Gardenia tea can be used for yin deficiency disorders, which include irritability, restlessness, sensations of tightness in the chest and insomnia. Gardenia is also used in formulas to treat anxiety and insomnia. Menopause can cause these symptoms, and menopausal women can also consume gardenia tea to alleviate related symptoms, such as depression, headaches and dizziness. As with all herbal remedies, a physician should be consulted prior to using gardenia tea to treat health disorders.
Gardenia is often used in Chinese herbal formulas to treat bladder infections and painful urinary dysfunction resulting from damp-heat syndrome, which disturbs the function of the bladder, according to the Institute for Traditional Medicine. Gardenia has been used for centuries in traditional Chinese medicine, but there is no Western scientific research available that supports the use of gardenia for these health disorders.
