Jojoba (Simmondsia chinensis) is a shrub native to deserts in Arizona, California and Mexico and is also found in some arid African countries. The oil (or liquid wax) in jojoba seeds contains extremely long (C36-C46) straight chain fatty acids in the form of wax esters, as opposed to triglycerides. It is this structure that allows it to be easily refined for use in cosmetics and as a carrier oil for fragrances. Jojoba meal, remaining after oil extraction, is rich in protein. In Japan, jojoba oil (wax) is used as a food additive.

Jojoba oil is used most commonly as a carrier oil for topical application or aromatherapy. At this time, there are no high-quality human trials available supporting the efficacy of jojoba oil for any indication. Potential effects of jojoba oil include anti-inflammatory, cholesterol-reduction and mosquito-repellant effects.



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.


Jojoba oil is traditionally used as a carrier or massage oil. There is currently not enough available evidence to recommend for or against the use of jojoba oil for dementia.


Mosquito repellent

There is currently not enough available evidence to recommend for or against the use of jojoba oil as a mosquito repellent.

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 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.

Anti-aging, anti-inflammatory, appetite suppressant, cosmetic uses, food uses (additive), insecticidal, reflexology treatment, skin disorders (dry skin), topical (applied to the skin) drug delivery, weight loss, wound-healing.


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.


There is no proven safe or effective dose for jojoba in adults. Avoid taking jojoba products by mouth.


There is no proven safe or effective dose for jojoba in children. Avoid taking jojoba products by mouth.


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.


Side effects of jojoba are mainly limited to contact dermatitis and gastrointestinal concerns in animals fed large amounts of jojoba meal. Avoid oral consumption of jojoba products.


Jojoba is not recommended in pregnant or breastfeeding women due to a lack of available scientific evidence. Although not well studied in humans, ingesting jojoba meal may lower fetal and placental weights.


    • Jojoba liquid wax may have anti-inflammatory effects. Thus, cautioun is advised when taking jojoba with other anti-inflammatory herbs or supplements.

    • Although not well studied in humans, jojoba oil may alter blood cholesterol levels. Caution is advised when combining with other cholesterol-lowering herbs or supplements, such as red yeast rice.

    • Consumption of jojoba meal in combination with appetite suppressant herbs or supplements may have additive effects.

    • Jojoba oil is commonly used as a carrier oil in aromatherapy. Combinations with other carrier oils, such as almond and apricot, with the essential oils from lavender, marjoram, eucalyptus, rosemary and peppermint, may offer clinical benefits.

    • A South African commercial oil containing coconut, jojoba and rapeseed oils has shown ability to act as a mosquito repellant. Thus, use of jojoba oil in combination with other mosquito repellant herbs may have additive effects.
