  • Note: This monograph focuses on black mulberry (Morus nigra), but due to the lack of information on this species, some related species information has been included.

Background

  • Mulberry is native to China and became naturalized and hybridized in Europe and America centuries ago. Indian mulberry (Morinda tinctoria) is reportedly used by the African aborigines medicinally, but there is no reliable evidence of its therapeutic value. In India, the root-bark of Morus alba, known locally as san-pai-p’i, is used as a diuretic (increasing urine flow) and expectorant (an agent that increases bronchial secretions and facilitates their expulsion through coughing, spitting or sneezing).
  • Herbalists have used mulberry fruit for oral infections. The bark of Morus nigra is also a reputed anthelmintic (medication) for tape worms.
  • At present, black mulberry (Morus nigra) is most commonly used for its antioxidant properties. It is also popularly used in the preparation of flavored syrup used in medicine and as a laxative in the treatment of constipation. Black mulberry has been indicated for a variety of other conditions, though all indications lack sufficient scientific data supporting their safety and efficacy at this time. Further research in these areas is warranted before firm conclusions can be drawn.

Evidence Table

    Disclaimer

    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.

*Key to grades:

Tradition

    Disclaimer

    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.

Dosing

    Disclaimer

    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)

    • Based on the available scientific evidence, there is no proven safe or effective dose. Traditionally, 2-4 milliliters of mulberry syrup or 4.5-15 grams of powder or decoction has been used.
  • Children (younger than 18 years)

    • There is not enough scientific evidence to safely recommend the use of black mulberry in children.

Safety

    Disclaimer

    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 use of black mulberry in individuals with a known allergy or sensitivity to white, red, purple or black mulberry (Morus spp.) or the Moraceae family. Individuals allergic to fig or any member of the Ficus family may also be cross-sensitive to mulberry.
  • Side Effects and Warnings

    • There is currently no scientific evidence on the medicinal uses of black mulberry, and information about safety and side effects is limited. There have been no known adverse effects reported, and black mulberry is assumed to be likely safe when used in food amounts in healthy patients.
    • In theory, patients with impaired liver function or diabetes should use black mulberry cautiously.
  • Pregnancy and Breastfeeding

    • The use of black mulberry during pregnancy or breastfeeding is not recommended due to a lack of available scientific evidence.

Interactions

    Disclaimer

    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

    • Black mulberry may interfere with the way the body processes many drugs using the liver’s “cytochrome P450” enzyme system. As a result, the levels of these drugs may be increased in the blood in the short-term (causing increased effects or potentially serious adverse reactions), and/or decreased in the blood in the long-term (which may reduce the intended effects). Examples of medications that may be affected by black mulberry in this manner include: carbamazepine, cyclosporin, irinotecan, midazolam, nifedipine, birth control pills, simvastatin, theophylline, tricyclic antidepressants, warfarin, or HIV drugs such as non-nucleoside reverse transcriptase inhibitors (NNRTIs) or protease inhibitors (PIs).
    • Black mulberry may alter blood sugar levels. Caution is advised when using medications that may lower blood sugar. Patients taking drugs for diabetes by mouth or insulin should be monitored closely by a qualified healthcare professional. Medication adjustments may be necessary.
    • Black mulberry may increase the amount of drowsiness caused by some drugs. Examples include benzodiazepines such as lorazepam (Ativan®) or diazepam (Valium®), barbiturates such as phenobarbital, narcotics such as codeine, some antidepressants, and alcohol. Caution is advised while driving or operating machinery.
  • Interactions with Herbs and Dietary Supplements

    • Black mulberry may interfere with the way the body processes certain herbs and supplements using the liver’s “cytochrome P450” enzyme system. As a result, the levels of these drugs may be increased in the blood in the short-term, causing increased effects or potentially serious adverse reactions, or decreased in the blood in the long-term, which may reduce the intended effects. Black mulberry may alter blood sugar levels. Caution is advised in patients with diabetes or in those taking herbs and supplements that may also alter blood sugar levels.
    • Black mulberry may increase the amount of drowsiness caused by some herbs or supplements, such as chamomile. Caution is advised while driving or operating machinery.
