Gardenia is a plant. The fruits are used to make medicine.

People take gardenia by mouth for anxiety, agitation, bladder infection, bleeding, cancer, constipation, depression, diabetes, fever, gallbladder disease, high cholesterol, high blood pressure, the flu, trouble sleeping, liver disorders, menopausal symptoms, pain, swelling of the pancreas, and rheumatoid arthritis. It is also used as an antioxidant, to reduce swelling, and to improve the immune system.

Gardenia is applied to the skin for bleeding, wound healing, sprains, and muscle soreness.

In food, gardenia is used as a yellow food colorant.

How does it work?

Some chemicals found in gardenia might reduce insulin resistance and help prevent glucose intolerance. Gardenia extract might also reduce swelling, lower blood fats and cholesterol, protect the liver, and help treat viral infections.

Special Precautions & Warnings

Pregnancy and breast-feeding: Not enough is known about the use of gardenia during pregnancy and breast-feeding. Stay on the safe side and avoid use.


Stimulant laxativesInteraction Rating: Moderate Be cautious with this combination.Talk with your health provider.

Gardenia contains chemicals that speed up the bowels. Stimulant laxatives speed up the bowels. Taking gardenia along with other stimulant laxatives might speed up the bowels too much and cause dehydration and low minerals in the body.

Some stimulant laxatives include bisacodyl (Correctol, Dulcolax), cascara, castor oil (Purge), senna (Senokot), and others.


The appropriate dose of gardenia 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 gardenia. 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.
