Natural Standard Bottom Line Monograph, Copyright © 2013 (www.naturalstandard.com). Commercial distribution prohibited. This monograph is intended for informational purposes only, and should not be interpreted as specific medical advice. You should consult with a qualified healthcare provider before making decisions about therapies and/or health conditions.

While some complementary and alternative techniques have been studied scientifically, high-quality data regarding safety, effectiveness, and mechanism of action are limited or controversial for most therapies. Whenever possible, it is recommended that practitioners be licensed by a recognized professional organization that adheres to clearly published standards. In addition, before starting a new technique or engaging a practitioner, it is recommended that patients speak with their primary healthcare provider(s). Potential benefits, risks (including financial costs), and alternatives should be carefully considered. The below monograph is designed to provide historical background and an overview of clinically-oriented research, and neither advocates for or against the use of a particular therapy.

Background

  • Noni (Morinda citrifolia) is a traditional folk medicinal plant that has been used for over 2,000 years in Polynesia. Traditionally, Polynesians had many medicinal uses for noni including for fevers, headaches, malaria, bone fractures, dislocations, gastrointestinal disorders, urinary ailments, worms, wounds, rheumatism, and hypertension (high blood pressure). All parts of the noni plant were utilized.

  • Although noni is a popular supplement, few clinical trials have been conducted on its uses. There is preliminary research supporting noni's popular use as an antioxidant, but more research is needed in this area to establish noni's effects.

  • Based on scientific analysis and review of Tahitian Noni® juice, the European Commission Health and Consumer Protection Directorate-General Scientific Committee on Food found that "although some nutritional benefits are claimed for Morinda citrifolia L. products, the data supplied and the information available to the Committee provided no evidence for special nutritional benefits of Tahitian Noni® juice which go beyond those of other fruit juices."

Scientific Evidence

Uses

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.

Grade*

Antioxidant

Laboratory studies indicated that Tahitian Noni® juice (TNJ) may have greater antioxidant activity than some commonly used antioxidants. Although human study suggests that TNJ does have antioxidant effects, whether TNJ protects smokers from oxidative damage is yet to be proven. More high quality studies are needed in this area.

C

Hearing loss

Noni juice has been used for many years for a wide variety of indications in Southeast Asia, and noni juice may improve hearing in people with auditory dysfunction. Although results are promising, additional research is warranted in this area.

C

*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).

Tradition/Theory

The below uses are based on tradition or scientific theories. 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 health care professional.

  • Abscesses, addictions, allergies, analgesic (pain reliever), anthelmintic (kills intestinal/parasitic worms), antibacterial, antifungal, anti-inflammatory, antiviral, appetite stimulant, arthritis, asthma, atherosclerosis (hardened arteries), attention deficit and hyperactivity disorder (ADHD), boils, bone fractures, brain injuries, broken bones, bruises, burns, cancer, carbuncles (clusters of boils on the skin), cardiovascular disease, chemical sensitivities, chronic fatigue syndrome, chronic pain, colds, constipation, cuts, depression, diabetes, diarrhea, digestive problems, joint disorders (dislocation), ear infections, endometriosis (growth of endometrial tissue outside the uterus), energy, fever, fibromyalgia, food uses, gastric ulcers, gout (foot inflammation), headache, hemorrhoids, hernia, hypertension (high blood pressure), immune deficiency, infections, inflammation, inflammatory conditions, influenza, insect repellent, itching, intestinal worms, jaundice, jet lag, joint pain, laxative, lice, malaria, menstrual problems, mouth infections, multiple sclerosis, muscle aches, muscle pain, pregnancy (pain), rheumatism, scabies, senility, sinus disorders, sore throat, sores, sprains, sties, stiffness, stimulant (brain), stings (stonefish), stomachache, swelling (abdominal), toothaches, tuberculosis, ulcers, urinary tract disorders, vascular problems, veterinary medicine, viral infections (polio), vitamin A deficiency, weight loss, wounds.

Dosing

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 noni in adults. However, 1 ounce every 12 hours has been used. As an antioxidant 2 ounces of Tahitian Noni® juice twice daily for 30 days has been used; for hearing loss, 2 ounces of noni juice twice daily (morning and evening) for three months has been used.

