The Buttered Veg blog has some of the most comprehensive content about turmeric on the Internet, particularly as an ingredient in recipes.
Turmeric is unique in that it is one of the few medicinal foods to be studied extensively by modern scientists.
Scientists have primarily been interested in curcumin, which is the primary active ingredient in turmeric.

Inflammation is a factor in allergies, asthma, autoimmune diseases, cancer, hepatitis, diabetes, inflammatory bowel disease, kidney disease, osteoporosis, and many, many more conditions that ail us.
If you are interested in using turmeric as medicine for a specific ailment, you should consult with a doctor before ingesting large amounts of it in capsule form.
In the meantime, you could test the effect of turmeric on your health by trying my turmeric elixir cure-all recipe, or by adding it to your food.
