Ziziphus (Ziziphus spp., Zizyphus spp.)
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.
Ziziphus species are a group of spiny shrubs and small trees related to buckthorn. Plants may be found in many different warm and near-tropical regions, including Asia (China, India, Korea, Saudi Arabia), Africa (Morocco, Egypt), South America (Brazil), and Europe (the Mediterranean). Similar to dates, Ziziphus fruit often tastes sweet and sugary.
Early use of Ziziphus species reportedly dates back 2,000 years, to the Han Dynasty in China. According to traditional medicine practices, it is well known for its calming and sleep-promoting effects. Either alone or mixed with other herbs, Ziziphus species have been used to treat conditions such as diarrhea, erratic blood pressure, excess worrying, fevers, lack of sleep, menopausal symptoms, mental fatigue, nighttime emissions, sleepiness, and ulcers.
Limited research in humans suggests that Ziziphus species may be effective for treating insomnia, nighttime emissions, and stress. More research is needed in these areas as well as on the effects of Ziziphus species alone.
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.
Suan Zao Ren Tang is a combination product containing Ziziphus spinosa and various other herbs. Early research suggests it may be useful in treating lack of sleep. However, the effects of Ziziphus spinosa alone are unclear. Further research is needed in this area.
Limited research suggests that herbal supplements containing Ziziphus spinosa may improve mood in teenage girls. More research with Ziziphus alone is needed in this area.
|Sexual disorders (nighttime emissions)
Suan Zao Ren Tang is a combination product containing Ziziphus spinosa and various other herbs. Early research suggests it may be useful in treating nighttime emissions. Further research is needed in this area, as the effects of Ziziphus spinosa alone are not clear.
*Key to grades:
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.

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)
For general use, Ziziphus mauritiana has been taken by mouth as candy. The exact dose taken has not been clearly stated.
For burns, a liquid treatment containing Ziziphus vulgaris cortex (powdered and mixed with 80% alcohol at a 1:2 ratio) has been applied to the skin.
Children (under 18 years old)
There is no proven safe or effective dose for Ziziphus species in children.
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 people with a known allergy or sensitivity to Ziziphus species.
Avoid in people with a known allergy or sensitivity to latex. Some people with latex allergy may also have a related allergy to various plant products, including Ziziphus fruit. This relationship is called latex-fruit syndrome. Ziziphus mauritiana is known to contain Ziz m 1, which is a compound involved in latex-fruit syndrome.
Side Effects and Warnings
Ziziphus fruits are likely safe when eaten in normal dietary amounts. Ziziphus species should be purchased from well-trusted sources, and the fruit should be washed carefully before use. Low levels of toxic compounds have been found on Ziziphus jujube fruits.
Ziziphus species may lower blood sugar levels. Caution is advised in people with diabetes or hypoglycemia, and in those taking drugs, herbs, or supplements that affect blood sugar. Blood glucose levels may need to be monitored by a qualified healthcare professional, including a pharmacist. Medication adjustments may be necessary.
Ziziphus may cause high or low blood pressure. Caution is advised in people taking agents that affect blood pressure.
Use cautiously when combined with prednisone, antidepressants, or agents that lower immune system activity.
Although it has not been well studied in humans, the extract of Ziziphus jujuba bark may lower a woman’s ability to have children. Use cautiously in women trying to conceive.
Avoid in people that are unable to sleep. Cases of chronic cough with yellow sticky mucus have been reported.
Drowsiness or sedation may occur. Avoid use if driving or operating heavy machinery.
Avoid use of amounts higher than those normally found in the diet in children and pregnant or lactating women, due to a lack of safety information.
Avoid with known allergy or sensitivity to Ziziphus species or latex.
Pregnancy and Breastfeeding
There is currently a lack of scientific evidence on the use of Ziziphus species during pregnancy or lactation. The use of amounts higher than those normally found in the diet should be avoided during these periods.
Although it has not been well studied in humans, Ziziphus jujuba bark may lower a woman’s ability to have children. Use cautiously in women trying to conceive.
Most herbs and supplements have not been thoroughly tested for interactions with other herbs, supplements, drugs, or foods.
