I'm taking prograf immunosuppressants, since my kidney transplant two years ago. I suffer from diabetes and have athritis of the knees. As one of the effects of Prograf is to raise blood sugar levels, research has shown that turmeric (ginger type root powder) reduces this. It is also an anti-inflamatory and therefore would help with my knees. It increases levels of tacrolimus in the blood. Therefore, it could mean a reduction in the dose of Prograf and therefore less side effects. I've heard that I should not take more than a teaspoon of turmeric on a daily basis. Before I embark on this, has anyone had any experience of using turmeric? Has it worked out well?
