with other substances that also contain high amounts of tannins.
