Its flower fragrance is rich and can be used for wearing flap flowers; fruit can be used as yellow dye; wood is fine and can be carved; roots, leaves and fruits can be used as medicine. It has the effect of heat-clearing and detoxification, cooling blood and purging fire.

From this point of view, gardenia is not poisonous. Botanical experts also support this view: gardenia is not only non-toxic, but also effective:

Southern Yunnan Materia Medica called it "purging lung fire, stopping lung heat, coughing, stopping epistaxis and eliminating phlegm."
