BLACK RICE Overview Information

Black rice is a type of rice that contains high amounts of certain antioxidants. This gives the rice its characteristic black color. Black rice is eaten as food and taken as medicine.

People use black rice for aging, heart disease, cancer, and many other conditions, but there is no good scientific evidence to support these uses.

How does it work?

Black rice contains high levels of antioxidants which may help reduce swelling.

BLACK RICE Uses & Effectiveness

Insufficient Evidence for:

Aging. Early research shows that taking a drink prepared with a black rice powder while participating in an exercise program can improve walking speed and balance. But it might not be any better than exercise alone.
Heart disease. Early research shows that eating black rice does not change cholesterol or triglyceride levels in people with heart disease.
Cancer.
Decline in memory and thinking skills that occurs normally with age.
Eczema (atopic dermatitis).
Hay fever.
High levels of cholesterol or other fats (lipids) in the blood (hyperlipidemia).
Swelling (inflammation) of the main airways in the lung (bronchitis).
Other conditions.

More evidence is needed to rate the effectiveness of black rice for these uses.

BLACK RICE Side Effects & Safety

When taken by mouth: Black rice is LIKELY SAFE for most people when consumed in amounts commonly found in foods. Black rice is POSSIBLY SAFE when used in larger amounts as medicine.

Special Precautions & Warnings:

Pregnancy and breast-feeding : There isn't enough reliable information to know if black rice is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.

BLACK RICE Interactions

We currently have no information for BLACK RICE Interactions

BLACK RICE Dosing

The appropriate dose of black rice depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for black rice. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
