Hello Amy,
I have not used this herb but here is some info that you may find helpful. 
The Turmeric plant, though long used as an important coloring agent for curries and other foods, is also an important medicinal herb, used by both Chinese and Ayurvedic medicine practitioners.
Turmeric plant is used to treat a number of medical disorders, including digestive disorders, liver problems, and skin diseases. It has also been proven effective in stimulating improvement in bile flow, making it very beneficial for people suffering for both digestive and gall bladder problems.
Anytime you are considering using a herbal supplement I would consult your physician as some of these herbs may interact with other medications you may be on.
On HealingWell we strive to seek a balance between alternative and traditional approaches. I feel strongly, both approaches have value for anyone seeking healing.
Take care and stick with us.
