Health Concerns
Ligustrum has been used in connection with the following conditions (refer to the individual health concern for complete information):
Rating Health Concerns Immune function
InfectionReliable and relatively consistent scientific data showing a substantial health benefit.
Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
An herb is primarily supported by traditional use, or the herb or supplement has little scientific support and/or minimal health benefit.
Traditional Use
Historical or traditional use (may or may not be supported by scientific studies)
Since ancient times, ligustrum berries have been employed as a "yin" tonic in Traditional Chinese Medicine.1 Ligustrum was used for a wide range of conditions, including premature aging and ringing in the ears.2
Active Constituents
Active constituents
The major constituent in ligustrum is ligustrin (oleanolic acid). Preliminary studies, mostly conducted in China, suggest that ligustrum stimulates the immune system, decreases inflammation, and protects the liver.3 Ligustrum is often combined with astragalus in Traditional Chinese Medicine. Although used for long-term support of the immune system in people with depressed immune function or cancer, more research is needed to demonstrate the optimal length of time to use ligustrum.
Dosage
How much is usually taken?
Powdered, encapsulated berries, 1-3 teaspoons (5-15 grams) per day, are sometimes recommended.4 A similar amount of berries can be made into tea by adding 1/2-1 teaspoon (2-5 grams) of powdered or crushed berries to 1 cup (250 ml) of boiling water and steeping for ten to fifteen minutes. Alternatively, 3/4-1 teaspoon (3-5 ml) of tincture three times per day can be taken.
Side Effects
Are there any side effects or interactions?
No adverse effects have been reported.
At the time of writing, there were no well-known drug interactions with ligustrum.
