I have used turmeric for a couple of years. I buy the pure turmeric in bulk at this wonderful little shop in town where everything is fresh and pure and make it into capsules. Turmeric is also in the two anti-inflammatory herbal compounds I take, Zyflamend and Mobility Essentials. Sadly, it has not lived up to its promise in my case. I talked about this to my doctor, who has a doctorate in Naturopathy, and he felt that the effects of the herb were overrated, although it seems to works synergisticly with other herbs.
