Turmeric has many actions, from relieving pain to improving circulation - which is why healers in Asia have been using it for more than 5,000 years. Some of the uses of turmeric include: soothing digestive problems, topical wound healing, stimulant to improve blood flow, topical paste for skin problems and decongestant to clear nasal passages. (Aggarwal 2011)
Today, turmeric is considered as the Super Star of spices for its anti-oxydant properties and has been extensively studied in a wide range of applications (Gupta 2013).
Worldwide 48 clinical trials using curcumin are underway.
