Thanks Hv,but is the grocery store powdered turmeric any good?And does cooking with it gives the same benefits as just downing a dose in juice?

I have purchased turmeric from stores on occasion and it was pretty good.  And I have seen other turmeric in stores that looked anemic and has probably been sitting there a few years too long.  If you do get it from a store check the color.  It it a rich color?  If in a package can you smell it?  Does it have the strong characteristic odor of turmeric.  If it has good color and smell then it is going to be relatively fresh.

Although if you have the chance buying from herb supply companies, especially ones that do wholesale as well, is your best bet.  They will have a quicker turnover with their herbs meaning the herbs are much more likely to be fresh.  Buying this way also tends to be considerably cheaper than buying spices from grocery stores.

 Thanks MissCast,the only thing I know to put it in is curry but what I'm wondering is if heat would kill the good stuff.I guess I can be a bit more adventurous with it.

You will lose some of the volatile oils and vitamins from heat, so keep its exposure to high heat at a minimum.  The heat should not affect the curcumin though, which is generally considered the active component.