  • Noni is likely safe when taken orally from preparations of fruits and leaves of the noni plant or when ≤10 grams of ripe noni fruit extract is taken daily for up to 28 days. Noni is possibly unsafe when ≥10 grams of ripe noni fruit extract is taken daily for more than 28 days.

Children (younger than 18 years):

  • There is no proven safe or effective dose for noni in children.

Safety

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.

Allergies

  • Avoid in individuals with a known allergy or hypersensitivity to noni or its constituents.

Side Effects and Warnings

  • Overall, noni has had very few reported side effects. Although noni roots are known to contain liver-damaging anthraquinones, recent research indicates that noni fruit also contains anthraquinones.

  • There is one report of acquired coumarin resistance caused by increased vitamin K intake through ingestion of a noni juice product. However, the product appeared to be vitamin K fortified and contained >115 components from several plants. (Note: Noni juice/fruit itself is not a source of vitamin K; it would therefore be unsubstantiated to draw any conclusions concerning a potential warfarin/coumarin interaction with noni from this case report).

  • Noni juice may cause elevated lactate dehydrogenase and elevated transaminases.

  • Potassium concentrations of the noni juice samples were found to be similar to potassium levels in orange and tomato juice. Patients with kidney disease may wish to avoid noni products. Effects in individuals with normal kidney function are not known.

  • Use cautiously in patients with injuries or post-surgery, as noni may have antiangiogenic properties (prevent new vessel growth).

  • Avoid in patients with gastrointestinal disorders, as noni may decrease gastric transit time.

Pregnancy and Breastfeeding

  • Noni is not recommended in pregnant or breastfeeding women due to a lack of available scientific evidence.

Interactions

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

  • Noni may decrease gastric transit time and patients taking any medication by mouth should consult with a qualified healthcare professional, including a pharmacist, to check for any interactions.

  • Based on laboratory studies, noni may prevent new vessel growth. Caution is advised when taking noni with other antiangiogenic agents.

  • Although not well studied in humans, a vitamin K-fortified juice product containing noni and >115 components from several other plants may have caused acquired coumarin resistance. Noni juice/fruit itself is not a source for vitamin K. It is unlikely that noni would interact with anticoagulants ("blood thinners"), although caution is advised.

  • Although not well studied in humans, noni roots and various noni root extracts may lower blood pressure. Noni has also shown anti-inflammatory properties, and may interact with other agents with similar effects.

  • Noni may be hepatotoxic, and caution is advised when combining with other potentially liver damaging agents. Studies have been inconclusive in this area, and clinical significance is currently unknown.

  • Noni may stimulate the immune system. It may have either no effect or suppressive effects on HIV. When taking with immune enhancing or HIV medications, additive effects may occur, although this is not yet well proven.

Interactions with Herbs and Dietary Supplements

  • Noni may decrease gastric transit time and patients taking any herb or supplement by mouth should consult with a qualified healthcare professional, including a pharmacist, to check for any interactions.

  • Based on laboratory studies, noni may prevent new vessel growth. Caution is advised when taking noni with other antiangiogenic agents.

  • Although not well studied in humans, a vitamin K-fortified juice product containing noni and >115 components from several other plants may have caused acquired coumarin resistance. Noni juice/fruit itself is not a source of vitamin K. It is unlikely that noni would interact with other herbs with blood thinning effects, although caution is advised.

  • Although not well studied in humans, noni roots and various noni root extracts may lower blood pressure. Noni has also shown anti-inflammatory properties, and may interact with other agents with similar effects.

  • Noni may be hepatotoxic, and caution is advised when combining with other potentially liver damaging agents. Studies have been inconclusive in this area, and clinical significance is currently unknown.

  • Noni may stimulate the immune system. It may have either no effect or suppressive effects on HIV. When taking with immune enhancing or HIV medications, additive effects may occur, although this is not yet well proven.

  • Noni contains 56mEq/L of potassium. In theory, noni juice may interact with other agents with high potassium content, such as orange and tomato juice.
