Turmeric tea is considered safe for most people to drink. It can relieve pain and inflammation without the side effects that even over-the-counter medications like NSAIDs can cause, such as internal bleeding, ulcers, and reduced white blood cell count.
Almost anyone can benefit from drinking turmeric tea, especially because it can boost the immune system and act as an anticancer agent. People with pain caused by inflammation can perhaps benefit the most. People who have diabetes or who take blood thinners should talk to their doctors before trying any turmeric supplement, however.
